Question 1. The trans air spirit level and net income horizontal surface distributively have their own form of addressing. Comp atomic outcome 18 and contrast these forms and how they stir to the functions of the social classs. The transport layer and network layer both occasion encapsulation and headers to apply addresses to Protocol data Units. The transport layer addresses the information by assigning stock and destination port amount to the data units - segments through infection control communications protocol or UDP protocols. The network layer assigns origination and destination IP addresses to its data units - packets using IP protocols. twain the port total and IP addresses atomic number 18 locate in the datagram header. Where the IP addresses ar unique server identifiers and argon the network addresses of the source and destination hosts, the port numbers are also unique identifiers, but of the performance or do the data came from and where it i s heading to. The main functions of the transport layer are conversation multiplexing, segmentation and reassembly and reliability, predominantly delivered by the transmission control protocol protocol. Port addressing allows different application or service segments to trigger off betwixt hosts on the same network as the port address will ensure that the segment is delivered accurately and reliably.
transmission control protocol also introduces error reporting as part of its reliability, ensuring that if data is lost then it is resent. Due to the extra functions of transmission control protocol, there are excess overheads in the header that consume bandwidth, slowing the figure out d own. The network layer has one specific fun! ction, to communicate packets between end devices. It does so using the unique IP addresses, by transmitting the data through routers until it reaches its destination. This communication is un accredited as IP has no error reporting and is a best-effort protocol. IP addressing has low overheads to enable fast communication. To create a good and accurate form of addressing, the combination of TCP and IP protocols in the transport and network layer work well together. Where TCP is...If you want to get a full essay, order it on our website: OrderEssay.net
