At present, many devices are often converted through routers and firewalls. However, the price of the devices that want to meet the OC192 line rate is usually very high, and the investment in comprehensive monitoring of the entire network is very huge. Therefore, using special algorithms and devices to analyze network data while reducing device prices is a feasible solution for the whole network monitoring of VoIP. This paper proposes a new algorithm

We know that IOS can get a maximum execution time of 600 seconds after enabling background tasks. How do some apps that need to be downloaded in the background or kept connected to the server exceed the limit of 600 seconds? For example, Netease open classes can be used for continuous download in the background, and Youku can also continue caching in the background. How does this happen? Generally, to enable Ios to run in the background for a long time, you need to declare
