As Unified Communications (UC) technology continues to develop, individuals and businesses are presented with more ways to network and share data. In order to maintain optimal productivity, successful companies must find ways of using these innovations as easily and efficiently as possible. Your company's UC strategy strives to achieve just that, and one of the most valuable tools available today to help coordinate communications devices and programs is Session Initiation Protocol (SIP).SIP seamlessly integrates standard voice, video, instant messaging, and other types of real-time and message-based communication, as well as incorporating presence information about user location and availability. All of this data is transmitted over your existing IP network, making SIP easy to integrate into your UC strategy.
Since SIP passes all forms of peer-to-peer communication data through carrier systems as IP traffic, it does not require a traditional PSTN gateway. SIP trunking allows your business to manage all of its communications and data traffic over your IP network, eliminating the need to maintain a separate trunking system for telephony. SIP simultaneously maintains network efficiency and potentially improves call speed. To achieve this, call packets travel as data until they reach the other user's device, and like traditional telephone service, all the packets travel along the same path. This travel pattern assures that they reach the receiving device in the correct order, thus producing desirable call speed and quality.
If you’re looking to streamline and boost your UC strategy, SIP can help you do so, with an end result of greater efficiency and cost-efficiency. In addition to rendering PSTN gateways redundant, using SIP trunking to process your telephony and internet needs over your IP network means that SIP allows you to maximize your bandwidth utilization efficiency. Both telephone usage and internet usage are characterized by erratic spikes and dips throughout the day, and two systems optimized for each at peak usage will see a lot of waste during the lulls.
SIP has distinct advantages over similar protocols, such as H.323. SIP is more widely compatible with other protocols, can incorporate a more varied range of peer-to-peer communication formats, and is often easier to understand and access for novice end users.
Combining both systems with SIP trunking allows you to optimize for the average usage of both. Further, the use of Least-Cost Routing allows your company to choose the path of outbound communication by price, enabling you to route international calls through the cheapest service providers and save money.

research has uncovered in many large enterprise data center networks today. Jon outlines all of the factors including cloud and virtualization that are changing the data center, but the network has been slow (like the dinosaur) in adapting to all of the changes. As a result, he says “the data center networking dinosaur is adapting but we are rapidly approaching a breaking point.” Jon graciously gave us permission to use the following chart, which outlines ESG’s recent findings on problems with data center networks today. Do you see your issues reflected here?
That said, we are adding to the leadership position NEC has staked out with this new core OpenFlow switch. This energy-efficient hardware provides high throughput, with low latency, delivering 1.28 Terabits of switching performance with a compact footprint. The PF5820 is designed for building high performance, secure, and programmable networks. 
And helping to make sure it all runs smoothly? NEC’s UNIVERGE 
NEC continues to be a leader in the OpenFlow innovation movement. This week in Tokyo our colleagues in Japan at NEC Corporation are demonstrating another first: OpenFlow for Android, at
