DHCPv6 address autoconfiguration for source-routed networks

摘要

In one embodiment, first IP addresses are allocated to a plurality of nodes, respectively, in a computer network, the first IP addresses being routable IP addresses and specifically designated for routing packets in the computer network. At the same time, the plurality of nodes is allowed to submit a second IP address allocation request indicating a requested second IP address. In response to a second IP address allocation request from a particular node of the plurality of nodes, the requested second IP address of the second IP address allocation request is allocated to the particular node. The particular node is then allocated one of the first IP addresses and the requested second IP address. Also, a routing topology for routing packets in the computer network is constructed using only the first IP addresses.

1. A method, comprising:
allocating first Internet Protocol (IP) addresses to a plurality of nodes, respectively, in a computer network, the first IP addresses being routable IP addresses and specifically designated for routing packets in the computer network; allowing the plurality of nodes to submit a second IP address allocation request indicating a requested second IP address, wherein
in response to a second IP address allocation request from a particular node of the plurality of nodes, the requested second IP address of the second IP address allocation request is allocated to the particular node, such that the particular node is allocated one of the first IP addresses and the requested second IP address; constructing a routing topology for routing packets in the computer network using only the first IP addresses; and allocating the first IP addresses so as to enhance a compression ratio of the first IP addresses that are allocated across the plurality of nodes.
