New routing algorithms in trustworthy Internet

Since the lack of source IP address checking in today’s Internet makes it easy for the attackers to spoof the source address, the mechanism of Source Address Validation Architecture (SAVA) is proposed for building effective source-address validation to ensure that packets forwarded hold authentic source addresses. In this paper, we study the routing selection in partial deployment of SAVA nodes in the trustworthy Internet. We propose and compare three routing algorithms, i.e., Shortest-Path Algorithm (SPA), SAVA based Shortest-Path Algorithm (SSPA), and SAVA based Shortest-Path Algorithm with Load Balancing (SSPALB). Beside analytical results, we run simulations which met our expectations.
