US 6,959,334 B1 · Backup logical port service

Abstract

Backup logical port service is provided by associating permanent virtual circuit (PVC) descriptions of a primary management information base (MIB) for a primary physical circuit with a service name that is also associated with a backup management information base and corresponding backup physical circuit. Switching from primary to backup service results in the PVC builds in the MIB for the primary circuit being established in the MIB for the backup circuit through association with the service name, rather than having an independently built set of PVCs in the backup MIB that may be error prone. Additionally, the backup service may be a full backup of all PVCs built to the primary service or a partial backup. Backup service may be configured and triggered by a terminal in communication with the management server, including client devices of customers accessing the management server through the Internet.

Claims23

Dependent claims

A method for providing backup logical port service in a network, comprising:

associating a service name to logical port information of a primary management information base that describes one or more permanent virtual circuits of a primary physical circuit;
associating the logical port information through the service name to a backup management information base;
applying the logical port information from the primary management information base to the primary physical circuit to establish the one or more permanent virtual circuits through the primary physical circuit when the primary physical circuit is active;
and
applying the logical port information of the backup management information base to a backup physical circuit to establish the one or more permanent virtual circuits through the backup physical circuit when the backup physical circuit is active.

2 more elements

A network employing backup logical port service, comprising:

a management server containing a primary management information base storing logical port information describing permanent virtual circuits of a primary physical circuit, the management server being configured to receive a service name and a backup physical circuit name, associate the logical port information to the service name, and establish a backup management information base through association of the logical port information with the service name;
a primary physical circuit in communication with the management server and configured to establish the permanent virtual circuits of the primary management information base when activated by the management server;
and
a backup physical circuit in communication with the management server and configured to establish the permanent virtual circuits of the backup management information base when activated by the management server.

1 more element

A network employing backup logical port service, comprising:

a management server containing a primary management information base having logical port information describing permanent virtual circuits of a primary physical circuit, the management server being configured to group a subset of the logical port information to a service name and establish a backup management information base through association of the subset of logical port information with the service name;
a primary physical circuit in communication with the management server and configured to establish the permanent virtual circuits described by the logical port information of the primary management information base when activated by the management server;
and
a backup physical circuit in communication with the management server and configured to establish the permanent virtual circuits described by the subset of logical port information of the backup management information base when activated by the management server.
