16. 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

17. 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”.
