Rapid development has been witnessed in optimizing the performance of data centers over the past decade. However, such advances thriving in private data centers are rarely deployed in public-facing data centers. A major challenge is synchronizing optimization signals-such as flow sizes, server assignments, and load information-with the traffic they are intended to optimize, especially across networks controlled by different entities. In this paper, we propose CLOUDCOOKIE, a versatile signal carrier within internet protocols that ensures bidirectional signal presence without client-side cooperation. To exemplify CLOUDCOOKIE's benefits on public-facing data center traffic, we design a set of easy-to-deploy data center infrastructures, including load balancers and switches, to leverage application layer awareness and enable efficient flow packet scheduling and load balancing. Our evaluation shows that these advances synergistically optimize the 99(th) percentile of flow completion time by up to 20x for the majority of flows.

internet routers are a commons. While modest regulatory measures have generally been successful for Information Communication Technologies (ICT), this paper argues that the lack of regulation has hindered the technological evolution of the internet in some areas. This issue is examined through five internet problems, and the technological solutions adopted. The key contribution of this paper is the explanation of these issues and the identification of areas where misaligned incentives promote inadequate solutions or inaction. The paper reviews the available measures to encourage the adoption of globally beneficial internet technologies.

Industrial control protocols in the internet core: Dismantling operational practices

INTERNATIONAL JOURNAL OF NETWORK MANAGEMENT 2022年第1期32卷

Industrial control systems (ICS) are managed remotely with the help of dedicated protocols that were originally designed to work in walled gardens. Many of these protocols have been adapted to internet transport and support wide-area communication. ICS now exchange insecure traffic on an inter-domain level, putting at risk not only common critical infrastructure but also the internet ecosystem (e.g., by DRDoS attacks). In this paper, we measure and analyze inter-domain ICS traffic at two central internet vantage points, an IXP and an ISP. These traffic observations are correlated with data from honeypots and internet-wide scans to separate industrial from non-industrial ICS traffic. We uncover mainly unprotected inter-domain ICS traffic and provide an in-depth view on internet-wide ICS communication. Our results can be used (i) to create precise filters for potentially harmful non-industrial ICS traffic and (ii) to detect ICS sending unprotected inter-domain ICS traffic, being vulnerable to eavesdropping and traffic manipulation attacks. Additionally, we survey recent security extensions of ICS protocols, of which we find very little deployment. We estimate an upper bound of the deployment status for ICS security protocols in the internet core.

Finite State Machine Parsing for internet protocols: Faster Than You Think

Finite State Machine Parsing for Internet Protocols: Faster ...

35th IEEE-Computer-Society Workshop on Security and Privacy (SP)

A parser's job is to take unstructured, opaque data and convert it to a structured, semantically meaningful format. As such, parsers often operate at the border between untrusted data sources (e.g., the internet) and the soft, chewy center of computer systems, where performance and security are paramount. A firewall, for instance, is precisely a trust-creating parser for internet protocols, permitting valid packets to pass through and dropping or actively rejecting malformed packets. Despite the prevalence of finite state machines (FSMs) in both protocol specifications and protocol implementations, they have gained little traction in parser code for such protocols. Typical reasons for avoiding the FSM computation model claim poor performance, poor scalability, poor expressibility, and difficult or time-consuming programming. In this research report, we present our motivations for and designs of finite state machines to parse a variety of existing internet protocols, both binary and ASCII. Our hand-written parsers explicitly optimize around L1 cache hit latency, branch misprediction penalty, and program-wide memory overhead to achieve aggressive performance and scalability targets. Our work demonstrates that such parsers are, contrary to popular belief, sufficiently expressive for meaningful protocols, sufficiently performant for high-throughput applications, and sufficiently simple to construct and maintain. We hope that, in light of other research demonstrating the security benefits of such parsers over more complex, Turing-complete codes, our work serves as evidence that certain "practical" reasons for avoiding FSM-based parsers are invalid.

ACP plus An Age Control Protocol for the internet

引用

IEEE-ACM TRANSACTIONS ON NETWORKING 2024年第4期32卷 3253-3268页

作者： Shreedhar, Tanya Kaul, Sanjit K. Yates, Roy D. Univ Edinburgh Edinburgh EH8 9YL Scotland Delhi IIIT Delhi Indraprastha Inst Informat Technol New Delhi 110020 India Rutgers State Univ Dept Elect & Comp Engn ECE Wireless Informat Networks Lab WINLAB Piscataway NJ 08854 USA

We present the age control protocol ACP + , a transport layer protocol that regulates the rate at which update packets carrying information from a source are sent over the internet to a monitor. The source would like to minimize the average age of information at the monitor. Extensive experimentation helps shed light on age control over the current internet and its implications for sources sending updates over a shared wireless access to monitors in the cloud. Surprisingly, age minimizing rates over fast internet paths are about 0.5 Mbps, which is a small fraction, for example, of link rates supported by WiFi wireless access technology. We also show that congestion control algorithms employed by the Transmission Control Protocol (TCP), including hybrid approaches that achieve higher throughputs at lower delays than traditional loss-based congestion control, are unsuitable for age control.

Deep-Learning-Based Uncertainty-Estimation Approach for Unknown Traffic Identification

IEEE Transactions on Artificial Intelligence

IEEE Transactions on Artificial Intelligence 2025年第3期6卷 533-548页

Real open network environments include the traffic generated by known applications or protocols, which have been previously identified and labeled, and unknown network traffic that cannot be identified based on existing knowledge. Accurately identifying unknown traffic is critical to network management and security, not only to help managers allocate bandwidth appropriately for all types of applications and ensure quality of service but also to prevent security breaches that may result from unknown applications or protocols. Notably, the unknown network traffic has been increasing with the emergence of new applications or protocols, which further increases the difficulty in identifying them. Existing unknown traffic classification methods based on Softmax output confidence values cause bias in the prediction probability due to overconfidence of the model during the training process, thus decreasing the identification accuracy. Thus, for unknown traffic identification, this study proposes a deep-learning-based uncertainty-estimation (EUE) approach. EUE introduces the theory of evidence to the task of identifying unknown traffic by inferring traffic uncertainty directly from traffic evidence without the need for a Softmax layer, thus avoiding overconfidence in the model. Thus, the EUE can accurately identify unknown traffic while classifying known traffic at the application level. We construct two experimental scenarios simulating the real network environments with different proportions of unknown traffic to evaluate EUE. The experimental results show that the proposed approach EUE exhibits excellent classification accuracy. © 2024 IEEE. All rights reserved.

Security Vulnerability Protection in the Communication Network: A Legal Perspective

引用

International Journal of Network Security 2025年第3期27卷 497-503页

作者： Li, Jingwei Qi, Peng College of Law Xi’an Jiaotong University No. 28 Xianning West Road Shaanxi Xi’an710049 China

This paper introduces security protection for the communication network from a legal perspective. The communication protocols of the communication network and their protocol reports were considered as texts. An intelligent algorithm was used to identify vulnerabilities in the texts. The texts were vectorized by word-to-vector (Word2vec) in the algorithm. The algorithm calculated the mutual information value of the code text words by utilizing term frequency-inverse document frequency (TF-IDF) values and combined it with the text vector. The convolutional structure of a convolutional neural network (CNN) was used to extract features automatically, and vulnerabilities were identified using the long short-term memory (LSTM) algorithm. Simulation experiments were performed to compare the proposed method with the support vector machine (SVM) and traditional LSTM algorithms. The results indicated that when the number of nodes in the hidden layer of LSTM was 256 and the sigmoid activation function was utilized, the vulnerability identification performance of the proposed algorithm was the most effective. Compared to the SVM and traditional LSTM algorithms, this algorithm showed superior vulnerability identification performance for vulnerabilities in communication protocols. © (2025), (Femto Technique Co.).

Distributing and Synchronizing Signals Between the Worlds of SDI and IP

引用

SMPTE Motion Imaging Journal 2023年第2期132卷 51-56页

Moving signals between the worlds of serial digital interface (SDI) and internet Protocol (IP) is not exactly rocket science, but synchronizing these signals may prove to be a challenge. It is these cases that we will discuss in this article and these challenges to which we seek to identify and present a viable and cost-effective solution. We will consider a recent Riedel project with a major U.S. broadcaster. Following the decision to move its operations to ST 2110, this broadcast network experienced synchronization problems between its IP-based flagship station and more than 200 affiliate stations throughout North America relying on SDI. The fact that the remote feed needed to be compressed posed yet another challenge, as it required the decompressed signal to be decoded to ST 2110 before it could be converted to SDI. The Riedel team managed to solve the synchronization issue with a single, powerful device smaller than the size of your thumb: A software-defined processing small form-factor pluggable (SFP) device that enabled the conversion of UHD-1 and ST 2110 signals for bidirectional distribution between the headquarters and the affiliate stations while generating a Precision Time Protocol (PTP) Grand Master clock from the affiliate's synchronized signal. This greatly reduced both system complexity and the cost of replacing the entire affiliate synchronization system. After a general description of the specific use-case setup, we will present an overview of the various possible solutions and weigh the pros and cons before focusing on the most viable solution. After short explanations of the demarcation switch configuration and the Epoch reference generation at the affiliate sites, we conclude with an outlook on other potential use cases. © 2002 Society of Motion Picture and Television Engineers, Inc.
