1 Networking Technology Update NonStop TCP/IPv6 and LAN/WAN Connectivity Plus Web technology Wil Marshman Product Manager Networking 2003 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice

2 Agenda TCP/IP Broadband connectivity Web technology products 2

3 There are three forms of TCP NonStop TCP/IPv6 a.k.a. IPv6 S- & NS-series Don t let the name mislead you Parallel Library TCP/IP S-series only a.k.a. TCP/IP/PL) Conventional TCP/IP S- & NS-series 3

4 Conventional TCP/IP the old guy Inherited from K-series A Mature product Can have multiple instances in CPUs App 1 App 1 App 2 TCP TCP Ethernet Controller Token Ring Controller Now ported to Itanium-based platform For X.25, ATM, Token Ring support Protocols not available with TCP/IP/PL or NonStop TCP/IPv6 4

5 Parallel Library TCP/IP (TCP/IP/PL) 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 5

6 NonStop TCP/IPv6 (1) S-series & NS-series 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 6

7 NonStop TCP/IPv6 (2) 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 Everyone runs in IPv4 mode first! It takes just a few days to convert. Runs concurrently with Conventional TCP/IP, NOT with Parallel Library TCP/IP 7

8 Transitioning from IPv4 to IPv6 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 8

9 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 9

10 The product supports Dual Stacks 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 10

11 Transition Mechanism Dual stack Web Application NonStop System TCP, UDP Dual Stack IPv4 IPv6 G4SA v4/v6 filters Gigabit Ethernet LAN v4/v6 Router Dual Stack IPv4 Backbone Dual Stack v4/v6 Router 11

12 Applications categories 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 12

13 IPv6 Interaction with Applications 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 13

14 IPv6 Performance Performance At par with Parallel Library TCP/IP Measured in IPv4 mode No information on IPv6 comparison yet Performance report available upon request your request to 14

15 A special feature of TCP Logical Network Partitioning (before) Hospital n Hospital 1 CPU0 Corporate CPUn Patient care Administration HQ Applications NonStop TCP/IPv6 NonStop TCP/IPv6 LAN01 Servernet LAN02 LAN02 Doctor/Nurse Admin Network HQ Network 15

16 Logical Network Partitioning (after) Hospital 1 Hospital n CPU 0 Patient care Administration NonStop TCP/IPv6 Corporate CPU n HQ Application NonStop TCP/IPv6 Servernet LAN01 LAN02 LAN02 Doctor Nurse Admin Network Subnetworks HQ Network 16

17 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) 17

18 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 18

26 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 26

27 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 27
