US Patent:

20030048501, Mar 13, 2003
Filed:

Sep 12, 2001
Appl. No.:

09/952284
Inventors:

Michael Guess - Austin TX, US
Paul Niezgoda - Austin TX, US
Fraser Street - San Jose CA, US
International Classification:

H04B010/20
H04J014/00
G02B006/28
US Classification:

359/118000, 385/024000
Abstract:

A local access fiber optical distribution network is disclosed in which a dedicated pair of diversely routed optical fibers is routed in the distribution network for each customer. In a preferred embodiment, a dual physical overlay ring core topology is used in the core. The distribution network includes working and protection logical path connectivity. No 802.1D Spanning Tree is required for recovery, providing resilience to any single network failure in any device or link, quick recovery times from failure, and a failure detection/recovery protocol that is not active on any devices other than the devices directly attached to the subscriber.

US Patent:

20030048746, Mar 13, 2003
Filed:

Oct 11, 2001
Appl. No.:

09/975474
Inventors:

Michael Guess - Austin TX, US
Paul Niezgoda - Austin TX, US
Fraser Street - San Jose CA, US
International Classification:

H04J003/14
US Classification:

370/219000, 370/221000
Abstract:

A failover transition system for a VLAN is disclosed in which a master switch and a standby switch are designated, as in the case of ESRP. When a network failure is detected, the master switch “bounces” or restarts auto-negotiation of a set of physical ports on the VLAN. In this way, ports are forced to re-ARP to update their forwarding database information immediately rather than wait until expiration of an ARP max age timer, resulting in a decreased failover transition time.
