Protecting hybrid equipment in a network node

1. A method for providing port level protection for a hybrid interface, comprising:

establishing a Virtual Connection Point (VCP) as a termination point for a transport-side network connection;

configuring the VCP as a Layer 1 bridge/select connection to switch among any one of a plurality of backplane Layer 1 termination points;

creating a link aggregation group to protect the plurality of backplane Layer 1 termination points, wherein the link aggregation group is configured between modules and over a backplane within a node, and wherein the link aggregation group comprises a first link aggregation group;

establishing a Layer 2 switch to direct packets between the link aggregation group and the VCP configured as the Layer 1 bridge/select connection; and

creating a second link aggregation group to protect one or more client-side Ethernet ports, wherein the Layer 2 switch further directs packets between the first link aggregation group and second link aggregation group, and wherein the second link aggregation group is configured between the node and another device,

wherein the first link aggregation port is between the Layer 2 switch and a Layer 1 switch fabric and the second link aggregation port is between the Layer 2 switch and the one or more client-side Ethernet ports.

2. The method of claim 1 , further comprising:

assigning logical Ethernet ports to Layer 1 termination points, wherein members in the link aggregation group include the assigned the logical Ethernet ports to protect the backplane Layer 1 termination points.

4. The method of claim 1 , wherein the backplane Layer 1 termination points comprise one or more of Synchronous Optical Networking (SONET) termination points or Synchronous Digital Hierarchy (SDH) termination points.

5. The method of claim 1 , wherein the VCP is established in the Layer 1 switch fabric.

6. The method of claim 5 , wherein the VCP is realized in a center stage of a three-stage Clos switch.

7. The method of claim 1 , wherein the VCP provides a termination point for one or more of a Subnetwork Connection (SNC) or a Label Switched Path (LSP) tunnel.

8. The method of claim 1 , wherein the link aggregation group is single-ended and lacks a far-end peer.

9. The method of claim 8 , wherein the link aggregation group runs in a link aggregation group (1+1) configuration.

at least one control module;

at least one switching module having switch fabrics that can independently function at both Layer 1 and Layer 2;

at least one hybrid services line module functionally coupled to the at least one control module and the at least one switch module through a backplane, wherein each of the control module, the switching module, and the hybrid services line module is a hardware module in the node; and

at least one processor configured to

establish a Virtual Connection Point (VCP) in the at least one switching module as a termination point for a transport-side network connection,

configure the VCP as a Layer 1 bridge/select connection to switch among any one of a plurality of backplane Layer 1 termination points,

create a link aggregation group to protect the backplane Layer 1 termination points, wherein the link aggregation group comprises a first link aggregation group,

establish a Layer 2 switch to direct packets between the link aggregation group and the VCP configured as the Layer 1 bridge/select connection, and

create a second link aggregation group to protect one or more client-side Ethernet ports;

wherein the link aggregation group is configured between the at least one switching module and the at least one hybrid services line module over a backplane within the node, wherein the Layer 2 switch is further configured to direct packets between the first link aggregation group and second link aggregation group, and wherein the second link aggregation group is configured between the node and another device, and

wherein the first link aggregation port is between the Layer 2 switch and a Layer 1 switch fabric and the second link aggregation port is between the Layer 2 switch and the one or more client-side Ethernet ports.

11. The node of claim 10 , wherein the at least one processor is further configured to:

assign logical Ethernet ports to Layer 1 termination points, wherein members in the link aggregation group include the assigned logical Ethernet ports to protect the backplane Layer 1 termination points.

12. The node of claim 10 , wherein the backplane Layer 1 termination points comprise Optical Transport Network (OTN) termination points and the OTN termination points comprise Optical Data Unit (ODUk) termination points.

13. The node of claim 10 , wherein the backplane Layer 1 termination points comprise one or more of Synchronous Optical Networking (SONET) termination points or Synchronous Digital Hierarchy (SDH) termination points.

14. The node of claim 10 , wherein the VCP is established in the Layer 1 switch fabric.
