Abstract: A method and apparatus in a group manager of a central service node, for enabling services or media in a communication network. A monitoring unit detects and monitors activities and conditions of communication entities in the network. A context collecting unit collects individual context data relating to a plurality of monitored entities in order to survey the current situation of each respective entity. A group defining unit then defines a group of correlated entities that are found to be correlated or similar with respect to at least some feature or characteristics based on the collected individual context data, by selecting context parameters of relevance to the group and using one or more membership conditions determined for the group. If the monitored entities have changed their status in a predetermined way that affects the group, the group defining unit will update the group.

Abstract: Disclosed herein is a route optimization that allows packets flowing between a mobile node (MN) and a correspondent node (CN) to bypass local mobility anchors (LMAs), thereby improving flow efficiency and/or reducing network traffic. Specifically, the MN's mobile access gateway (MAG) and the CN's MAG may participate in a proxy binding update (PBU)/proxy binding acknowledgement (PBA) exchange with each other to establish the MN's and CN's state in the opposing MAG. After doing so, the two MAGs may send MN-CN packets directly to each other, e.g. without sending such packets to the LMAs. In one embodiment, the route optimization is applied to a situation where the MN's MAG and the CN's MAG are associated with the same LMA. In another embodiment, the route optimization is applied to a situation where the MN's MAG and the CN's MAG are associated with different LMAs.

Abstract: A network switch is comprised of a control processor and one or more line cards. The control processor includes functionality to register interest with a hypervisor, operating in conjunction with a network host connected to the switch, in data object attributes maintained on the network host by the hypervisor. The hypervisor associated with the network host sends changes in the host attributes to the switch which the switch maintains in a listing of attributes. The switch traps and copies particular packets to the switch control processor where a provisioning function operates on the attribute information in the list with source information included in the packet header in order to configure a forwarding table on the line card.
