网络，随处而上

我们这一代，没有怎么经历过长辈们的那些艰难动荡的时期，却在科学技术发展的历程当中成为了重要的关注者与参与者。     

去中心化互联网基础设施

域间路由系统、域名系统和公钥基础设施等是互联网重要的基础设施,它们是互联网的网络连通性、服务可用性和通信可信性的基础。然而,这些基础设施或其背后的可信模型是中心化的,存在着中心节点权限过大、单点失效等脆弱性,降低了互联网的安全性、可靠性和平等性。为了构建一个更加安全、可靠、平等和开放的互联网,尝试提出了去中心化的互联网基础设施（decentralized internet infrastructure,DII）,并讨论其体系结构和各层的设计,分析系统的可行性。DII架构包含3个层次：底层利用分布式账本技术构建基础的去中心化能力;中间层构建IP地址和域名等互联网名字空间的去中心化可信管理机制,并支持安全可信的域间路由和域名映射系统;顶层为开放的应用层,支持和促进创新、可信的去中心化互联网应用。     

Securing the wireless internet

Internet-enabled wireless devices continue to proliferate and are expected to surpass traditional Internet clients in the near future. This has opened up exciting new opportunities in the mobile e-commerce market. However, data security and privacy remain major concerns in the current generation of "wireless Web" offerings. All such offerings today use a security architecture that lacks end-to-end security. This unfortunate choice is driven by perceived inadequacies of standard Internet security protocols like SSL on less capable CPUs and low-bandwidth wireless links. This article presents our experiences in implementing and using standard security mechanisms and protocols on small wireless devices. We have created new classes for the Java 2 Micro-Edition platform that offer fundamental cryptographic operations such as message digests and ciphers as well as higher level security protocols like SSL. Our results show that SSL is a practical solution for ensuring end-to-end security of wireless Internet transactions even within today's technological constraints     

Advances in internet congestion control

In this survey, we first review the concept of congestion control with a focus on the Transmission Control Protocol⁄Internet Protocol (TCP⁄IP). We describe many recently proposed algorithms to combat congestion and improve performance, particularly active queue management (AQM) algorithms such as random early detection (RED) and its variants. We then survey control-theoretic analysis and design of TCP congestion control with an AQM scheme. In addition, we discuss three problems associated with AQM proposals: parameter setting, the insensitivity to the input traffic load variation, and the mismatch between macroscopic and microscopic behavior of queue length dynamics. As alternatives to AQM algorithms, we also survey architectural approaches such as modification of source or network algorithms, and economic approaches including pricing or optimization of allocated resources. Finally, we list many open issues that persist in the design, operation, and control of the Internet.

Hybrid internet traffic classification technique

Accurate and real-time classification of network traffic is significant to network operation and management such as QoS differentiation, traffic shaping and security surveillance. However, with many newly emerged P2P applications using dynamic port numbers, masquerading techniques, and payload encryption to avoid detection, traditional classification approaches turn to be ineffective. In this paper, we present a layered hybrid system to classify current Internet traffic, motivated by variety of network activities and their requirements of traffic classification. The proposed method could achieve fast and accurate traffic classification with low overheads and robustness to accommodate both known and unknown/encrypted applications. Furthermore, it is feasible to be used in the context of real-time traffic classification. Our experimental results show the distinct advantages of the proposed classification system, compared with the one-step Machine Learning (ML) approach.
