(including external rogue switches) from entering the network. In addition we will be implementing the spanning tree protocol to eliminate any layer 2 loops and ultimately causing a network storm. First I’d like to begin by going into detail about the VTP (VLAN Trunking Protocol) IEEE 802.1q. I will initially enable all the VLANs on the only designated VTP server mode, and then configure the trunking protocol 802.1q between the switches allowing all the VLANs on that trunk. All the other switches will
Multicast Tree Algorithm in ATM Network Environment Overview: The use of optical fiber has tremendously increased network bandwidth. The data used in video-on-demand (VOD), distant learning, distant diagnosis, video conferences, and many other applications have popped up one after another in recent years. They all require that the same data be sent to multiple recipients. This operation is called multicasting. Introduction: Asynchronous Transfer Mode (ATM) is the mostly implemented in high speed
Tree definitions If you already know what a binary tree is, but not a general tree, then pay close attention, because binary trees are not just the special case of general trees with degree two. I use the definition of a tree from the textbook, but bear in mind that other definitions are possible. Definition. A tree consists of a (possible empty) set of nodes. If it is not empty, it consists of a distinguished node r called the root and zero or more non-empty subtrees T1, T2, …, Tk such that
“The Spanning Tree Protocol (STP) is an older network protocol that ensures a loop-free topology for any bridged Ethernet local area network. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.” What is the difference between a hub
ABSTRACT In this paper, we will conduct a comparison on Fast Ethernet Network Switches and Gigabit Ethernet Network Switches offered by 3COM. We will review a few specific components, as well as compare features, pricing and preferred usage. DEFINITION In order to have a greater understanding of the terminology and descriptions offered in this paper, we must first understand what a network switch is. A brief definition of a network switch is a computer networking device that connects network segments
Introduction In this modernize world, internet and network are very vital and important not only for individuals but also for companies, organization, institution, etc. Because of this, it is very important to make use of as many network devices available. We need to study more or at least to have a glimpse of information about the networking devices before we choose or start using it. There are many networking device out there that able for us to study but the chosen device for this report are hub
WAN: WAN is a computer network spanning a relatively large geographical area. WAN stands for: Wide area Network. WAN consists of more than two local area networks (LAN) LAN is also a computer network but unlike WAN it spans in a relatively small area such places as a home, school building, office building or computer laboratory. The most well-known or the most popular WAN is the internet. Unlike LAN, WAN is usually not owned by a single organisation or company but exists under distributed or collective

Network Management and Optimization Proposal This is a proposal for network management and optimization. The network has grown rapidly, and the company has not completed proper documentation and policies. This proposal includes required documentation; network monitoring, event logging, and maps; data backup; and network optimization. Documentation In order to maintain, troubleshoot, and prevent network outages, network administrators need to refer to documentation. Required documentation includes
between body sensors and the communication between the sensors with the personal server (PS). The design of this layer is critical as the sensors are battery-operated and have low bit rates thus it’s important that there is an energy-efficient MAC protocol with QoS provisioning. The connection between the sensors and PS can be wired or wireless. In wired they use MIThril and SMART to connect the sensors to the PS. MIThril is a wearable computing platform that is used to monitor a user’s physiological
qualitative risk analysis methodology that can be used to pres-screen a subject of analysis as a means to determine whether a full blown quantitative risk analysis is needed. • Spanning Tree Analysis. This can be thought of as a visual method for identifying categories of risk, as well as specific risks, using the metaphor for a tree ad its branches. This approach would be similar to a Mind Map for identifying categories and specific threats and/or vulnerabilities. NSIT 800-30, Risk Management Guide
