Practical Migration Strategy to IPv6 for Enterprise Web Services

摘要

For migration of enterprise Web services from IPv4 to IPv6, just making a Web server ready for IPv6 is a weak solution that raises serious problems. For example, users experience errors when they request services that have not yet supported IPv6. In addition, the solution requires that the organization network be protected from malicious IPv6 accesses, although there are no total security solutions for IPv6 such as a firewall. To address these issues, we have developed a high performance IPv6-enabled reverse proxy server that provides practical migration strategy to IPv6 for enterprise Web services. The key techniques there include an efficient memory-based cache algorithm especially for reverse proxies and a flexible service filter that allows administrators to manage services intensively for both IPv4 and IPv6. Our reverse proxy server also provides good conformity to the current IPv4 security framework.
