  • Logical transport resource traffic management
    Patent number: 8139485
    Abstract: A method for managing data packets passing through an Ethernet node having multiple ingress ports and multiple egress ports, the ingress ports receiving the data packets from at least one service, and the egress ports configured with at least one Logical Transport Resource (LTR) configured as a predefined path between one of the egress ports and a destination in the Ethernet network. The method comprises mapping one or more of the services to each of the at least one LTR, shaping each of the at least one LTR to a configured rate, and transmitting data packets to the Ethernet network via the egress ports.

  • Carrier Ethernet with fault notification
    Patent number: 7839795
    Abstract: 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.
