Abstract: Network nodes acquire bandwidth in contention-based networks for handling video traffic. A request to reserve a channel for transmission of a payload is sent prior to a network node receiving the payload. The payload is a burst of video data that is generated periodically. A network node determines a time period for reserving the channel. The network node determines when to initiate contending for the channel and the time period for transmitting the payload to another network node. A network node determines when a payload is expected to arrive and monitors its back off time period at least a time period prior to receiving a payload. The network node also monitors transmission of the payload and adjusts when to initiate contending for the channel.

Abstract: A method is disclosed for performing message payload processing functions in a network element on behalf of an application. According to one aspect, a network element intercepts data packets comprising network layer or transport layer headers having an address of a destination which destination differs from the network element. The network element determines whether information contained in layer 2-4 headers of the data packet satisfies specified criteria. If the information satisfies the specified criteria, the network element directs the data packets to a blade of the network element that performs processing based on an application layer message at least partially contained in the data packets. If the information does not satisfy the specified criteria, the network element forwards the data packets towards the destination without sending them to the blade.
