Tracing Layer-2 Route In Networks Based On Broadcast Medium

View page
US Patent:
7149794, Dec 12, 2006
Filed:
Apr 2, 2001
Appl. No.:
09/824844
Inventors:
Sailaja S K Attili - Karnataka, IN
Sridhar Aswathnarayan - San Jose CA, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
G06F 15/173
US Classification:
709223, 709224, 709238
Abstract:
Tracing the layer-2 devices present between any two systems in a network implemented using broadcast medium A device (receiving device) receives a command including a source and destination system identifiers. If the receiving device is not connected directly to the source system, the receiving device determines a connecting device connecting directly to the source system. The receiving system sends a request packet to the connecting device and receives a response packet. The response packet either indicates that the sending device is directly connected to the destination system or indicates a next device in the connecting path. The request and response sequence is continued until a sending device indicates that the destination system is connected directly.

Filed:
Nov 16, 2000
Appl. No.:
09/714246
Inventors:

Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
G01R 31/08
US Classification:
370219, 370244, 714 11
Abstract:
A method and apparatus allows for continued operation of one or more applications running at a network device with reduced delay despite crashes or failures at that device. The network device includes two or more supervisor cards for running the applications and a plurality of line cards. According to the invention, one supervisor card is designated the active supervisor card and one supervisor card is designated the standby supervisor card. As changes in state and other operating conditions take place on the active supervisor events are generating for passing at least some of this information to the standby supervisor where it is stored. Following a crash or failure of the active supervisor card, the standby becomes the newly active supervisor card. The standby supervisor performs a consistency check with the line cards and resets those that fail the check. The standby supervisor also determines which data records and state information stored at the standby supervisor are valid, and begins running the applications loaded onto the device.
