摘要： One embodiment includes, inter alia, methods, apparatus, computer-storage media, mechanisms, and/or means associated with automated transitioning between different communication protocols in a network. In one embodiment, automatic transition routers are automatically discovered along with the knowledge of what non-native protocols need to be transported across a network. Communication pathways are automatically established as needed to transport these non-native protocols. One embodiment is particularly useful in transitioning a network from one protocol to another, such as from Internet Protocol version 4 to version 6.

摘要： A method is provided in one example and includes receiving signaling data associated with a request for a multicast channel, the request includes an Internet protocol version 6 (IPv6) source and an IPv6 group address. The method may also include identifying an Internet protocol version 4 (IPv4) source and an IPv4 group address to be mapped to the IPv6 source and the IPv6 group address. The signaling data can be converted from a first protocol to a second protocol. The converted signaling data can be communicated to a network element. In more particular embodiments, the network element is an IP edge router configured to join the multicast channel and stream data in response to receiving the converted signaling data. The IP edge router can be configured to perform an encapsulation operation to transport IPv6 multicast packets within an IPv4 multicast channel.

摘要： A router is configured for dynamically applying an address prefix value, during execution of a router command, based on retrieving the address prefix value for an address prefix identifier specified in the router command. For example, the router may generate au IP address, for use in executing a router command, based on detecting an address prefix identifier specified in the router command, retrieving a prefix value for the address prefix identifier, and adding the prefix value to an address suffix specified in the router command. Hence, the address prefix identifier in the router command enables global reconfiguration and renumbering of all commands specifying the address prefix identifier, merely by changing the prefix value associated with the address prefix identifier.
摘要翻译：路由器被配置为在执行路由器命令期间基于检索路由器命令中指定的地址前缀标识符的地址前缀值来动态地应用地址前缀值。例如，路由器可以基于检测到路由器命令中指定的地址前缀标识，检索地址前缀标识符的前缀值，并将前缀值添加到地址中，生成用于执行路由器命令的au IP地址路由器命令中指定的后缀。因此，路由器命令中的地址前缀标识符仅通过改变与地址前缀标识符相关联的前缀值，才能对指定地址前缀标识符的所有命令进行全局重新配置和重新编号。

摘要： Techniques for automatically identifying an edge-facing router in a network are provided. In one technique, data is obtained at a first router of a subscriber network. The data may be included in a DHCP message or a NDP RA message. The first router determines, based on the data, whether the first router is a service provider (SP)-facing router, which is a router that is coupled to a SP router and no other router in the subscriber network is logically between the SP-facing router and the SP router. If it is determined that the first router is an SP-facing router, then the first router stores identification data that identifies the first router as an SP-facing router. Otherwise, the first router stores identification data that identifies the first router as a non-SP-facing router.

摘要： IPv6 traffic may be carried through an MPLS IPv4 network without the use of IPv6-over-IPv4 tunneling. This provides great savings in overhead, signaling, and state information storage and also allows for routing through the MPLS IPv4 network to adjust in response to changes in network state. In one embodiment, an edge node of an MPLS IPv4 network resolves a destination IPv6 network of a received IPv6 packet to an MPLS label switched path. The resolution exploits received inter-domain routing information. This information identifies the IPv4 address of an egress node that is usable as a gateway to the destination network. Within the inter-domain routing information, the IPv4 address may be encoded in IPv6 format.
摘要翻译： IPv6流量可以通过MPLS IPv4网络进行，而不需要使用IPv6 over-IPv4隧道。这提供了开销，信令和状态信息存储的巨大节省，还允许通过MPLS IPv4网络进行路由以根据网络状态的变化进行调整。在一个实施例中，MPLS IPv4网络的边缘节点将接收的IPv6分组的目的IPv6网络解析为MPLS标签交换路径。该解决方案利用收到的域间路由信息。该信息标识可用作目的地网络的网关的出口节点的IPv4地址。在域间路由信息中，IPv4地址可以以IPv6格式编码。
