A system is provided for controlling the flow of data-packet traffic through an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links. Incoming data-packet traffic from multiple customer connections are received at a first node for entry into the network via the first node. Flow control messages are generated to represent the states of the first node and, optionally, one or more network nodes upstream from the first node, and these states are used as factors in controlling the rate at which the incoming packets are admitted to the network. Alternatively, the flow control messages may be used to control the rate at which packets generated by a client application are transmitted to the first node.

Smart Ethernet edge networking system

A forwarder for use within an internetworking system operating over an ATM backbone is provided. The physical internetworking devices within the system are shared to provide the internetworking functions while servicing two or more distinct and isolated user networks. This is accomplished by logically partitioning the devices into distinct sub-elements which provide all or part of the internetworking functions. These sub-elements are uniquely allocated to independent realms which are then assigned to specific user networks.

Method and apparatus for forwarding packets

A method of controlling the flow of data packet traffic from a first point to at least two second point in an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links, comprises monitoring the level of utilization of a link between the first and second points, generating flow control messages representing the level of utilization and transmitting the control messages to the first point, and using the states represented in the flow control messages as factors in controlling the rate at which the packets are transmitted from the first point to the second point. A method of controlling the flow of data packet traffic through an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links, comprises receiving incoming data packet traffic from multiple customer connections at a first node for entry into the network via the first node, the first node having an ingress trunk, and limiting the rate at which the incoming data packets are admitted to the network via the ingress trunk.

Efficient ethernet LAN with service level agreements

A method of testing a service connection within a container in an Ethernet network comprises coupling a test device to a port on a node in a path that includes the container, switching traffic of the service connection to the port, measuring selected parameters of the switched traffic in the test device, and using the measured parameters to evaluate the performance of the service connection. In one implementation, the switching uses service and container identifications, and switching the traffic to the test device is based on the service and container identifications. The test device may be capable of inserting traffic within the service connection, and the container may be a tunnel.

A system and method for the collection, analysis, utilization, and/or reporting of user preference of content experienced by the user preferably for managing the distribution network of a content delivery environment, managing the selections of content available, reporting user selections of content available, and/or execution of user instructions as presented in the content.

Apparatus and method for the collection and utilization of user selection in a content delivery environment

A method of fault notification in a carrier Ethernet having the capability of generating and transmitting OAM packets having flag fields, comprises inserting a bit in one of the flag fields to indicate the presence of service-affecting information in the OAM packets, detecting the presence of the inserted bit at the end of a data path, and performing a service protection action in response to the detection of the inserted bit prior to parsing the information in the message. One type of service protection action is protection switching.

Carrier Ethernet with fault notification

A system is provided for making connections in a telecommunications system that includes a network for transporting communications between selected subscriber connections, and a wireless network for coupling connections to the network. The network and wireless network are interfaced with a traffic management element and at least one radio controller shared by connections, with the traffic management element and the radio controller forming a single integrated network element. Connections are routed from the wireless network to the network via the single integrated network element.

Smart ethernet mesh edge device

A method and apparatus for adaptive service interworking include processing that begins by obtaining connection information of a receiving end-point network switch in response to receiving a setup message from a sending party. The setup message identifies a receiving party, which is operably coupled to the receiving end-point switch. Such connection information may be obtained by sending an enhanced traffic descriptor appended to the setup message and receiving an enhanced traffic descriptor that was appended to a connection message from the receiving end-point switch. The connection information is then interpreted to determine whether the receiving end-point switch is capable of supporting a transparent link. If the end-point network switch is capable of supporting the transparent link, the transparent link is established and utilized to transport data between the sending and receiving parties.
