REsource LOcation And Discovery Framing
REsource LOcation And Discovery (RELOAD) is a peer-to-peer (P2P) signalling protocol for use on the Internet. A P2P signalling protocol provides its clients with an abstract storage and messaging service between a set of cooperating peers that form the overlay network. RELOAD is designed to support a peer-to-peer SIP network, but can be utilized by other applications with similar requirements by defining new usages that specify the kinds of data that must be stored for a particular application. RELOAD defines a security model based on a certificate enrollment service that provides unique identities.

Peer-to-peer
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. They are said to form a peer-to-peer network of nodes. Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Peers are both suppliers and consumers of resources, in contrast to the traditional client–server model in which the consumption and supply of resources are divided. While P2P systems had previously been used in many application domains, the architecture was popularized by the file sharing system Napster, originally released in 1999. The concept has inspired new structures and philosophies in many areas of human interaction. In such social contexts, peer-to-peer as a meme refers to the egalitari ...

Signaling Protocol
A signaling protocol is a type of communications protocol for encapsulating the signaling between communication endpoints and switching systems to establish or terminate a connection and to identify the state of connection. The following is a list of signaling protocols: * ALOHA * Digital Subscriber System No. 1 (EDSS1) * Dual-tone multi-frequency signaling * H.248 * H.323 * H.225.0 * Jingle * Media Gateway Control Protocol (MGCP) * Megaco * Regional System R1 * NBAP (Node B Application Part) * Signalling System R2 * Session Initiation Protocol * Signaling System No. 5 * Signaling System No. 6 * Signaling System No. 7 * Skinny Client Control Protocol (SCCP, ''Skinny'') * Q.931 * QSIG QSIG is an ISDN based signaling protocol for signaling between private branch exchanges (PBXs) in a private integrated services network (PISN). It makes use of the connection-level Q.931 protocol and the application-level ROSE protocol. ISDN "pr ... Network protocols Telephony signals ...

Peer-to-peer SIP
Peer-to-peer SIP (P2P-SIP) is an implementation of a distributed voice over Internet Protocol (VoIP) or instant messaging communications application using a peer-to-peer (P2P) architecture in which session control between communication end points is facilitated with the Session Initiation Protocol (SIP). SIP in a P2P architecture In a pure peer-to-peer application architecture no central servers are required, whereas traditional SIP telephony networks have relied on using centrally deployed and managed SIP servers, in analogy to the centralized switching architecture of the public switched telephone network (PSTN).RFC 3261, ''SIP: Session Initiation Protocol'', J. Rosenberg, H. Schulzrinne, G. Camarillo, A. Johnston, J. Peterson, R. Sparks, M. Handley, E. Schooler, The Internet Society (June 2002) P2P application design can improve scalability and survivability in the event of central network outages. The Session Initiation Protocol is in principle a client-server protocol, ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NAT Traversal
Network address translation traversal is a computer networking technique of establishing and maintaining Internet protocol connections across gateways that implement network address translation (NAT). NAT traversal techniques are required for many network applications, such as peer-to-peer file sharing and Voice over IP. Network address translation NAT devices allow the use of private IP addresses on private networks behind routers with a single public IP address facing the Internet. The internal network devices communicate with hosts on the external network by changing the source address of outgoing requests to that of the NAT device and relaying replies back to the originating device. This leaves the internal network ill-suited for hosting servers, as the NAT device has no automatic method of determining the internal host for which incoming packets are destined. This is not a problem for general web access and email. However, applications such as peer-to-peer file sharing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
