For Huawei transmission devices, there are 2 types of protocols can be applied on management channels, which are IP over DCC protocol or HWECC protocol.
1. IP over DCC
Huawei's IP over DCC uses DCC or GCC channels to transmit TCP/IP protocol packets. Like the HWECC protocol, IP over DCC is used for communication between NEs. The difference between them is that IP over DCC transmits IP protocol packets using DCC or GCC bytes, but the HWECC protocol transmits Huawei-developed protocol packets using DCC or GCC bytes. Because IP over DCC uses the standard TCP/IP protocol, it can be used with a network-level protocol on third-party devices, facilitating network management.
2. HWECC
HWECC is a Huawei proprietary protocol stack. It is the most applicable and advanced ECC communication solution for Huawei transmission devices. The HWECC protocol stack distinguishes NEs by ID and creates routes automatically, making it easy to use. The HWECC protocol cannot be used with a network-level protocol on third-party devices. In general, it is used when only Huawei devices are used on a network.
