Systems and methods for connecting and configuring a communication network are described. A network includes a first router; a tie-line having a plurality of full duplex dedicated router interconnects connected to said first router; a second router connected to said plurality of full duplex dedicated router interconnects; a first user connected to said first router with a first full duplex loop; and a second user connected to said second router with a second full duplex loop. The systems and methods provide advantages in that bursty control information can be multiplexed with time sensitive laminar data.

A method and system is provided in which data packets from multiple customer VLANs are forwarded over a MAN using VLAN aggregation. A layer-2 switch located at the edge of the MAN connects the customer VLANs to the MAN. The edge switch aggregates multiple customer VLANs (the “sub-VLANs”) into one provider VLAN (the “super-VLAN”). When a packet is forwarded from the sub-VLAN to the super-VLAN and vice versa, the edge switch uses modified bridge forwarding rules to exchange the customer-configured VLAN-IDs with the provider-configured VLAN-IDs before transporting the packet over the MAN. The edge switch further uses modified bridge media access control (MAC) address learning rules to isolate one customer's traffic from another's (i.e. isolate one sub-VLAN's traffic from another sub-VLAN's traffic).

The present disclosure provides for creating a metropolitan mesh network using vehicles as the framework. Mobile access points are installed on vehicles and configured to create ad-hoc, self-healing networks using mesh technology.

The present invention provides a system and method for maintaining and displaying information regarding high bandwidth telecommunication cables in metropolitan areas. The present invention allows a user to select a metropolitan area for display. The user may thereafter select one or more vendors who own high bandwidth telecommunication cables in the selected metropolitan area. A user may control the prominence of displayed cables by designating selected vendors in a prioritized list.

A method and system for implementing weighted fair flow control on a metropolitan area network. Weighted fair flow control is implemented using a plurality of metro packet switches (MPS), each including a respective plurality of virtual queues and a respective plurality of per flow queues. Each MPS accepts data from a respective plurality of local input flows. Each local input flow has a respective quality of service (QoS) associated therewith. The data of the local input flows are queued using the per flow queues, with each input flow having its respective per flow queue. Each virtual queue maintains a track of the flow rate of its respective local input flow. Data is transmitted from the local input flows of each MPS across a communications channel of the network and the bandwidth of the communications channel is allocated in accordance with the QoS of each local input flow. The QoS is used to determine the rate of transmission of the local input flow from the per flow queue to the communications channel. This implements an efficient weighted bandwidth utilization of the communications channel. Among the plurality of MPS, bandwidth of the communications channel is allocated by throttling the rate at which data is transmitted from an upstream MPS with respect to the rate at which data is transmitted from a downstream MPS, thereby implementing a weighted fair bandwidth utilization of the communications channel.

A community network system with broadband integrated services includes video servers, video storages, video conference servers, satellite digital television receiver servers, a network accounting server, a network management server, Gigabit Ethernet Switches, Fast Ethernet switches, home gateways, wireless gateways, digital television sets, analogue television sets, computers, PCs with wireless interface, stationary IP telephones, and wireless IP mobile phones. The IP stationary phone can be connected between the Fast Ethernet switch and the home gateway, and also can be connected between the home gateway and the computer. The wireless gateway is connected to the mobile phone and a mobile device. The satellite digital television receiver server is connected to a satellite signal receiver antenna. The backbone Gigabit Ethernet Switch is connected to a Metropolitan Area Network via a 1000 Mbps or 100 Mbps port. The system simultaneously provides the services of digital television, Internet access of the computer and IP telephone. The present invention achieves the service integration of television network, telephone network and computer network, and the integration of wired and wireless networks, and ensures the qualities of various services, information security and reasonable accounting.

An emergency alert system for alerting DSL subscribers of imminent perils includes an alert server connected over a direct link to an edge node of a metro network for receiving an event notification, configuring from an event notification a highest priority alert message, and broadcasting the alert message to subscriber terminals over the metro network. An add multiplexer (ADM) multiplexes the alert traffic with the regular traffic onto the direct link, anthe multiplexed traffic reaches the edge node of the metro network, which is configured with a high priority policy. The edge node discards the lower priority traffic in the presence of the alert traffic and an applet installed on said subscriber terminal accepts and displays the alert message in a browser or a media player.

The invention relates to a backbone network system based on quantum communication and a relay method thereof. According to the method, key relaying is performed between the access nodes of all the metropolitan area networks of the backbone network in advance according to a certain strategy so that the access nodes of all the metropolitan area networks are enabled to perform secret communication byusing the relay key; at least one server side is set for the access nodes and the relay nodes, and the access nodes periodically and automatically initiate relaying to other access nodes; the respective key management terminal of the access nodes and the relay nodes periodically reports the calculated key amount to the connected server side; and the server side respectively generates a quantum routing table and a relay routing table according to different shared key amount types and calculates the path key amount to be issued to the access nodes and the relay nodes, and each access node performs automatic relaying according to the routing table and the path key amount acquired from the server side.

The optimization method for P2P application in MAN comprises: a. when requiring downloading some resource, calling this P2P node as the request P2P node; b. searching the P2P index server to find out the P2P node list included the target resource, and calling as resource P2P node; c. from resource P2P node list, finding out the one with shortest distance with the request P2P node; and d. downloading target resource from one or more resource P2P nodes. Compared with prior art, this invention limits P2P flow on network edge as far as possible, can avoid network congestion led by P2P business, and fit to spread widely.
