Berkeley ELENG 122 - Midterm Review EE 122. But you have to make sure they are executable. You dont need to type them or paste them. Yuanfeng Wen is student from US Berkeley. ee122 flow control for project 2 Amit Matani amitmatani at Wed Dec 5 22:20. In ns2 we have implemented the TCP-Reno algorithm which is efficient and easier algorithm than other algorithms. Each of Awk scripts provided for Project 2 has its own executable file. They are each attached to a multiplexer using links of capacity greater than p. Yilei Fu and Lihang Gong are concurrent enrollment student in UC Berkeley from Harbin Institute of Technology, China. EE122, Spring 99, Midterm 1 EE122 Midterm Exam UC Berkeley, Spring 1999 Problem 1: (10 points) (a)(1) briefly define time-division multiplexing (TDM) and statistical multiplexing (b)(2) assume 4 data sources each have a peak rate p and mean rate m. Our programming language is Python (3.5.2), 64bit. We cannot possibly finish this project if we did not receive Professor Shyam Parekh’s project reference, and we are grateful for his wonderful course this semester. We raise an overview of several future perspectives, like combining Fat-Tree structure and BCube structure. Then, we found the Fat-Tree structure also have some drawbacks, which impelled us to find more new structures and new algorithms. Also we applied flow classification and flow rearrangement on this data center topology. Catalog Description: This course focuses on the fundamentals of the wired and wireless communication networks. Ns2 was Developed by UC Berkeley and also is currently maintained by usc. Your original plan was to employ the great millennium cluster, but after Jedi Arnold depleted UC’s mineral reserves the cluster is under a constant risk of being shut down. In our teamwork, we simulated a special data center topology: Fat-Tree and applied its routing algorithm. EE122 Project 1 Fall 2010 Version 0.4 Part A due at 11:50pm on Monday, OctoPart B due at 11:50pm on Wednesday, Octo. The network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Overview In this project, you will implement a basic firewall running at end hosts. Today’s data centers may contain tens of thousands of computers with significant aggregate bandwidth requirements. To validate that the simulation works accurately, the output trace file of NS2 after simulation is compared with the traffic generated at the destinations of the production network.EE122Project Topic: Commodity Data Center Network Arch ![]() This traffic test file is then used by the NS2 traffic agents in the simulated network model representing the real production network. ee122 Project 2 Partner apolloellis at apolloellis at Mon Nov 12 20:49. ![]() Analyzed the performance of 5 node network when the packet is drop down by graphical method also called as Xgraph when rate parameter is in mb and also analyzed the performance of same network by changing the value of rate parameter at same time so no packets would drop down at same time and also analyzed the performance by Xgraph method.In this work, a modified sniffer program was used to capture real traffic data from a production network and output to a traffic text file. We also simulate the design of 5 node wired network scenario, its packet drop rate analysis through TCP protocol using NS2 as a simulator. The aim of this paper is to demonstrate how traffic agents in NS2 simulator are used to generate different types of traffic based on real traffic network. Normally the traffic in NS2 is generated from the traffic agents such as TCP and UDP agents whose parameters are based on certain statistical distribution. Wired networks can also be used as part of other wired and wireless networks. Ethernet is the fastest wired network protocol, with connection speeds of 10 megabits per second (Mbps) to 100 Mbps or higher.

One of the challenges in NS2 modeling is to seamlessly integrate real world traffic data into the NS2 network model. There has been substantial interest from researchers in the development and contribution of modules in NS2.
