The Cisco Catalyst 6500/Cisco 7600 Router Anomaly Guard Module is an integrated services module for Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers that delivers a powerful and extensive solution for defending online resources against massive distributed denial-of-service (DDoS) attacks. Designed to meet the performance and scalability requirements of the largest and most-demanding enterprise and service provider environments, the Cisco Anomaly Guard Module delivers unprecedented levels of protection for defeating today's increasingly complex and elusive attacks.A single Cisco Anomaly Guard Module provides the platform for processing attack traffic at Gbps line rates. The Anomaly Guard Module employs a unique "on-demand" deployment model, diverting and scrubbing only traffic addressed to targeted devices or zones without affecting other traffic. Within the module, integrated multiple layers of defense enable the Anomaly Guard Module to identify and block malicious attack traffic while allowing legitimate transactions to continue flowing to their original destinations. Business operations continue uninterrupted, even in the midst of a withering attack.Multiple Cisco Anomaly Guard modules, working together in a single chassis, can incrementally scale to support many times the single module rate, delivering a scalable solution that easily adapts to large and growing enterprise and service provider environments. The Anomaly Guard Module's multiprocessor architecture can support future licensed software upgrades to enhance and improve performance for defending against massive attacks.
