Application-Specific Intelligence
• Compression doesn’t address latency every message must still traverse the WAN
Manage
majority of
application
traffic locally
• Cisco ‘Application Adapters’ eliminate
unnecessary chatter
• Protocol proxies handle messages locally
where applicable
• Local object caching retain data close to
client
IP
Network
Minimize WAN
transmission
requirement
• Data Integrity and Concurrency preserved

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
