The current Internet is suffering from IPv4 address depletion. Stateless NAT64 is proposed to facilitate the IPv4/IPv6 co-existence and transition. In the past, the stateless NAT64 is mainly for IPv6 clients to access both IPv6 and IPv4 servers. As the fast growth of IP address consuming Internet services, the support for pure IPv6 servers is becoming urgent. In this paper, we propose a design of...
In the current Internet, IP address system suffers from the overloading of semantics. This brings great challenge to the scalability of the routing system and the mobility of network hosts. One proposal called Locator/ID separation which separates network layer into locater layer and ID layer has been discussed within the IETF and IRTF for years. In the meantime, the Internet is going through a phase...
IPv4 addresses are already depleted in IANA and will be soon exhausted in RIR while more clients are pouring into the Internet. IPv6, as the only available next generation Internet protocol, is still not commercially successful because a scheme that could solve the migration of IPv4 resources to IPv6 network, as well as mutual communication between the two incompatible protocols, has not been fully...
Based on the transit behavior, we categorize the Internet backbones into two types, global-transit backbone and partial-transit backbone. Partial-transit backbone represents the majority of R&E (Research & Education) backbones, which is liable to a number of inter-domain routing problems due to its particular characteristics. Through two routing cases in TEIN2 backbone, a typical R&E partial-transit...
We present an Internet-scale network topology information (NTI) service named WIND for localizing P2P traffic. Central to WIND are the two simple ideas: 1) obtaining NTI directly from routing infrastructures, and 2) leveraging existing, widely deployed DNS caches for NTI delivery. WIND fulfills the fidelity, flexibility and scalability requirement of an effective NTI service. WIND is deployed in CERNET...
IPv4 addresses will be soon exhausted while more and more users are pouring into the Internet. It is commonly understood that IPv6 is definitely necessary for connecting new users, but lack of resources in current IPv6 world discourages providers from developing their IPv6 market. Address and packet translations are considered necessary for Internet content resources migrating from IPv4 world to IPv6,...
