Multi-Domain

Each platform user has an Account created inside the CommuniGate Pro Server user database. The Account name looks like userName@domainName, and it becomes the user’s E-mail, Calendar, SIP, and XMPP address.Each Account (such as john@company.dom) belongs to some Domain (company.dom in this case). CommuniGate Pro Server supports multiple Domains, each with its own independent set of Accounts, Groups, Aliases, and other Objects, its own set of Default Account settings, own set of E-mail and Signal Rules, own security Certificates, etc.A Domain can have its own dedicated IP address(es), or several Domains can share the same IP address(es).When the platform is used for hosting, each Domain can be administered remotely by Domain Administrators - Accounts in that Domain with administrative rights granted to them.

In the case where the

platform used to host each domain can be controlled remotely by using Domain Admins - accounts with administrative rights

CommuniGate Pro is the most scalable E-mail server (by the Spec.org tests) and the most scalable VoIP solution (by the published tests) on the market.Running on a medium size server hardware, the CommuniGate Pro Server can support from 10,000 to 200,000 users (depending on the usage pattern).Partitioning («Static Cluster») and the unique Dynamic Cluster architectures can be used to build multi-server «farms» with virtually unlimited scalability.

Many CommuniGate Pro Cluster installations all over the world serve several million users each, while the Single Service Image technology makes multi-server Clusters as easy to manage as a simple Single-Server system.

Unlike traditional «partitioning» systems, the Dynamic Cluster provides reliable service to all Accounts and their users even when several of its servers experience software or hardware failure.The most sophisticated Dynamic Cluster and SIP Farm technologies require generic commodity server hardware, the simplest Load Balancers, and generic off-the-shelf Shared File Storage, such as NFS servers or Cluster File Systems.

Dynamic cluster CommuniGate Pro

CommuniGate Pro Dynamic Cluster implements the architecture in which all nodes are «active». Many other solutions are content recovery schemes after a fall or by hot-swap. But it is not a dynamic cluster. In it, all systems working together as a single logical entity, and each node assumes a certain part of the total load.

At the same time, each node at any moment can be retrieved of the cluster. Or add a new, with the role. Thus, the dynamic cluster service allows any of its members, and to increase (or decrease) of power directly involved while working without interruption in the provision of services.

The key advantages are a dynamic cluster:

3 Maintenance units without stopping service 3 Uniform System 3 server utilization 3 Predictable scalability low overhead 3 High Availability Services

Dynamic Cluster - an elegant solution, with no extra costs growing with your user base

Maintenance nodes without stopping the service updatesMaintenance nodes without stopping the service updates of software and hardware at the sites can dramatically reduce the time availability of the communication system. In the world of corporate IT, these overlays are often called «planned outages». Unfortunately, this trip totally unacceptable in the area of SaaS-solutions operator level.

Imagine a situation in which the cable to the phone disconnected for service on Saturdays. In order to avoid having to shut down, in a dynamic cluster mechanism implemented successive updates. This mechanism allows an administrator to disable the cluster node while distributing open connections to other members of the cluster as long as the unit is not completely gone offline. Thereafter, it is available for service, and further it can be returned back to the cluster.

Unified systemCommuniGate Pro Dynamic Cluster allows the operator to treat the entire system as a single entity, even if it consists of more than 40 servers. Thus, management of a large-scale infrastructure becomes several orders simpler than in the case of enterprise-level systems. SaaS-providers providing services for small businesses and individual entrepreneurs, we need a highly scalable system. And for our customers, using dynamic cluster, become quite commonplace clouds, serving more than 20,000 small (5-30 end users) companies. At the same time, in the case of the IP PBX and messaging solutions that are not designed with a view to use as a SaaS-platform, with the growth of user base management becomes much more complicated. This is due to the fact that the number of parts increases: proxy servers, databases, LDAP -server, media gateways, etc.

Tecnological solutions 29

EffectivenessThe platform CommuniGate Pro is extremely efficient use of hardware resources. As a consequence, the provider is able to achieve a much higher density of users per server compared with corporate decisions. The density of users is critical in data centers as it gives an opportunity to significantly reduce administration costs, electricity and cooling.

Предсказуемая масштабируемостьPredictable Scalability Dynamic Cluster - a system with minimal overhead on the scale. To increase the capacity of the system rather simple cheap servers, 1U and blade servers. Unlike other architectures with high demands on computing power CommuniGate Pro does not use too powerful servers (such as 8-way). Thus, when using a dynamic cluster 4 x 4 with two-processor servers specific load on each server below. Since the source code CommuniGate Pro is well parallelized computational resources and memory are used with maximum efficiency. As a result, forecasting the volume of the necessary resources by increasing the user base is transparent and close to a linear relationship. All nodes in the cluster CommuniGate Pro is used the same executable file. And that is why there are no differences in the performance of nodes characteristic of heterogeneous architectures.

The elegant structure is dynamic cluster allows providers to analyze and predict their own costs accurately, whether a server or a data warehouse

note

On most 64-bit systems, carrier-class (Solaris, Linux, BSD) CommuniGate Pro can reach 90 000 sessions per system. There are also proven operating configurations for more than 450,000 end-users on a single system.

High availabilityOne of the main features and objectives of the development of a dynamic cluster is to reduce to zero the time a lack of service. All cluster nodes are active, and the fall of one of them the other members of the cluster take on the user load.

The architecture of the dynamic cluster

The main elements of the cluster architecture CommuniGate Pro include:

• Load Balancer• Network Topology• Frontend• The backend• Shared storage type NFS / CFS

Certainly important coordinated work of all elements of the system.Let us a little more detail on each of them.

Technological solutions

Технологические решения

Load BalancerThe cluster includes multiple servers, so that users can go to him one URL or IP-address, you need a load balancer. In the world there are many working dynamic clusters, and they used a variety of balancers. We recommend using only high quality device with good bandwidth offered by Cisco, F5, Foundry. More detailed information on configuration is available in the manual balancers. In addition, frontends for Linux themselves can serve as balancers using technology built into the kernel IPVS.

network TopologyThe organization of dynamic cluster uses at least four separate networks and several high-speed switches for optimal performance. We recommend Cisco, F5, Foundry, HP, or other similar level switches that provide Gigabit speed. And it should be very simple and reliable device.

FrontendIn a cluster frontends perform the following functions:

• Exchange mail protocol SMTP c other servers

• Organization of SIP-signaling and implementation of PBX-Application (implementation of this function is synchronized between the nodes, and such clusters, we still call the SIP-farm, SIP-farm)

• Protective functions - RBL, error counts and amounts received information from one address black / white lists of IP and DNS-addresses, and so on. D.

• Organization of client server connections (IMAP, POP, HTTP, XIMSS etc.). After the connection is drawn to the frontend to backend has only data

It is also possible the optimization of storage via SSD. Each account in the folder contains files and account.setting account.info. These files used to read each time a user logs on with this account. And the file info is changed every time the metadata changes account (for example, check-SIP-devices). To improve the overall effectiveness of storage, you can save these files separately in the more expensive and effective media (SSD). For one million accounts total size of all these files will be equal to 5-20 Gb.

Features personal cluster configuration

Flexible system configuration allows you to configure the cluster operation of the equipment and software in different ways depending on the task. Our experts will help determine the customer with the choice of the most convenient and suitable option.

Balanced dynamic clusterCommuniGate Pro Cluster can be configured so that each node represents both frontend and as backend. This is called a symmetric configuration.

Tips for setting up a data warehouse

In a clustered domain, all user accounts should be available to all backend. We recommend that you apply for the organization of storage NAS with NFS-protocol.

Since cluster CommuniGate Pro does not practice the lock file in the file system, NFS is for him the most suitable protocol.

Dynamic cluster configuration SIP-farmSIP-Farm - a company CommuniGate Systems technology for clustering VoIP, the time to achieve 99.999% service availability, enhance safety factor, and scalability. And usually a dynamic cluster and supercluster can be configured as SIP-farm (in this case we say that a part of the nodes highlighted in SIP-farm).

Included SIP UDP-packets or TCP-connections are distributed, as usual, through load balancers. The server receives the packet, determines whether he must not be treated in another member SIP-farm (if a response or an ACK for an existing query, or package to a task on a specific server), and if necessary, it forwards.

Packets not addressed to specific nodes, distributed among members of the farm intracluster algorithms - in accordance with the load and the availability of the nodes in the SIP-farm.

Dynamic cluster is considered to be the flagship of all possible configurations of the server CommuniGate Pro. That “use cases”- high service designed for mass use, have always been the basis for the design of the product

note

The most sophisticated tech-nology dynamic cluster and farm SIP requires standard hardware servers, simple load balancers, public file storage such as NFS servers or clustered file systems.

CommuniGate Pro – platform APIs

36

Application Programming InterfaceEach operating system has its own software API (Application Programming Interface). CommuniGate Pro is a platform whose behavior can be controlled at different levels.

From the client’s access to basic communication modules and the development of its own functionality based on standard protocols.

The solution is stable and can withstand heavy loads. Although the input threshold into all CommuniGate API together may seem quite large, they cover most of the challenges facing administrators of communications services. Consider the set of tools available to the CommuniGate Pro server for:

• Automation of administrative tasks

• Processing of letters and phone calls

• Connection of third-party applications and scripts

• Building a HTML-interface

• Building a UC-customers and utilities in various platforms

CLI - a standard way of managing many products. Easy to automate administrative tasks. The format and the full description of the commands can be found in the User’s Guide, we present a few examples.

Poppwd access to server There are several ways to access the CLI. One of the most convenient to get familiar with the commands can be regarded as a module PWD. In the standard configuration, the server just type in the command line OS «telnet server.address 8106» (or «telnet server.address 106», depending on the OS and version). Initially, this unit was simply implementing the change password protocol - poppwd:

$ telnet localhost 8106 Trying 127.0.0.1... Connected to localhost. Escape character is ‘^]’. 200 mymac.ru CommuniGate Pro PWD Server 6.0.5 ready <1.1381912847@mymac.ru> user postmaster 300 please send the PASS pass ******

Application Programming Interface 200 login OK, proceed

newpass ****** 200 Password updated

Access via HTTP

CLI-commands can also be done by sending a simple POST or GET-request with the parameter «command» at server.name:[http port]/CLI/.

Libraries Because of practical problems bare text access is not very convenient, we created a Perl and Java-library for use with CLI. The site also has a special section, which presents examples of CLI-browser solutions for frequently occurring problems. Executing CLI commands is also possible in the protocol XIMSS (team «cliExecute») in the CG / PL program (function ExecuteCLI ()).

Domain Rules with priority> 5 Rules Account Domain Rules with priority <= 5

The order of signal processing:

• Apply server signaling a blank rule «When» (meaning that they are applied at once) Those signals that result in routing got into local accounts, handled the remaining server rules (the «when» is not empty), domain rules and regulations in the accounts as follows:

Server rules with priority> 5 Domain Rules with priority> 5 Rules Account Domain Rules with priority <= 5 Server rules with priority <= 5

Examples of use Limitation of delivery within a domain:

All calls to destinations outside the specific domains are redirected to a given address:

Mail and signaling rules Perhaps the reckoning rules to the API can be called a stretch, but CommuniGate Pro rules apply not only to redirect emails and phone calls between user accounts and mailboxes, but also deliver a letter to a third-party program (eg various filters), is launching CG / PL-programs and even run scripts in the operating system - in short, are widely used for integration by themselves or in conjunction with other API.

Signals in the CommuniGate Pro called special objects that are used in communications «real time» (Real-time). Signal - a unit Real-time communication. Various participants (SIP, XMPP-client, PBX-Application ...) send each other signals for the organization, continuity and status updates dialogues and other actions.

Как работают правила Rules are divided into three levels - server, and domain level account (account). At each of these levels there are separate rules for the signals and for the post. Each rule has a name and a priority signal from the rules there is the condition of «when».

The higher the priority - the sooner, the others under the same conditions, will work normally. Conditions «When» determines at what point work rule - on a second signal processing, or when an error occurs with a specific code («Not Responding», «Busy,» or other errors):

The procedure for handling messages:

• Apply all server rules

• Those letters, which came as a result of the routing in the local accounts are processed domain rules and regulations in the accounting records as follows:

for example

An example of a generalized session for helper-protocol (I – Input program, O - O):

O: * My Helper program started I: 00001 INTF 1 O: 00001 INTF 1 I: 00002 COMMAND parameters O: 00002 OK I: 00003 COMMAND parameters I: 00004 COMMAND parameters O: * processing 00003 will take some time O: 00004 ERROR description O: 00003 OK I: 00005 QUIT O: * processed: 5 requests. Quitting. O: 00005 OK

There INTF team negotiates the protocol version, and QUIT ends the session * - This is an informational message that the server is not responding, but recorded in the log.

The CommuniGate Pro implemented helper protocol, which allows you to use external to the server software for various tasks. Under certain conditions, for example, a post usually starts the filter writing that processes, or in pursuing an external domain authentication, the server starts the helper program.Then begins the standard input to send the team helper protocol and reads answers from the standard output.

As part of this protocol are designed for more specialized:

• Processing of the message body

• External authentication

• Connections banner system

• Adding RADIUS-authentication requests

• Manage load balancing cluster

They all connect to the page Settings-> General-> Helpers WebAdmin interface.

All paths to the executable files are measured from the base directory CommuniGate Pro (directory with the user data).

Processing the message body Handlers letters run postal regulations, such as this:

A detailed description of the commands and other helpers can be found instructions for setting up the system. Helpers of this type are mainly used to connect to CGPro anti-virus and anti-spam engines.

External authentication Helper protocol for external authentication is typically used when:

• Need authentication method is not supported by the server directly

• Some accounts found on the rear of the RA in the other system (eg AD)

• Need complex routing

• Should external management services \ account settings

The rest of the helpers Helper’s banner server systems provide banners for XIMSS and others (e.g., HTTP) clients.RADIUS-helper allows you to add additional authentication process checks for RADIUS-protocol. Helpers load controlled load balancer in a clustered configuration CommuniGate Pro.

String files .data files contain text data (UFT-8) format in CG / PL-vocabulary, these data are used by various server modules to form rows in the interface or as value adjustments.

These files can also form a hierarchy, but at the level of the keys in the dictionary, that is, if any key is not in the file strings.data domain, the server attempts to find it in the file strings.data at the server level, etc. English is the default language for the strings in the interface. If the language of the user (session) is different from English, the key values of language files (french.data, russian.data) replaces the value of strings.data file.

This system allows you to turn in a slightly modified interfaces (files strings.data) Only those keys that have been changed (for example, company name, brand name), rather than a complete set.

Query Processing When a browser connects to a server at the HTTP-report, the server retrieves the host name of the request and looks for a domain with that name. If the domain is found, the server finds the skin selected as the web interface by default for users of this domain. Runs page login.wssp.

Files wssp consist of markup (typically HTML) with some additional elements:

• text, bounded on two sides of a double symbol% (%% element %%)

• structure of this format

WSSP (Web Server-side Pages) - a language for templates of Web-pages.

Each Web skin consists of three types of files:

• Static files - graphics, styles, ...

• WSSP-files

• Language and string files

Along with the distribution CommuniGatePro comes a small set of standard (stock) Web-interface. One ring (Unnamed), remaining a named. These demonstration skins are stored in the Application-server folder (the folder in the operating system, the executable file), so they are replaced when you upgrade the server. Administrators should not change in their skins, display configurations, when you install the update these changes may be lost. Instead, you should use the fact that the skin files form a hierarchy.

The hierarchy of files in the skins Each skin can be a server, domain or standard. When processing requests from the user’s browser usually you need to get the server files with specific names from the skin. Moreover, if the file is not found in the domain of the tabernacle, its looking for the skins in the server with the same name. And if you have not found in the server, you are looking in the default. If the file is still not found, and the current named skin, the file sought in the nameless skins.

Thus, downloading files to your own server ring skin, the server administrator can ensure that the files will be used instead of the standard. That is, such an approach is possible as prodelyvat small changes to the default skin, as well as develop their from scratch.

The main advantage over other CommuniGate Pro system is a server-side language for all modules - calls, mail, calendars. That is, we can take in one program call, play voice menu and DTMF take shape on the basis of the DTMF-mails, SMS, calendar events.

In addition to the PBX it is actively used in the development of web interfaces CommuniGate Pro. If you open the file list even basic web skins (Users-> Interfaces), then there will be 14 files with a few CG / PL-processing program HTTP-requests.

For example

To access the CG / PL-processing program HTTP-request, you need to write it in a text editor, save as .wcgp and load any web skin.

Thereafter, a request to the URL of the form:

http://domain.name:[port]/programFile.wcgp/?Skin=skin_name

runs a program to perform, and

http://domain.name:[port]/auth/programFile.wcgp/?Skin=skin_name

runs the name of the account with the predictions provisional authentication.

http://domain.name:[port]/sys/programFile.wcgp

This query searches for the program only in the server unnamed-skins and launches the user’s behalf postmaster (server administrator).

For example, consider a small script CLI-performing team «listaccounts» and conversion bonding results in JSON-format:

entry sysEntry is

void(executeCLI(«listaccounts mymac.ru»)); accountList = Vars().executeCLIResult;

SetHTTPResponseCode(200); SetHTTPResponseData(ObjectToJSON(accountList));

end entry;

An example of such a document:

<html> <body>

<h1>Welcome on %%server%%.Your login %%ID%%.</h1>

<!--%%IF EXISTS(lastLogin)-->You were visiting last time %%lastLogin%%

<!--%%ENDIF-->

</body> </html>

After processing all of the special design of the server will be replaced by strings or arrays of strings of «environment» - the key values of the .data file into the tabernacle, the domain name or other objects in the server, the values of the settings. All other files are simply given to the client.

Basic demo web interfaces can be considered as an excellent illustration of the possibilities WSSP-pages. But WSSP rather limited in matters of format conversion of data or access the various modules and perform any action on the server. And then it comes to help a more powerful tool.

With such a large amount of functionality on the server side - the voice, instant messaging (including SMS), calendar, contacts, mail, file server at the service provider, there are certain difficulties with the writing of a unified client. It is necessary to choose or develop libraries that implement SIP, set * DAV-protocol, SMTP, IMAP, XMPP. When the load on the analysis of messages and data formats of these protocols lies with the client.

As a solution to these problems, we developed a protocol XIMSS - XML Interface to Messaging, Scheduling and Signaling. All commands of this protocol - simple XML-documents with transparent within the meaning of the attributes. For example, this simple command will redirect (fork) incoming calls on the two users:

C:<callRedirect id=»A018» callLeg=»inp003» > <To>user1@example.com</To><To>user2@example.com</To> </callRedirect> S:<response id=»A018»/>

All data formats (MIME, vCard) come XIMSS-customer in an easy to use form.

Also, the protocol allows for all CLI-commands available on the server - it can be controlled through all kinds of settings, including administrative.For a number of platforms we have developed ready XIMSS-library.

Examples of opportunities XIMSS customers recommend a series of applications Pronto !, a Web version which (HTML5 and Flash), you can try on our stand bestvoip.ru.

For example

ОАО «Сбербанк»

В рамках построения единой корпоративной телефонной сети специали-сты столкнулись со всем спектром проблем разнородной телефонной сети большой корпорации и огромного количества ее филиалов. Для преодоле-ния этих проблем было принято решение о развертывании центрального E-SBC на границе между основной и локальными сетями. К центральному E-SBC предъявлялись достаточно жесткие требования. Контроллер должен обеспечивать высокие показатели надежности, защищенности, пропускной способности, возможность горячего резервирования и геораспределенного развертывания, интеграцию со смежными системами (включая центральный каталог сотрудников для подстановки в телефонную сигнализацию кор-ректно читаемого имени звонящего сотрудника по его короткому номеру и систему внутреннего учета телефонных вызовов). Также E-SBC должен об-ладать протокольной совместимостью с широкой номенклатурой телефон-ных систем (включая Avaya, Cisco, Siemens, AcmePacket, Polycom, Microsoft и др.) и возможностью тиражирования решения на территориальные банки.

По результатам проектных изысканий в качестве платформы центрально-го E-SBC был выбран продукт CommuniGate Pro компании CommuniGate Systems. Действительно, версия шестого продукта представляет собой идеальную платформу для построения комплексного E-SBC корпоратив-ной телефонии.

Проект по развертыванию ЕСКТ с участием CommuniGate Systems был реализован за десять месяцев. На текущий момент весь телефонный тра-фик Центрального аппарата и Московского банка ОАО «Сбербанк России» пропускается через геораспределенный центральный коммутатор на базе платформы CommuniGate Pro.
