¿µ¹®³»¿ë¿ä¾à This specification is used to provide the protection and restoration mechanism with higher
reliability of control channels that are directly and indirectly connected between adjacent
nodes in GMPLS. For this purpose, the concept of common channel signaling (associated,
quasi-associated and non-associated modes) is applied and several functions to be needed are
identified via case studies and considerations for the protection and restoration of control
channels. As this mechanism is like a protocol, it includes supporting functions, message and
object definitions, and SDL.
3. Applicable fields of industry and its effect
This specification will provide a technical guideline for constructing a reliable control
network in a GMPLS network that data and control planes are separated. As applying the
specification in a GMPLS network, this will contribute to the development of GMPLS and the
activation of relevant application services.
