This networking fundamentals book describes how a Junos device is able to ahead a packet between networks using either static routes or any of 5 widespread routing protocols: RIP, OSPF, IS-IS, iBGP, and eBGP. (The reason the packets do get put in the correct order is due to TCP, the connection-oriented protocol that retains track of the packet sequence in a message.) Within the Open Techniques Interconnection ( OSI ) communication model, IP is in layer three , the Networking Layer.
IP is the first protocol within the Internet Layer of the Internet Protocol Suite, which is a set of communications protocols consisting of 4 abstraction layers: hyperlink layer (lowest), Web layer, transport layer and application layer (highest).
These routes and times are additionally determined by the Postal System, which is the IP. However, the Postal System (within the transport and utility layers) puts all of the pieces back together before delivery to the receiver (vacation spot host).
2 The paper’s authors, Vint Cerf and Bob Kahn , described an internetworking protocol for sharing resources utilizing packet switching amongst network nodes A central management element of this mannequin was the “Transmission Management Program” that incorporated both connection-oriented hyperlinks and datagram services between hosts.
IEN 2 (Feedback on Internet Protocol and TCP), dated August 1977 describes the need to separate the TCP and Web Protocol functionalities (which had been beforehand combined.) It proposes the primary version of the IP header, using zero for the model discipline.
