Abstract

Various embodiments relate to a communications system and related method of advertising available bandwidth capacities of leased links. After leasing a link to an operator device, a provider or operator may monitor the available capacity of the leased link and generate an advertising frame when the actual available capacity is below the defined leased capacity of the link. The advertising frame may be an L2 Ethernet frame in a form similar to the routing protocol used in the communications network to avoid additional strain and complexity in the network due to additional protocols for traffic engineering. After propagating the new information throughout the network using the advertising frame operator devices may redirect or shape their traffic of data in response to the updated available capacity on the leased link.
