CHAPTER 2
A Simple Interconnection
Network
In this chapter, we examine the architecture and design of a simple interconnection
network to provide a global view. We will examine the simplest possible network:
a butterfly network with dropping flow control. Although the resulting network is
costly, it emphasizes many of the key aspects of interconnection network design. In
later chapters, we will learn how to produce more efficient and practical networks.
2.1 Network Specifications and Constraints
Like all engineering design problems,network design starts with a set of specifications
that describe what we wish to build and a set of constraints that limit the ...
