ABSTRACT:
A method and a system for allocating restoration capacity in a network link in a communications network provides that a common pool of communication capacity is provisioned in a network link, such that the common pool of communication capacity includes spare capacity for new service and restoration capacity. A pool of pre-allocated communication capacity for future growth of at least one connection in the network link is also provisioned. The pool of pre-allocated communication capacity for future growth is available for restoration capacity, but not for spare capacity for new service. The communications network can be, for example, a private line (PL) network, a SONET-based network, an Asynchronous Transfer Mode (ATM)-based network, an Internet Protocol/MultiProtocol Label Switching (IP/MPLS)-based network or a frame relay (FR)-based network.
