SOURCE ADDRESS VALIDATION TECHNOLOGY
This Source Address Validation Technology was the first put forward anywhere in the world, which promoted the establishment of IETF international standards.
The challenges of Source Address Validation Technology
Router does not save path information (forwarding without connection and storage).
Routing selection policies are real-time dynamic change and diverse (best-effort routing selection).
Routing algorithms are different in different levels (routing algorithms are not unified in the whole Internet).
Source Address Validation Technology-SAVA
The source address verification architecture and different granularity verification methods for access network, intra-domain and inter-domain are proposed.
The source address verification for the whole Internet, accurate location and traceability are implemented.
Innovation point 1
Source Address Verification Architecture (SAVA) for Internet.
Innovation point 2
Address state dynamic synchronization based source address verification algorithm for access network.
Innovation point 3
Legitimate path calculation based source address verification mechanism for Intra-domain.
Innovation point 4
Trust relationship delivery based source address verification protocol for Inter-domain.
