Each participant can operate as a requestor or responder. The system also includes a network administrator that is configured to govern the flow of messages directly between participants. By interconnecting participants to an unlimited number of information providers, all participants can obtain information and verifications on an interactive basis. Also, by employing a single network having a standardized message format and protocol, all participants can quickly and easily interactively request or provide information and verify to any other participant without the concern of incompatibility between system, transmission, or even message formats or protocols.

A method and a system for digital content sharing between individual users in a peer-to-peer fashion, wherein each user is connected to a respective local access network through a transport network. The method and system provide local network storage areas associated with each user arranged for archiving digital contents, and carry out the transferring of contents via the transport network from a storage area associated with a user holding requested contents to a remote network storage area associated with a requesting user on a different access network according to the connectivity available on the transport network. The shared contents are made available for access by the requesting user on its local network storage area. A telecommunications network architecture includes the system so that there is a plurality of services of content sharing between pairs of individual users implementing the above method.

A transport system comprises a transport apparatus, which is used to construct a transport network using MPLS-TP; and a control apparatus for establishing a path in the transport network. The transport apparatus is coupled to a transfer apparatus, which is used to construct a transfer network using a network protocol different from an MPLS-TP protocol and uses the network protocol to establish a path in the transfer network in an autonomous distributed manner. The control apparatus and the transfer apparatus use the network protocol of the transfer network to transmit/receive, via the transport apparatus, control messages for controlling the transfer network. The transport apparatus avoids notifying the transfer apparatus of the fact that the control apparatus is not in a normal state, in a case where the path established in the transport network is determined as the normal state, even the control apparatus is determined as the abnormal state.

Methods and systems for providing necessary and sufficient quality-of-service (QoS), in a packet-based core transport network that utilizes dynamic setting of bandwidth management pipes or thresholds to obviate link congestion are disclosed. Congestion avoidance is a necessary and sufficient requirement in order to guarantee Quality of Service (QoS) in packet-based core networks.

A typical network is composed of a plurality of backbone links connecting edge nodes where backhaul links are aggregated. The backhaul links connect the backbone links to the remote sites serving the subscribers. In order to enforce bandwidth management policies, Access Controllers, which perform traffic shaping, are situated on each remote site.

In the event of a violation of certain link threshold settings, dynamic adjustment of the bandwidth management policies on affected Access Controllers is enforced. Various algorithms in determining the correlation between the link nearing congestion and the source or destination of traffic streams are also discussed. This invention implements a feedback control loop wherein probes at various points in the network checks for congestion states to guide bandwidth management threshold decisions in order to maintain the condition of non-congestion throughout the network. Capacity planning and congestion avoidance mechanisms work hand-in-hand to fulfill Service Level Agreements (SLA).

The invention includes a communication network for rotating media channels between resources of an emergency services network and a conforming emergency system (CES). A conforming emergency system and one of the resources of the emergency services network dynamically establish a first media channel between one another over a transport network. With the first media channel established, the conforming emergency system and the resource exchange messages over the first media channel to facilitate the CES in handling emergency events. Responsive to a triggering event, the CES and one of the resources (the same or another resource) dynamically establish a second media channel between one another over the transport network. With the second media channel established, the conforming emergency system and the resource exchange messages over the second media channel to facilitate the CES in handling emergency events. The first media channel may be torn down.

A method, apparatus and network for transporting layer-2 frames, such as Ethernet MAC, ATM AAL5, and Frame Relay, over SONET, SDH, or OTN transport networks is disclosed. The method establishes "pseudo-wires" between, for example, SONET switches and directly on top of the SONET layer. The method may implement MPLS signaling protocols on traditional SONET switches for the purpose of aggregating layer-2 frames from the transport network edges, while the transport network itself is independent from IP and MPLS routing. This approach provides a number of advantages to the network carriers in terms of operation and equipment expense reduction. To enable the transport network to be independent from IP and MPLS, and avoid subsequent IP control message processing inside the networks, an edge-to-edge "tunneling" mechanism is designed to transmit control messages as a part of the SONET (or SDH or OTN) frame payload.

Described is a process and system for providing an extensible forwarding plane data communications channel adapted to selectively support operations, administration and maintenance (OAM) activity within one or more different domains of an Ethernet transport network. The data communication channel is established using Ethernet protocol data units forwarded within the forwarding plane, between network elements. The Ethernet protocol data units can be Ethernet OAM frames modified to include an OpCode indicative of a maintenance communication channel. The OAM frames are generated at a selected one of the network elements (source), forwarded along the same network path as the Ethernet frames, and terminate at another network element (destination) associated with a maintenance level identified within the OAM frame. The source and destination network elements can reside on a domain boundary using the Ethernet OAM frames flowing therebetween to relay maintenance communications channel messages.

Simple peering is provided in a novel network in which transport technology is independent of network access technology. An out-of-band network may be used to carry advertisements to an update facility. The update facility may use layer 3 destination address information and at least a part of context information (to identify customers uniquely) to determine a layer 3 address of an edge device of the transport network associated with an addressed customer device. Virtual private networks are supported, as context information is used to distinguish different customers with overlapping layer 3 addresses.

A fully meshed telecommunications network based on an optical core transport network having a plurality of optical nodes is described. An electronic edge switch is connected to an optical node and dedicated channels are established between all the possible pairs of electronic edge switches through their associated optical nodes and the optical core transport network. Connection paths are set up using a channel or channels between a pair of electronic edge switches which perform major functions concerning connection routes, including rate regulation, path establishment, etc.

A transport LAN segment service is provided over a transport network. Responsibilities for configuring, provisioning and forwarding over a transport LAN segment are divided between layer 2 and 3 service provider edge devices, where the layer 3 edge device handles discovery and tunneling responsibilities, the layer 2 edge device handles learning and flooding responsibilities, and information can be exchanged between the layer 2 and 3 edge devices. Configuration is simplified by advertising TLS-label information, layer 2 address learning, and flooding when the needed configuration information has not yet been learned or discovered.
