AB  - The handling of instability due to link failures in a network 
  is an important problem while handling typical large scale networks. This issue 
  is particularly more challenging in optical networks operating under the wavelength 
  continuity constraint where the same wavelength must be assigned on all links 
  in the selected path. Hence, a fast and reliable Fault Recovery System is essential 
  in survivability design of very high bandwidth networks. The Generalized Loop 
  Back Recovery (GLBR) Method provides a solution for this kind of problem but 
  it handles only single link failure. Though the pre-configuration cycle accomplishes 
  multiple link failures, the length of restoration path provided by p-cycles 
  is longer and applicable for only small networks. This problem is alleviated 
  in the Star-Block algorithm but involves redundant procedures. In this study, 
  a new recovery scheme is proposed for single and multiple link failures which 
  eliminate the redundancy involved in Star-Block algorithm. A crossbar network 
  is used for the analysis and results are improved in reducing the length of 
  restoration path and number of iterations involved. Further, this scheme avoids 
  redundancy.
