Question

Explain how it is possible for a sequence of packets transmitted through a wide area network to arrive at their destination in an order that differs from that in which they were sent. Why can’t this happen in a local network?)

Answer 1

Answer:

- Different route paths, due to dynamic routing in WAN.

- Local area networks have one or very few paths to destination and does not require dynamic routing.

Explanation:

A wide area network is a network that covers a large geographical area. It goes beyond the private local area network, with more routing paths and network intermediate devices. The router is an essential tool for routing packets between devices. It requires a routing path, learnt statically or dynamically to work.

There are mainly two types of route paths, they are, static routes and dynamic routes.

The dynamic routes are used mainly in WAN. Sometimes, there can be multiple path to a destination, the router determines the best path to send the packets. It sends the sequenced packets through all available path and they arrive at the destination depending on the path used, the packets arrive in an out -of-order fashion in the destination and a rearranged.
