In Named Data Networking (NDN), data synchronization plays an important role similar to transport protocols in IP. Many distributed applications, including pub-sub applications such as news and weather services, require a synchronization protocol where each consumer can subscribe to a different subset of a producer's data streams. However, existing Sync protocols support only full-data synchronization,...
Featured by public IPv4 address sharing with port restriction, aplusp concept is proposed as a solution for providing IPv4 continuity in IPv6-enabled networks. This paper proposes an approach called aplusplite, which is capable of implementing reliable high performance network and service in a straightforward and cost-effective way, as well as encouraging IPv6 deployment.
Public IPv4 sharing solutions with port restriction alleviate IPv4 address depletion problem and encourage IPv6 deployment. This paper proposes extensions to the Internet Gateway Device control standardized in the UPnP Forum to efficiently solve the port reservation failure problem in an IPv6 access network environment that adopts a public IPv4 sharing mechanism, i.e., a public IPv4 address is shared...
A recent trend in Internet denial-of-service attacks is to distribute the attack sources among a large number of compromised computers. To effectively control such attacks, the attack traffic must be stopped at an early stage, which means those edge networks that host the attack sources must be given proper incentives and mechanisms to stop undesirable traffic. We previously proposed an architecture...
In order to realize network functions of information appliances, after analyzing the feasibility of transplanting LwIP to embedded operating system according to the requirement of information appliances under IPv6 network, we built an information appliance development platform on ARM920T processor and VxWorks, transplant open source network protocol LwIP to the MUX layer of VxWorks to implement IPv6...
In this paper, we propose a MAC layer multicast protocol for 802.11n WLAN for the first time. In IEEE 802.11n, new feature at MAC layer, such as frame aggregation and more flexible link adaptation are defined to increase the effective throughput. Recently, several multicast protocols at MAC layer have been proposed for WLAN. However, these protocols don't consider the new features defined in 802.11n,...
In IEEE 802.11, multicast protocol is based on the basic access procedure of Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). This protocol does not provide any recovery mechanism for multicast frames. As a result, transmitted multicast frames may be lost due to collisions or errors. Recently, several reliable multicast protocols at MAC layer have been proposed for 802.11. They can...
We address the security vulnerabilities in existing protocols for network traffic authentication, by engaging edge networks in defending against undesirable traffic. In the proposed PATRICIA architecture, edge networks cooperate to prevent misbehaving sources from flooding traffic in both control and data channels. Moreover, edge networks employ an endorsement procedure to approve data communications...
