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.
N OTE – 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:
N OTE – 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.
