Preface: Introducing the WAAM
Features and Benefits
The WAAM’s new and improved algorithms provide the highest WAN compression performance available, in an easy to install package that fits seamlessly into various network topologies such as MPLS, QoS clouds, Noisy networks, High BER networks, Load balanced networks, and networks experiencing many out-of-order errors.
Redefining Application Traffic Management
The WAAM takes application traffic management to the next level by reducing WAN costs and improving application performance. In addition to bandwidth compression capabilities, the WAAM provides a rich set of features that improve application response times and provide Layer-7 visibility and control tools, which enable network managers to align network resources with business priorities. Acceleration of application response times is achieved through next-generation WAN compression, application-specific acceleration, Layer-7 QoS capabilities and sophisticated monitoring and reporting.
Next-generation WAN Compression
The WAAMs’ bandwidth expansion algorithms provide an effective alternative to WAN upgrades with a 3 to 9 month ROI.
Average 100% to 400%+ additional capacity, peaks of 1000%+
Combination of byte-level caching, packet header reduction and adaptive packet compression.
High performance, low latency algorithms
Packets incur a maximum of 1 millisecond latency passing through the device at all times.
100% lossless, works on all applications.
Supports up to 350 remote sites and 45 Mbps in a single device.
Unique On-LAN deployments enable rack-and-stack above 350 sites and 45 Mbps.
Verified in over 20,000 production installations.
Network transparent RTM (Router Transparency Mode) enables 100% IP header preservation ensuring guaranteed compatibility with any kind of WAN device.
Application-specific Acceleration
Application-specific acceleration is a breakthrough approach that works in combination with next-generation compression for improving application response times.
Improves application response times by 100% to 400%, peaks of 1000%+
Extensible architecture based on application acceleration plug-ins for additional application support
TCP acceleration enables TCP transfer speeds in excess of WAN link speed, even under challenging latency and packet loss conditions. The TCP acceleration plug-in is standards-based, meeting the SCPS standard (www.scps.org) that was developed by NASA and the DoD for performance optimization in high latency links.
HTTP acceleration provides faster web application response times for chatty HTTP transactions by eliminating repetitive download of frequently accessed objects, applets, and so on.
FTP acceleration provides faster response times due to elimination of long FTP transactions by keeping local copies of frequently accessed files.
Layer-7 QoS and Bandwidth Management
The WAAMs’ Instant QoS functionality stops bandwidth abuse, guarantees network resources for critical applications like VoIP and lets network managers prioritize network applications according to business objectives.
Low operational cost QoS solution, Layer-7 application discovery Easy to set-up – Instant QoS Maximum flexibility for advanced users
QoS can be applied for both In-bound and out-bound traffic
Bandwidth limits: desired, maximum
Strict priority for real-time traffic
Shaping with High, Medium, Low
Discard rogue applications
Packet fragmentation assures VoIP/video latency budget
Integrates with existing environments
Mark, honor and preserve QoS based on application or QoS markings
Extensible architecture
For additional application classification
QoS troubleshooting mode
Layer-7 Monitoring and Reporting
The WAAM provides powerful monitoring and graphical reporting for full application-level visibility and cost-effective end-to-end network management.
Automatic application detection with hundreds of predefined classes. Dozens of historical and real-time reports WAN and links
Throughput, performance, acceleration
Applications and hosts
Throughput, performance, acceleration
System-wide, per link, Peer, IP subnet, application In-bound and out-bound User customizable
Complex rules available for the advanced user including nested rules, order matching, and so on
Export and print functions
Footprint for Value-Add Branch Office Features
The WAAM offers much more than just a bandwidth increase. This intelligent device delivers a branch office platform that consolidates multiple devices.
Open architecture for future enhancements

RADIUS, TACACS+, and Windows Directory
Validated in over 1,000 enterprise and service provider networks
Maximum Uptime and Reliability
The WAAMs’ resilience features and standards-based implementation guarantee unsurpassed uptime and availability.
Switch-to-wire and software watchdogs assure zero network downtime
Remote access never compromised
Out-of-band management
Network integrity preserved with standards-based implementation
IPComp tunnels
Router Transparency Mode
SCPS for TCP Acceleration
SNMP for device management
How the WAAM Works
WAAMs can be deployed in any network environment, whether it is a private line, frame relay, VPN, IP, ATM, xDSL, ISDN, wireless local loop, or satellite. WAAMs can be connected on the LAN side of the router. Some of the WAAM’s benefits can be realized with no far-end WAAM.
Configuration and Management
You can configure and monitor the WAAMOS via a user-friendly Web User Interface (WebUI). The WebUI is accessible from Microsoft Internet Explorer via the HTTP protocol or the secured HTTPS protocol. Console-based administration can be accomplished using a directly connected terminal or terminal software using a serial connection, a Telnet session, or a secured SSH-based connection. The WAAM also supports SNMP (v1/v2c/v3).
The WAAM operating system, WAAMOS, provides a wide range of management features.
Like most networking equipment, the WAAM requires some basic initial configuration in order to function. This configuration is performed locally an RS-232 console, Telnet console or browser-based management console, and includes specifying the WAAM’s IP address. The initial configuration also involves defining passwords, and the time and date at the WAAM site. The WAAM’s user-friendly Installation Wizard will guide you through the steps necessary to get your WAAM up and running.
