Cisco CSS 11150

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.
