Server Load Balancing
8. Configure an HTTP Layer7 content switching rule in the HTTP virtual service to match Class4
(with URL my-site.com and mobile-browsers), and perform HTTP redirection to
http://mobile.my-site.com.
9. Configure an HTTP Layer7 content switching rule in the HTTP virtual service to match Class5
(with URL mobile.my-site.com), and perform load balancing using Server Group2.
XML/SOAP-Based Server Load Balancing
With the evolution of Web applications, much of HTTP traffic is based on SOAP messages or other
XML formatted data transfer. Alteon can perform content switching based on specific XML tag
attributes or tag values. The following is a SOAP message written in XML format and sent over HTTP
protocol:
Example XML/SOAP-Based Message
POST /InStock HTTP/1.1
Host: www.example.org
Content-Type: application/soap+xml; charset=utf-8
Content-Length: nnn
<?xml version="1.0"?>
<soap:Envelope
xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">
<soap:Body xmlns:m="http://www.example.org/stock">
<m:GetStockPrice
<m:StockName>IBM</m:StockName>
</m:GetStockPrice>
</soap:Body>
</soap:Envelope>
In this message, Alteon performs content switching based on a tag attribute such as the tag
GetStockPrice with the attribute StockEx, which has the value NASDAQ. Alternatively, Alteon can
perform content switching based on a tag value like the tag StockName with the value IBM.
To configure XML-based load balancing
1. Before you can configure XML-based load balancing, ensure that Alteon is configured for basic
SLB with the following tasks:
— Assign an IP address to each of the real servers in the server pool.
— Define an IP interface.
— Define each real server.
— Assign servers to real server groups.
— Define virtual servers and services.
For information on how to configure your network for SLB, see
Works, page 166.
