CONVERGENCE being equipped with IP addresses. How big could the ‘Internet of Things’ that needs to be supported be? Ericsson predicts the Internet may connect 50 billion IoT enabled devices by 2020. IT, telecom and consumer technology analyst IDC gives a far higher number – some 212 billion. Cisco predicts that by the year 2021, there will be 4.6bn global Internet users and 271 billion connected devices. 82% of all IP traffic will be video. IP Convergence is a fact, and emerging technologies will place more pressure on enterprise networks. In just a few short years, the connected office will experience an explosive growth in bandwidth demand, an evolution in wireless technology and a threefold increase in the amount of power transmitted through IP networks. The problem is, networks everywhere are already struggling with existing, and growing, bandwidth requirements. Getting the most from convergence The physical network is increasingly becoming an essential asset. For companies, institutions and operators, it’s essential to ensure this is managed and maintained long after the initial installation and investment have been delivered. During the 10-15 year lifespan of a structured cabling system, many changes will occur. Documentation has to be flawless and up-to-date to avoid downtime and errors. However, traditional methods such as spreadsheets, Visio, SharePoint and software documentation tools don’t guarantee the efficiency and 100% accuracy of the updated physical layer documentation provided by Automated Infrastructure Management (AIM). This ensures the network manager is completely aware of how the network is physically laid out and can manage and control the network remotely, improving performance in identifying errors and Mean Time to Repair. Various studies show that up 15% to 25% of network failures may be attributed to Human Error. AIM can significantly reduce this. Although convergence may initially add a degree of complexity for IT departments, by introducing a well- specified AIM system, things can actually become easier. 35 Three interrelated market drivers pushing new technology Wireless devices and new wireless standards require more, significantly faster Wireless Access Points (WAPs). A new standard in development – IEEE 802.3ax – expected to reach the market in 2020, will probably allow for a fourfold increase over the current standard of IEEE 802.11ac of up to 27 Gbps when fully rolled out. However, faster WAPs mean shorter reach and the need for faster uplink ports. This leads to the second driver: increased bandwidth. Wireless bandwidth consumption has already driven wireless access point speeds beyond 1 Gbps and will probably move beyond 5G by 2019. In response, the IEEE started a new technology initiative to enable 2.5G and 5G transmission over Cat 6. That may not be enough as 10G uplink ports have already arrived. Bandwidth-hungry applications such as WAPs and HD Video require Cat 6A (10G). Eventually, even 25G may be needed requiring Cat 7A. The third driver is next-generation of PoE. A new generation of PoE technology will allow a threefold increase in the amount of power transmitted through IP networks (up to 90W). IP networks will be able to connect and power increasing types of devices such as digital signage and TV monitors. www.networkseuropemagazine.com
