Filed:

Dec 21, 2000

Appl. No.:

09/745452

Inventors:

William P. Hann - Round Rock TX, US
Guillermo A. Franco - Austin TX, US
Craig D. Botkin - Cedar Park TX, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L012/54

US Classification:

370413, 711157

Abstract:

An interleaved read/write operation in a data switch determines a read memory of at least two memories that has been accessed during a most recent read operation. A memory controller determines a write memory different from the read memory and accesses a cell buffer list associated with the write memory to determine a buffer to store the cell. The switch writes the cell to the buffer to interleave read/write operations between the read memory and the write memory.

US Classification:

370390, 370432, 3703951

Abstract:

A method for transmitting data to multiple destinations includes storing a data portion in association with a current destination and a next destination. The method also includes (a) transmitting a copy of the data portion to the current destination, (b) updating the current destination to be the next destination and updating the next destination to be a new next destination, and (c) after updating, storing the current destination and the next destination in association with the stored data portion. The method repeats steps (a), (b), and (c) at least one time.

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 12/28

US Classification:

370412, 370417, 370418, 37039541, 37039543

Abstract:

A method for distributing digital subscriber line (xDSL) data traffic includes receiving xDSL traffic at a DSLAM including a plurality of input ports and a plurality of output queues. Each input port includes a plurality of virtual circuits. Each of the plurality of virtual circuits are dynamically assigned to one of the plurality of output queues. The assignment of any particular virtual circuit to one of the plurality of output queues is independent of which of the plurality of input ports the particular virtual circuit is associated with. In accordance with the particular embodiment, the total number of virtual circuits is greater than a total number of output queues.

Abstract:

An method for storing and retrieving data in memory includes receiving the address of a first memory location in the data memory storing a first portion of the data and obtaining, from a location in a link memory specified by the address of the first memory location, a second address of a second memory location in the data memory storing a second portion of the data. The method also includes retrieving the first and second portions of the data in the first and second memory locations in the data memory.
