Systems and methods for providing multi-layer protection switching within a sub-networking connection
First Claim
1. A sub-network connection system, comprising:
- line modules configured to receive bridged traffic signals over individual corresponding channels, said line modules being grouped into sets at a lower protection layer, said sets of line modules being organized into working legs and protection legs at an upper protection layer, wherein said line modules are activated/deactivated based on different upper and lower protection schemes associated with said upper and lower protection layers;
state maps associated with each of said line modules, said state maps storing state data that activates and deactivates said line modules, said state maps being updated in accordance with said lower protection scheme to perform intra-leg switching between said line modules in one of said working and protection legs, said state map being updated in accordance with said upper protection scheme to perform inter-leg switching between a first line module in one of said working and protection legs and a second line module in another of said working and protection legs; and
a network control module interconnected with said line modules, said network control module performing inter-leg switching by updating said state data in said state maps for corresponding line modules in associated working and protection legs.

Abstract
A subnetwork connection system is provided that includes line modules configures to receive traffic signals over bridged, individual corresponding channels. The line modules are grouped into sets at a lower protection layer, while the sets of line modules are organized into working legs and protection legs at an upper protection layer. The line modules are activated and deactivated based on different upper and lower protection schemes associated with the upper and lower protection layers. The subconnection system further includes state maps associated with each of the line modules. The state maps store state data that activates and deactivates the line modules. The state maps are updates in accordance with the lower protection scheme to permit intra-leg switching between the line modules in one of the working and protection legs. The state map is also updated in accordance with the upper protection scheme to perform inter-leg switching between a first line module in one of the working and protection legs and a second line module in the other of the working and protection legs. The subnetwork connection system also includes a network control module interconnected with the line modules. The control module performs inter-leg switching by updating the state data in the state maps for corresponding line modules in associated working and protection legs.
