OSI MODEL Virtually all networks in use today are based in some fashion on the Open Systems Interconnection (OSI) standard. OSI was developed in 1984 by the International Organization for Standardization (ISO)‚ a global federation of national standards organizations representing approximately 130 Countries. The ISO created the OSI to make the IOS more efficient. Where‚ ISO stands for International Organization for Standardization. OSI stands for Open System Interconnection. IOS stands for

LAN by using a router. The disadvantage of this method is routers usually take more time to process incoming data compared to a bridge or a switch. More importantly‚ the formation of broadcast domains depends on the physical connection of the devices in the network. Virtual Local Area Networks (VLAN’s) were developed as an alternative solution to using routers to contain broadcast traffic. VLAN’s also allow broadcast domains to be defined without using routers.

Network Management Systems (NMS) Network Management System is defined as the collection of tools that assist human network managers in planning‚ configuring‚ controlling and monitoring the computer networks. It covers all the activities and safety measures needed to ensure the effective and efficient use of the resources to be managed. Thus‚ a Network Management System has to address different functional areas of a computer network and has to fulfill the requirements of the users in these areas

to managing a small business network. Lastly I will talk about what I recommend for a small business network. To start the body off‚ I will be explaining what equipment is needed to start a small business network. First we have our routers and switches. Routers perform many functions‚ one of which is serving as a firewall. Computers have tens of thousands of ports‚ or "doors" as this essay will refer to them as. Without a firewall‚ all the doors on the computer are unlocked and available for anyone

1. Introduction. Open flow is a new kind of protocol designed to run on Switches and routers. It’s built on a separated base between the forwarding plane and control plane joined through a secure channel. The controller‚ within the control plane‚ handles the management of the tables and traffic flow through updating‚ deleting and adding of flows while the forwarding plane handles traffic forwarding. Open Flow is designed in a way that the devices can separate research traffic from the normal
