Patent ID: 8897173

Claim:
A system comprising: at least one carrier network; and a device associated with the system, the device including at least a processor and a memory coupled to the processor, the memory including instructions executable by the processor to: select, from a plurality of traffic paths within the at least one carrier network, a traffic path based on a quality of service function, wherein the quality of service function is Q i =Q(d i ,i i ,l i ,r i )=r i *(w d *e −d i /D +w j *e −j 1 /1 +w l *e −l i /L ), where r i is the mean service availability of the carrier network i, d i , i i and l i are the mean delay, mean jitter, and mean frame loss rate of the carrier network i, respectively, d, i, and l represent values of the frame delay, jitter, and frame loss rate, respectively, and w d , w j , and w l are the weights of delay, jitter, and frame loss rate, respectively.
