Simple Service Discovery Protocol
The Simple Service Discovery Protocol (SSDP) is a network protocol based on the Internet protocol suite for advertisement and discovery of network services and presence information. It accomplishes this without assistance of server-based configuration mechanisms, such as Dynamic Host Configuration Protocol (DHCP) or Domain Name System (DNS), and without special static configuration of a network host. SSDP is the basis of the discovery protocol of Universal Plug and Play (UPnP) and is intended for use in residential or small office environments. It was formally described in an IETF Internet Draft by Microsoft and Hewlett-Packard in 1999. Although the IETF proposal has since expired (April, 2000), SSDP was incorporated into the UPnP protocol stack, and a description of the final implementation is included in UPnP standards documents. Protocol transport and addressing SSDP is a text-based protocol based on HTTPU, which uses User Datagram Protocol, UDP as the underlying transport pro ...

Link-local Address
In computer networking, a link-local address is a network address that is valid only for communications on a ''local link'', i.e. within a subnetwork that a host is connected to. Link-local addresses are typically assigned automatically through a process known as link-local address autoconfiguration, also known as auto-IP, automatic private IP addressing (APIPA, specific to IPv4), and stateless address autoconfiguration (SLAAC, specific to IPv6). While most link-local addresses are unicast, this is not necessarily the case; e.g. IPv6 addresses beginning with (), and IPv4 addresses beginning with () are multicast addresses that are link-local. Link-local addresses are not guaranteed to be unique beyond their network segment. Therefore, routers do not forward packets with link-local source or destination addresses. IPv4 link-local unicast addresses are assigned from address block ( through ). In IPv6, unicast link-local addresses are assigned from the block . Address assi ...

WS-Discovery
Web Services Dynamic Discovery (WS-Discovery) is a technical specification that defines a multicast discovery protocol to locate services on a local network. It operates over TCP and UDP port 3702 and uses IP multicast address or . As the name suggests, the actual communication between nodes is done using web services standards, notably SOAP-over-UDP. Various components in Microsoft's Windows Vista operating system use WS-Discovery, e.g. "People near me". The component WSDMON in Windows 7 and later uses WS-Discovery to automatically discover WSD-enabled network printers, which show in Network in Windows Explorer, and can be installed by double-clicking on them. In Windows 8 or later installation is automatic. WS-Discovery is enabled by default in networked HP printers since 2008. WS-Discovery is an integral part of Windows Rally technologies and Devices Profile for Web Services. The protocol was originally developed by BEA Systems, Canon, Intel, Microsoft, and WebMethods.

Discovery And Launch
Discovery and Launch (DIAL) is a protocol co-developed by Netflix and YouTube with help from Sony and Samsung. It is a mechanism for discovering and launching applications on a single subnet, typically a home network. It relies on Universal Plug and Play (UPnP), Simple Service Discovery Protocol (SSDP), and HTTP protocols. The protocol works without requiring a pairing between devices. It was formerly used by the Chromecast media streaming adapter that was introduced in July 2013 by Google. (Chromecast now uses mDNS instead of DIAL.) DIAL enables what the TV industry calls ''second screen'' devices, such as tablet computers and mobile phones to send content to ''first screen'' devices, such as televisions, Blu-ray players, and set-top boxes. Terminology and operation * 1st screen: a television, Blu-ray player, set-top-box, or similar device. * 2nd screen: a smartphone, tablet, or similar device. * DIAL Server: a device implementing the server side of the DIAL protocol, usually a 1st ...

Neighbor Discovery Protocol
The Neighbor Discovery Protocol (NDP), or simply Neighbor Discovery (ND), is a protocol of the Internet protocol suite used with Internet Protocol Version 6 (IPv6). It operates at the internet layer of the Internet model, and is responsible for gathering various information required for network communication, including the configuration of local connections and the domain name servers and gateways. The protocol defines five ICMPv6 packet types to perform functions for IPv6 similar to the Address Resolution Protocol (ARP) and Internet Control Message Protocol (ICMP) ICMP Router Discovery Protocol, Router Discovery and ICMP Redirect Message, Router Redirect protocols for IPv4. It provides many improvements over its IPv4 counterparts. For example, it includes Neighbor Unreachability Detection (NUD), thus improving robustness of packet delivery in the presence of failing routers or links, or mobile nodes. The Inverse Neighbor Discovery (IND) protocol extension allows nodes to deter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Zero-configuration Networking
Zero-configuration networking (zeroconf) is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite (TCP/IP) when computers or network peripherals are interconnected. It does not require manual operator intervention or special configuration servers. Without zeroconf, a network administrator must set up network services, such as Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS), or configure each computer's network settings manually. Zeroconf is built on three core technologies: automatic assignment of numeric network addresses for networked devices, automatic distribution and resolution of computer hostnames, and automatic location of network services, such as printing devices. Background Computer networks use numeric network addresses to identify communications endpoints in a network of participating devices. This is similar to the telephone network which assigns a string of digits to identify each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Jini
Jini (), also called Apache River, is a network architecture for the construction of distributed systems in the form of modular co-operating services. JavaSpaces is a part of the Jini. Originally developed by Sun Microsystems, Jini was released under the Apache License 2.0. Responsibility for Jini was transferred to Apache in 2007 under the project name "River", but the project was retired in early 2022 due to lack of activity. History Sun Microsystems introduced Jini in July 1998. In November 1998, Sun announced that there were some firms supporting Jini. The Jini team at Sun stated that ''Jini'' is not an acronym. Ken Arnold has joked that it means "Jini Is Not Initials", making it a recursive anti-acronym, but it has always been just ''Jini''. The word 'jini' means "the devil" in Swahili; this is borrowed from the Arabic word for a mythological spirit, originated from the Latin ''genius'', which is also the origin of the English word 'genie'. Jini provides the infrastruc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Service Location Protocol
The Service Location Protocol (SLP, srvloc) is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks. It has been defined in RFC 2608 and RFC 3224 as standards track document. Overview SLP is used by devices to announce ''services'' on a local network. Each service must have a URL that is used to locate the service. Additionally it may have an unlimited number of name/value pairs, called ''attributes''. Each device must always be in one or more ''scopes''. Scopes are simple strings and are used to group services, comparable to the ''network neighborhood'' in other systems. A device cannot see services that are in different scopes. The URL of a printer could look like: service:printer:lpr://myprinter/myqueue This URL describes a queue called "myqueue" on a printer with the host name "myprinter". The prot ...
