Patents

  • Smart ethernet edge networking system

    Issued US 8509062

    A telecommunications system includes a network for transporting packets on a path between selected subscriber end points. The network has multiple nodes connected by links, with each node (a) pairing the forward and backward paths of a connection and (b) allowing for the injection of messages in the backward direction of a connection from any node in the path without needing to consult a higher OSI layer. A system is also provided for protecting connection paths for transporting data packets…

    A telecommunications system includes a network for transporting packets on a path between selected subscriber end points. The network has multiple nodes connected by links, with each node (a) pairing the forward and backward paths of a connection and (b) allowing for the injection of messages in the backward direction of a connection from any node in the path without needing to consult a higher OSI layer. A system is also provided for protecting connection paths for transporting data packets through an Ethernet telecommunications network having a multiplicity of nodes interconnected by a multiplicity of links. Primary and backup paths are provided through the network for each of multiple connections, with each path including multiple links. Data packets arriving at a first node common to the primary and backup paths are duplicated, and one of the duplicate packets is transported over the primary path, the other duplicate packet is transported over the backup path, and the duplicate packets are recombined at a second node common to the primary and backup paths.

  • Smart Ethernet edge networking system

    Issued US 8363545

    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…

    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.

  • Carrier Ethernet with fault notification

    Issued US 7839795

    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…

One type of service protection action is protection switching.

Projects

  • JNET-to-ENET Retrofit Outage Reduction

    -

    Reduced planned outage required to upgrade a DMS network component from the legacy physical JNET to the electronic ENET. The initial process required a call processing outage of 15 minutes. A new process was developed and tested that required an outage of only 2 minutes.
