NT 2640 Final Study Guide

A: OSI stands for Open System Interconnection. The main aim of the OSI layer is to implement protocols of a networking framework.

The Router protocols implemented will be a OSPF which stands for (open shortest path first). Because of the large network being introduced this protocol will be the most useful. This protocol operates on Internal Gateway Protocols by routing the most direct path and using the bandwidth most optimally. This not only reduces the use of

AODV are utilized, instead of broadcasting data packets, S start off a route discovery protocol that requires broadcasting smaller Route Request

The OSI Model is a model is used to define how data is theoretically passed on a network. Each layer is responsible and has its own duties for a network. The name of layer 3 in the OSI is the Network Layer. This layer is responsible for creating the paths for the transmission of data across the network. This layer provides routing and switching capabilities, as well as, internetworking, congestion control, and packet sequencing (Beal, 1999).

A communications protocol characterizes the guidelines for sending pieces of information starting with one hub in a system then onto the next hub. Conventions are regularly characterized in a layered way and give all or part of the administrations indicated by a layer of the OSI reference show. A convention characterizes the operation of the convention and may likewise propose how the convention ought to be actualized. It comprises of three sections:

| Given a network topology of two or more routers and an IPv4 addressing scheme, implement static routing and confirm layer 3 connectivity.

contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.

The OSI is divided into two groups, upper layers are 7-5 which handle application issues and are only implemented in software. The lower layers are 4-1 deals with issues caused by data transport. As stated above, the hospital’s network is segmented into two; layer 2, the data link layer, allows the bridge to connect multiple networks. This layer allows data to transmit between the networks which can possibly detect and correct any errors that may happen in the Layer 1, Physical Layer. When the hospital is transferring data between the systems, it takes many steps to complete. The data passes an application on a

The Open Systems Interconnection (OSI) reference model is essential to the world of computer networking. The model was created in 1977 by the International Standards Committee, in response to a difficulty that was facing computer networkers at the time (Shelly, Cashman, and Serwatka 142). In order to understand the difficulty, one must first realize that computer networks consist of computer hardware, the software that is to be used in conjunction with this hardware, and the medium (such as wiring or cabling) that will interconnect the computing devices that are in the network. The computer networker’s job is to determine which hardware, software, and medium types will create the network that will

Brocade is fully invested in making SDN completely modular to deliver New IP networks based on an open ecosystem. The Brocade SDN Controller is continuously built from the OpenDaylight code, with a virtuous cycle of contributions back to the OpenDaylight community. Physical and virtual networks from multiple vendors can be managed within the Brocade SDN Controller, and organizations can gradually introduce ever-larger portions of their existing networks into the controller domain with single-source technical support for the entire

As this demand for dynamic and unpredictable data grows, more and more devices have to be added to existing networks and configured accordingly. The need of the hour is to regulate networks centrally and as a whole rather than configure individual network devices and gain more control to achieve flexibility in existing networks.

Key tools utilized, variable length subnet masking and route summarization are explained as well. Here choosing the appropriate routing protocol is equally critical for a successful design. To implement different masks for the same major network it is necessary to have a routing protocol that supports VLSM. Such routing protocols are called classless routing protocols. They carry the mask information along with the route advertisements therefore allowing for the support of more than one mask.

OSPF is an IGP (Internal Gateway Protocol) designed for small to mid-sized networks and for fast convergence. OSPF operates on an area based structure wherein multiple small areas connect to a central area through which all inter-area data passes, called Area 0. On the surface, OSPF is extremely simple as it pertains to straightforward, relatively small networks. There is, however, a battery of complex commands used for micromanagement, security, manual data flow regulation, and virtual connections to Area 0. This means that if you plan on creating an OSPF network, you will spend much more time planning and configuring larger and more intricate networks, especially compared to EIGRP and RIP.
