Briefly explain the roles of transport mapper, message dispatcher and PDU dispatcher in SNMPv3 architecture. Briefly explain the role of a Proxy server in web based
Bridges are networking devices that can connect 2 local area networks (LAN). A bridge can learn all of the MAC addresses on the network, and this is done during the bridges data gathering phase. Basically a bridge will receive the data and analyze the address. The bridge will then pass the data on to the correct address. The ports on a bridge are in and out, but they are smart ports with the ability to locate the address on the network.…
This week’s assignment is to describe various event categories and event based transactions that are used by the Network Management System. It would be impossible to categorize all potential causes for alarms in all existing network systems however, understanding some common alerts and categories is essential for any network manager.…
The core of a coaxial cable carries the electronic signals that make up the data. This wire core can be either solid or stranded. If the core is solid, it is usually copper.…

For phase 3 discussion board we are ask to describe and compare the Open Systems Interconnection (OSI) model with another network model. For this assignment I will use the Transmission Control Protocol / Internet Protocol (TCP/IP) model. These models divide the communication process of the network into smaller parts. This helps with design, development, and troubling shooting. The OSI model has 7 layers- 1) Physical, 2) Data Link, 3) Network, 4) Transport, 5) Session, 6) Presentation, 7) Application. The TCP/IP model has 4 layers.…

IEEE 802.15 deals with the subject of Wireless personal area networks (WPANs) which includes standards for Bluetooth, co-existence of WPANs with other wireless devices, high-rate and low-rate WPANs, and mesh networking.…
In order to understand network management effectiveness, factors called metrics have to be put into place that will impact the management bottom line. These metrics have been put into place in order to further gauge, not only the network effectiveness, but also the efficiency of the network. This paper will attempt to address some of these various metrics that are used to gauge network effectiveness and efficiency in meeting organizational goals.…
Cisco uses the International Organization for Standardization network management model which defines five functional areas of Network management. The model consists of Fault Management, Configuration Management, Performance Management, Security Management, and Accounting Management. In this paper we will cover the models five functional areas.…

The reliance by companies of all sizes on information technology creates strong demand for system and network administration jobs. Information System majors will increasingly find themselves with opportunities and responsibilities in these areas. However, teaching operating systems and networking to information systems major presents many challenges. We have developed a model for teaching these topics to information systems majors in the context of operating system and network administration. This paper describes our model, the lecture materials used, and a novel lab configuration.…
1. An enterprise campus LAN uses wired UTP Ethernet and wireless 802.11 LANs at the edge of the LAN. Looking at a particular floor in a particular building, all the devices connect to either a single Ethernet switch or single wireless access point, both of which sit in a wiring closet in the middle of the space. Which of the following is true about the distance limitations in this LAN?…
