PREMIER TRAFFIC MANAGEMENT FOR E-BUSINESS

In addition to the Cisco CSS 11500 Series, Cisco Systems

delivers a complete product line that includes the Cisco CSS 11501, CSS 11501S-C, CSS

11503, CSS 11506, and content switching modules (CSM/CSM-S) integrated service modules for the Cisco Catalyst

6500 Series Switch and Cisco

7600 Series Router. The Cisco CSM attains superior performance and offers transport and application (Layer 4 to 7) features as rich as those

in WebNS Software. Through full integration with Cisco IOS

Software, the Cisco Catalyst 6500 Series Switch, and the Cisco 7600 Series Router,

Cisco CSM also supports high port density and comprehensive internetworking features. The Cisco CSM-S provides all the functionality of

the CSM, and adds hardware acceleration of SSL processing. Together, the Cisco CSS 11500 and CSM are ideal choices for enterprises and service

providers deploying content services.

NEW STANDARD IN HIGH AVAILABILITY

The Cisco CSS 11500 delivers Adaptive Session Redundancy (ASR), a method for achieving stateful Layer 5 session redundancy feature that

enables failover of important flows while maximizing performance.

Some flows, such as a long-lived FTP or a database session, may be mission-critical, but many flows are not. Most of today’s solutions require all

traffic—important or not—to be backed up from one unit to another. If the majority of flows are not critical, most of system performance is wasted

on unnecessary backups.

With ASR, the Cisco CSS 11500 can be configured so that critical flows are marked as replication-worthy, whereas others need not be marked as

such. ASR focuses traffic management resources precisely where needed.

SSL AND COMPRESSION INTEGRATION FOR SECURITY, SERVER, AND WAN OPTIMIZATION

Cisco offers a scalable, hardware-based integrated SSL and compression solution. SSL, the industry standard for secure transport of traffic from

client browsers to Web servers, presents two critical challenges for today’s e-business infrastructure. First, because SSL encrypts data and headers,

it obscures the request-specific information on which Layer 4 to 7 switching decisions are made. Second, SSL authentication places a high

processing load for each SSL flow setup.

The Cisco CSS 11500 with integrated SSL modules meets both of these challenges by combining leading SSL acceleration technology with

the Cisco WebNS technology. In addition to superior price performance, the SSL module simplifies the management of digital certificates.

The latest hardware module to be added to the Cisco CSS 11500 product line is capable of supporting both SSL acceleration and HTTP compression

independently or simultaneously. This combination of supporting SSL transaction and compression in the same module delivers the following

benefits:

• Server-based compression and SSL termination, intensive processes that can rob server performance needed for computational tasks; with this

new module, network designers can offload these processes to the Cisco CSS 11500.

• Both secure and non-secure client traffic can enjoy the improved server response times associated with HTTP compression.

• SSL and compression capacity can be scaled by adding additional modules to the Cisco CSS 11500 Series.

• Network designers will see a reduction in WAN bandwidth consumption for both secure and non-secure Web traffic.

The compression module takes advantage of the decompression capability found in all Web browsers. Traditionally the compression responsibility

was assigned to the server. Now, this task can be offloaded to the Cisco CSS 11500. This feature supports a lossless data compression algorithm and

two file formats GZIP (GNU zip) and Deflate.

By combining support for SSL acceleration and HTTP compression, Cisco offers new possibilities in optimizing the switch-to-server architecture

for data center security and optimization.
