Simulation of TCP Variants over a High Bandwidth-Delay Product (BDP) Network | NS3 Project 8

Simulation of TCP Variants over a High Bandwidth-Delay Product (BDP) Network 1. Theory and Concept Write-up Objective: To simulate and analyse the behaviour of different Transmission Control Protocol (TCP) variants over a Long Fat Network (LFN) characterised by a high Bandwidth-Delay Product (BDP). Concept: A Long Fat Network (LFN) is a network that has both a high bandwidth (capacity) and a high latency (delay). Examples of such networks include satellite links or long-distance optical fibre connections. The "thickness" of the network pipe is massive, meaning it can hold a huge amount of unacknowledged data in transit at any given time. Standard TCP variants, such as TCP NewReno, struggle to operate efficiently on these networks. Because of the high delay, acknowledgements (ACKs) take a long time to return to the sender. As a result, standard TCP increases its Congestion Window (cwnd) too slowly, failing to utilise the massive available bandwidth. To solve this, adv...

Simulation of a large enterprise network with RIP and generate routing trace metrics | NS3 Project 7

Simulate a large enterprise network (40 nodes) with RIP and generate routing trace metrics Prompt : Prompt (Claude): You are an expert in ns-3 simulation and network protocol analysis. i need a complete, error-free, fully functional NS-3 C++ program for the following experiment: Title: RIP routing overhead analysis in a large enterprise network Objective: to simulate a large enterprise network (minimum 40 nodes) using the rip routing protocol and analyze routing overhead using trace metrics. strict requirements (non-negotiable): Output requirements: The program must generate: netanim animation file: filename: rip_overhead.xml must show all nodes clearly arranged (grid layout) must show packet flow trace file: ascii trace (.tr file) enable using asciitracehelper data files for graphs (.dat): overhead.dat for routing overhead vs time txrate.dat for packet transmission rate vs time   Network topology:   minimum 40 nodes (pre...
