    abstract =  {This specification describes identifier-locator addressing (ILA) in IPv6 for network virtualization. Identifier-locator addressing differentiates between location and identity of a network node. Part of an address expresses the immutable identity of the node, and another part indicates the location of the node which can be dynamic. Identifier-locator addressing can be used to efficiently implement overlay networks for network virtualization},
