Abstract: A method of parsing frame headers for routing data frames within a computer network is disclosed. In accordance with the method and system of the present invention, a data frame is first received from a computer network. A frame header of the data frame is then parsed into multiple test units of identical lengths. A test vector is subsequently assigned to each of the test units, wherein each test vector includes a reference pattern field and an action code pointer field. A number of test blocks are constructed by inserting each of the test vectors into a corresponding slot of various test blocks. Finally, a search tree is constructed by utilizing these various test blocks, and each test block is associated with each other test block via the test vectors contained within.

Abstract: A data processing system includes a server which has a task scheduler for receiving task requests for access, and granting access to system resources based upon a multidimensional scheduling technique wherein groups of tasks are assigned a priority level within a priority scheme, and within each group round robin scheduling assures each task will have access to system resources in turn and a dynamically programmable technique for responding to requests from time-dependent isochronous requests for system resources.
