An extranet is a controlled private computer network that allows communication with business partners, vendors and suppliers or an authorized set of customers. It extends intranet to trusted outsiders. It provides access to needed services for authorized parties, without granting access to an organization's entire network.
Schematic depicting an intranet. An intranet is a computer network for sharing information, easier communication, collaboration tools, operational systems, and other computing services within an organization, usually to the exclusion of access by outsiders. [1]
For example, an organization may provide access to some aspects of its intranet to share data with its business partners or customers. These other entities are not necessarily trusted from a security standpoint. The network connection to an extranet is often, but not always, implemented via WAN technology.
A telecommunications network is a group of nodes interconnected by telecommunications links that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching, message switching, or packet switching, to pass messages and signals.
An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
Connection-oriented transport-layer protocols provide connection-oriented communications over connectionless communication systems. A connection-oriented transport layer protocol, such as TCP, may be based on a connectionless network-layer protocol such as IP, but still achieves in-order delivery of a byte-stream by means of segment sequence numbering on the sender side, packet buffering, and ...
However, Kerberos does not work well over the internet due to the typical configuration of client-side firewalls. SSO to Microsoft backend systems in extranet scenarios is limited to the user id password mechanism. Based on the new feature called protocol transition using constrained delegation SAP developed the SSO22KerbMap Module.
A communication endpoint is a type of communication network node. It is an interface exposed by a communicating party or by a communication channel. An example of the latter type of a communication endpoint is a publish–subscribe topic [1] or a group in group communication systems. [2]
