NOTE: Intel Load	Typical load balancers work by balancing traffic over a Local Area
Balancer refers to either	Network (LAN) to a Web farm. The Intel® NetStructure™	7190
Intel®NetStructure™	Multi-Site Traffic Director extends this balancing to multiple sites
7180/7185 e-Commerce	over a Wide Area Network (WAN). By balancing referrals to each
Directors or the	site, the 7190 enables enterprises and Web hosting services to
Intel®NetStructure™	integrate geographically distributed content and services.
7140/7145/7170/7175	The advantages of such integration are many, including:
Traffic Directors.
	• There is increased fault tolerance and availability owing to
	redundant sites. Multiple active sites permit uninterrupted service
	in the event of a localized outage in the data network.
	• Customer response times are improved by directing users to
	uncongested sites or data centers.
	• Easy scaling of server farms can be accomplished.
	Multi-site load balancing works best in concert with Intel®	load

balancers. The 7190 also supports multi-site load balancing with sites that do not have Intel load balancers. In this case, the sites are balanced on the basis of availability, and not based on proprietary metric information.
