Improve Your WAN Optimise performance of TCP-based applications
across your WAN with Cisco WAAS, which combines application
acceleration technologies with WAN optimisation techniques.
The WAAS solution allows you to:
- Deploy centralised applications confidently
- Consolidate costly branch office servers and storage into
data centres
- Offer LAN-like performance to remote users
How it works
Unlike other WAN optimisation solutions, WAAS integrates
transparently with the network, preserving TCP information to
maintain functions such as security, QoS, visibility and monitoring.
WAAS is easy to deploy and manage and integrates with Cisco IOS software.
To accelerate application and file performance and to reduce WAN
bandwidth usage, Cisco WAAS incorporates application acceleration and
WAN optimisation techniques, including compression, redundancy
elimination, transport optimisations, caching and content distribution.
These techniques help overcome the bandwidth, throughput and latency
limitations associated with TCP/IP and application protocols.
Cisco WAAS achieves superior results over alternative offerings by
applying optimisation at three separate layers:
- Latency and bandwidth reduction at Layer 7, using
application-specific optimisations that suppress unnecessary
messages, perform message and operation batching and employ
sophisticated caching techniques to minimise data transfers
across the WAN
- Bandwidth and throughput improvement at Layer 4, using
techniques such as Data Redundancy Elimination (DRE), LZ
Compression and Transport Flow Optimisation (TFO) based on
extended TCP standards
- Transparent network integration at Layers 3 and 4, allowing
WAAS to take advantage of traffic classification, QoS, policy-based
routing, high availability, load balancing and other network policies.
