In the design and construction process of Next Generation Internet, it is important to identify the source of each IP packet forwarding accurately, especially for the support of precise fine-grained management, control, traceability and improving the trustworthiness of the Internet. This paper designed a scalable Network Identity (NID) scheme for the Internet users, proposed NIDTGA (Network Identity and Time Generated Address), an IPv6 address generation algorithm embedded NID and time information, then designed and implemented an IPv6 address generation and traceback system based on NIDTGA. The design of NIDTGA, which reflects the length, time and owner attributes of the IP address, can be a good support to ADN (Address Driven Network). At the same time, by embedding the key elements of user identity and time in the IPv6 address, and by taking into account both the traceability and privacy, NIDTGA can provide a technical basis for the establishment of the network trust mechanism, and achieve the traceability of security event.

IP source address spoofing is regarded as one of the most prevalent components when launching an anonymous invasion, especially a Distributed Denial-of-Service (DDoS) attack. Although Source Address Validations (SAVs) at the access network level are standardized by the Internet Engineering Task Force (IETF), SAV at the inter-Autonomous System (AS) level still remains an important issue. To prevent routing hijacking, the IETF is constructing a Resource Public Key Infrastructure (RPKI) as a united trust anchor to secure interdomain routing. In this study, we creatively use the RPKI to support inter-AS SAV and propose an RPKI-based Inter-AS Source Protection (RISP) mechanism. According to the trust basis provided by the RPKI, RISP offers ASes a more credible source-oriented protection for the IP addresses they own and remains independent of the RPKI. Based on the experiments with real Internet topology, RISP not only provides better incentives, but also improves efficacy and economizes bandwidth with a modest resource consumption.

In the environment of omni-media era with new media technology as the mainstream information communication channel, the Cross-border marketing method of IP industry and makeup joint name can not only enhance brand visibility and visibility, but also strengthen the value of brand image, which has a positive effect on the development of I P and the brand itself. However, the joint-branded market has hidden dangers and chaos. In the process of rapid development, the compatibility of the Co-branded products; the emergence of frequent Co-branded products makes aesthetic fatigue for consumers; and the quality and price of the Co-branded products are uneven. Not only did not achieve the expected income, but also caused some damage to the image of the joint parties. This paper takes the joint name of M · A · C and King of Glory as an example to analyze and study the problems existing in Cross-border marketing and provide marketing suggestions for the development of IP Cross-border marketing activities.
