CONCENTRATOR-BASED GROWABLE PACKET SWITCH |
摘要 |
An mxn (m > n) output Packet Switch Unit is implemented by using an nxn Packet Switch Module and an m:n Concentrator. The arriving packet cells are supplied from the m Concentrator inputs to the n Concentrator outputs in a "first-in first-out" (FIFO) sequence. The Concentrator provides for buffering of arriving packet cells on the m Concentrator inputs in excess of available packet cell positions in the n Concentrator outputs until they can be supplied to a Concentrator output in the FIFO sequence. In turn, packet cells from the n Concentrator outputs are supplied to n inputs of the Packet Switch Module which supplies them to appropriate output destinations associated with the n outputs of the Packet Switch Module. A plurality of the Concentrator-Based output Packet Switch Units is readily employed to implement any "larger" Packet Switch architecture.
