Embodiment Construction
[0045] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0046] The relevant technical means of this application are applied to such as figure 1 In the star satellite network topology shown.
[0047] When one of the end stations lan side receives an Ethernet message to be sent, the Ethernet message includes any one of broadcast, multicast or unknown unicast message, learns the source MAC address of the message, and then sends it to the satellite side. After the message sent by the end station is received and transferred by the central station, it will be sent to the satellite again, and all the end stations connected to the satellite network will receive the message, but for the end station that originally sent the Ethernet message , this part of the message should not be transmitted backwards, so it needs to be processed effectively.
[0048] Such as figure 2 The above is the first embodiment of the present applicatio...
