摘要:
Network elements provide application-level QoS for application-layer messages processed therein. An application based message is examined upon IP reassembly thereof. Information is accessed about a sender of the message. A credential is assigned to the sender based on the sender information and/or a status validated for a device that sends said message. The message is dynamically prioritized in relation to other network traffic to provide application QoS based on the sender credential and/or the device status. The message priority is changeable on the fly according to the dynamically variable information. Sender information relates to a role or authority level associated therewith and is dynamically variable with respect to time, situation and/or circumstance. Thus, OSI Layer 5, 6, or 7 application message role/status based attributes determine how packets are marked with Layer 2, 3 or 4 QoS values, integrating application-level concepts of order and priority into network-layer QoS mechanisms.

A data processing apparatus comprises instructions to perform sending and receiving one or more messages conforming to a network routing protocol, such as Open Shortest Path First (OSPF); obtaining one or more information elements that specify one or more capabilities of the apparatus; creating a particular routing protocol message comprising an opaque advertisement that includes the one or more information elements; and sending the particular message on one of the network interfaces. For example, a router or switch that implements a network routing protocol can use OSPF Opaque Link State Advertisements to advertise and discover services and capabilities of other routers or switches.

In one embodiment, an apparatus comprises logic encoded in one or more tangible media for enhancing transmission reliability of monitored data. The logic is operable to receive a plurality of segments for transmission over a TCP connection to a network node, where the TCP connection is associated with a transmit queue and a retransmit queue. The logic is also operable to detect a transmission anomaly on the TCP connection to the network node, and in response to detecting the transmission anomaly, is operable to perform any one of: store segments into a persistent buffer prior to transferring the segments into the transmit queue; copy segments from the retransmit queue into the persistent buffer, where the segments have been transmitted but not yet acknowledged by the network node; and copy segments from the transmit queue into the persistent buffer, where the segments have not yet been transmitted to the network node.

Methods and apparatus for performing proxy registration on behalf of a node with a Home Agent supporting Mobile IP are disclosed. A first registration request is composed on behalf of the node and transmitted to the Home Agent via a first Local Mobility Anchor, wherein the first Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with the first Local Mobility Anchor. When the node moves within a region or between regions, the node is re-registered. Specifically, a second registration request is composed and transmitted to the first Local Mobility Anchor when the node moves within the region associated with the first Local Mobility Anchor. When the node moves into a second region associated with a second Local Mobility Anchor and outside the first region associated with the first Local Mobility Anchor, a second registration request is composed and transmitted to the Home Agent via the second Local Mobility Anchor, wherein the second Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with second first Local Mobility Anchor.

Methods and apparatus for dynamically generating authentication keys are disclosed. Specifically, a Mobile-Foreign authentication key is separately generated by both the Mobile Node and Foreign Agent. Similarly, a Foreign-Home authentication key is separately generated by the Foreign Agent and the Home Agent. In accordance with one embodiment, generation of the Mobile-Foreign authentication key and Foreign-Home authentication key are accomplished via the Diffie-Hellman key generation scheme.

Methods and apparatuses for obtaining home agent assignment. The invention uses a DNS query to signal a request for dynamic home agent assignment. The DNS query will cause a content routing device to be notified that home agent assignment is being requested. The content routing device can then use predetermined metrics to select a home agent. A DNS response will then be sent back to the device that initiated the DNS query containing the IP address of the selected home agent.
