An identified transport layer mechanism in the locator/identifier separation context

The traditional network design puts little emphasis on security and management of the transport layer mechanisms. However, new applications requiring security such as on-line bank and on-line shopping emerge sharply. Besides, various new applications induce the problem of management for pricing, reliability and resource distribution. Hence, a secure and manageable transport layer mechanism is significant and urgent under these occasions. In this paper, we propose an identified transport layer mechanism (ITM) in the locator/identifier separation protocol (LISP) context. ITM employs mapping cache to manage the packet transmitting process and separates host identifiers from the port numbers in the transport layer. Based on this mechanism, we can achieve enhanced security and management of the network transport layer.
