Student NumberTask 11. Network Cabling optionsThe LAN cabling options is recommended for the building society. Many kinds of cables and connectors are applicable in the LANs. This however depends on the network needs in addition to the Ethernet type and media type. LAN Physical LayerThe recommended LAN technology is Ethernet. There are four types of Ethernet that can be used: 10 Gigabit Ethernet (802.3ae), Fast Ethernet (802.3u), Gigabit Ethernet over Fibre (802.3z) and Gigabit Ethernet over UTP (802.3ab). The cabling features of the LAN are found at Layer 1 of the Open System Interconnection (OSI) model.

Ethernet in the building societyIn today’s installations, the costs of infrastructure for adapters and cabling are relatively high. Still, selecting the right Ethernet connectivity offers the required speed for the network components while simultaneously controlling costs. Generally, Ethernet technologies can be used in the building society’s network in many ways: At the access layer, Ethernet speed of upto10 Mbps may be employed as it offers satisfactory performance for users. Additionally, Fast Ethernet of 100-Mbps may be employed for serves that consume high-bandwidth-consuming (Cisco Networking Academy 2013). To connect the network devices and the access layer, it is recommended that Gigabit Ethernet be used.

It can support the aggregate traffic from each Ethernet segment on the access link. Gigabit Ethernet may as well be used in connecting the enterprise’s servers as it improves the performance of client-server across the building network by preventing possible blockages at the server. Still, combining Fast Ethernet and Gigabit Ethernet will create an effective solution as it also avoids slow (Joshi et al 2001). Figure 1: Internal network topology for an office of the building societyFor purposes of linking the core and the distribution layer, it is recommended that Gigabit Ethernet be employed as the building society’s network model can support dual link between the core switch and each distribution layer.

It also provided possibilities for load balancing the cumulative traffic from various access switches across the connections. At the backbone and the switches, Gigabit Ethernet will again need to be used. At this rate, the building society fastest affordable media should be implemented between backbone switches. The table below provides an outline of the recommendations for deploying Ethernet. Requirements for Ethernet Connector and MediaThe specifications for cable and connector applied in supporting implementation of Ethernet are originate from the standards recommended by the Telecommunications Industry Alliance (EIA/TIA).

The classes of cabling recommended for Ethernet also originate from the EIA/TIA-568 (SP-2840) standards for Commercial Buildings. Accordingly, for the UTP cable, the EIA/TIA recommends an RJ-45 connector. Connection MediaThere are a range of connection media applicable for the Ethernet LAN operation. As indicated in the table below, there are varied types of connections, such as attachment unit interface (AUI), gigabit and RJ-45.

Each of this can be used in implementing the physical layer. The RJ-45 connector will be applied in the present case scenario. A Gigabit Interface Converter (GBIC) input/output device will be plugged into the Gigabit Ethernet port. Its key benefit in the case of the building society is that it is interchangeable, hence allowing the users adequate flexibility when deploying other 1000BASE-X technology without the necessity to adjust the physical interface on the switch or router. It is appropriate for the case of the building society as it is compatible with the connectors.

Mainly, the GBIC sufficiently supports UTP (copper) and fibre-optic media for transmitting Gigabit Ethernet.
