Under HTTP 1.0, connections should always be closed by the server after sending the response. [1]Since at least late 1995, [2] developers of popular products (browsers, web servers, etc.) using HTTP/1.0, started to add an unofficial extension (to the protocol) named "keep-alive" in order to allow the reuse of a connection for multiple requests/responses.
The Keep Alive signal can be used to trick intermediate hosts to not close the connection due to inactivity. It is also possible that one host is no longer listening (e.g. application or system crash). In this case, the connection is closed, but no FIN was ever sent. In this case, a KeepAlive packet can be used to interrogate a connection to ...
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. [1] It can provide loop detection, authentication , transmission encryption , [ 2 ] and data compression .
Point-to-point encryption (P2PE) is a standard established by the PCI Security Standards Council.The objective of P2PE is to provide a payment security solution that instantaneously converts confidential payment card (credit and debit card) data and information into indecipherable code at the time the card is swiped, in order to prevent hacking and fraud.
If the data in a single write spans 2n packets, where there are 2n-1 full-sized TCP segments followed by a partial TCP segment, the original Nagle algorithm would withhold the last packet, waiting for either more data to send (to fill the packet), or the ACK for the previous packet (indicating that all the previous packets have left the network).
A 1 Gbit/s point-to-point millimeter-wave link installed in the UAE A point-to-point wireless unit with a built-in antenna at Huntington Beach, California. With the exception of passive optical networks, modern Ethernet is exclusively point-to-point on the physical layer – any cable only connects two devices.
The term half-open connection can also be used to describe an embryonic connection, i.e. a TCP connection that is in the process of being established. TCP has a three state system for opening a connection. First, the originating endpoint (A) sends a SYN packet to the destination (B). A is now in an embryonic state (specifically, SYN_SENT), and ...
