Method and system for network and intra-portal link (IPL) sharing in distributed relay control protocol (DRCP)
First Claim
1. A method supporting network and intra-portal link (IPL) sharing in a link aggregation group at a network device, wherein the network device and a neighbor network device are included in a portal of the link aggregation group, wherein the network device is coupled to the neighbor network device via an intra-portal port (IPP) using an IPL that is a logical point-to-point link between the network device and the neighbor network device, the method comprising:
- receiving a first type/length/value (TLV) message transmitted from the neighbor network device;
determining that the network device is configured with a network and IPL sharing method consistent with that of the neighbor network device, wherein the determining includes;
comparing a recorded neighbor network and IPL sharing method received from the first TLV message with a home network and IPL sharing method of the network device; and
transmitting frames between the network device and the neighbor network device using the network and IPL sharing method.

Abstract
A method supporting network and intra-portal link (IPL) sharing in a link aggregation group at a network device is disclosed. The method starts with transmitting frames on the IPL at the network device, where the physical link or aggregation link of the link aggregation group is dedicated to the IPL. The network device determines that the network device is configured with a network and IPL sharing method that is consistent with the neighbor network device, the network and IPL sharing method including sharing by at least one of time, tag, and encapsulation, where the network and IPL sharing method indicates sharing of the physical link or link aggregation between frames for the IPL and frames for another IPL or a network link of the link aggregation group. Then the network device transmits the frames between the network device and the neighbor network device using the network and IPL sharing method.

11. A network device supporting network and intra-portal link (IPL) sharing in a link aggregation group, wherein the network device and a neighbor network device are included in a portal of the link aggregation group, wherein the network device is coupled to the neighbor network device via an intra-portal port (IPP) using an IPL that is a logical point-to-point link between the network device and the neighbor network device, the network device comprising:
-
ports coupled to one or more physical or aggregation links of the link aggregation group; and a processor coupled to the ports, executing a distributed resilient network interconnect (DRNI) function, the DRNI function being operative to receive a first type/length/value (TLV) message transmitted from the neighbor network device, determine that the network device is configured with a network and IPL sharing method that is consistent with the neighbor network device, wherein the determination is to include to compare a recorded neighbor network and IPL sharing method received from the first TLV message with a home network and IPL sharing method of the network device, and further operative to cause transmission of frames between the network device and the neighbor network device using the network and IPL sharing method. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
