The Road to SDN: An Intellectual History of Programmable Networks (三)
2.2 Separating Control and Data Planes 单词学习 翻译 In the early 2000s, increasing traffic volumes and a greater emphasis on on network reliability, predictability, and performance led network operators to seek better approaches to certain network-management functions such as the control over the paths used to deliver traffic (a practice commonly known as traffic engineering). The means for performing traffic engineering using conventional routing protocols were primitive at best. Operators’ frustration with these approaches were recognized by a small, well-situated community of researchers who
