1993 results about "Goose" patented technology

A goose (plural geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera Anser (the grey geese), Branta (the black geese), and Chen (which includes the white geese); the latter being commonly placed within the genus Anser. Some other birds, mostly related to the shelducks, have "goose" as part of their names. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller.

Message accurate recognition-based substation communication network deterministic path switching method

The invention discloses a message accurate recognition-based substation communication network deterministic path switching method. The method comprises the following steps that: an IED at first needs to parse the APPID, SRCMAC and GOOSEID ref/smvID of GOOSE and SV messages; and then HASH computation is performed on the GOOSEID ref/smvID so as to form an ASH combination key; an ASH forwarding table is searched, when contents that completely conform to the APPID, SRCMAC and HASH (GOOSEID ref/smvID) of the massages exist in the ASH forwarding table, the massages directly go to corresponding ports in the ASH forwarding table, and when no corresponding information or information that is not completely corresponding to the APPID, SRCMAC and HASH of the messages exists in the ASH forwarding table, the messages are discarded; and finally, the messages enter a queue at the ports through cache mapping, and queue up for transmission, and at the same time, equipment continues to receive GOOSE and SV messages. With the message accurate recognition-based substation communication network deterministic path switching method of the invention, problem of conflicts in message recognition can be avoided; deterministic path forwarding of specified massages can be realized; and problems of network congestion and equipment misoperation caused by a multicast switching mode can be effectively alleviated.
