How to Differentiate WAN Optimization Products
How to differentiate WAN optimization products
WAN link controllers, WAN optimization controllers and WAN geographical load balancers are all WAN optimization products. Let's differentiate between the three of them:
1. WAN link controllers: intelligently distribute user traffic among multiple, diverse WAN and ISP links. Advanced products include WAN and ISP link aggregation, automated inbound and outbound load balancing and failover, site-to-site channel bonding, multisite failover, traffic shaping, and built-in VPN and firewall technology.
2. WAN optimization controllers: accelerate applications with caching, compression, wide area file services (WAFS), protocol optimization, quality of service (QOS) and traffic shaping, and other content and application-specific acceleration methods.
3. WAN geographical load balancers: utilize global redirection technologies and health checking to keep users connected. They distribute traffic based on various parameters such as geography, round trip time, site availability and hops.
