WiChorus SmartCore Platforms

WiChorus network elements support robust embedded

management features, including industry-standard com-

mand-line interface (ClI), SNMP and BulkStats for efficient

retrieval of information. Integration with 3rd party NMS or

OSS systems is facilitated through direct interfaces to the

network elements or northbound CORBA or SNMP interfaces

from the EMS. The WiChorus solution enables carriers to

automate repetitive tasks, rapidly respond to conditions in

the network, and proactively manage subscribers and services.

Architecture

The WiChorus EMS is a robust client/server software sys-

tem that is designed to support large scale networks. The

modular architecture enables the distribution of functional-

ity across one or more servers to provide optimal perfor-

mance and redundancy. For example, EMS front-end pro-

cessing can be offloaded to a separate server to support

a very large number of clients. Additionally, the mediation

function, which aggregates information from network ele-

ments, can be distributed to regional servers, to streamline

processing of overall network information.

The EMS supports multiple concurrent users leveraging

Java client software supporting a rich graphical user inter-

face. Communication with network elements is through

industry standard SNMP, along with BulkStats operations

to efficiently gather real time statistics and monitoring

information across a range of network elements and sub-

scribers. WiChorus accommodates interfaces to 3rd party

NMS or OSS platforms through a northbound CORBA inter-

face, along with SNMP.

The EMS server can be deployed in combination with an

Oracle database providing further flexibility in designing

robust management solutions. . A primary and secondary

EMS server can be simultaneously linked to the database

server to ensure continuous operation should one of the

EMS systems fail. The Oracle database server itself can

also be deployed in a variety of redundant configurations

to ensure maximum availability.

Intuitive User Interface

The WiChorus EMS provides a rich user interface with intui-

tive navigation to help streamline operational costs. The

system supports multiple views of the network, including a

convenient tree-based view along with a graphical network

view showing the overall network topology. With a compre-

hensive view of the network, service providers can quickly

navigate to find information they need and drill down for

additional detail as required. The EMS maintains a com-

prehensive, real-time chassis view of each node displaying

lED state, high availability state and CPU utilization. This

enables users to view equipment in the network as if they

were physically right next to the device.

The WiChorus EMS leverages unique hierarchical table

views with search and filtering capabilities that simplify

navigation of large amounts of information, such as sub-

scriber stations. These advanced tabular views enable

operators to sift through several levels of hierarchy from

a single window, enabling them to quickly zero-in on the

information they are looking for without cumbersome click-

throughs. Operators are also kept abreast of the most

critical network information on the top-level screen through

a series of summary panes that track overall fault and per-

formance activity. Such summary views ensure key issues

are elevated to receive the attention they deserve without

flooding users with excessive data.

Network Configuration

The WiChorus EMS provides user-friendly screens for

configuring all WiChorus elements in the network.

Configuration information is stored within the EMS data-

base, as well as being pushed onto the network elements.

The solution provides a built-in backup of each node’s

configuration for purposes of restoration and recovery

should a network failure occur. Repetitive configuration

can be efficiently handled through the WiChorus system,

as one node’s configuration can be used to help configure

other nodes in the network when only a few pieces of infor-

mation need to be changed. In addition to node specific

configuration, the WiChorus EMS has user friendly screens

designed to accommodate configuration of network-wide

policies, such as content management, spectral manage-

ment or traffic management.

Subscriber Management

Playing a key role in subscriber management, the

WiChorus SmartCore platforms provide a wealth of infor-

mation regarding individual subscribers and their associated

traffic. The WiChorus EMS captures this information to

provide service providers a central view of key subscriber

attributes, such as addressing assignments, QoS profiles,

wireless state (active/idle), location and traffic statistics.

In addition, service providers can configure policies, such

as address assignment, traffic management or security on

a per subscriber basis.

Performance Management

The WiChorus EMS provides graphical monitoring tools for

displaying a wide range of real time statistics collected

from WiChorus nodes and subscriber stations. Service

providers can customize these charts to ensure they meet

the needs of their day-to-day operation. In addition, intui-

tive Key Performance Indicator (KPI) dashboards provide a

convenient tool for real-time monitoring of critical metrics,

such as CPU utilization, network size, and traffic metrics.

These powerful tools enable service providers to manage

and deploy large scale networks, while maintaining visibil-

ity of overall performance of the network at various levels.

Administration

The WiChorus EMS provides service providers a robust

solution for managing administrative access to the system.

Individual user accounts can be created with varying levels

of access, and the system provides extensive tracking and

logging for each user. These capabilities ensure flexibility

and accountability in managing user authentication.

The WiChorus EMS also supports comprehensive image

management, ensuring minimal disruption for service pro-

viders as they upgrade their networks. With dual image

support on all WiChorus network elements, new software

can be downloaded at any time while activation of the new

image can be custom configured by the user. This enables

proactive scheduling of network upgrades with minimal

disruption to the operational network. Any failure of the

image within the node will cause the system to revert to

the original image, to ensure stability in the network.

Fault Management

The WiChorus EMS provides real time event reporting,

intelligent response mechanisms, and intuitive visual

indicators allowing for swift resolution of network issues.

Alarms can be generated based on a single event or based

on a collection of related events. They can be assigned dif-

ferent severity levels, and can trigger unique actions based

on the defined severity level, such as initiating an email,

page or executing a command. Alarms can be filtered

and sorted by source, criticality, or time/date. Intuitive

visual indicators at the highest-level view through the most

detailed product view enable service providers to quickly

identify and isolate faults in the network.

Policy Management & Network Intelligence:

leveraging extensive DPI capabilities in the SmartCore

platforms, the WiChorus EMS allows operators to eas-

ily analyze and manage their network based on content.

Policies can be defined to identify specific applications,

including Peer-to-Peer traffic, and perform statistics cap-

ture, traffic policing, QoS prioritization or filtering based

on this content. Policies can be configured with extensive

granularity and distributed and enforced across the net-

work. The policy management and network intelligence

features of the EMS simplify network-wide monitoring and

enforcement of internet traffic policies.
