Features and Functions of IP over DCC

IP over DCC has the functions and features that are different from the traditional DCC.

The DCC is used to transmit the OAM (operation, maintenance, and administration) data between NEs. The protocol stacks used by different vendors are not compatible with each other. Therefore, extra overhead bytes or service resources need to be allocated to transmit DCC data transparently in a network composed of multi-vendor products.

The IP over DCC meets most of the networking requirements in existing networks without occupying extra overhead bytes or service resources. The IP over DCC simplifies the network structure, saves network resources, and meets the networking requirements quickly.

The IP over DCC supports the following features:
  • Adopting the standard TCP/IP protocol, which makes it be compatible with other vendor's equipment and simplifies the network management
  • Adopting the forwarding function of the third layer in the protocol stack, which does not require extra overhead bytes or service paths
  • Bringing flexible networking models
  • Bringing simple upgrade modes and great compatibility. It is easy for IP over DCC to work with new forwarding or multi-protocol features on the application layer
