    Studying the seven layers of the OSI design, a decision to be taken is that the layer three, also referred to as the network layer is the one which WAN protocols operates on. The network layer carries out regular tasks as well as pinpoints end-to-end addressing and routing datagrams (Regan, 2004). There exists a unit known as brouter that some layers incorporate which works like a router and a bridge. Routers and switches work on layers 2-4 (data link layer, network layer as well as transport layer). As mentioned earlier, on layer two of the OSI model, network layer, is the place where the addressing and routing is carried out. On the transport layer of the OSI model is the place where the flow control and mistake handling works. Lastly, on layer four the synchronizations and assemblies are completed.…

    In order to provide speed and reliability, large and enterprise-level networks today are typically constructed in multiple layers. They are the access layer, also called the network edge layer, the aggregation or distribution layer; and the network core layer. The access layer is usually a mesh of network switches, linked to other switches in the aggregation layer, which in turn is linked to the core.…

    The 7 layers can be split logically into two subgroups. Layers 7 thru 4 focus on the end to end communication of data source and destinations. Layers 3 thru 1 are provide consistent communication between the network devices. An easier way of looking at the OSI model is dividing the upper layers (7, 6, 5) from the lower layers (4, 3, 2, 1). The upper layers deal with application issues and are implemented only in software. The highest layer, the application layer, is the closest to the end user. The lower layers are responsible for the transportation of the data. The physical layer and the data link layer are implemented in hardware and software. The lowest layer, the physical layer, is closest to the physical network medium (the wires, for example) and is responsible for placing data on the medium.…

    The Network Layer is accountable for implementing a logical addressing scheme and for transporting the packets from one end to the other end. The network layer can be connectionless or it can be connection oriented. This layer is also responsible for breaking larger packets up for delivery depending on the media this is known as packet switching. These protocols include Apple talk DDP, IP, and IPX.…

    The need for more speed and capacity never goes away. Most enterprises are still rolling out 10 Gigabit Ethernet links in their networks, but already network architects and engineers are preparing for the future because data traffic never stops growing. Early adopters are testing and deploying the first generation of 40 Gigabit Ethernet (GbE) switches and routers to get a step ahead of this continuous onslaught of traffic. ―We are seeing incidental peaks of traffic nearing 10 Gbps,‖ said Jeroen van Ingen, a network engineer at the University of Twente in the Dutch city of Enschede. ―Given the traffic growth over the years, we expect to need more capacity within 12 to 24 months. That’s why we decided that new core equipment should support 40 GbE.‖ Van Ingen is not alone in predicting the need for 40 GbE and beyond. Research from the Dell’Oro Group forecasts the overall Layer 2 and Layer 3 Ethernet switch market will reach $25 billion in 2016, with 40 and 100 GbE technology approaching $3 billion in sales. Meanwhile, Infonetics Research shows sales of 40 GbE technology grew 50% in both Q1 and Q2 of this year. The expansion is largely driven by bigger data centers and the move to the cloud, according to researchers. The university recently upgraded the core of the residential portion of its campus network with two of Cisco Systems’ Catalyst 6500-E switches. Today, those core switches are interconnected…
