Ethernet, the dominant protocol in this area, has been around since the early 1970s \cite{ethernet}. Research has indicated that Ethernet has a number of issues as the size of networks scale up. A number of different proposals have been made replace Ethernet, notably SEATTLE \cite{seattle} and MOOSE \cite{moose1}. Due to the large numbers of hosts and data involved in performing such a simulation, and the variety of different network topologies I shall analyse, the only suitable mechanism in order to perform this evaluation is under simulation. @@ -8,7 +8,7 @@ In this paper, I aim to compare one of these proposals to Ethernet in order to p \section{Background} -% insert intro to background here +% TODO: insert intro to background here \subsection{Protocol Stack} @@ -40,6 +40,8 @@ The top layer of the protocol stack in the Internet Protcol Suite model and the \subsection{Ethernet} +% TODO: queueing needs mentioning + Ethernet is the most widely deployed and used Local Area Networking - LAN - technology currently in the market. While the physical layer of the standard has undergone a number of iterations, the data link layer protocol has remained largely stagnant due to the lack of motivation and a desire for interopability with current equipment. Ethernet was first described in a memo on May 22, 1973 at Xerox PARC by Bob Metcalfe who designed it to interconnect workstations and printers in a modern computer network. \cite[p.~125{spurgeon} It was to be a shared medium network based on the previous work by the University of Hawaii in the late 1960's with the Aloha network. \cite{abramson}. Ethernet pioneered the technology by incorporating CSMA/CD (Carrier Sense Multiple Access with Collision Detection). This allowed the original Ethernet networks to be a single shared medium network where all the computers were connected together using a single cable. Every computer on the network would recieve all the packets and, based on the header, the Ethernet controller would inform the system when a packet arrived which was for the host in question. -- 2.34.1
