ADVERTISEMENT QED What are the pros and cons of multi-manufacturer integrated solutions? Quality Essential Distribution’s Steve Constantine explores the thorny issue of tailored networks and discovers that, from devices to integration, success lies in the initial design. I n an industry full of acronyms and ever changing standards, designing networks to suit specific customer requirements can quickly lead to confusion and frustration. To ensure all bases are covered and that all network devices will integrate effectively, the first and most important step in creating a successful network is the application design. When networks are designed with thought and consideration, the high performance that is delivered is the seal that the customer has spent wisely. Some of the most common errors in network design and deployment is the lack of understanding of what the network needs to be capable of and, more importantly, how the system will actually be used. This can depend on what is being transmitted, i.e. data, VoIP, surveillance or a mixture. But it can also depend on the following considerations: Beating bottlenecks It’s easy to assume that your network will cater for all types of traffic, but failing to consider bottlenecks in throughput can cause serious performance issues. These bottlenecks can be caused by hardware limitations or by using a variety of infrastructure transmission types such as fibre, copper, wireless or satellite communications. One of the most common causes of bottlenecks is misunderstanding aggregate throughputs – a simple mistake to make without reading the technical specifications of every product. That’s because manufacturers often mix up their aggregate and directiona l throughputs stating, for example, that a product is a gigabit port, by which they mean it has the ability to allow a gigabit of data to pass through it. Although technically correct, it’s also confusing because it translates to a maximum of 1 gigabit in total, giving potentially 500mb in each direction. An alternative manufacturer might offer double the data throughput and still market it as a gigabit port. 32 QED spread.indd 32 01/11/2016 14:43
