About the Book
The book covers two topics - how SCTP works in theory and how to use it in Linux.
The best way to learn how SCTP works is to read and understand its specification - RFC 4960. However this document is not an easy read - the purpose of the document is to describe a full SCTP implementation and contains details which you usually don't need, unless you plan to write your own SCTP stack.
The role of the first five chapters of the book is to give you structured and easy to read explanation about how different parts of the protocol work. You will see how an SCTP association is established on network packet level, how data transfer works, how multi-homing is implemented and so on. Additionally each section contains references to specific sections from RFC 4960, which cover the topics in question. This approach will save you a lot of time reading the document.
The rest of the book focuses on SCTP from programmer point of view. You will learn how to write client-server applications in Linux. You will learn the difference between one-to-one and one-to-many style sockets and how to implement multi-homing. Each chapter contains working client and/or server implementation in C and line-by-line code review.
