46 CONVERGED INFRASTRUCTURE Converged applications (CA) scoring helps define cabling requirements now and in the future. Using highly realistic scenarios, it shows how network infrastructure will perform against future demand and converging applications. more intelligent functionality, unlimited by the speed of network connections. To provide multiple users with a seamless experience, speeds of one Gbps and higher are necessary. Wireless bandwidth consumption has already driven Wireless Access Point (WAP) speeds beyond 1Gbps, making 1Gbps Ethernet backbone a bottleneck. The first WAPs supporting the IEEE803.11ac standard are already available, enabling wireless transmission of up to 1.3Gbps. WAP speeds will probably move beyond 5Gbps by 2019. Deploying high performance cabling networks capable of supporting the 2.5, 5, and 10Gbps data rates appears to be the best way of ensuring that the explosion in ‘intelligent’ devices can be supported well into the future. However, all these intelligent devices also need to be powered – which also adds the need to simultaneously support growth in high power PoE. Photo William Beaucardet evolution in wireless technology, and a threefold increase in the amount of power transmitted through IP networks. Infrastructure design and technology will have to accommodate these future demands. This means that simply checking whether components have the right bandwidth specifications will no longer suffice, as the more complex requirements of a converged environment need to be taken into account. Smart choices need to be made to support current network requirements and offer enough scope for later expansion without under or overspecifying. Carefully considering network requirements today will definitely save a great deal of replacement cabling and components in the (near) future. There’s no one size fits all answer, but we propose answering three sets of questions to arrive at a practical answer: 1. 2. 3. Consequences for infrastructure The connected world will soon experience a convergence driven, explosive growth in bandwidth demand, an www.networkseuropemagazine.com People and devices: what type and level of performance do you require? Not just today, but also in the future. Building conditions: which specific conditions exist in your building(s)? Which distances need to be bridged? Are there specific requirements with regard to functionality or practical limitations? Network flexibility: how flexible does your network need to be to accommodate probable future usage requirements? How do you ensure this is the case?
