Download or read book Building Efficient Packet Classification Systems Through Software centric Approaches written by and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building high-performance and extensible networking devices is one of the hottest topics in computer networking. However, several factors make this task challenging. First, the performance of software routers is limited, although they are easily extensible and programmable. Second, the latest commercial routers are the standard for high performance but they rely on specialized hardware and software that is difficult to extend. This thesis focuses on designing and implementing practical and extensible software-centric solutions for building high-performance routers. We improved the performance of packet classification systems in multiple ways, including speed, power consumption and storage requirements. Our work has had a broad impact on various packet classification systems. 1) Our software router work exploited the parallelism in state-of-art multi-core desktop platforms, and it achieved a packet classification speed of more than 10 Gbps on a single 8-core Intel Xeon processor desktop platform. 2) We introduced the concept of the pre-classifier, which reduced the dimensionality of the multi-dimensional packet classification. We then applied the pre-classifier to a TCAM-based power-efficient packet classification system and a software-based memory-efficient packet classification system. 3) In light of new hardware features in TCAMs, including parallel search and partial address support, our TCAM design, which includes a pre-classifier, reduced power consumption by more than 80% when used for multi-dimensional packet classification. 4) We observed that RAM-based algorithmic solutions for multi-dimensional packet classification either require a large memory size to load the rules, or they require a large number of memory accesses for a packet classification. Therefore, we proposed a memory-efficient packet classification system that includes a pre-classifier and achieves a large memory size reduction at lower cost of memory accesses. For future work, we plan to apply our packet classification techniques to systems with limited resources, such as systems with limited TCAM size. We also plan to apply our techniques to the emerging problems in the domain of Software-Defined Networking.

Download or read book Telecommunication Networks written by Eugenio Iannone and published by CRC Press. This book was released on 2017-12-19 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many argue that telecommunications network infrastructure is the most impressive and important technology ever developed. Analyzing the telecom market’s constantly evolving trends, research directions, infrastructure, and vital needs, Telecommunication Networks responds with revolutionized engineering strategies to optimize network construction. Omnipresent in society, telecom networks integrate a wide range of technologies. These include quantum field theory for the study of optical amplifiers, software architectures for network control, abstract algebra required to design error correction codes, and network, thermal, and mechanical modeling for equipment platform design. Illustrating how and why network developers make technical decisions, this book takes a practical engineering approach to systematically assess the network as a whole—from transmission to switching. Emphasizing a uniform bibliography and description of standards, it explores existing technical developments and the potential for projected alternative architectural paths, based on current market indicators. The author characterizes new device and equipment advances not just as quality improvements, but as specific responses to particular technical market necessities. Analyzing design problems to identify potential links and commonalities between different parts of the system, the book addresses interdependence of these elements and their individual influence on network evolution. It also considers power consumption and real estate, which sometimes outweigh engineering performance data in determining a product’s success. To clarify the potential and limitations of each presented technology and system analysis, the book includes quantitative data inspired by real products and prototypes. Whenever possible, it applies mathematical modeling to present measured data, enabling the reader to apply demonstrated concepts in real-world situations. Covering everything from high-level architectural elements to more basic component physics, its focus is to solve a problem from different perspectives, and bridge descriptions of well-consolidated solutions with newer research trends.

Download or read book Network Algorithmics written by George Varghese and published by Morgan Kaufmann. This book was released on 2005 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: In designing a network device, you make dozens of decisions that affect the speed with which it will perform-sometimes for better, but sometimes for worse. Network Algorithmics provides a complete, coherent methodology for maximizing speed while meeting your other design goals. Author George Varghese begins by laying out the implementation bottlenecks that are most often encountered at four disparate levels of implementation: protocol, OS, hardware, and architecture. He then derives 15 solid principles-ranging from the commonly recognized to the groundbreaking-that are key to breaking these bottlenecks. The rest of the book is devoted to a systematic application of these principles to bottlenecks found specifically in endnodes, interconnect devices, and specialty functions such as security and measurement that can be located anywhere along the network. This immensely practical, clearly presented information will benefit anyone involved with network implementation, as well as students who have made this work their goal.

Download or read book Scalable Packet Processing for High speed Networks written by Yan Sun and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to design an efficient combined security gateway system, we first focus on how to design efficient three individual components, including routing table lookup, packet classification and deep packet inspection, and then propose an efficient combination approach to further reduce hardware consumption and increase overall throughput. Our approaches are mainly based on Ternary Content Addressable Memories (TCAMs) and the system can be easily implemented in a single FPGA. We focus on how to reduce redundancy in both individual components and integrated architecture to not only reduce the hardware consumption but also increase the overall throughput. The simulation results on both proposed individual components and integrated architecture show that we can achieve expected goals.

Download or read book Packet Classification for Core Routers written by Florin Baboescu and published by . This book was released on 2002 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A classifier consists of a set of rules for classifying packets based on header fields. Because core routers can have fairly large (e.g., 2000 rule) database and must use limited SRAM to meet OC-768 speeds, the best existing classification algorithms (RFC, HiCuts, ABV) are precluded because of the large amount of memory they need. Thus the general belief is that hardware solutions like CAMs are needed, despite the amount of board area and power they consume. In this paper, we provide an alternative to CAMs via an Extended Grid-of-Tries (EGT) algorithm whose worst-case speed scales well with database size while using a minimal amount of memory. Our evaluation is based on real databases used by Tier 1 ISPs, and synthetic databases. EGT is based on a observation that we found holds for all the Tier 1 databases we studied: regardless of database size, any packet matches only a small number of distinct source-destination prefix pairs. The code we wrote for EGT, RFC, HiCuts, and ABV is publicly available, providing the first publicly available code to encourage experimentation with classification algorithms.

This book was released on 2015-04-30 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relevance of the Internet has dramatically grown in the past decades. However, the enormous financial impact attracts many types of criminals. Setting up proper security mechanisms (e.g., Intrusion Detection Systems (IDS)) has therefore never been more important than today. To further compete with today's data transfer rates (10 to 100 Gbit/s), dedicated hardware accelerators have been proposed to offload compute intensive tasks from general purpose processors. As one key technology, reconfigurable hardware architectures, e.g., the Field Programmable Gate Array (FPGA), are of particular interest to this end. This work addresses the use of such FPGAs in the context of interactive communication applications, which goes beyond the regular packet level operations often seen in this area. To support rapid prototyping, a novel FPGA platform (NetStage) has been designed and developed, which provides a communication core for Internet communication and a flexible connection bus for attaching custom applications modules. A hardware honeypot (the MalCoBox) has been set up as a proof-of-concept application. Furthermore, to address the ongoing issue of hardware programming complexity, the domain-specific Malacoda language for abstractly formulating honeypot packet communication dialogs is presented and discussed. An associated compiler translates Malacoda into high-performance hardware modules for NetStage. Together, NetStage and Malacoda address some of the productivity deficiencies often recognized as major hindrances for the more widespread use of reconfigurable computing in communications applications. Finally, the NetStage platform has been evaluated in a real production environment.
