Keepalive time is the duration between two keepalive transmissions in idle condition. TCP keepalive period is required to be configurable and by default is set to no less than 2 hours. Keepalive interval is the duration between two successive keepalive retransmissions, if acknowledgement to the previous keepalive transmission is not received.
Keepalive makes it difficult for the client to determine where one response ends and the next response begins, particularly during pipelined HTTP operation. [11] This is a serious problem when Content-Length cannot be used due to streaming. [12] To solve this problem, HTTP 1.1 introduced a chunked transfer coding that defines a last-chunk bit. [13]
A keepalive is a message sent by one device to another to check that the link between the two is operating, or to prevent the link from being broken. Keepalive or keep-alive may also refer to: HTTP keep-alive, using a single TCP connection to send and receive multiple HTTP requests/responses; Keep-alive electrode, of a krytron
Keepalive is a permanent outdoor sculpture in Niedersachsen, Germany, commissioned by the Center for Digital Cultures, Leuphana University Lüneburg. The title, Keepalive, refers to the keepalive signal, a message – often sent at predetermined intervals – that is used on networks to check the link between two devices, to make a diagnosis or ...
Maximum segment lifetime or MSL is the time a TCP segment can exist in the internetwork system. It was defined in 1981 to be 2 minutes. [1]For this specification the MSL is taken to be 2 minutes.
Applications can be written to send keepalive messages [3] periodically to prevent a firewall from dropping the connection during periods of no activity or for applications which by design have long periods of silence. The method of maintaining a session's state depends on the transport protocol being used.
In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a computer system. [1] [2] Heartbeat mechanism is one of the common techniques in mission critical systems for providing high availability and fault tolerance of network services by detecting the network or systems failures of nodes or daemons ...
Nagle's algorithm is a means of improving the efficiency of TCP/IP networks by reducing the number of packets that need to be sent over the network. It was defined by John Nagle while working for Ford Aerospace.
