Modes of Operation
There are three modes of operation for the deflation and inflation compression processes:
n Static Compression
For static compression, a predefined Huffman code is used that may not be ideal for the block in question,
but it usually achieves acceptable compression. The advantage of static compression is its speed of
execution.
n Dynamic Compression
The advantage of dynamic compression is a higher compression ratio. However, dynamic compression is
slower than static compression, as it requires two passes to complete the process.
n No Compression
You can use no compression for data such as an embedded image file that might already be in a
compressed format. Such data does not compress well, and may even increase in size.
For details on configuring this feature using the Smart Config WebUI, see WAN Configuration on page 251.
Interface Bandwidth Contracts
OAW-40xx Seriesswitches have the ability to classify and identify applications on the network. If a OAW-40xx
Seriesswitch is configured as a branch office switch, you can create bandwidth contracts to limit traffic for
individual applications (or categories of applications) either sent from or received by a selected interface. There
are two basic models for using this feature.
n Limiting lower-priority traffic: If there is a lower-priority application or application type that you want to
limit, apply a bandwidth contract just to that application, and allow all other application traffic to pass
without any limits.
