The VidyoRouter is the core infrastructure product for conducting all videoconferences. It is an intelligent routing appliance that uses patented scalable video packet switching technology to achieve unprecedented performance and features without the need for expensive, time consuming transcoding. All video traffic is managed by the VidyoRouter. Additionally, conferences can span across multiple VidyoRouters, achieving maximized WAN utilization as well as redundancy and efficiency.
The VidyoRouter’s technology provides each individual conference participant with the following critical features:
Rate and resolution matching – This allows conference participants to join from any network location and environment. It eliminates the lowest common denominator aspect of videoconferencing and allows every participant to send and receive the best possible video based on network condition, available CPU and screen resolution. Users on low capacity desktops and mobile devices can receive video from HD participants without the need for transcoding, and users at low bandwidth locations can receive video from participants sending at high bit rates. These calculations are all done by the VidyoRouter on the fly, as it dynamically adjusts to changing network conditions.
Error resilience – The VidyoRouter is at the heart of Vidyo’s ability to overcome network issues such as latency, packet loss, and jitter. The VidyoRouter was built to provide resilient video over any kind of network and eliminates the need for expensive dedicated networks and QoS. By utilizing Scalable Video Coding in conjunction with the VidyoRouter’s patented video packet switching technology, the video can withstand upwards of 20% packet loss without experiencing the typical picture breaking that other videoconference solutions experience at less than 1% packet loss.
Low latency – A critical aspect of videoconferencing is the natural interaction between participants. In order to achieve this level of interaction, a solution must maintain low end to end latency. Typical videoconference solutions have higher latency because they must transcode as well as implement other technologies that introduce more latency. The result is an unreliable experience that is unnatural and uncomfortable for interactive communications. The VidyoRouter is optimized for real time interactive communication and typically adds less than 20ms to any multipoint videoconference in real world global deployments. This is especially critical for a globally distributed enterprise where geographic distances heavily impact the total round trip time of video.
Cascading and redundancy – The VidyoRouter further extends the capabilities of the VidyoConferencing infrastructure by providing built in router to router cascading and redundancy features. VidyoRouter cascading creates a cloud network of VidyoRouters that communicate with each other and allow conferences to span across them in an intelligent manner. This minimizes the amount of WAN bandwidth required for location to location conferences, and maximizes use of inexpensive and abundant LAN bandwidth. Also built in to the VidyoRouter architecture is native fall back where upon if a router fails, the system will utilize the next available VidyoRouter in the pool.
Secure network traversal – The VidyoRouter supports secure conferences using AES 128bit encryption. This provides industry standard protection for all conference content. Additionally, with VidyoRouter cascading, routers can be placed on the inside and outside of a trusted network location. This allows IT administrators to create specific rules for router to router communication firewalls. Doing so protects the inside trusted network from ever being directly accessed from any outside element. This also eliminates costly session border controlling devices that create artificial bottlenecks on the network and impede performance while raising costs dramatically.
