Abstract
Compsite service recovery is an important issue not fully investigated, while the network recoery is investigated deeply. A model is defined in the paper to transform the problem of composite service recovery to a problem of network recovery. A new scheme for composite service recovery is proposed which integrate LSP Tunnel Recovery into composite service recovery. Two existing LSP tunnel recovery schemes are compared and a new integrated scheme is proposed. Simulation and theoretical analysis show the effectiveness of the scheme. A packet reordering theory is put forward in analyzing the packet reordering.
