Q:

What is the way in which the Asynchronous Transfer Mode works?

Answer

The Asynchronous Transfer Mode or ATM is a connection technology that works by transmitting data into organized 53 bytes (small) packages through a physical environment with a high efficiency. Packing data into small cells reduces transportation delay so the speeds reached by this technology are very high; it can reach even 10 Gb per second.

Q:

What is traffic shaping?

Answer

One of the main causes of congestion is that traffic is often busy. If hosts could be made to transmit at a uniform rate, congestion would be less common. Another open loop method to help manage congestion is forcing the packet to be transmitted at a more predictable rate. This is called traffic shaping.

Q:

What is the Routing Information Protocol or RIP?

Answer

RIP is a is an interior gateway protocol that was often used in interior networks and in some degree in internet networks. It helps the router adapt to the modifications that are made in a network regarding connections. Now it become less used since more efficient protocols were implemented like OSPF or IS-IS. It is limited to a lower number of routers, a maximum of fifteen router.
