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.
In software engineering, a connection pool is a cache of reusable database connections managed by the client or middleware. It reduces the overhead of opening and closing connections, improving performance and scalability in database applications.
Subscribed topic changes: Users may want to get updates regarding the weather in their location, or monitor a web page to track changes, for instance. Real-time push notifications may raise privacy issues since they can be used to bind virtual identities of social network pseudonyms to the real identities of the smartphone owners. [26]
In computing, Dynamic Data Exchange (DDE) is a technology for interprocess communication used in early versions of Microsoft Windows and OS/2. DDE allows programs to manipulate objects provided by other programs, and respond to user actions affecting those objects.
UDP hole punching is a technology that leverages this trait to allow for dynamically setting up data tunnels over the internet. [6] ICMP messages are distinct from TCP and UDP and communicate control information of the network itself. A well-known example of this is the ping utility. [7] ICMP responses will be allowed back through the firewall.
When a network is first connected to, Windows Vista prompts to choose the correct network type. On subsequent connections to the network, the service is used to gain information on which network is connected to and automatically switch to the network configuration for the connected network. Windows Vista introduces a concept of network profiles.
XDP (eXpress Data Path) is an eBPF-based high-performance network data path used to send and receive network packets at high rates by bypassing most of the operating system networking stack. It is merged in the Linux kernel since version 4.8. [2] This implementation is licensed under GPL. Large technology firms including Amazon, Google and ...
Windows Server 2003, and legacy NAS devices use SMB1 natively. SMB1 is an extremely chatty protocol, which is not such an issue on a local area network (LAN) with low latency. It becomes very slow on wide area networks (WAN) as the back and forth handshake of the protocol magnifies the inherent high latency of such a network. Later versions of ...
