Considerations on the Security of IP based Telecommunication Network and its Architecture

摘要

We consider the security (DOS in particular) of the IP telephony network and how to constitute the next generation telephone network. First we discuss DOS attacks against Internet IP telephones, DOS attacks against the MPLS network for IP transfer, and then an IP network that has the ability to prevent DOS attacks. Last, we discuss the problems created by the disparity between the telephone number system E.164 and that of ENUM. We conclude by describing the idea of a more secure IP telephony network that prevents DOS attacks.
