Patent ID: 7974207

Claim:
A computing device-implemented method, comprising: determining, by a relationship determining component of the computing device, a relationship between a data delivery ratio after link failure (LF_DDR i ) associated with a time period (T), and a mean time to repair failed links (T r ) for a link aggregation group (LAG); determining, by a before failure bandwidth allocation component of the computing device, a bandwidth allocated for a service class on the LAG before link failure (BF_B i ); determining, by an after failure bandwidth allocation component of the computing device, a bandwidth allocated for the service class on the LAG after link failure (LF_B i ), sending the determined relationship, BF_B i , and LF_B i to a manipulator component of the computing device, and generating, by the manipulator component, a service protection factor (SPF i ) based on the determined relationship, BF_B i , and LF_B i for links (N) of the LAG.
