What is WAN aggregation?

Wide area network (WAN) aggregation, also referred to as multilink aggregation, and link load balancing, focuses on the Internet facing connections of a business. WAN aggregation can be deployed as a single-sided, or two-sided solution. WAN aggregation improves application performance and predictability when facing network congestion. It also improves application reliability by avoiding network failures when a link goes down, or a router fails. WAN aggregation is generally more affordable and easier to manage than Border Gateway Protocol (BGP), making it a good option for small businesses. It is important to note, even though WAN aggregation is less expensive than BGP; it is still highly reliable, and provides optimum performance for any size business.
