Vendor Name:   Riverbed Technology Solution Type:   Distributed Solution Names:   Steelhead Appliances Interceptor Central Management Console Generic Technique Name (see "Field Guide to Application Delivery Systems" for Definitions) Does your Distributed ADS solution do this? If yes, what do you call this technique? If yes, list the protocols this technique supports. Control Yes No     Traffic Analysis & Capacity Planning Reporting Both Steelhead Appliances and the Central Management Console (CMC) allow for detailed traffic analysis and trending for ALL traffic on the network (TCP and UDP). Analysis includes traffic breakdown per application, per port, per network connection, Traffic summaries are available for optimized traffic AND pass-through traffic. The CMC also offers global traffic summaries. Traffic Marking Part of RiOS v 3.0 (Riverbed Optimization System, the software on Steelhead appliances) - Quality of Service (QoS) All WAN traffic, both UDP and TCP based can be prioritized using Hierarchical Fair Service Curves (HFSC), ensuring the optimal bandwidth is allocated while also prioritizing latency-sensitive traffic (like VOIP) separately. These include CIFS, NFS, HTTP, XML, HTML, VOIP, Real Time Video or IP Video, and all other WAN traffic. Bandwidth Allocation Part of RiOS v 3.0 (Riverbed Optimization System, the software on Steelhead appliances) - Quality of Service (QoS) All WAN traffic, both UDP and TCP based can be prioritized using Hierarchical Fair Service Curves (HFSC), ensuring the optimal bandwidth is allocated while also prioritizing latency-sensitive traffic (like VOIP) separately. These include CIFS, NFS, HTTP, XML, HTML, VOIP, Real Time Video or IP Video, and all other WAN traffic. Priority Handling Part of RiOS v 3.0 (Riverbed Optimization System, the software on Steelhead appliances) - Quality of Service (QoS) All WAN traffic, both UDP and TCP based can be prioritized using Hierarchical Fair Service Curves (HFSC), ensuring the optimal bandwidth is allocated while also prioritizing latency-sensitive traffic (like VOIP) separately. These include CIFS, NFS, HTTP, XML, HTML, VOIP, Real Time Video or IP Video, and all other WAN traffic. TCP Rate Control Part of RiOS v 3.0 (Riverbed Optimization System, the software on Steelhead appliances) - Quality of Service (QoS) All WAN traffic, both UDP and TCP based can be prioritized using Hierarchical Fair Service Curves (HFSC), ensuring the optimal bandwidth is allocated while also prioritizing latency-sensitive traffic (like VOIP) separately. These include CIFS, NFS, HTTP, XML, HTML, VOIP, Real Time Video or IP Video, and all other WAN traffic. DoS Attack Prevention Acceleration Yes No     Comprehensive TCP Optimization Transport Streamlining All TCP-based WAN traffic is highly optimized between Steelhead appliances allowing higher throughput on both low bandwidth links, as well as "fill the pipe" functionality for very high bandwidth links. Packet Packing Header Compression Forward Error Control Dynamic Compression Part of Data Streamlining All new TCP based traffic is compressed using L-Z techniques. Thereafter repeated WAN data is reduced using disk-based dictionary compression (data reduction) techniques Dictionary Compression Part of Data Streamlining All TCP-based traffic is segmented and stored in an application independent manner; on subsequent trips containing the same bytes, that data will not be re-sent. Remote File Caching * * Part of Data Streamlining - Riverbed does not cache files; rather we store the data that comprises all WAN traffic, which includes file system traffic All data, including data comprising files (but not the files themselves), is stored on Steelhead appliances in the form of segments and groups of segments. This is more effective than caching of the file objects themselves. Application Turn Reduction Application Streamlining Application Streamlining offers additional optimizations for specific applications, and is implemented for: - Windows File Sharing (CIFS) - UNIX File Sharing (NFS) - MS-Exchange (MAPI) 5.5, 2000, 2003 - MS-SQL - Backup / Replication - HTTP IT Services * * Part of Application Streamlining, Data Streamlining, and Proxy File Services Some parts of "IT Services" are handled by Steelhead appliances: The equivalent of File Caching (see Data Streamlining; storing data segments), as well as optimization of any other data (including SMS) without any special code. Print services and DNS. File locking and consistency checks are handled by the file system; it's not necessary for Riverbed to handle that because our products are not caching "files". All TCP based WAN traffic is optimized by Data Streamlining. Specific applications (see above) are optimized by Application Streamlining. Proxy File Services (PFS) can be enabled to provide for access to files in the branch in the event of a WAN failure. It is not necessary to leave a file server, email server, SMS server, filer, and so forth in the branch. Content may also be pre-populated to Steelhead appliances using various mechanisms supported by the Central Management Console (CMC)
