IPv6 support
WAS version introduces selective support for Internet Protocol V6 (IPv6). IPv6 is the next evolution in Internet Protocol beyond the IPv4 standard currently in use in most networks today. IPv6 client workload now can be distributed to back end appservers, and proxy server support is extended to new IPv6 clients and servers.
The key IPv6 enhancement is the expansion of the IP address space from 32 bits to 128 bits, enabling virtually unlimited IP addresses. This addressing capability, along with new functions enabling end-to-end security, improved mobility support, simplified address configuration and management, make IPv6 a critical component in the evolution of e-business and the next generation Internet.
The new IPv6 network support extends Load Balancer to IPv6 clients, enabling their workload to be distributed to back end WebSphere appservers for increased flexibility. With proxy server support for IPv6 clients and upstream server connections, you get added network reach and flexibility. For details, see the Edge Component documentation.
IPv6 addresses are supported in JMS connection factories, but require square brackets to distinguish the IPv6 address from the rest of the providerEndpoints string. This is because the colon separator ( : ) used by the providerEndpoints string is also used as the separator in IPv6 network addresses. The standard format for provider endpoints is host:port:chain, and an IPv6 address might appear as follows:
2002:914:fc12:179:9:20:141:42Therefore, an IPv6 provider endpoint setting might be written as:2002:914:fc12:179:9:20:141:42:7276:BootstrapBasicMessagingAn IPv6 address can be of variable length; therefore, it is impossible to know where the IPv6 address ends and the port begins. The solution is to surround the IPv6 address with square brackets, as described in RFC2732 on the Internet Engineering Task Force Web site (http://www.ietf.org). For example, the previous providerEndpoints string becomes:
[2002:914:fc12:179:9:20:141:42]:7276:BootstrapBasicMessagingIPv6 is supported for Tivoli Access Manager, V6.0. IPv6 was not supported on Tivoli Access Manager V5.1 or previous versions.
