Abstract:
A method of dynamically reallocating connectivity resources in a communications system comprising steps of:receiving a request to establish a new connection for a call from a source node to a destination node, said call having a first priority status; computing a primary path for said new connection using a prescribed criterion; identifying an established connection of an ongoing call that is routed through a communication link on said primary path that does not have sufficient available bandwidth to accommodate said new connection, said identifying being for enabling rerouting of said established connection from said communication link to a new path so that said request to establish said new connection can be routed through said communication link on said primary path; rerouting said established connection of said ongoing call that had been routed through said communication link such that said established connection is rerouted to said new path that bypasses said communication link, said ongoing call of said established connection having a lower priority status than said new connection; and establishing said new connection through said primary path via said communication link, thereby enabling said call.
