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

• Transport Flow Optimizations (TFO)

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

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

Minimize WAN transmission requirement

traffic locally

IPNetwork

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

Cisco WAAS True Enterprise Scalability + Availability

WAN

• WAAS eliminates 90-98% of requests from reaching the data-center

• Servers offloaded

• Highly scalable load balancing

• No single point of failure

…

Cisco WAAS

• Cisco ACE and WCCP v2 offer N+1 Failover

• Linear performance scalability by addition of additional appliances

• Read-ahead optimization increases server load

• More hardware required for HA

• Limited Solution Scalability

…

• Tunneling increases downtime risk

WAN
