Error-checking mechanisms.TCP provides extensive error-detection procedures, such as determining the connection timeout period, providing a checksum field, and receiving and sending acknowledgments. On the other hand, UDP only performs basic problem-checking using checksums. ...
Acknowledgment.TCP sends packets to and accepts packets from the network layer. After receiving the packets, the receiving device sends an acknowledgment (ACK) back to the sender to confirm receipt. If the sender doesn't receive an ACK within a specified timeout period, it retransmits the data...
ipc.client.ping If this parameter istrue, the HDFS client will wait for the response from the server and periodically send the ping message to avoid disconnection caused by tcp timeout. If this parameter isfalse, the HDFS client will set the value ofipc.ping.intervalas the timeout time. I...
header. When receiving a malformed packet whose size is claimed to exceed the maximum size of an ICMP message, that is, 64 KB, a device will allocate a payload of more than 64 KB, leading to a memory allocation error. As a result, the TCP/IP protocolstackcrashes and the device breaks...
This idle timeout setting basically keeps a TCP or HTTP connection open without relying on clients to send keep-alive messages. If a period of inactivity is longer than the timeout value, there's no guarantee that the TCP or HTTP session is maintained between the client and your cloud ...
The reliability of the TCP protocol lies not only in the three-way handshake, but also in the timeout and retransmission mechanism. In normal cases, if the client does not receive the SYN-ACK response from the server within a certain period of time after sending a SYN packet, the client ...
If the ELB node receives the SYN-ACK packet from the backend server within the timeout duration, it sends an ACK packet to the backend server and declares that the backend server is healthy. Then, the ELB node sends an RST packet to the backend server to terminate the TCP connection. ...
UDP is a connectionless transport-layer protocol. Therefore, RADIUS uses the packet retransmission timeout mechanism to ensure that packets can be sent to the remote end. HWTACACS uses TCP, a connection-oriented transport-layer protocol, which provides more reliable network transmission. Packet ...
An availability group listener is associated with a unique DNS name that serves as a virtual network name (VNN), one or more virtual IP addresses (VIPs), and a TCP port number. For more information, seeConnect to an Always On availability group listener. ...
其实说HTTP协议可靠协议并不是特别的准确,HTTP的可靠性一部分来自于HTTP协议自身,一部分来自于它所依赖的上层TCP协议。 TCP本身就是一个可靠的传输协议,它的可靠性其实就是来自于三次握手,通过客户端与服务器的沟通来确定是否建立连接,UDP就没这么麻烦,传过去就完事了,我管你收没收到。所以基于这样的因素,TCP就不...
