A packet gateway (PGW) receives a plurality of IP packet fragments from a network. The IP packet fragments comprise a head fragment and one or more trailing fragments, and are associated with a first IP packet. As the fragments are received, a controller at the PGW classifies the fragments. The controller applies a same selected service treatment to the head fragment and to each of the trailing fragments based on the classification of the head fragment. The PGW then sends each treated packet fragment to an end user device.

A method implementing dynamic next-hop routing at a network device is disclosed. The network device contains a routing information base (RIB) and a forwarding information base (FIB). The method starts with receiving a request to create a dynamic next-hop type using a next-hop schema. The dynamic next-hop type is for a prefix associated with an application. The next-hop schema includes a set of functions and a set of fields associated with the set of functions. The dynamic next-hop type is created using the next-hop schema at the RIB, where the set of fields associated with the set of functions of the dynamic next-hop type is processed. The created dynamic next-hop type is then downloaded to the FIB, where the set of functions of the dynamic next-hop type is processed. Afterward, an identifier associated with the dynamic next-hop type for the prefix associated with the application is returned.

Transferring a mobile node from one ASN-GW (anchor access service network gateway) to another ASN-GW is referred to as a hand-over. To facilitate transfer of data for the hand-over, a GRE (generic routing encapsulation) tunnel is established between the two ASN-GWs. Traffic through the GRE tunnel arriving at a line card of an ASN-GW is redirected from the arrival line card to the one line card that contains information for the mobile node. The redirection is based on traversal of one or more tables on the line cards. These tables are indexed according to GRE keys corresponding to the mobile nodes. Therefore, the appropriate line card for the traffic can be identified quickly and efficiently using a distributed forwarding plane with minimal provisioning overhead, resulting in lower latency during the hand-over.
