Based on the SSM and ASM IPv6 bi-directional conversion method and system

The present invention provides a bi-directional converter ASM and the SSM method and system based on IPv6, the method comprising the steps of: S1: IPv6ASM bidirectional converter and the SSM initialization; S2: receiving a user request converter; if SSM is a conversion request to ASM , the process proceeds to step S3; if SSM is application to the ASM conversion, the process proceeds to step S4; if neither ASM conversion request is not to SSM SSM conversion to ASM application, the application is rejected; S3: to be IPv6ASM multicast group IPv6SSM sowing conversion; S4: IPv6SSM be multicast to IPv6ASM multicast conversion. According to the present invention is applied for the conversion information IPv6ASM multicast and multicast IPv6SSM bidirectional converter, able to convert the multicast IPv6SSM IPv6ASM multicast packet but can be from a plurality of sources IPv6ASM multicast converting a plurality of different source addresses but the same IPv6SSM multicast group multicast.
