Deploying Riverbed with IBM WebSphere Portal produces significant benefits:

Improve business operations.• Companies that leverage corporate mashups via WebSphere Portal can dramatically reduce the amount of time it takes for employees to complete operations and access portal applications, improving productivity and operational throughput. Increased message throughput.

Faster deployment of applications.• IT organizations that need to respond to business and market drivers faster can deploy web-based applications quickly without fear of performance problems in a globally distributed environment.

Global Services Oriented Architecture •(SOA) scalability. SOA initiatives can overcome scalability limitations in a global enterprise and applets served by strategic partners can perform as if they were local.

Riverbed Optimization System (RiOS™) FeaturesRiOS software combines patent-pending data reduction, TCP optimization, application-level latency optimizations, and remote office file and management functionality. Together, these technologies provide a comprehensive solution for enterprise wide-area data services, scaling across a range of applications and network topologies to accelerate applications from 5 to 50 times, and sometimes up to 100x. RiOS consists of four key components:

Data Streamlining – RiOS data streamlining works across all TCP applications to reduce bandwidth consumption by 60% to 95%. Data streamlining works across Windows file sharing, Microsoft Office, Email (including MS Exchange and Lotus Notes), SSL-encrypted applications, CAD, ERP, databases, and all other applications that use TCP, to ensure the same data is never sent more than once over the WAN. Data Streamlining also supports rules-based policy administration of optimization classes and packet marking for QoS and route control.

Transport Streamlining – RiOS transport streamlining reduces the number of TCP packets required to transfer data by 65% to 98%. Transport streamlining overcomes TCP limitations by adapting transmission characteristics such as window scale, loss handling, congestion notification, and more. Transport streamlining also allows SSL-encrypted applications to be accelerated as well. RiOS Transport streamlining also enables greater utilization of high bandwidth, high latency connections with High-Speed TCP and MX-TCP.

Application Streamlining – RiOS application streamlining provides additional order-of-magnitude application performance improvements by reducing application protocol chattiness up to 98% and minimizing application overhead. By minimizing application demands on the network such as application protocol round trips and required network connections, RiOS can provide massive throughput increases to applications including Windows file sharing (CIFS), Exchange (MAPI 5.5 through 2007), Web (HTTP and HTTPS), and Database (MS-SQL). RiOS also includes important features for maximizing branch office productivity such as file server capabilities, transparent pre-population of popular data, and the Riverbed Services Platform (RSP) – a virtualized partition that can run run additional services and applications on Steelhead appliances without the need for a dedicated server.

Management Streamlining – RiOS simplifies the deployment and management of appli-cation acceleration infrastructure by employing a transparent approach to communications. RiOS enables easy deployment through auto-discovery of peers and auto-interception of traffic, with no reconfiguration of clients, servers, or routers necessary. RiOS simplifies ongoing management by providing simple but powerful Web-based and command line interfaces and reporting, as well as integrated, centralized management and configuration. RiOS also enables a host of additional management features including dozens of deploy-ment configurations, capabilities for redundancy, optional IPsec encryption, RADIUS/TACACS+ authentication, and SNMP traps.
