Problem Statement, Gap Analysis, and Requirements for Intra-domain Source Address Validation

Problem Statement, Gap Analysis, and Requirements for Intra-domain Source Address Validation Zhongguancun Laboratory Tsinghua University Tsinghua University Zhongguancun Laboratory Huawei Source address validation (SAV) is an important means to mitigate IP source address spoofing [RFC2827]. This document analyzes the gaps in current operational mechanisms for intra-domain SAV. It also identifies the properties that new intra-domain SAV mechanisms are expected to provide.
