Logical vs. Physical Network Design The typical Top-Down approach to network design uses a systematic method to plan‚ design‚ and implement a new network. Generally‚ the Top-Down methodology involves analysis of the business requirements and goals‚ development of the logical design based on such goals‚ development of the physical design‚ and a phase for testing‚ optimizing‚ and documenting the network design. This paper focuses on the activities performed to create a logical design of a network

Welcome back to the Lab Programme! In this lab‚ we’ll investigate the behavior of TCP in detail. We’ll do so by analyzing a trace of the TCP segments sent and received in transferring a 150KB file (containing the text of Lewis Carrol’ s Alice’s Adventures in Wonderland) from your computer to a remote server. We’ll study TCP’s use of sequence and acknowledgement numbers for providing reliable data transfer; we’ll see TCP’s congestion control algorithm – slow start and congestion avoidance – in

Network Design: Logical and Physical Design In networking terminology‚ the term network topology refers to the entire structure of the network. There are two primary parts to the topology definition: the physical design‚ which is the actual layout of the wire (media)‚ and the logical design‚ which defines how the media is accessed by the hosts. The physical designs that are commonly used in networks are the Bus‚ Ring‚ Star‚ Extended Star‚ Hierarchical‚ and Mesh. A bus topology uses a single
