Link Load Balancing
Enterprise customers no longer have to rely on low-risk, high-cost ISP services to provide link reliability. They can aggregate bandwidth of multiple links from different ISPs, which not only reduce cost but also improve overall reliability and availability of access. Because all the links are utilized simultaneously, failure risk associated with any one link is eliminated. Losing a link merely results in reduced available bandwidth and not in the loss of access availability and performance. Applications are fully transparent to link failures and restoration, and continue operating, although with changed bandwidth capacity.
