Everyone enjoys the smartphone revolution - users, developers, network operators, device vendors and network equipment vendors such as Ericsson. However, there are challenges since the network systems have not been optimised for smartphones from start. Until recently, the key optimisation objectives for mobile broadband networks have been peakrate and throughput, which are still important properties. The advent of mass-usage of smartphones, and the related traffic, has shown that also other properties of the 3G radio and networks are important. In particular, the high frequency of data activities, sometimes with moderate volumes of data transferred, has lead to both a high battery drain, and increased the signaling load in the system, due to the transitions between the standardised states of the 3G radio.
Distributed Shared Memory on Ericsson LabsEricsson Labs

The document discusses principles of network applications and the application layer. It covers transport services available to applications like reliable data transfer, throughput, timing and security. It also discusses application architecture like client-server and peer-to-peer models. Application layer protocols define message types, syntax, semantics and process communication rules. The Internet provides TCP for reliable connection-oriented transfer and UDP for unreliable connectionless transfer. Processes communicate by exchanging messages, with clients initiating sessions and servers waiting to be contacted.
Tim Berners-Lee wrote the first proposal for the World Wide Web in 1989 and formalized it with Robert Cailliau in 1990, outlining key concepts like hypertext documents and browsers. By the end of 1990, Berners-Lee had the first web server and browser running at CERN. The main job of a web server is to store, process, and deliver web pages to users through HTTP and other protocols in response to client requests. When a client makes a request, the server finds and retrieves the requested file or returns an error message.
The document discusses the World Wide Web (WWW) and Hypertext Transfer Protocol (HTTP). It describes the basic architecture of the WWW including clients, servers, web pages, and URLs. It explains that web pages can be static, dynamic, or active. The document then discusses HTTP in more detail, including how HTTP requests and responses are structured, how persistent connections work in HTTP 1.1, and how caching can improve performance.
The document provides an introduction to web application development basics. It discusses how the world wide web is based on clients (web browsers) and servers. Web browsers allow users to access and navigate the internet, while web servers watch for and respond to requests from browsers by finding and sending back requested documents. The document also describes how browsers communicate with servers using protocols like HTTP and how dynamic web pages are generated through CGI scripts or server-side scripting languages.
Web services allow applications to communicate over the web through XML. Windows Communication Foundation (WCF) and Web API both enable building web services, but WCF focuses on interoperability across protocols while Web API is ideal for building RESTful services compatible with browsers and devices. WCF supports features like transactions and reliability but requires defining bindings, while Web API is simpler and uses HTTP verbs for CRUD actions. The choice depends on requirements for interoperability versus a RESTful approach.
