Switching & Routing
The purpose of this paper is to provide a better understanding of switching and routing used in a network environment and familiarize the reader with various hardware and software associated with there functions. This paper will look at some switching concepts that will include store and forward switching, cut through switching, fragment free switching, and V-Lan. This paper will also cover routing concepts, along with some comparisons including routed vs. routing protocols, Classful vs. classless protocols, and distance vector vs. link state protocols.
Switching
The definition of a switch or network switch is a small device that joins multiple computers together, working on layer two of the OSI, to form a local

There are hybrid switches available today that combine both store-and-forward and cut-through switching methods. These hybrids are known as runtless or fragment-free switches. Fragment-free switches were designed to solve the late-collision problem and are primarily used in the backbone of congested networks. These hybrids check both the source and destination MAC address of a packet then make the appropriate switching to send the packet to its corresponding destination (Javvin Technologies,Inc., 2008).
VLANs
VLANs or Virtual Local Area Networks are logical local area networks that extend beyond the traditional LAN architecture. Because a VLAN is a logical entity, creating and configuring a VLAN is done completely in software. The advantages to using this type of LAN include but are not limited to the ability to conserve the network resources, to bridge geographical drawbacks, and to better manage the movement of personnel and equipment. To understand the need for VLANs you must first understand the Local Area Network (LAN). The definition of a LAN started as a group of computers that were connected in the same area, but today’s LAN is defined as a single broadcast domain. This is explained easily by looking at a large organization where each department would be on a separate LAN found behind a router or switch. With today’s expanding networks it has become important for these
