Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network, forming a peer-to-peer network of nodes . [ 1 ]
Overlay multicast is also known as End System or Peer-to-Peer Multicast. High bandwidth multi-source multicast among widely distributed nodes is a critical capability for a wide range of applications, including audio and video conferencing, multi-party games and content distribution.
A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel. [1] In data communication, a physical network node may either be data communication equipment (such as a modem , hub , bridge or switch ) or data terminal equipment (such ...
A personal area network (PAN) is a computer network used for communication among computers and different information technological devices close to one person. Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and video game consoles.
In peer-to-peer (P2P) content-delivery networks, clients provide resources as well as use them. This means that, unlike client–server systems, the content-centric networks can actually perform better as more users begin to access the content (especially with protocols such as Bittorrent that require users to share).
Position-based routing methods use information on the exact locations of the nodes. This information is obtained for example via a GPS receiver. Based on the exact location the best path between source and destination nodes can be determined. Example: "Location-Aided Routing in mobile ad hoc networks"
The lesser-known PSYC technology uses custom multicast strategies per conference. [6] Some peer-to-peer technologies employ the multicast concept known as peercasting when distributing content to multiple recipients. Explicit multi-unicast (Xcast) is another multicast strategy that includes addresses of all intended destinations within each packet.
Other examples of point-to-point communications links are leased lines and microwave radio relay. The term is also used in computer networking and computer architecture to refer to a wire or other connection that links only two computers or circuits, as opposed to other network topologies such as buses or crossbar switches which can connect ...
