Method Of Multicasting Data Through A Communications Switch
US Patent:
6636511, Oct 21, 2003
Filed:
Nov 21, 2000
Appl. No.:
09/717472
Inventors:
Subhash C. Roy - Lexington MA
Michael M. Renault - Medway MA

Assignee:
Transwitch Corporation - Shelton CT
International Classification:
H04L 1228
US Classification:
370390, 370388, 370401
Abstract:
A network switch includes at least one port processor and at least one switch element. The port processor has an SONET OC-x interface (for TDM traffic), a UTOPIA interface (for ATM and packet traffic), and an interface to the switch element. In one embodiment, the port processor has a total I/O bandwidth equivalent to an OC-48, and the switch element has 12Ã12 ports for a total bandwidth of 30 Gbps. A typical switch includes multiple port processors and switch elements. A data frame of 9 rows by 1700 slots is used to transport ATM, TDM, and Packet data from a port processor through one or more switch elements to the same or another port processor. Each frame is transmitted in 125 microseconds; each row in 13. 89 microseconds. Each slot includes a 4-bit tag plus a 4-byte payload.
