Cisco Systems 7326 Manual De Usuario

The operation of the WAE is dependent on the software application that is 
installed on it. This section describes WAAS, ACNS and WAFS software:

With WAAS software installed, the WAE appliance functions as either a WAAS 
Central Manager or a WAAS Application Acceleration Engine. The WAAS 
Central Manager provides a graphical user interface to monitor and configure all 
Acceleration Engines. The WAAS Acceleration Engine is deployed in remote 
branch offices and in the data center to accelerate TCP applications that access 
data across the network. 

The Application Acceleration Engine functionality operates at different levels 
based on the software licenses purchased. WAAS 4.x, software offers the WAAS 
Transport License or the WAAS Enterprise License options. 

Cisco WAAS software helps enterprises meet the following objectives:

Provide branch office employees with LAN-like access to information and 
applications across a geographically distributed network. 

Migrate application and file servers from branch offices into centrally 
managed data centers. 

Minimize unnecessary WAN bandwidth consumption through the use of 
advanced compression algorithms. 

Provide print services to branch office users. Cisco WAAS allows you to 
configure a WAE as a print server so you do not need to deploy a dedicated 
system to fulfill print requests. 

Improve application performance over the WAN by addressing the following 
common issues: 

Low data rates (constrained bandwidth) 

Slow delivery of frames (high network latency) 

Higher rates of packet loss (low reliability)
