The router only needs to know the next-hop address; in other words, it sends the data to the next router; this next router then takes its own decision.

Each router maintains a routing table, with information about where to send IP packets. The information is stored on a per-network basis. When the router receives an IP packet, it consults the routing table, to see what is the next-hop address, and through which interface it must send the packet.

Explain the way in which packet switched networks differ is similar to circuit switched networks?

Computer networks would be packet switched whereas a phone network would be circuit switched. Obviously packet switched are going to be alot more reliable and apparantly cheaper and less harder on the environment.

As a packet traverses different networks, the source IP address will always stay the same as the original sending devices IP address unless NAT (Network Address Translation) is involved somewhere along the line.

How are endless loops of packets prevented?

A packet will not go around networks endlessly because it has a field in the header called the TTL field. This is a number that limits the number of hops or networks a packet will be forwarded to.


Differences between arp packet transmission and ip packet transmission?

an arp (address resolution protocol) comes into picture when we have the ip address of our destination but we dont know the mac address of our destination.Normally when we open a web site this is the process which takes place.IP packet transmission comes after arp when the destination mac address is obtained after arp request.so an ip packet contains both source & destination IP & mac addr.


What happen if a packet is received and the MAC address does not match the workstations MAC address?

if the MAC address is not matched, then the packet is discarded and not processed.
