Software-Defined Networking Will Transform Middle East Enterprise and Service Provider Networks into a Platform for Innovation, says Expert
Software Defined Networking (SDN), a concept that is gaining adoption worldwide has the potential to revolutionize the networking industry in the Middle East

DUBAI, United Arab Emirates, 6 July 2012: Over the last 6 months, Software-Defined Networking or SDN has become the hottest buzzword across the globe and here in the Middle East. Not just in enterprise networking but service providers as well, with research networks, large DC hosting and cloud providers as some of the earlier adopters. An emerging concept that promises improved network performance, flexibility and manageability, SDN has the potential to revolutionize networking unlocking a wave of innovation for application services. In fact, IDC forecasts that SDN will grow from a $200 million market in 2013 to $2 billion in 2016.
Sufian Dweik, Regional Manager, MENA at networking solutions company Brocade Communications says that to better understand the benefits of SDN it is important to look at how it fits in the broader perspective of IT trends and ask what problems it will it solve and who will it help.
Today’s networks are inefficient, difficult to scale, cost-intensive in time and resources, and incapable of supporting flexible operations. In most cases, all networking intelligence is distributed across physical switches and routers using standardized protocols. Configuration of networking equipment is primarily performed on each switch independently. The result is an excessively complex network architecture. To enforce a change, network operators will have to go down to the individual switch or router and re-configure the routing protocol; a time consuming task especially in large networks and data centers. To use an analogy, it is akin to writing a book using a chisel on stone slabs. If you make a mistake, you must pick up your chisel and re-write the content on another slab, making it a very tedious task.
SDN effectively separates network data traffic processing from the logic and rules controlling the flow of that data. It gives service providers and enterprises control over how to manage their data, to the level that they are able to enforce different rules and routing capabilities, including deciding what type of data goes local and what type of data goes remote. In essence, SDN can enable an organization to gain visibility and control access to the network and resources to the granular level, enabling IT managers to solve specific issues that affect the network. To extend the earlier metaphor, imagine you are writing the same story as before, but this time you are using a computer. If you make an error, it is automatically highlighted, or corrected. You can re-arrange the story with a click of a button and everything is stored and viewable in one avenue rather than on multiple stone slabs. Suddenly, your work has become faster, more flexible and easier to manage through a single portal.
By enabling enterprises to have a central overview of the entire network architecture, customers are able to tune the network accordingly to meet business needs. More importantly, it gives network operators and vendors an avenue to experiment with network optimization ideas and strategies in a real network setting without affecting the current flow of data. Operators can now customize their networks to better suit their business needs. This holds the promise of starting a new network innovation cycle, with companies fighting to create network-based applications and services.
The dramatic growth in the SDN market will be driven by companies working towards solving existing problems with networks – security, robustness and manageability and by innovating new revenue generating services on network infrastructures. Ultimately, the goal is to provide a highly flexible cloud-optimized network solution that is scalable within the cloud. In our view, this “new” network will be powered by fabric-based architectures, which provide the any-to-any connectivity critical to realizing the full benefits of SDN. These include network virtualization, programmatic control of the infrastructure, automation and dynamic configuration, on-demand service insertion and pay-per-use, all through standards-based software orchestration tools. Cloud service deployment will be faster, data centre management will be simpler and network operation will be easier.
While it is still early days, SDN has the potential to transform network infrastructures into a platform for innovation. We are partnering with industry technology leaders and network operators and also working very closely with standards bodies like the Open Networking Foundation (ONF) to make this a reality. The success of SDN lies in enabling innovation through an open environment in order to deliver high value, game changing applications for our customers.
