The veins of the enterprise: What’s shaping Carrier Ethernet?
Impeccable transport links are crucial to the world’s economic powerhouses. From The United States to Japan, a robust network of roads and railways enables the provision of services a strong economy requires, pumping money into every corner of the nation. In addition to driving economic growth, these ‘veins’ also carry critical services like those for the medical and defence industries. By John Hawkins, Senior Product Line Manager, Ciena.
MUCH LIKE TRANSPORT SYSTEMS are the lifeblood of a nation, today’s enterprise networks are responsible for almost every day- to-day business process, from sending emails to safely transmitting highly sensitive financial transactions. Carrier Ethernet increasingly sits at the heart of the network, much like the infrastructure that makes up a country’s transport system.
Thanks to its ubiquitous nature and ability to act as a catalyst for different network technologies and services, Carrier Ethernet’s popularity is growing rapidly. With this growth expected to continue over the coming months and years, John Hawkins, senior product line manager at Ciena, looks at the top five industry drivers that are shaping the future evolution of Carrier Ethernet.
1. The evolution away from Time-division multiplexing (TDM) based services
First developed in the late 1800s TDM based services were, for generations, the standard technology used to drive business network services. The advent of Carrier Ethernet saw both technologies run in tandem for a time, but increasingly the latter is becoming the ‘go to choice’ worldwide. Statistics from Vertical Systems1
now show
Ethernet bandwidth exceeds total TDM based services in enterprises worldwide. Carrier Ethernet’s popularity will only increase as enterprises continue to move towards a network-as-a-service model and the adoption of network solutions with flexible, scalable and high powered bandwidth in line with their business needs. The increasing popularity of Carrier Ethernet will not only benefit multiple verticals, in birthing and enhancing new technologies, but also demonstrates the trust senior IT executives now have in the solution.
2. The use of packet networks for timing distribution Traditionally, operators have relied on networks to synchronise critical applications that depend on accurate time and frequency information. Traditional TDM based networks provided the distinct advantage that all connection and redistribution points, as well as communication
