Abstract:
1. A call routing system to route a call to a termination, comprising: a first set of routers; a second set of routers; wherein, the first set of routers and the second set of routers each implement a routing scheme, the routing scheme being parameterized using dynamic distribution parameters, the dynamic distribution parameters specifying dynamically determined capacity information of the second set of routers, when in operation, a first router of the first set of routers: receives a call; identifies, using a first weighted random probability function, a group of the second set of routers to route the call to; wherein, the first weighted random probability function is determined using the dynamically determined capacity information of the second set of routers specified in the dynamic distribution parameters; wherein, when in operation, a second router in the group of the second set of routers selects, based on the routing scheme, the termination to process the call.
