Video Conference System. To this end,
IT Departments have to consider, in times of network congestion Video
Meeting Quality can be guaranteed, companies should build special networks for video conferencing, and how no loss of performance and reliability of premise, deal also includes video conferencing and data traffic transmission.
Order to ensure that applications do video conferencing are completely prepared, companies should first of all WAN application traffic on a comprehensive understanding of the whole. Will cause the network administrator can not clearly determine whether the corporate network for video conferencing traffic, and when the WAN bandwidth is insufficient, it should be upgraded network bandwidth to avoid performance problems. If the network administrator needs to clearly understand the application of the number of occupied bandwidth, wide area network optimization of video conferencing across the need to consume much bandwidth, traffic, and the application layer in the flow of what percentage of each. They are important applications can be separated flow, control and containment applications in which non-essential traffic, or video conferencing has improved the quality of service based on the appropriate increase in bandwidth to meet business needs.
In the use of traditional routers, the edge in the management of the network, MPLS (Multi Protocol Label Switching) in the
Monitor The application of local network traffic and take appropriate traffic control has some limitations, and may lead to a critical network edge video conferencing and data transmission congestion point. But this does not do anything, good application delivery
Technology MPLS should be able to address their own equipment or with the combination of edge routers, used in video conferencing and data application traffic by adding the appropriate way to mark in advance for those who traffic in the network edge to optimize. This is precisely to exclude limitations of MPLS network management personnel concerns, the technology to maximize the video conferencing and data traffic congestion occurring to minimize the number of times to achieve service level agreements (ServiceLevelAgreement, SLA) targets. Meanwhile, the application delivery network
Solutions It should also be able to help intelligent compression technology, according to traffic type is compressed data applications to help enterprises reduce bandwidth consumption and to ensure that those who need high-quality video traffic to ensure voice will not be compressed.
As video conferencing quality improvement and cost reduction of the highlights, video conferencing highly distributed enterprises of all ages. However, between the LAN and WAN junction, became leading to network congestion and affect the quality of the main location of the meeting. When we defined the bandwidth requirements and access to all applications for visibility and had to consider further delay, delay jitter and packet loss may seriously affect the meeting of these three quality problems.
For video conferencing, especially for two-way session, the delay will lead to a decline in user experience. But only for the video conference data packets into the network while waiting to get a higher priority than other traffic is obviously not enough, because it is like a crowded highway, ranked first not represent the position can be quickly reach their destination. Really should do is more rigorous and intelligent video conferencing all the relevant agreement with the classification to ensure that each traffic type can allocate appropriate bandwidth.
Compared to lag and delay in speech communication conflict, delay jitter, video conferencing from each packet in the transmission process encountered in various unpredictable delay caused. Usually lined with jitter buffer, or to temporarily save and then "smoothed out" audio and video data packets, the required jitter of not more than 100ms, will cause the problem worse. If the basis of the traditional method of adding more intelligence and policy-based bandwidth control policy for data traffic and voice and video traffic are allocated and to maintain a certain speed and quality, so this question can be solved.
Video conferencing also often faced with packet loss, when the packet loss rate reaches or exceeds 3%, meeting the audience clearly felt that the meeting will be off side, or even dropped. The best way to solve this problem is the intelligent control of IP networks, wide area network will be available in the IP joint road congestion and minimize unpredictability, will maximize the performance of applications, thus achieving unparalleled flow control and performance optimization.
In addition, the video conferencing will always affect network and application performance, because of the different protocols used in network operations, the different, more interactive applications that random data types and more difficult to predict in advance the bandwidth required. More and more enterprises begin hopes intelligent solutions, application delivery technology with the visibility, control and acceleration is no doubt that intelligence provided strong support.
In summary, excellent application delivery solutions for video conferencing applications, a good solution to network congestion and the resulting delay, jitter and packet loss problems, take to avoid at the junction of LAN and WAN the quality of the video conference loss.
