Bandwidth Management
784 Document ID: RDWR-ALOS-V2900_AG1302
• Alteon allocates bandwidth based on certain strings in the incoming URL request. For example, if
a Web site has 10 Mbps of bandwidth, the site manager can allocate 1 Mbps of bandwidth for
static HTML content, 3 Mbps of bandwidth for graphic content and 4 Mbps of bandwidth for
dynamic transactions, such as URLs with cgi-bin requests and .asp requests.
• Ability to prioritize transactions or applications.
• By allocating bandwidth, Alteon can guarantee that certain applications and transactions get
better response time.
• Ability to allocate a certain amount of bandwidth for requests that can be cached.
As shown in Figure 132 - URL-Based SLB with Bandwidth Management, page 784
, users are able to
allocate a certain percentage of bandwidth for Web cache requests by using the URL parsing and
bandwidth management feature.
Figure 132: URL-Based SLB with Bandwidth Management
This example assumes you have configured URL-based SLB and the layer 7 strings as described in
Content-Intelligent Server Load Balancing, page 219. For URL-based SLB, 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. 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.
1. Configure Content-Intelligent Server Load Balancing, page 219
.
2. Configure BWM policies with the desired bandwidth limits. In this example, four policies are
configured, as illustrated in Figure 132 - URL-Based SLB with Bandwidth Management, page
784.
