Content Services Switch

CREATE HIGH-PERFORMANCE WEBSITES WITH CUSTOMER-FOCUSEDWEB NETWORK SERVICES

Data Sheet

The Cisco CSS 11150 content services switch is a compact, high-performance solution for small-to medium-sized Web sites. Featuring Cisco Web Network Services (WebNS) software, the Cisco CSS 11150 enablesWebandapplicationserviceproviders, Web content providers, and enterprises engaged in e-commerce to build global W eb networksoptimizedfore-commercetransactions andWebcontentdelivery. Withits patented content switching technology , the Cisco CSS 11150gives businesses maximum controlin ensuring availability oftheirWebsites, securing Website resources without compromising performance, and allocating Web site resources efﬁciently.

Running on the Cisco CSS 11150, Cisco Web NS software knows who the user is, whatthe userwantsto do, andhow best to servicetheuser’srequestwithinaglobalWeb infrastructure.TheCiscoCSS11150supports wire-speed flow forwarding betweena client and a Web server, based on the requested content’ sfull URL,as well as user cookieand extensive resource verification information.

Built for Web Traffic

The Cisco CSS 11150 combinescentralized processingandmemory resources forpolicybased ﬂow setup with distributed network processors that support wire-speed flow forwarding, in a single platform. The Cisco CSS 11150 Content Policy Engine consists of a high-speed RISCprocessor, 128MB of memory, and 5.0 Gbps of throughput and delivers per-ﬂow prioritization based on hundredsof user-defined policies. Distributed flow-forwarding engines feature per-port programmable network processorsfor wirespeed delivery of Web content.

Built to address the requirements of Web traffic, this unique architecture combines performanceandintelligence,allowingWeb site operators to ﬂexibly distribute content in a local or distributed Webfarm. This intelligence also allows users to reduce costs by maximizingthe useof server,cache, andnetwork resources forspecificcustomers, applications, or content.

Cisco Web NS Software

With the industry’s most comprehensive URL- and cookie-based switching, Cisco Web NS software lets network managers tailor customer or content-specific service agreements, offer premium services for preferred customers, and deploy content delivery services for streaming audio and video, distance learning, and Internet audio andvideo broadcasting. Support for“sticky”connectionsbasedon IP address, secure socket layer (SSL) session ID, and cookies ensures reliability and security for e-commerce transactions.

The uniqueCisco content replication technology enables dynamic expansion of site capacity in response to sudden “flash crowds” for “hot” content, or seasonal peaksin traff icthat can overwhelmservers.

Local, Global, and Application Load-Balancing

Cisco CSS 11000 series switches learn where specific content resides, either locally or remotely, and dynamically select the best Web server or cache for specific content requests—ending frustrating error messages such as “Server Not Found.” In a distributed Web site, Cisco CSS 11000 series switches perform comprehensive resource veriﬁcation before routing user requests, ensuring they are directed to the location that has the best response time and the least load for the requested content. Local server selection is based on server load and application response time, as well as traditional least connections and round-robin algorithms. Global server load balancing is based on Domain Name System (DNS) and proximity by source IP address. Any application that uses standard Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) protocols can also be load-balanced including firewalls, mail, news, chat, and lightweight directory access protocol (LDAP).

Site and System Security

Cisco CSS 11000 series switches ensure high levels of security without compromising site performance, providing wire-speed, per-flow filtering of content requests. Security policies can be implemented based on any combination of source address, destination address, protocol, type,or content URL.Intelligent flow inspection

prevents common denial of service attacks such as SYN floods, ping floods, and “smurfs.” Wire-speed network address translation protects server IP addresses.

For backend system security, Cisco CSS 11000 series switches intelligently direct trafficacross multiplerouters, SSL encryption hardware, and firewallsecurity servers. Firewall load balancing eliminates system downtime that results when an overloaded security serverfails orshuts down, closing off the connection to the network, and disrupting e-commerce purchases or other missioncritical transactions.

Advanced System Management

System management capabilities include a powerful command line interface (CLI),a graphical user interface (GUI), and support for Simple Network Management Protocol (SNMP), remote monitoring (RMON), and log files. Effective management tools reduce the ongoing cost of operating a business-critical Web site.
