URL-Based Bandwidth Management Example
In this example, you will assign bandwidth based on URL paths. For URL-based server load
balancing, a user has to first define strings to monitor. Each of these strings is attached to real
servers, and any URL with the string is load balanced across the assigned servers.
NOTE – The complete procedure to configure URL-based SLB is described in Chapter 7,
“Content Intelligent Switching” of the Web OS Application Guide.
The best way to achieve URL-based bandwidth management is to assign a contract to each
defined string. This allocates a percentage of bandwidth to the string or URL containing the
string.
To configure the switch for URL-based bandwidth management, perform the following steps:
NOTE – Refer to the Web OS Command Reference, Chapter 7, for more information on how to
create a contract.
1. Define a load-balancing string for URL-based server load balancing. For example, add
the string “alteon.”
To see the URL path ID assigned for the string “alteon,” execute the cur command:
2. Allocate bandwidth for each string.
To implement this, assign a BWM contract to a defined string.
