The third step, because there is no such problem on the first level switch and S5500 , all can be located in the first and two levels between the network cable, because the cable distance is longer, about 100m , and the field can not be replaced. Therefore consider can reduce the negotiation speed of the port to reduce the requirements of the network cable, try to force the port to 10M full-duplex settings, set after the ping packet is n

What is QoS?
QoS (Quality of Service), a security mechanism of the network, is a technique used to solve problems such as network latency and congestion. It is necessary for key applications and multimedia applications. When the network overload or congestion, QoS ensures that important traffic is not delayed or discarded, while ensuring the efficient operation of the network. In short, it is to improve the network priority of the game program so as

guardian to each aggregate object. All operations on this resource are handed over to this guardian, and a lock-free queue is used to quickly queue up and hand over to the guardian. Through reactive programming, we can also avoid the occupation of CPU threads for a resource operation for too long. As long as we finish the competition for resources, we can immediately dispatch another thread to do the rest. In this way, serial sequential operations and parallel operations can be perfectly combi
