Abstract: A policing technique for a telecommunications traffic of variable length packets is described. The technique uses a plurality of police engines, grouped in pairs. A selection module selects a police engine pair to process a packet. Each police engine contains a conformance unit, credit unit and a debit unit, in which the credit update of one police engine influences the credit update of the other police engine in the pair. The technique also uses a combinatorial function to decide on a category of a processed packet and which police engines to update their debit units.

Abstract: An instruction memory shared by a number of processing units has a plurality of individually accessible sections. A software program in the instruction memory is distributed among the memory sections. Sequential parts of the software program are in sequential sections. The software program may have a common portion which is repeated in each of the memory sections. Arbiter logic may control which of the processing units accesses which of the memory sections in each memory access cycle.

Abstract: The method applies to a telecommunication network having IP packet-supporting capabilities when said network includes a load distribution processing function which is either centralized or distributed and by means of which a load distribution function is applied to sets of paths between network nodes and/or sets of links (Lk1, Lkp) of network trunks (12).

Abstract: A high speed programmable ER computational engine that is based on a micro-programmed control unit and a register intensive pipelined datapath that removes the need for having an instruction set interpreter includes a data path unit operably coupled to directly receive datapath control words from a control unit. The control unit includes memory and an address unit, where the memory stores the data path control words, which relate to a computational algorithm. The address unit receives input (e.g., begin an ER calculation) from an external source, where the input causes at least some of the data path control words to be retrieved from the memory. The data path unit includes a pair of register files, a plurality of floating point units, and data flow coupling. The pair of register files operate in a double buffering manner such that one of the register files is receiving parameters (e.g., data rate information of a connection) for subsequent computation while the other is used for a current computation.
