Filed:

Dec 2, 1998

Appl. No.:

09/204658

Inventors:

Gregory L. DeJager - San Jose CA
James R. Rivers - Saratoga CA
David H. Yen - Palo Alto CA
Stewart Findlater - Mountain View CA
Scott A. Emery - Saratoga CA

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 1228

US Classification:

370389, 370401, 370412, 370418, 709103, 709104, 709105

Abstract:

Provided are methods, apparatuses and systems for balancing the load of data transmissions through a port aggregation. The methods and apparatuses of the present invention allocate port assignments based on load, that is, the amount of data being forwarded through each port in the group. The load balancing of the present invention is preferably dynamic, that is, packets from a given stream may be forwarded on different ports depending upon each ports current utilization. When a new port is selected to transmit a particular packet stream, it is done so that the packets cannot be forwarded out of order. This is preferably accomplished by ensuring passage of a period of time sufficient to allow all packets of a given stream to be forwarded by a port before a different port is allocated to transmit packets of the same stream. The invention may be used in a variety of different network environments and speeds, including 10Base-T, 100Base-T, and Gigabit Ethernet, and other network environments.

International Classification:

G06F 1202

US Classification:

711170, 711171, 711172

Abstract:

Data is stored in a memory in a manner which eliminates dead time which occurs when the number of words in a page which are read-out are insufficient to provide enough time for simultaneously opening the next page. If the length of a frame being stored in memory is not an exact integral multiple of words in a page, a penultimate (or earlier) page is written with fewer words than the page can hold. This allows additional words to be placed into the last page, sufficient to provide every page used for storing a frame at least a number of words equal to the number of clock cycles needed for opening a next page.

Abstract:

The load balancing of the present invention is preferably dynamic, that is, packets from a given stream may be forwarded on different ports depending upon each port's current utilization. When a new port is selected to transmit a particular packet stream, it is done so that the packets cannot be forwarded out of order. This is preferably accomplished by ensuring passage of a period of time sufficient to allow all packets of a given stream to be forwarded by a port before a different port is allocated to transmit packets of the same stream.

International Classification:

H04L 12/56

US Classification:

370389, 370392, 370401

Abstract:

A cross stack port aggregation method and system associates a destination index with a received packet when it is provided to devices in the stack. Each device utilizes the destination index to access a descriptor identifying ports in the device included in the port aggregation group. An index generated from packet address data is used to select a bit in a group mask unique to each port.
