• Table of Contents C++ Network Programming, Volume 2: Systematic Reuse with ACE and Frameworks By Douglas C Schmidt, Stephen D Huston Publisher : Addison Wesley Pub Date : October 29, 2002 ISBN : 0-201-79525-6 Pages : 384 Do you need to develop flexible software that can be customized quickly? Do you need to add the power and efficiency of frameworks to your software? The ADAPTIVE Communication Environment (ACE) is an open-source toolkit for building high-performance networked applications and next-generation middleware ACE's power and flexibility arise from object-oriented frameworks, used to achieve the systematic reuse of networked application software ACE frameworks handle common network programming tasks and can be customized using C++ language features to produce complete distributed applications C++ Network Programming, Volume 2, focuses on ACE frameworks, providing thorough coverage of the concepts, patterns, and usage rules that form their structure This book is a practical guide to designing object-oriented frameworks and shows developers how to apply frameworks to concurrent networked applications C++ Networking, Volume 1, introduced ACE and the wrapper facades, which are basic network computing ingredients Volume 2 explains how frameworks build on wrapper facades to provide higher-level communication services Written by two experts in the ACE community, this book contains: An overview of ACE frameworks Design dimensions for networked services Descriptions of the key capabilities of the most important ACE frameworks Numerous C++ code examples that demonstrate how to use ACE frameworks C++ Network Programming, Volume 2, teaches how to use frameworks to write networked applications quickly, reducing development effort and overhead It will be an invaluable asset to any C++ developer working on networked applications • Table of Contents C++ Network Programming, Volume 2: Systematic Reuse with ACE

application's work, such as receive and demarshal network input, or process requests A task is executed using one or more threads Template A C++ programming language feature that enables classes and functions to be parameterized by various types, constants, or pointers to functions A template is often called a generic or parameterized type Thread An independent sequence of instructions that executes within an address space that can be shared with other threads Each thread has its own run-time stack and registers, which enables it to perform synchronous I/O without blocking other threads that are executing concurrently Compared to processes, threads maintain minimal state information, require relatively little overhead to spawn, synchronize and schedule, and usually communicate with other threads via objects in their process's memory space, rather than shared memory Thread-per-Connection A concurrency model that associates a separate thread with each network connection This model handles each client that connects with a server in a separate thread for the duration of the connection It is useful for servers that must support long-duration sessions with multiple clients It is not useful for clients, such as HTTP 1.0 Web browsers, that associate a single request with each connection, which is effectively a thread-per-request model Thread-per-Request A concurrency model that spawns a new thread for each request This model is useful for servers that must handle long-duration request events from multiple clients, such as database queries It is less useful for short-duration requests, due to the overhead of creating a new thread for each request It can also consume a large number of operating system resources if many clients send requests simultaneously Thread Pool A concurrency model that allocates a set of threads that can perform requests simultaneously This model is a variant of thread-perrequest that amortizes thread creation costs by prespawning a pool of threads It is useful for servers that want to limit the number of operating system resources they consume Client requests can be executed concurrently until the number of simultaneous requests exceeds the number of threads in the pool At this point, additional requests must be queued until a thread becomes available Thread Safe Safe from any undesired side effects (race conditions, data collisions, etc.) caused by multiple threads executing the same section of code concurrently Thread-Safe Interface Pattern A design pattern that minimizes locking overhead and ensures that intracomponent method calls do not incur "self-deadlock" by trying to reacquire a lock that is held by the component already Thread-Specific Storage (TSS) Pattern A design pattern that allows multiple threads to use one "logically global" access point to retrieve an object that is local to a thread, without incurring locking overhead on each object access Traits A type that conveys information used by another class or algorithm to determine policies or implementation details at compile time Trojan Horse A harmful piece of software that is hidden in a seemingly harmless software module such as a trusted run-time library Type Safe A property enforced by a programming language's type system to ensure that only valid operations can be invoked upon instances of types Unicode A standard for character representation that includes characters for most written languages as well as representations for punctuation, mathematical notations, and other symbols Weakly Typed A datum whose declared data type does not fully reflect its intended or purported use Wrapper Facade One or more classes that encapsulate functions and data within a type safe object-oriented interface Bibliography [Ale01] Andrei
