Product Overview
Is your network protected from DDoS attacks? The potential for damage is at an all-time high. The power, frequency, and size and size of these attacks continue to increase at an alarming rate. Results include downtime, potential loss of revenue, decreased network availability, and undue media attention. It is critical to protect your network from these attacks.
Cisco and Arbor Networks have collaborated to bring an industry-leading DDoS solution to this problem. The Cisco ASR 9000 Virtual DDoS Protection solution can create a secure perimeter around your network. And the solution allows you to scale for large and growing service provider and enterprise requirements.
The solution is targeted for deployment at peering points, data center and cloud edge, and enterprise WAN edge to effectively create a secure perimeter around networks. The vDDoS solution runs on the Cisco ASR 9000 Series Virtualized Services Module (VSM) and is scalable up to 40 Gbps per VSM.
The ASR 9000 vDDoS Protection solution is typically deployed as an “on-demand” solution but can be configured to work in persistent mode. In the “on-demand” mode, only the traffic addressed to the target of the attack is diverted to the vDDoS solution on the VSM; normal traffic is not affected. The vDDoS solution on the VSM module then identifies and blocks malicious attack traffic while allowing legitimate traffic to flow through to its original destination. Business operations continue uninterrupted, even in the midst of a DDoS attack.
The ASR 9000 vDDoS Protection solution is a scalable solution allowing customers to incrementally scale up with just a license or they can install multiple VSMs[1] in a single chassis, incrementally scaling to multiple times the capacity of a single Cisco ASR 9000 Series VSM. This scenario allows the service to scale for large and growing service provider and enterprise requirements.
Evolving DDOS Attacks
DDoS attacks are denial-of-service attacks that take advantage of the compute power of infected devices targeting networks and web servers with a goal of disrupting normal operations costing billions of dollars per year in losses - from lost transactions and customers to damaged reputations and legal liabilities. Today’s DDoS attacks are more malicious, destructive, and focused than ever. Launched by disgruntled users, unscrupulous businesses, and extortionists targeting specific sites or competitors, these attacks can easily elude and overwhelm the most common defenses. The ASR 9000 vDDoS Protection solution defends against different types of DDoS attacks, enabling businesses to identify and block malicious traffic without compromising their mission-critical and revenue-bearing operations. Cisco ASR 9000 vDDoS Protection solution uses advanced anomaly-recognition capabilities to dynamically apply integrated source verification and anti-spoofing technologies in conjunction with Intelligence filtering to identify and block individual attack flows while allowing legitimate transactions to pass.

Features and Benefits
Multigigabit Performance
Each VSM is loaded with high-performance processing capabilities to enable attack traffic analysis and cleaning of the traffic, enabling a defense against large-scale DDoS attacks. Multiple VSMs[3] can be installed in a single ASR 9000 Series router to provide additional scaling of throughput.
Different Attack Vectors Mitigated
One of the key benefits of the ASR 9000 vDDoS Protection solution is maintaining blocked lists and allowed lists. The allowed list contains authorized hosts, whereas the blocked list contains hosts that have been compromised and whose traffic needs to be blocked. These blocked lists are loaded on the line cards in an ASR 9000 router, effectively increasing the scaling of the solution. This feature can scale 100 Gbps or more with a single VSM in an ASR 9000.
The solution uses complex countermeasures to block application layer exploits. HTTP-specific attacks are detected and mitigated by the solution. DNS services are protected against cache poisoning, resource exhaustion, and amplification attacks. Large reflection attacks such as NTP, DNS, or SNMP are also mitigated by the solution.
Dynamic Diversion
The Cisco ASR 9000 vDDoS Protection solution deploys an “on-demand” scrubbing model. In a typical deployment it is not inserted in the normal data path of the traffic, but can be configured to be inserted in line if the customer so desires; it employs dynamic diversion to automatically redirect only the traffic destined for the destination under attack while the rest of the traffic follows the normal data path. Redirection of the traffic is transparent and can be accomplished using Border Gateway Protocol (BGP) or BGP Flow Spec, etc.
When traffic is scrubbed, all clean or legitimate traffic is then forwarded to the final destination, helping ensure that no critical traffic is lost. By limiting the diverting traffic to only that destined for the target under attack, the vDDoS Protection solution provides optimal resource usage, transparency, and reliability for a scalable solution.
Summary
The Cisco ASR 9000 vDDoS Protection solution is designed for both the service provider and enterprise customers. The solution helps ensure that our customers have uninterrupted business operations, even in the face of the most malicious attacks. Sitting at the edge of the network, the solution provides a secure boundary around the network to safeguard customer network infrastructure and services.
