event will be audited as an exception event, as it seems normal, since it is necessary to maintain a persistent connection, it should not be disconnected. Now it is disconnected, and that is not necessary. Second, for those environments where bandwidth is scarce resources, heartbeat packets occupy considerable resources, such as 3G users, without actual data transmission, the heartbeat packets sent will be completely wasted. Why does VPN need to maintain a persistent connection? Isn't it easy t

client to confirm each other before the application protocol transmits the First Data byte and negotiate an encryption algorithm and password key. During data transmission, the record protocol uses the key generated by the handshake protocol to encrypt and decrypt the data to be exchanged. SSL is independent from the application, so any application can enjoy its security without worrying about the execution details. SSL is placed between the transport layer and the application layer of the netw

verification, and information integrity. The SSL protocol consists of many sub-protocols, two of which are handshake protocol and record protocol. The handshake protocol allows the server and client to confirm each other before the application protocol transmits the First Data byte and negotiate an encryption algorithm and password key. During data transmission, the record protocol uses the key generated by the handshake protocol to encrypt and decrypt the data to be exchanged. SSL is independe
