This work opens with an accessible introduction to computer networks, providing general definitions of commonly used terms in networking. This is followed by a detailed description of the OSI model, including the concepts of connection-oriented and connectionless communications. The text carefully elaborates the specific functions of each layer, along with what is expected of protocols operating at each layer. Next, the journey of a single packet, from source to destination, is described in detail. The final chapter is devoted to the TCP/IP model, beginning with a discussion of IP protocols and the supporting ARP, RARP and In ARP protocols. The work also discusses the TCP and UDP protocols operating at the transport layer and the application layer protocols HTTP, DNS, FTP, TFTP, SMTP, POP3 and Telnet. Important facts and definitions are highlighted in gray boxes found throughout the text.

This report, which considers the role of networking activities associated with the technical telecommunication links that bind libraries, services, and patrons together, begins with a historical review of libraries and automation-based systems over the last 19 years. The importance of the development and implementation of standards in interactive library activities for librarians using state or regional telecommunications networks is then discussed, including such factors as the need for increased functionality, performance reliability, consistent user assistance, access, and participation in governance. Also discussed are the activities of the various regional networks involved in the Linked Systems Project (lsp), including the development of standards for information transfer between systems via the telecommunications standard known as the Open Systems Interconnection (osi). The development of the Office of Library Program's leadership role in interlibrary cooperation, especially in the application of federal funding to inter- and intra-state cooperative programs for resource sharing, is also described. A concluding statement briefly discusses a number of issues currently involved in networking, and 10 recommendations are offered for the guidance of the Office of Library Programs in working toward the development of an underlying information infrastructure parallel with the telecommunications infrastructure being created by the National Science Foundation (nsf) and other federal agencies.

Network Programming with Go teaches you how to write clean, secure network software with the programming language designed to make it seem easy. Build simple, reliable, network software Combining the best parts of many other programming languages, Go is fast, scalable, and designed for high-performance networking and multiprocessing. In other words, it’s perfect for network programming. Network Programming with Go will help you leverage Go to write secure, readable, production-ready network code. In the early chapters, you’ll learn the basics of networking and traffic routing. Then you’ll put that knowledge to use as the book guides you through writing programs that communicate using TCP, UDP, and Unix sockets to ensure reliable data transmission. As you progress, you’ll explore higher-level network protocols like HTTP and HTTP/2 and build applications that securely interact with servers, clients, and APIs over a network using TLS. You'll also learn: Internet Protocol basics, such as the structure of IPv4 and IPv6, multicasting, DNS, and network address translation Methods of ensuring reliability in socket-level communications Ways to use handlers, middleware, and multiplexers to build capable HTTP applications with minimal code Tools for incorporating authentication and encryption into your applications using TLS Methods to serialize data for storage or transmission in Go-friendly formats like JSON, Gob, XML, and protocol buffers Ways of instrumenting your code to provide metrics about requests, errors, and more Approaches for setting up your application to run in the cloud (and reasons why you might want to) Network Programming with Go is all you’ll need to take advantage of Go’s built-in concurrency, rapid compiling, and rich standard library. Covers Go 1.15 (Backward compatible with Go 1.12 and higher)
