SDN/NFV: Enhancing Network Capacity and Functionality

Posted on November 10th, 2015 by Editor (Emma)

SDN and NFV have been developed to help meet the challenge of increasing demand for services and user expectation of rapid provisioning and universal availability. Both rely on virtualization, the ability to make a piece of equipment look like another via the magic of software. SDN was originally developed to address the problems of large data centers, where virtualization of hardware and operating system is important. It will likely spread to other areas, including the WAN, where virtualization and the ability to dial up bandwidth and related characteristics would be extremely valuable as well. NFV is an outgrowth of SDN in many respects, concentrating on backbone networks, where the need to rapidly reconfigure resources is key.

As the name suggests, optical networks form a class of networks where optical, rather than electronic, components are the building blocks of the network. Compared to metallic cable, fiber optic systems offer greater bandwidths, lower attenuation, and no crosstalk or electrical interference.

Tutorial – SS7 or C7: Signaling System #7

Posted on October 23rd, 2014 by New Admin

Signaling System #7 (SS7), also known as C7 in Europe, is a critical component of modern telecommunications systems. Despite the upcoming migration to IP networks and evolution to IP-centric architectures such as the IP Multimedia Subsystem (IMS), it remains the glue that binds all telecommunication networks together.
