CSE 80N Lecture Notes - Lecture 18: Fault Tolerance, Network Address Translation, Mac Address
Document Summary
Cmpe 80n-lecture 18 notes-network address translation (nat) and routers (today was a short lecture) Applies mask to incoming ip address and becomes destination ip; then next hop for the packet is written in the same row. Nat device that deals with the transport layer (port) and the network (address) Routers have unique ip addresses on each interface. Attach to 2 or more physical networks. Hosts know little about structure of internet. There are 2 entries in forwarding routers. Internet gets information in a much less direct fashion. Information goes from one place to another in something called a packet. A large image can get broken down into smaller packets and bits to travel and reach the. Packets are reassembled right before delivered to computer by all the routers in between the server and destination/client. Network is considered information/packets to be sent.
