Abstract
Identity information is decoupled from reachability information in packets transferred between hosts of a computer network by replacing forwarding information within said packets with an identifier having a format of the forwarding information, and applying forwarding labels, derived from the identifiers, which are then used in lieu of the forwarding information for conveying the packets within the network. During such conveyance, the packets are treated according to one or more policies prescribed on a basis of the identifier, which may be an IPv6 address. The forwarding labels may be MPLS labels.
