System, device, and method for a voiding bandwidth fragmentation on a communication link by classifying bandwidth pools

摘要

A method and system for routing a connection on a communication network. A first bandwidth pool is classified as a long lived bandwidth pool and a second bandwidth pool is classified as a short lived bandwidth pool. The long lived bandwidth pool is used to route connections having a duration that are expected to equal or exceed a predetermined time. The short lived bandwidth pool is used to route connections having a duration that are not expected to exceed the predetermined time. A request to route a connection on the communication network is received. At least one characteristic of the connection is determined and is used to determine whether to route the connection on the long lived bandwidth pool or short lived bandwidth pool.

1. A method for routing a connection on a communication network, the method comprising:
receiving a request to route the connection on the communication network; classifying, by a processor, a first bandwidth pool that is free as a long lived bandwidth pool, the long lived bandwidth pool being used to route connections having a duration that is expected to at least one of equal and exceed a predetermined time; classifying, by the processor, a second bandwidth pool that is free as a short lived bandwidth pool, the short lived bandwidth pool being used to route connections having a duration that is not expected to exceed the predetermined time; determining at least one characteristic of the connection, the characteristic being used to determine whether to route the connection on one of the long lived bandwidth pool and short lived bandwidth pool; and advertising, via a control plane to nodes in the communication network, available bandwidth in each of the long lived bandwidth pool and the short lived bandwidth pool.
