The implementation of communication protocols in the current Internet architecture is tightly-coupled which hinders the evolution of the Internet. This article describes how the principles of Service Oriented Architecture (SOA) can be employed to develop a flexible network architecture. The prototype of the concept has been developed and demonstrated in the EuroView 2012 workshop. We showed that the SOA paradigm can be applied to networks by utilizing the concepts of self-contained building blocks, dynamic protocol graphs (PGs) and functional composition (FC) methods. We demonstrated that both short-term flexibility (i.e., networks are adapted based on application requirements) and long-term flexibility (i.e., networks can be evolved) can be achieved by using the architecture.

“…One approach is to empower the message with the intelligence to decide the path through the stack and the functions necessary in relation to the requirements of the packet [22] [23]. Another approach is to group the functions specific to an application at all layers [24] [25].…”

Abstract:The world of telecommunications continues to provide radical technologies. Offering the benefits of a superior television experience at reduced long-term costs, IPTV is the newest offering. Deployments, however, are slow to be rolled out; the hardware and software support necessary is not uniformly available. This paper examines the challenges in providing IPTV services and the limitations in developments to overcome these challenges. Subsequently, a proposal is made which attempts to help solve the challenge of fulfilling real-time multimedia transmissions through provisioning for differentiated services. Initial implementations in Opnet are documented, and the paper concludes with an outline of future work.

“…Perhaps unfortunate examples of this are the various "setsockopt," "fcntl," and "ioctl" calls for tweaking the behavior of network sockets in a small set of predefined ways. Many superior interfaces for asynchronous and copy-free data movement have been proposed Hutchinson and Peterson 1991;Krieger et al 1994;O'Malley and Peterson 1992;Pai et al 1999;Pasquale et al 1994; The Virtual Interface (VI) Architecture 1998; von Eicken et al 1995], though most systems are still not using them. An interface with great potential is NT's "sendfile" system call (now also available in linux and FreeBSD), under which several interesting performance enhancements could be implemented if the internal file system and TCP/IP implementations were reorganized.…”

Application-level networking is a promising software organization for improving performance and functionality for important network services. The Xok/ExOS exokernel system includes applicationlevel support for standard network services, while at the same time allowing application writers to specialize networking services. This paper describes how Xok /ExOS's kernel mechanisms and library operating system organization achieve this flexibility, and retrospectively shares our experiences and lessons learned (both positive and negative). It also describes how we used this flexibility to build and specialize three network data services: the Cheetah HTTP server, the webswamp Web benchmarking tool, and an application-level TCP forwarder. Overall measurements show large performance improvements relative to similar services built on conventional interfaces, in each case reaching the maximum possible end-to-end performance for the experimental platform. For example, Cheetah provides factor of 2-4 increases in throughput compared to highly tuned socket-based implementations and factor of 3-8 increases compared to conventional systems. Webswamp can offer loads that are two to eight times heavier. The TCP forwarder provides 50-300% higher throughput while also providing end-to-end TCP semantics that cannot be achieved with POSIX sockets. With more detailed measurements and profiling, these overall performance improvements are also broken down and attributed to the specific specializations described, providing server writers with insights into where to focus their optimization efforts.
