Abstract
According to one embodiment, a method may include communicatively coupling a first network element to a second network element via a first path of a point-to-point network. The method may also include communicatively coupling the first network element to a third network element via a second path of the point-to-point network. The method may further include configuring the first path and the second path as paths of a linear protected switching connection such that traffic associated with a service and communicated via one of the first path and the second path may be switched over to the other of the first path and the second path in response to an event.
Claims19
A method comprising:
- communicatively coupling a first network element to a second network element via a first path of a point-to-point network;
- communicatively coupling the first network element to a third network element via a second path of the point-to-point network, wherein each of the first, second and third network elements comprises a plurality of network interfaces and a switching element coupling the plurality of network interfaces;
- and
- configuring the first path and the second path as paths of a linear protected switching connection such that traffic associated with a service and communicated via one of the first path and the second path may be switched over to the other of the first path and the second path in response to an event.
A network element, comprising:
- a processor;
- and
- one or more non-transitory computer readable media storing logic that when executed by the processor is operable to:
- communicatively couple the network element to a second network element via a first path of a point-to-point network;
- communicatively couple the network element to a third network element via a second path of the point-to-point network, wherein each of the network elements comprises a plurality of network interfaces and a switching element coupling the plurality of network interfaces;
- and
- configure the first path and the second path as paths of a linear protected switching connection such that traffic associated with a service and communicated via one of the first path and the second path may be switched over to the other of the first path and the second path in response to an event.
A network element, comprising:
- a processor;
- and
- one or more non-transitory computer readable media storing logic that when executed by the processor is operable to:
- communicatively couple the network element to a second network element via a first path of a point-to-point network;
- communicatively couple the network element and to a third network element via a synchronization connection, wherein each of the network elements comprises a plurality of network interfaces and a switching element coupling the plurality of network interfaces, wherein:
- the second network element and the third network element are configured to be communicatively coupled via a second path of the point-to-point network such that the first path and the second path may be configured as paths of a linear protected switching connection;
- and
- traffic associated with a service and communicated via one of the first path and the second path may be switched over to the other of the first path and the second path in response to an event;
- and
- configure the second network element and the third network element to synchronize status information for the linear protected switching connection between the second network element and the third network element via the synchronization connection.
