WAAS Addresses WAN Performance Impact Problem Solution Cisco IOS/WAAS Technology Latency Mitigation Reduced roundtrips from chatty application protocols Faster connection setup Intelligent Protocol Proxies Transport Flow Optimizations (TFO) Bandwidth Management Offload the WAN by preventing requests from going to the WAN Improve application response time on congested links by reducing the amount of data sent across the WAN Caching Data Redundancy Elimination (DRE) Persistent Session-Based Compression Content Distribution & Pre-positioning Link Throughput Improvement Improve network throughput by reducing TCP-related errors Traffic Prioritization Prioritize selected jitter-sensitive traffic (e.g. VoIP, Video) over the packet network Cisco IOS QoS, NBAR, NetFlow Local Services Replacement for services that branch office servers provide Centrally managed remote services interface Local print services

Cisco WAAS Optimization Architecture Unified Management Video Web Enterprise Apps Email File Services Local Services Other Apps L7: Application Optimization Content Distribution TCP Flow Optimizations (TFO) Persistent Session-Based Compression Data Redundancy Elimination (DRE) L4: Transport Optimization Application Classification and Policy Engine Logical and Physical Integration Network Infrastructure Security Monitoring Quality of Service Core Routing & Switching Services

Application-Specific Intelligence Compression doesn’t address latency - every message must still traverse the WAN Cisco ‘Application Adapters’ eliminate unnecessary chatter Protocol proxies handle messages locally where applicable Local object caching retain data close to client Data Integrity and Concurrency preserved Manage majority of application traffic locally IP Network Minimize WAN transmission requirement The best way to overcome latency is not to go across the WAN… The ‘trick’ is to intercept application/protocol-level messages and be able to handle most of them locally. Without jeopardizing application behavior or data integrity! That’s what our application adapters (or proxies) do. We also utilize ‘object caching’ to store data close to the client. Object caches “understand” the type of objects application access. For example – a file, a web page, a gif image, a video stream - are all “objects”. By intelligently handling “objects” caches can support higher order operations much more efficiently. In addition, our content distribution technology (CDN) enables distribution of data to the edge proactively, in convenient times (e.g. off hours). Files (or objects) distributed are still checked for freshness. Between the ACNS and WAFS modules, Cisco owns the largest set of application adapters. We support protocols in the web, file and video space. Effectively and safely offload core and origin servers NAS

Data Redundancy Elimination (DRE) Reduce overall WAN consumption based on redundancy Maintain active database of previously sent and received traffic Send database index on behalf of traffic that has been seen before Realize 5x – 50x compression, minimize WAN bandwidth consumption Compress all outbound traffic with LZ compression Additional 2x compression beyond data suppression Very good compression for non-redundant data DRE exploits commonality between payloads that traverse a particular link. A sophisticated, content-based pattern recognition function identifies repeatable patterns (“chunks”). Those are stored and indexed in a “segment cache” on both sides. Once a pattern has been cached, future transmissions require only a small “key” (aka signature) to be re-transmitted across the WAN. LZ compression algorithm is applied to data transmitted the first time, or in the event of a “segment cache miss”.
