Abstract:
1. A method for controlling packet routing for a mobile node in a network, the network comprising a network domain, the network domain comprising a plurality of forwarding elements configured for being controlled by a control element, the method comprising: computing, for each of the forwarding elements, a route from the forwarding element toward the mobile node, wherein each route is computed using location information associated with the mobile node and routing information associated with the network domain; propagating the computed routes toward the respective forwarding elements of the network domain for configuring the network domain to provide a distributed forwarding plane for a mobility Home Agent (HA); wherein, for each forwarding element, the route is computed in a manner for obviating a requirement that a path to the mobile node include the mobility HA; and wherein, for each forwarding element, the computed route identifies a next-hop node for routing packets intended for the mobile node from the forwarding element toward the mobile node.
