Before using the HWECC solution, familiarize yourselves with the basic concepts of this solution.
HWECC
The HWECC protocol stack is a proprietary protocol stack of Huawei. It is the most applicable and advanced ECC communication solution for Huawei transmission devices. The HWECC protocol stack identifies NEs by IDs and creates routes automatically, which is easy to use.
Extended ECC
The extended ECC refers to the HWECC protocol stack that is loaded on the TCP/IP protocol stack. That is, the HWECC protocol stack is carried through the extended channel (such as Ethernet) instead of the DCC channel to meet the requirements of special situations, for example, DCN communication between NEs that are not connected using fibers.
