endpoints, could rely on the network’s common awareness of time and frequency (the “T” in “TDM”). As the journey toward Carrier Ethernet networks gathered pace, major questions arose as to how this process would be replicated on Carrier Ethernet. While some traditional GPS and overlay TDM (such as SONET and SDH) alternatives can be used to carry out the same role as traditional network nodes, they can often be expensive or risky and unreliable.
Packet networking technologies, particularly SyncE and 1588v2, hold the answer. This technology is able to sit on the network, replicating the appropriate timestamps needed by mobile and smart power applications going forward. Not only do such solutions allow critical data to be kept secure, but the ability to have complete control over them results in lower costs.
3. The critical role of the network For many years, a robust, reliant network was considered a luxury by many organisations. The move to an increasingly cloud-dependent society has transformed the network from ‘luxury to necessity’ and it is now the foundation of any critical business application. As this reliance increases, network infrastructure will continue to grow and increasingly become not only the cornerstone of business stability but also a key driver in profit growth.
As with any critical business tool, senior decision makers are looking for the best solution, at the most effective cost for deployment. Carrier Ethernet’s flexibility, scalability and reliance have made it the most ideal enterprise network solution to deal with such needs.
4. Virtualization of resources
Network resources are increasingly becoming software-based. This means they can be hosted on generic servers that are far more effective and cost efficient than the traditional ‘appliance approach’. Carrier Ethernet allows critical parts of the network ecosystem to be divorced from the router platform. This means that firewalls, load- balancers and routing engines can be more effectively ‘centralised’. The flexibility and choice this provides allows enterprises to make significant cost savings, predominantly by reducing their reliance on one vendor for all aspects of the network environment.
5. Software Defined Networks
The network is increasingly being defined by the applications it powers. Flexible, on-demand bandwidth (as well as other attributes like latency and protection levels) can be automatically requested by these applications. Unlike previous years whereby such a request (often sent manually) had to be verified by an IT manager, technology like Software Defined Networking (SDN) allows the network to not only respond accordingly (unaided and in a matter of milliseconds), but also allows it to optimise resources so it is used efficiently. As this trend increases, operators will increasingly use technology to mine the network for analytical information about usage patterns in order to respond to such demand more effectively in a timely manner.
