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...
Open ports— What TCP/IP port does your database listen on? The firewalls at some companies might block connections to the default port for your database engine. The default for Timestream for InfluxDB is 8086. AWS Region— What AWS Region do you want your database in? Having your databa...
Another problem is that when a client sends a request to the server at the same time that the server closes the TCP connection, it can result in what is known as arace condition. To avoid this issue, the server should send a "408 Request Timeout" status code to the client before clos...
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...

If necessary, modify Transmission Control Protocol (TCP) idle timeout (optional). Reviewtimersbefore you change the default. Security NAT Gateway is built on the zero trust network security model and is secure by default. With NAT gateway, private instances within a subnet don't need public IP...
TCP provides reliable delivery due to the process of error detection, in which TCP retransmits and reorders packets after they arrive. However, it can introducelatencyin a TCP stream. UDP on the other hand doesn't retransmit data. Highly time-sensitive applications, such as voice over IP, st...
Session-timeout periodThe session-timeout period is an availability-replica property that determines how long connection with another availability replica can remain inactive before the connection is closed. The primary and secondary replicas ping each other to signal that they're sti...
timeout period, the client resends a request packet. Specifically, the RADIUS client retransmits the request to the same server a specified number of retransmission times. If no reply is received, the client sends the request to a different server, regardless of whether the master/backup or ...
