Systems and related methods are described for handling one or more resource requests. A protocol engine receives a resource request in accordance with a prescribed protocol, and a classification engine determines a desired class of service for the request. An analysis engine optionally analyzes the request, and, responsive thereto, determines a desired sub-class of service for the request. A policy engine then allocates a resource to the request responsive to one or both of the desired class of service, and the desired sub-class of service.

Switching system

A packet reassembly system includes a buffer for storing information elements included in one or more incoming packets, a memory for storing validity indicators corresponding to the information elements, a first logic circuit capable of setting the validity indicators based on the information elements stored in the buffer, and a second logic circuit capable of determining the contiguity of the information elements stored in the buffer based on the settings of the validity indicators.

Method and system for reassembling and parsing packets in a network environment

A method and a system are provided for managing fixed size memory blocks in a graphic imaging system. A system memory includes at least one queue containing a linked list of fixed size memory blocks and a page pool of variable size memory blocks. A system memory manager allocates memory blocks from the system memory in response to requests. Upon a request for a memory block of a particular fixed size, the system memory manager allocates a memory block of the fixed size from a queue containing memory blocks of the fixed size if the queue has memory blocks available. If the queue does not have memory blocks available, the system memory manager creates an extension to the queue containing memory blocks of the fixed size. The extension is created from a page pool. The extension is linked to the queue, and a memory block of the fixed size is then allocated from the queue. If the page pool does not contain adequate memory to create an extension, the portion of the page which has been reduced to display list entries is rendered, and all of the allocated memory blocks are deallocated. Then, a memory block of the fixed size is allocated from the queue.
