Cisco and Arbor Networks are partnering to deliver industry-leading DDoS mitigation capabilities on the ASR 9000 Series routers. This partnership extends the Peakflow solution by adding the Threat Management System (TMS) DDoS mitigation functionality to the ASR 9000. The TMS will be implemented on the ASR 9000 VSM (Virtualized Services Module) hosted in the ASR 9000 chassis. This solution enables unprecedented scaling of the DDoS mitigation architecture, reduces operational complexity and hardware footprint, and allows network providers to push attack mitigation to the edge of the network which reduces network loads from backhauling attack traffic to centralized scrubbing centers. This whitepaper presents an overview of the solution.
