IntroductionIntroduction
Who is Ixia?Ixia is a leading provider of performance test systems for IP-based infrastructure and services.
What is our vision?Voice, Video and Data communications are rapidly moving to an IP infrastructure. To achieve“utility grade” quality, this infrastructure must be thoroughly tested. It is Ixia’s vision to
provide the best performance test systems in the industry.

Key Areas for TestingKey Areas for Testing
Dual Stack Routers will be heavily used to support:– IP4 and IPv6 Packets forwarding– Tunneling– Address and protocol translation– New routing protocols – OSPFv3, ISISv6, RIPng, BGP4+, MLD
It is critical to make sure the DS Router is able to:– Interoperate with other equipment (conformance test)– Comply with various IPv6 standards (conformance test)– Forward IPv4/IPv6 packets (forwarding test)– Perform reliably well under heavy loading (performance test)– Deliver end to end application with acceptable performance

IPv6 Conformance TestIPv6 Conformance Test
Carefully review IPv6 standards line by line to create a library of automated test cases – IPv6 Conformance Test SuiteThoroughly verify every single feature defined by RFCConduct Conformance Test to assess of interoperabilityFind bugs during design cycle, not at customer site!!Provide baseline for regression testHelp service providers and network operators identify interoperability issuesTest tool needed – IPv6 Conformance Test Suites

IPv6 Test SuitesIPv6 Test Suites
Important RFCs customers wish to test– IPv6 (RFC 2460)– Transmission of IPv6 Packets over Ethernet Networks (RFC 2464)– IPv6 over PPP (RFC 2474)– ICMPv6 (RFC 2463)– Stateless Address Autoconfiguration (RFC 2462)– Path MTU Discovery (RFC 1981)– Neighbor Discovery Protocol (RFC 2461)– Multicast Listener Discovery (RFC 2710)– Tunneling (RFC 2529, RFC 2893, and RFC 3056)– A typical test coverage can be as many as 572 test cases!!
IPv4 and Routing Test Suites(IPv6 & IPv4)– IPv4, IS-ISv6&IS-IS, OSPFv3/v2, BGP4/BGP4+, RIP/RIPng, IGMP/MLD,
PIM-SM, TCP/IPv6

IPv6 - Performance and ScalabilityIPv6 - Performance and Scalability
Forwarding– Throughput, latency, packet loss– Isolated, normal, and stressful conditions
• No routing protocols enabled• Typical network topology• Scaling to a large network topology
– IPv6/IPv4 Tunneling and protocol conversion (dual stack devices)
Control plane (OSPFv3, RIPng, ISISv6, BGP4+)– Rate of establishing, updating, and tearing down sessions and routes– Capacity of sessions and routes over one or many ports– Sessions and routes when other protocols are enabled
Multicast support– Number of multicast groups– Join/leave latency
Application response time and goodput– End user experience counts. Need stateful traffic simulation.

SummarySummary
IPv6 Infrastructure brings new performance items to be tested– Tunneling– Translation– New Routing Protocols
Conformance test is critical to assess interoperability between vendor’s IPv6 designPerformance and Functional tests are required to verify the new IPv6 data plane of DS RoutersApplication test is required to ensure the improved user experience
