AUSTIN, TX -- (Marketwire) -- 11/28/12 -- Software Defined Networks (SDNs) represent a transition away from legacy distributed protocols and fixed networks to a network where resources are centrally controlled and transport is allocated across a number of viable alternative networks. The SDN replaces traditional networks that have many disparate types of network elements and protocols that are very challenging to manage.

Software Defined Networks enable mobile operators to architect a new virtual-like network infrastructure that has Carrier Ethernet as the foundation to provide the best in mobile backhaul (MBH). Carrier Ethernet is at the core of the transition from multiple legacy networks to software defined networks (SDN). Cost efficient mobile backhaul for new emerging 4G networks may be significantly impaired without SDNs.

iGR's new market research report, "Software Defined Networks: Impact on Mobile Backhaul," provides an introduction to software defined networks in mobile networks and their potential impact on mobile backhaul.

"iGR views SDNs as the start of a process of virtualization of the mobile network, from fronthaul and backhaul through to the EPC itself," said Iain Gillott, president and founder of iGR, a market research consultancy focused on the wireless and mobile industry. "As the industry has moved toward the use of 'off the shelf' hardware for the packet core, so the next logical step is toward full virtualization. SDNs are the first step down this long road."

The following key questions are addressed in iGR's new research study:

• What are Software Defined Networks?
  
  
• How did SDNs originate?
  
  
• Why are mobile operators interested in SDNs?
  
  
• What are the benefits of SDNs?
  
  
• What are some of the challenges surrounding the implementation of SDNs?
  
  
• Who are the major SDN players?
  
  
• What is the prognosis for SDNs' adoption?
  
  

The information in this report will be valuable for:

• Mobile operators
  
  
• Mobile infrastructure OEMs
  
  
• SDN solution vendors
  
  
• Mobile backhaul solution providers
  
  
• Financial analysts and investors
