Abstract
The present invention is directed to novel mechanisms for discovery and integrity testing in an Ethernet domain that can span one or more Ethernet service providers.
Claims10
A method of administering an ethernet domain, the method comprising the steps of:
- sending a query from a first Ethernet node in the Ethernet domain to a second Ethernet node in the Ethernet domain, the query requesting virtual local area network configuration information from the second Ethernet node;
- receiving a response from the second Ethernet node, the response comprising the virtual local area network configuration information which further comprises a data field containing information on virtual local area networks configured on a shared tagged link between the first Ethernet node and the second Ethernet node.
A method of administering an Ethernet domain, the method comprising the steps of:
- broadcasting a query in a virtual local area network format to one or more stations connected to an Ethernet domain, the query requesting Ethernet configuration information from the stations;
- and
- receiving responses from the stations, the response comprising a data field containing the Ethernet configuration information from the stations and where the query must traverse an untagged boundary of the Ethernet domain, translating the query from the virtual local area network format into a protocol data unit that does not utilize virtual local area network tagging.
A method of administering an Ethernet domain, the method comprising the steps of:
- receiving an OAM request from a first host in the Ethernet domain addressed to a second host in the Ethernet domain;
- where the OAM request is traversing a tagged boundary in the Ethernet domain, encapsulating the OAM request in a virtual local area network format;
- where the OAM request is traversing an untagged boundary in the Ethernet domain, translating the OAM request from the virtual local area network format into a protocol data unit that does not utilize virtual local area network tagging;
- and
- forwarding the OAM request towards the second host in the Ethernet domain.
