Network Algorithmics: An Interdisciplinary Approach to Designing Fast Networked Devices

Autor George Varghese
en Limba Engleză Hardback – 31 dec 2004

Prin parcurgerea lucrării Network Algorithmics, cititorul va reuși să implementeze dispozitive de rețea de mare viteză, optimizând algoritmi esențiali pentru rutere, firewall-uri și servere performante. Ne-a atras atenția abordarea interdisciplinară a autorului George Varghese, care nu se limitează doar la teorie, ci oferă o metodologie coerentă pentru eliminarea blocajelor de performanță ce apar inevitabil la intersecția dintre software și hardware.

Observăm că textul este construit pe o structură riguroasă, debutând cu identificarea obstacolelor la nivel de OS și hardware, urmată de prezentarea a 15 principii de implementare. Suntem de părere că valoarea practică a cărții rezidă în capitolele dedicate funcțiilor specifice: de la mecanisme de „Exact Match Lookups” și „Packet Classification”, până la gestionarea eficientă a timerelor și a procesării de protocol. Pe linia practică a volumului High-Speed Networking de James P G Sterbenz, dar cu un focus mult mai pronunțat pe algoritmii de optimizare a dispozitivelor (Network Algorithmics), această lucrare devine un instrument de lucru pentru inginerii de la companii precum Cisco sau Intel.

Fiecare secțiune este susținută de aproximativ 200 de ilustrații care clarifică fluxurile de date și deciziile de arhitectură. Spre deosebire de alte titluri care tratează rețelele din perspectivă pur matematică, Network Algorithmics este un ghid de inginerie aplicată, oferind soluții concrete pentru probleme de latență și throughput în sisteme distribuite complexe.

Public țintă

Network protocol implementers, from server vendors (i.e., Sun, IBM, Microsoft) to router vendors (i.e., Cisco, Juniper, PMC Sierra, Redback, Alcatel, Intel Networks). Also appeals to designers of efficient Intrusion Detection Systems (IDS) and firewalls which includes implementers at companies such as Cisco, ISS, Raptor, Symantec, Checkpoint, Network Associates, as well as companies and startups in security, storage and networking.

De ce să citești această carte

Recomandăm această carte inginerilor și dezvoltatorilor care proiectează hardware și software de rețea. Cititorul câștigă o înțelegere profundă a celor 15 principii care guvernează viteza rețelelor moderne, învățând cum să elimine blocajele din protocoale și sisteme de operare. Este resursa ideală pentru cei care vor să construiască rutere, sisteme IDS sau servere web capabile să gestioneze volume masive de date fără pierderi de performanță.


Descriere scurtă

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.

  • Addresses the bottlenecks found in all kinds of network devices, (data copying, control transfer, demultiplexing, timers, and more) and offers ways to break them
  • Presents techniques suitable specifically for endnodes, including Web servers
  • Presents techniques suitable specifically for interconnect devices, including routers, bridges, and gateways
  • Written as a practical guide for implementers but full of valuable insights for students, teachers, and researchers
  • Includes end-of-chapter summaries and exercises

Recenzii

"George Varghese has had a remarkable impact on the real world of networking with his algorithmic innovations over many years. The networking research and development community is fortunate that he has now distilled his knowledge in this very readable, insightful, and much-needed book." --Bruce Davie, Cisco Fellow, Cisco Systems
"This book nicely describes implementation tricks for building fast networking stacks, particularly in routers. This is a much needed book, I don't know of any other that covers this sort of implementation advice. George Varghese has invented several techniques to help speed up the Internet and in his book he provides interesting insight into this, and much more." --Radia Perlman, Distinguished Engineer, Sun Microsystems
