Abstract
According to one embodiment of the present invention, there is provided a method for providing security in a network environment that includes receiving a flow that propagates through an access gateway. The flow is initiated by an end user associated with the flow and propagates through a network. The method also includes receiving accounting information indicative of the termination of the flow. In response, tearing down of the communication associated with the flow is initiated.
Claims21
An apparatus for providing security in a network environment, comprising:
- a network element operable to receive a flow that propagates through an access gateway, the flow being initiated by an end user associated with the flow and propagating through a network, the network element further operable to receive accounting information associated with an internet protocol address, the accounting information indicating that the flow associated with the IP address has terminated, and, in response, initiate tearing down of a communication associated with the IP address.
A method for providing security in a network environment, comprising:
- receiving a flow that propagates through an access gateway, the flow being initiated by an end user associated with the flow and propagating through a network;
- and
- receiving accounting information indicative of the termination of the flow, and, in response, initiating tearing down of a communication associated with the flow.
A system for providing security in a network environment, comprising:
- means for receiving a flow that propagates through an access gateway, the flow being initiated by an end user associated with the flow and propagating through a network;
- means for receiving accounting information indicative of the termination of the flow;
- and
- means for, in response to receiving the accounting information, initiating tearing down of a communication associated with the flow.
Software for providing security in a network environment, the software being embodied in a computer readable medium and including computer code such that when executed is operable to:
- receive a flow that propagates through an access gateway, the flow being initiated by an end user associated with the flow and propagating through a network;
- and
- receive accounting information indicative of the termination of the flow, and, in response, initiate tearing down of a communication associated with the flow.
