consideration for multiple networks and collaborative maintenance optimization, only through a single network to improve the performance of multiple networks passively. Multi-network collaboration ideas and Research In view of the coordinated development of multiple networks, ZTE has studied multiple network connections, user perception, service delivery, and co

CLOSED: No connection is active or in progressEstablised: The state of the connection has been established;Syn_sent: Send the active line (SYN sign) of the connection packet;SYN_RECV: Received a request to connect the active connection packet;FIN_WAIT1: The socket Service (socket) has been interrupted and the connection is disconnected;Fin_wait2: The connection has been hung up, but is waiting for the other host to respond to the packet disconnection confirmation;Time_wait: The connection has be

First, through the timing of email to detect network connectivity Copy Code code as follows: #/bin/bash echo "Daily Test mail" > State.txt Mail-s Server_state Abc@jb51.net Rm-df./state.txt ~ Crontab-e Add the following tasks * * */root/checknkmail Time-Sharing and Lunar Week Second, timed detection network status by e-mail Checkserve

time_wait is closed. If the 2msl of time_wait is not directly closed, if the last Ack is lost, the server will not resend the ACK. If the server cannot receive the ACK, it will resend the final fin. when the client is already closed, it will respond to an rst, this rst will be interpreted as an error by the server. Allowed repeated segments disappear in the Network: each time a TCP connection is established successfully, the old repeated groups from

team that truly understands the needs and technologies of cloud computing is often better than a large number of participants who are consciously or unconsciously standing in various positions.From the current situation speculation, in a long period of time, the network project will continue along the current path, on the one hand in the distributed model of the implementation of new network functions, as

At present, LTE access bearer network is not widely used, but there are still many problems. So I have studied the development status and problems of the LTE access bearer network. I will share with you here, hoping it will be useful to you. From 2G/3G to LTE access bearer network, more than 90% of wireless site addres

NetWorkReceive in android and get the current network connection status Now, it is absolutely difficult for an APP to survive without the network, and there will be many frequent network operations, request data, and transmit data. Therefore, we need to have a better understanding of the

In C #, you can use multiple methods to determine the network connection status. For example, you can use Win32 APIs to determine the connection status, or you can directly ping a website to determine the connection status. The following describes a method class that I write most to determine the

The ADSL Broadband Access Network is still quite common, So I studied how to check the connection status of the ADSL Broadband Access Network. Here I will share it with you, hoping it will be useful to you. Now, there are more and more friends who use ADSL, LAN, and other broadband methods for high-speed Internet access, such as the LAN-based ADSL Broadband Acces

During Android network application development, it is often necessary to determine whether the network connection is available. Therefore, it is often necessary to listen to changes in the network status. For android network status
