COMMUNICATION SYSTEM, COMMUNICATION METHOD, NETWORK DEVICE AND PROGRAM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18028105 Titled 'COMMUNICATION SYSTEM, COMMUNICATION METHOD, NETWORK DEVICE AND PROGRAM'
Simplified Explanation
The present disclosure describes a communication system that connects a first network and a second network through multiple paths. The system includes a transfer prevention unit that stops the transfer of broadcast frames, unknown unicast frames, and multicast frames from the second network to the first network. Instead, these frames are only transferred from the second network to the first network through a specific path among the multiple paths. The purpose of this system is to enable the transfer of unicast frames via a nearby boundary apparatus, even when communicating from an L2 network to an EVPN, and to avoid the overlapping distribution of BUM (Broadcast, Unknown unicast, and Multicast) frames.
Original Abstract Submitted
An object of the present disclosure is to transfer unicast via a boundary apparatus that is geographically close to a user apparatus even in communication from an L2 network to an EVPN and to prevent overlapping distribution of BUM. According to the present disclosure, there is provided a communication system in which a first network and a second network are connected to each other by a plurality of paths, in which, in the plurality of paths, a transfer prevention unit that prevents transfer of a broadcast frame, an unknown unicast frame, and a multicast frame from the second network to the first network is included, and in which a broadcast frame, an unknown unicast frame, and a multicast frame are transferred from the second network to the first network by only a specific path of the plurality of paths.
