The DSLAM de-multiplexes the data streams and converts them into ATM data, which are then distributed to the ISPs.

What is used by BGP to determine the best path to a destination?

How does BGP do load balancing?

BGP load balancing through route recursion The matching route with the direct next hop is called the recursive route. The process of finding a recursive route is route recursion. If multiple recursive routes to the same destination are load balanced, BGP generates the same number of next hops to forward packets.

How does a router choose the best route?

A primary function of a router is to determine the best path to use to send packets. To determine the best path, the router searches its routing table for a network address that matches the destination IP address of the packet.

How does BGP choose routes?

BGP tries to narrow its path selection down to one best path; it does not load balance by default. To do so, it examines the path attributes of any loop-free, synchronized (if synchronization is enabled) routes with a reachable next-hop in the following order: Choose the route with the highest weight.

Does VDSL require a phone line?
