Research and design of the firewall penetration technology serving to distributed cloud resource

In current cloud systems, firewall penetration of distributed resource is a practical problem. Because this problem refers the existing TCP and UDP penetration schemes, we analyze all kinds of possible transmission environments in practical applications, and then present a technique to penetrate firewalls by UDP coordinating with TCP. Finally, we submit the implement frame of this method, a network switch --XIPSwitch, which is independent of various distributed cloud paradigms. The design can further solve the firewall penetration problem of the remote terminals of distributed cloud platform in the wide area network.
