For network operators running multi-homed environments, data centers, or ISP networks, raw BGP leaves significant performance on the table. BGP traffic engineering — through route maps, communities, MED manipulation, and external controllers — allows you to optimize inbound and outbound traffic flows, reduce latency, balance load across transit providers, and cut bandwidth costs.</p>
