CMPSC 176B - NETWRK COMPUTING - Spring 2023
CS 176 B is an advanced undergraduate-level networking course. It builds up on principles, abstractions, and protocols we learned in CS 176 A. In the past decade, the area of computer networking has witnessed a massive transformation. Unlike the brittle and inflexible networks of the past, we now have programmable software-defined networks (SDN) fueling the exponential growth of content and computing services. This course introduces software-defined networking that allows a logically centralized software program to control the behavior of an entire network. Separating a network’s control logic from the underlying physical routers and switches that forward traffic allows network operators to write high-level control programs that specify the behavior of an entire network, in contrast to conventional networks, whereby network operators must codify functionality in terms of low-level device configuration. Logically centralized network control makes it possible for operators to specify more complex tasks that involve integrating many disjoint network functions (e.g., security, resource control, prioritization) into a single control framework, allowing network operators to create more sophisticated policies, and making network configurations easier to configure, manage, troubleshoot, and debug. In this course, we will learn how the network has transformed in recent years and how those transformations fuel the growth of content and computing service providers. More specifically, we will learn what software-defined networks (SDNs) are, what motivated their development, how researchers and practitioners built up on previous works to enable SDN, how it transformed networking, and what lies ahead. We will also learn how far we are from the communal goal of developing self-driving networks that run independently without requiring human intervention.
