We take direct connections to 4 of the worlds largest Tier-1 Internet Providers offering diverse global routes to provide low latency connections anywhere in the world ensuring you stay online even if one of them may experience an outage. Since light travels down light in approximately a straight line we can use the formula (D = T * V) where D is the distance the fiber travels, T is the time it takes to travel, and V is the velocity of light. A multi-cloud strategy can lower overall latency if it is able to take advantage of monitoring that shows which cloud is performing best from each network and geography that the users are. AV Network is supported by its audience. Lag - A term used to describe a delay between input and execution. It comes into even sharper focus when players at different distances from a particular game server play each other. Edge Computing is the Answer. For the user in Germany, the minimum observed latency is 201 ms using HTTP (S) load balancing versus 525 ms using HTTP (S) through the network load balancer. It typically refers to delays in transmitting or processing data , which can be caused by a wide variety of reasons. Latency is the elapsed time between the network driver processing an incoming packet and the network driver sending the packet back. In the past year we have heard announcements from most stock exchanges about upgraded trading platforms, brokers. This paper discusses some unexpected challenges. An inside and hands-on look to a distance musical interactive performance and education A/V streaming system. Our low-latency network infrastructure platform spans North America, Europe and Asia, and provides both domestic and international point-to-point low-latency connectivity, helping you to easily extend reach.
