Border Gateway Protocol (BGP4) for best case routing. The BGP4 protocol is a standard that allows for the routing of packets of information sent out from our network. Each packet of information is evaluated and sent over the best route possible. Because of our redundant network architecture, packets may be sent via alternative routes even if they are being delivered to the same end user. Should one of our providers fail, packets leaving our network are automatically redirected through another route via a different provider.
