Patent ID: 7724668

Claim:
A computing-device implemented method, comprising: generating, by the computing device, a service protection factor (SPF i ) for links (N) on a link aggregation group (LAG), where generating a service protection factor (SPF i ) includes: calculating, by 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 ), calculating, by the computing device, a bandwidth allocated for a service class on the LAG before link failure (BF_B i ), calculating, by the computing device, a bandwidth allocated for the service class on the LAG after link failure (LF_B i ), and determining, by the computing device, the service protection factor (SPF i ) based on the calculations; determining, by the computing device, a traffic allocation bandwidth on the LAG for the service class based on the service protection factor (SPF i ); and restricting, by the computing device, the traffic allocation bandwidth on the LAG.
