Agenda

• TCP/IP

• Broadband connectivity

• Web technology products

3April 8, 2006

Don’t let the name mislead you

There are three forms of TCP

• NonStop TCP/IPv6 S- & NS-series

– a.k.a. IPv6

• Parallel Library TCP/IP S-series only

– a.k.a. TCP/IP/PL)

• Conventional TCP/IP S- & NS-series

4April 8, 2006

• Inherited from K-series

• A Mature product

• Can have multiple instances in CPUs

Now ported to Itanium-based platform

• For X.25, ATM, Token Ring support

• Protocols not available with TCP/IP/PL or NonStop TCP/IPv6

Conventional TCP/IP – the old guy

5April 8, 2006

• New architecture - TCP stack in every processor • Reduces application “hops”

• intra-processor

• inter-processor

• Co-exists with Conventional TCP/IP

• Requires NSK release - G06.10 (or later)

• SWAN support over TCP/IP/PL

• Mature product

• Product no longer ships (year end 2005)

• Still supported; Now for S-series only

• Not available on Itanium-based platform

Parallel Library TCP/IP (TCP/IP/PL)

6April 8, 2006

• Released June 2003 (G06.20)

• Supports both IPv4 (older, common usage) and IPv6 standards

• Individually (IPv4 only, or IPv6 only)

• Concurrently (Dual stack; operating both)

• Same software architecture as supported by Parallel Library TCP/IP

• Solid product• Strategic stack going forward

• Aligned with HP corporate strategy

NonStop TCP/IPv6 (1)

S-series & NS-series

7April 8, 2006

•IPv4 mode – Replaces Parallel Library TCP/IP

– Same features - no regression

� Same APIs, no application changes, recompilation/relinking

� Same configuration script

•IPv6-enhanced features

� IPv4 and IPv6 filtering – can coexistence on same adapter

� TCP/IP middleware enhanced to support IPv6 addressing (except SNMP, NFS – IPv4 and Dual mode)

� Expand support

•Runs concurrently with Conventional TCP/IP, NOT with Parallel Library TCP/IP

NonStop TCP/IPv6 (2)

Everyone runs in IPv4 mode first !

It takes just a few days to convert.

8April 8, 2006

• IPv6 was designed to make transition from IPv4 easy

– But most customers do not need IPv6 addressing yet

– However, you can:

• Start transitioning routers before hosts

• Start transitioning hosts before routers

• Transition routers and hosts at the same time

• Specific site can transition before its ISPs have transitioned

• ISPs can transition before specific sites have transitioned

– It depends on your overall network and the level of the project that you want to take on

Transitioning from IPv4 to IPv6

9April 8, 2006

IPv6 Addressing

• IPv6 uses an increased number of bits for addresses

• You can address every device on earth (and then some)

• 340 undecillion addresses (340 followed by 36 zeros)

• 665,570,793,348,866,943,898,599 addresses per square meter of the surface of the planet Earth

• That’s 24 digits!

• Are you going to get involved in lots of devices – cell phones, printers, PDAs, ATMs, etc.

• IPv6 has other manageability advantages

10April 8, 2006

• Dual stack nodes have both IPv4 and IPv6 address stored in Name Service server

• The product provides for tunneling

– E.g., IPv4 packets within IPv6 packets

• You may have some applications running both IPv4 and IPv6

• You may have multiple applications in a system

– Some running IPv4; some running IPv6

The product supports Dual Stacks

12April 8, 2006

• IPv6-unaware – can communicate with IPv4 only nodes

• IPv6-aware – can communicate with nodes that do not have IPv4 addresses

– Application can handle the larger IPv6 address

– This may be transparent to application if API hides content and format of actual address

• IPv6-enabled

– IPv6-aware

– Capable of taking advantage of specific IPv6 feature (e.g., Flow Labels)

– Can operate over IPv4 (degraded mode)

• IPv6-required – requires some IPv6 specific feature and cannot operate over IPv4

Applications categories

13April 8, 2006

• Even on a node upgraded to IPv6, the use of IPv6 is dependent on the application

– May not use an API that asks Name Service for IPv6 address

– Use of API requires changes to an application

– If API does not support IPv6 addresses

• For that application the node will send-receive IPv4 packets just like an IPv4 node

• IPv6 application deployment

– No application change; run in IPv4 mode only

– Enhance with Dual Stack configuration later; use IPv6 API and addressing

IPv6 Interaction with Applications

14April 8, 2006

•Performance

– At par with Parallel Library TCP/IP

• Measured in IPv4 mode

• No information on IPv6 comparison yet

– Performance report available upon request

Why Logical Network Partitioning ?

• Obtain the requested application isolation• Resolve a configuration limitation

• Segregate traffic from selected clients to specific applications

• Improve application access protection

• In Conventional TCP/IP: by running multiple copies of stack

• With LNP Multiple Partitions• Dedicated set of unique IP addresses

• No communications between partitions

• One TCP/IP stack only; multiple instances in processors

• One point of control (e.g., OpenView)

• Gain the performance benefits of the parallel library software architecture (vs. Conventional TCP/IP)

18April 8, 2006

TCP/IPv6 Configurable Retransmission Timers

•Provide the ability to tune the retransmission variables on an individual TCP socket basis by an application

– Minimum TCP retransmission timeout - minimum time allowed for a TCP retransmission timer.

– Maximum TCP retransmission timeout - maximum time allowed for a TCP retransmission timer.

– Maximum TCP retransmission count - maximum number of continuous retransmissions prior to dropping a TCP connection.

– Total TCP retransmission duration - maximum continuous time spent retransmitting without receiving an acknowledgment from the other end point.

•Allow the default TCP retransmission timer variables that apply to all TCP sockets to be altered unless overridden by an application

26April 8, 2006

Steps to Web-service-enable a Pathway application

1. Look at what functions within the target application can be/need to be made into a service accessible from the web

2. Determine how you call them programmatically now

Use the application’s DDL to provide info to the SOAP server; no code change necessary

Set up iTP WebServer and the SOAP server using the product’s Admin GUI

3. Provide the WSDL to the SOAP Client (e.g., browser)

Test the service

Modify the service process/interaction as necessary

4. Deploy in production

27April 8, 2006

Conclusion

• TCP and Ethernet are the primary networking vehicles today

– Higher speed bandwidth at lower cost

• SWAN and AWAN continue to serve dial-up and leased line applications

• Web services usage is growing gradually

• Development/improvement continues

– There is a new approach coming for TCP connectivity

– Mid 2007 timeframe
