Embodiment Construction

[0014] In the embodiment according to the invention as shown, the incoming data packet arrives at the head processor unit 1 which can read the management information stored in the header of the data packet. The management information in the data packet is transmitted from the originating processor unit 1 to the distribution unit 2 . The data packets are distributed to the input memory ports i (i=1, . . . , N) of the associated parallel connection processor units Pi (i=1, . The input memory port i has the address of the processor unit Pi. Data packets assigned to processor unit Pi may be stored in input memory port i until Pi can process them. However, if this causes input port i to overflow, then no data packets will be supplied to input port i. For data processing, the processor units Pi each have a processor and a local data memory. The local data memory for the processor unit Pi is used eg to store management information when data packets are being processed, and to stor...

Abstract

A unit for distributing and processing data packets has an administration unit for distributing the data packets to parallel-connected processor units. In this case, the processors of adjacent processor units have intermediate connections for interchanging data. The administration unit distributes the data packets in dependence on administration information for the data packets and / or on operating information for the processor units.

Description

technical field [0001] The invention relates to a unit formed from parallel connected processors for distributing and processing data packets. Background technique [0002] When using glass fibers to transmit data packets, data rates greater than 1 billion / s are currently achievable. Such generally high transfer rates have not yet been achieved due to various limitations e.g. from packet routers or distributors (switches). Traditional packet routers are primarily based on software solutions. Sometimes, hardware solutions that frequently use semiconductor modules designed for specific applications are also used. Commonly known as application-specific integrated circuits (ASICs), these can achieve higher data transfer rates than pure software solutions, but with little flexibility. Furthermore, the processing speed of the processor used for the actual data processing is not close to the data rate generated in the data lines. For this reason, a variation is the use of two o...
