20090103490 | Forwarding data path optimization in a distributed environment for achieving micro-mobility - A method and apparatus of updating a forwarding plane of a network element in response to receiving a mobility event is described. The network element receives a mobility message indicating a mobile node has coupled to a new access port associated with the network element. The message further indicates that the mobile node moved from an old access port to a new access port. The network element adds an entry in a forwarding table of the old egress engine to redirect a set of packets destined to the mobile node to a new egress engine, where the new egress engine is associated with the new access port. Furthermore, the network element redirects the set of packet from the old egress engine to the new egress engine. | 04-23-2009 |
20090141740 | MULTIPLE PROTOCOL CROSS LAYER CUSTOMIZED QoS PROPAGATION AND MAPPING - Techniques for multiple protocol cross layer customized QoS propagation and mapping are described herein. In one embodiment of the invention, a first QoS code of a packet is determined, the packet having a first encapsulation layer and a second encapsulation layer, the first QoS code being included within the first encapsulation of the packet. From application of a first cross layer QoS map to the first QoS code, determining that the second encapsulation layer of the packet should be used in determining a QoS classification. The reference point to the second encapsulation layer is stored. The QoS classification is determined with use of the reference point. A representation of the QoS classification is stored in a QoS descriptor and the QoS descriptor is used to influence processing of the packet. Other methods and apparatuses are also described. | 06-04-2009 |
