26 de nov. de 2009 · Crucially, the TIME_WAIT connections (whether they are on the server side or on the client side) each occupy one of these tuples. With the TIME_WAIT s on the client side, it's easy to see why you can't make any more connections - you have no more local ports.
21 de may. de 2015 · A tcp session is identified by the tupple (sourceIP, sourcePort, destIP, destPort). Hence the TIME_WAIT does work on every tcp connection. Regarding the closing side, in some scenarios, closing from the client side can reduce TIME_WAIT sockets on the server, thus slightly reducing memory.
5 de dic. de 2020 · TIME-WAIT - represents waiting for enough time to pass to be sure the remote TCP received the acknowledgment of its connection termination request. [RFC 792, p.22] The purpose is to wait long enough for any outstanding traffic to be processed before potential reuse of the port.
Pax is correct about the reasons for TIME_WAIT, and why you should be careful about lowering the default setting. A better solution is to vary the port numbers used for the originating end of your sockets. Once you do this, you won't really care about time wait for individual sockets.
CLOSE_WAIT indicates that the remote endpoint (other side of the connection) has closed the connection. TIME_WAIT indicates that local endpoint (this side) has closed the connection. The connection is being kept around so that any delayed packets can be matched to the connection and handled appropriately.
Así, para el lado del servidor TIME_WAIT las conexiones en exactamente el mismo par de puertos podrían restablecerse inmediatamente y con éxito, y para el lado del cliente TIME-WAIT en la segunda iteración connect() justamente fracasado. En resumen, la cuestión tiene dos vertientes:
18 de mar. de 2024 · In this tutorial, we’ll study the cost of many TIME_WAITs on the server side. First, we’ll understand the function of the TIME_WAIT by examining its role in a TCP connection. Then, we’ll explore the effects of too many TIME_WAITs on a server and the associated cost.
