Abstract
A system for selecting an alternate route in a network using a connection-oriented protocol. The system is implemented in response to inadequate resources to a normal next hop node for a requested connection. The system may also be implemented if the normal next hop node is not capable of supporting the requested data flow. An alternate next hop node is identified having adequate resources for the requested connection. The connection request is then sent to the alternate next hop node. A refusal message is generated if the connection request sent to the alternate next hop node fails. The identification of alternate next hop nodes having adequate resources is performed on a limited basis.
