This permits a scalable approach to handling these diverse transmission requirements. CR-LDP is defined for the specific purpose of establishing and maintaining explicitly routed LSPs. Optional capabilities provide for negotiation of LSP services and traffic management parameters over and above best-effort packet delivery including bandwidth allocation, setup and holding priorities. Hence, it will work equally well for Multi-service switched networks, router networks, or hybrid networks. This applicability statement does not preclude the use of other signaling and label distribution protocols for the traffic engineering application in MPLS based networks.
Service providers are free to deploy whatever signaling protocol meets their needs.
There is currently Jamoussi, et. 2000 no consensus on which protocol is technically superior. Therefore, network administrators should make a choice between the two based upon their needs and particular situation. Describe, characterize and parameterize a wide variety of QoS scenarios and services including IP differentiated services, integrated services, ATM service classes, and frame relay. Steady state information required for proper maintenance of an LSP may be as little as 200 bytes or less.
