International Classification:

H04L012/56

US Classification:

370412, 370468

Abstract:

Methods and systems are provided for provisioning a network by identifying the classes of traffic to be transported in the network as well as the QoS criteria of the identified classes of traffic. By simulating the classes of traffic, one or more QoS mechanisms and their associated parameters may be determined. The statistical multiplexing gains of the classes of traffic may also be determined based on the simulation. Then, one or more resources in the network may be allocated based on the QoS mechanisms and parameters as well as the multiplexing gains.

Abstract:

Service attacks, such as denial of service and distributed denial of service attacks, of a customer network are detected and subsequently mitigated by the Internet Service Provider (ISP) that services the customer network. A sensor examines the traffic entering the customer network for attack traffic. When an attack is detected, the sensor notifies an analysis engine within the ISP network to mitigate the attack. The analysis engine configures a filter router to advertise new routing information to the border and edge routers of the ISP network. The new routing information instructs the border and edge routers to reroute attack traffic and non-attack traffic destined for the customer network to the filter router. At the filter router, the attack traffic and non-attack traffic are automatically filtered to remove the attack traffic. The non-attack traffic is passed back onto the ISP network for routing towards the customer network.
