Reinforcement learning-based SDN routing scheme empowered by causality detection and GNN.

In recent years, with the rapid development of network applications and the increasing demand for high-quality network service, quality-of-service (QoS) routing has emerged as a critical network technology. The application of machine learning techniques, particularly reinforcement learning and graph neural network, has garnered significant attention in addressing this problem. However, existing reinforcement learning methods lack research on the causal impact of agent actions on the interactive environment, and graph neural network fail to effectively represent link features, which are pivotal for routing optimization. Therefore, this study quantifies the causal influence between the intelligent agent and the interactive environment based on causal inference techniques, aiming to guide the intelligent agent in improving the efficiency of exploring the action space. Simultaneously, graph neural network is employed to embed node and link features, and a reward function is designed that comprehensively considers network performance metrics and causality relevance. A centralized reinforcement learning method is proposed to effectively achieve QoS-aware routing in Software-Defined Networking (SDN). Finally, experiments are conducted in a network simulation environment, and metrics such as packet loss, delay, and throughput all outperform the baseline.

A Study on Intelligent Tourism App Based on Artificial Intelligence

With the rapid development of science and technology and the rapid development of network applications, the Internet era has been promoted, and the popularity of smart phones has made great changes in people’s way of life. More and more rely on mobile phone applications to deal with the scale of life. At the same time, with the improvement of material living standard, people pay more attention to the pursuit of spiritual life, travel will become the perfect choice to relax body and mind, and smart phone tourism application (tourism app) is the basic way to realize intelligent tourism. The National Tourism Administration of the people’s Republic of China issued a holiday tourism information circular saying that during the 2012 Mid-Autumn Festival National Day Golden week, 119 scenic spots in the country received 34.2456 million tourists, an increase of 40.7 percent over the same period last year, and the number of tourism complaints increased significantly. Tourist satisfaction is not optimistic. Intelligent tourism is the inevitable trend of the development of tourism in the world, and strategic demand for the transformation and upgrading of tourism in China.

TRIP: A Tussle-Resistant Internet Pricing Mechanism

The rapid development of network applications has led to a dramatic demand on Internet capacity. In response, internet service providers are exploring new data pricing approaches as economic countermeasures. However, previous pricing schemes are inadequate to provide tussle-resistance property that enables confidential price propagation and accurate bandwidth accounting. In this letter, we propose tussle-resistant Internet pricing mechanism (TRIP), which is built upon border gateway protocol and involves multiple cryptographic algorithms for price encryption and dissemination. TRIP effectively accomplishes source authentication and price confirmation, and leverages network capability to achieve bandwidth allocation and accounting. We confirm the efficiency of TRIP via comprehensive experiments.

A path switching scheme for SCTP based on round trip delays

Due to the rapid development of network applications, today the Internet plays an important role in our everyday life. Users hope that the network is always speedy enough to help them access the Internet without any delay. But the real situation is far from the ideal case. In the future, network researchers will continuously improve the network speed, and try to develop networks that are robust, without any crashes or packet loss. In this paper, we propose an aggressive path switching scheme for SCTP. Before data transmission, the scheme selects the fastest path as the primary path to transmit packets. When the path fails or transmission quality is poor, this scheme evaluates alternate paths, and selects the one with the best quality as the new primary path to substitute for the original one. After that, packets are delivered through the new path. Several factors are considered in the evaluation, including bandwidth, encryption/decryption, size of the congestion window, retransmission policy, routing policy, etc.

Research and Implementation of Three HTTPS Attacks

W ith the rapid development of network applications , the issues of Network transmission security become very important. Therefore, SSL protocol is more and more widely used in a variety of network services . But the SSL protocol itself is not perfect, in practice, there are also problems. For the deficiencies of endpoint authentication in the SSL handshake process, the paper analyzes two kinds of defects existing in the SSL hand-shake process. Firstly, handshake process, in the first stage of the SSL connection, using plaintexts, existing the possibility of being monitored and tampered. Secondly, SSL deployment of the actual application. Because of considering the factors about the performance of the network connection, that usually uses the way of switch connection based on HTTP protocol. In response to these deficiencies, this thesis adopts the two ways of forged certificates and converting the data stream from HTTPS to HTTP to attack them. In addition, a new attack mode against the data stream of HTTPS is designed and implemented. Experiments show that the above three methods cause significant security risks to HTTPS communications. Therefore, taking a static ARP table, enhanced certificate mechanism and mutual authentication of three different measures are proposed to enhance network security in the paper. It is shown that three ways can relative effectively defense against attacks on HTTPS in the experiments.

Content delivery networks: a bridge between emerging applications and future IP networks

With the rapid development of network applications, the Internet has evolved from a content-based communication infrastructure to a social-based community network. The emerging applications require the Internet to preserve not only the existing advantages of simplicity and scalability, but also demand varying amounts of capability, availability, reliability, flexibility, and differentiated quality of service. Therefore, it is of paramount importance to bridge the gap between these applications and the IP networks which were originally designed and developed for supporting one-size-fits-all functionality. An efficient solution is to build a virtual network on top of a generic IP transport layer in order to provide additional functionality and flexibility. The content delivery networks technique is one of the successful virtual networks rapidly developed over the last decade with the specific advantage of optimizing the Internet. Nowadays, the CDN has become one of the most important parts of the Internet architecture for content distribution. In this article we highlight the innovative technologies in CDNs and present their evolution triggered by ever newer emerging applications. By presenting in-depth discussion about the architecture, challenges, and applications of CDNs, we demonstrate their importance for the future Internet.
