Boost.Asio C++ Network Programming Cookbook by Dmytro Radchuk

By Dmytro Radchuk

Beginning with recipes demonstrating the execution of uncomplicated Boost.Asio operations, the e-book is going directly to supply ready-to-use implementations of patron and server functions from uncomplicated synchronous ones to strong multithreaded scalable recommendations. ultimately, you're awarded with complex issues equivalent to imposing a talk software, enforcing an HTTP consumer, and including SSL aid. all of the samples provided within the e-book are able to be utilized in genuine tasks simply out of the box.

As good as very good useful examples, the booklet additionally comprises prolonged supportive theoretical fabric on disbursed software layout and construction.

What you'll learn:
- increase your operating wisdom of 1 of the main respected C++ networking libraries―Boost.Asio
- get yourself up to speed with the fundamentals of TCP and UDP protocols
- Create scalable and highly-efficient consumer and server applications
- comprehend the idea in the back of improvement of allotted applications
- elevate the safety of your allotted functions through including SSL support
- enforce a HTTP purchaser easily
- Use iostreams, scatter-gather buffers, and timers

Introduction to Networks Companion Guide

Advent to Networks better half consultant is the reputable supplemental textbook for the creation to Networks path within the Cisco® Networking Academy® CCNA® Routing and Switching curriculum.

The path introduces the structure, constitution, services, elements, and types of the net and computing device networks. the rules of IP addressing and basics of Ethernet techniques, media, and operations are brought to supply a starting place for the curriculum. by way of the top of the direction, it is possible for you to to construct basic LANs, practice uncomplicated configurations for routers and switches, and enforce IP addressing schemes.

The spouse advisor is designed as a conveyable table connection with use every time, anyplace to enhance the cloth from the path and arrange a while.

Ad Hoc & Sensor Networks: Theory And Applications

This booklet introduces a brand new explanatory cross-layer version particularly designed to appreciate all facets of advert hoc and sensor networking, from layout via functionality concerns to program necessities. destiny instructions, demanding situations and power simulation tasks also are mentioned. the subjects integrated signify a good portion of what's occurring in academia and undefined.

Personal Wireless Communications: Pwc 05 - Proceedings of the 10th Ifip Conference

The tenth IFIP foreign convention on own instant Communications covers a large spectrum: instant sensors, signalization, site visitors and QoA in instant networks, Ad-Hoc, IEEE 802. eleven, mobile and cellular networks. This quantity bargains a wide variety of suggestions to key difficulties in instant networking and explores demanding avenues for business examine and improvement.

Example text

Asio output // operations. Asios socket's method that performs an input operation such as asio::ip::tcp::socket::receive() or the asio::read()free function: 1. Allocate a buffer. The size of the buffer must be big enough to fit the block of data to be received. Asio. 2. Represent the buffer using an object that satisfies the MutableBufferSequence concept's requirements. 3. Asio input methods and functions. Let's say we want to receive a block of data from the server. To do this, we first need to prepare a buffer where the data will be stored.

The second type is an asynchronous operation. Asio library when the operation is finished. These types of I/O operations provide great flexibility, but may significantly complicate the code. The initiation of the operation is simple and doesn't block the thread of execution, which allows us to use the thread to run other tasks, while the asynchronous operation is being run in the background. Asio library is implemented as a framework, which exploits an inversion of control approach. After one or more asynchronous operations are initiated, the application hands over one of its threads of execution to the library, and the latter uses this thread to run the event loop and invoke the callbacks provided by the application to notify it about the completion of the previously initiated asynchronous operation.

Std::cout << "Failed to open the socket! value() << ". value(); } return 0; } 16 Chapter 1 See also ff The Creating a passive socket recipe, as its name suggests, provides discussion of passive sockets and demonstrates their use ff The Connecting a socket recipe explains one of the uses of active sockets, namely connecting to the remote application Creating a passive socket A passive socket or acceptor socket is a type of socket that is used to wait for connection establishment requests from remote applications that communicate over the TCP protocol.
