How Nefsis Delivers Superior Multipoint
Video Conferencing Quality

Web and multiparty video conferencing is uniquely dependent on high-performance and low round-trip latency among all the components in your conference.  Nefsis addresses every component involved to ensure the best interactivity among all participants. In particular, the distributed Nefsis cloud and end-to-end parallel processing technologies are years ahead of the competition.
 

How it Works: Cloud Computing Meets Multi-Core, Parallel Processing Technology

Nefsis provides a true, massively distributed cloud for unrivaled quality in multipoint video conferencing.  The Nefsis cloud constantly adapts to changing conditions on the Internet, as well as your local network, delivering the highest quality experience possible for your multipoint video conference.

Some products claiming to be a 'cloud' are really just a large centralized data center supplying a service, without any of the benefits of cloud-based service distribution.  A true cloud, like Nefsis, offloads and distributes the experience across the Web.  Nefsis does this by using a massive network of distributed computers to ensure the highest quality video conferencing experience; minimizing latency while delivering all the benefits of load-balancing, failover, and the scalability that true cloud architecture provides.

Because low latency is so critical in video and VoIP conferencing, the goal at Nefsis is to provide sub-30ms response time for every conference participant by expanding our distributed network to the far reaches of the globe.

Security is our highest priority.  All connections are made through your firewall, over an SSL3/TLS secure connection to an access point.  Your entry point to the Nefsis cloud changes constantly, adapting to network conditions, in order to provide the fastest connection possible.

Once connected to an access point, Nefsis leverages the built-in load balancing and failover abilities of its distributed cloud to maximize uptime and significantly improve overall video conferencing performance.

Other benefits of the Nefsis cloud include redundancy, scalability, failover and load balancing.

Unlimited scalability is ensured.  New access points in the Nefsis distributed system can be added quickly to provide additional capacity, or coverage to new geographic regions.

The Nefsis cloud is substantially different than any other multipoint video conference product available today.  Because most other conference providers use a centralized data center (or on-premise MCU or MUX), they cannot adjust to changing Internet conditions or geographic availability to provide the best conference experience possible. 

These centralized data centers, by definition, are not physically close to a broad base of users, thereby increasing overall latency and causing major reductions in the quality of video (lower frames, lower resolution) and an increase in VoIP delay and jitter.  The Nefsis massively distributed cloud solves all these issues, utilizing the industry's first true cloud-based delivery platform for multipoint video conferencing applications.

 

Parallel Processing

Is your conferencing solution only leveraging one core of your multi-core processor?

If your conferencing application was built using traditional programming practices, then you're probably not leveraging the full capabilities of your computer. Today's computers have multiple processor cores but most conferencing applications were designed to use only a single core.  Nefsis is the first multipoint video conferencing application to fully leverage all the cores of your computer, no matter how many.  Nefsis was designed from the bottom up as a completely parallel processing application.  In Nefsis, each of its discrete functional areas is an independent piece of logic, working together to form a fluid experience as they are distributed evenly across all available cores in your computer.

With multi-core desktop and conference room PCs, HD, roundtable and multipoint video are easy. Each of the various Nefsis capabilities, including video, audio (VoIP), and sharing are distributed across all the cores of each conference participant.  As new and more powerful computers arrive on the scene, you don't have to upgrade your software to expand the capabilities of Nefsis.  Nefsis will automatically provide higher resolutions, including high definition (HD), and at higher frame rates with more conference participants as your computing power grows.  This is how Nefsis rivals the most expensive telepresence systems available today, but accomplishes it in a software application that can easily be upgraded and improved without the cost of replacing expensive equipment.

In order to fully scale their capabilities across multiple cores, every other major video conferencing solution in the market will need to redesign their applications to take into account multi-core, parallel programming.  Nefsis is already years ahead in this process.

MMX Processor Extensions

In addition to multi-core technology, Nefsis fully leverages all of the MMX capabilities of your CPU, including SSE2 to SSE4. This significantly improves the multimedia experience, by reducing overall processor requirements for encoding and decoding of video, audio, and sharing.

The processing power of the Intel Pentium® and future multi-core computers
is awesome in comparison to past computers - even outstripping the performance of dedicated video coder/decoders and multiplexers. In many corporate environments, the technology refresh cycle for desktops is faster than installed, hardware-based boardroom video conferencing systems. In short; with the Nefsis parallel processing software-as-a-service, your desktop has greater performance capabilities than many boardroom video conferencing systems, and will keep pace with technological advances in the normal course of updating desktop computers in your organization.
