ABSTRACT:
In general, techniques are described for automatically releasing network resources reserved for use by network devices within a network. In particular, a network device, such as a router, may include an interface card that receives a first and a second message from respective first and second client devices requesting reservation of network resources. The first message may include a first identifier, while the second message may include a second identifier. Both messages however may also include the same additional context information that identifies the same context in which the first client device operates. The router may include a control unit that determines whether the additional context information included within the first and second messages is the same. Based on a determination that this information is the same, the control unit may automatically release resources reserved for use by the first client device within the network.
