  • Distributing ethernet alarm indication signal information to multiple virtual local area networks
    Patent number: 8547832
    Abstract: Ethernet Alarm Indication Signal (ETH-AIS) information for multiple Virtual Local Area Networks (VLANs) is consolidated and distributed to the multiple VLANs in a single Ethernet frame. Note, as used herein, “Alarm Indication Signal (ETH-AIS)” refers to an IEEE 802.x or ITU-T Y.1731 Ethernet Alarm Indication Signal. A device receiving the Ethernet frame with the consolidated ETH-AIS information typically forwards the frame out each port that communicates traffic for one of the VLANs included in the consolidated ETH-AIS information.
    Type: Grant
