“…What distinguishes NETIBIS from other projects is that it is completely in user space, that it is Java-specific and (Grid) application oriented, and focuses equally on efficiency and runtime configurability. Recent research on software routers, active networks and packet filtering also proposes modular, dynamic configuration of network stacks [4,5,11]. These stacks may run on network hardware, in the kernel and partly in user space.…”

Grids are more heterogeneous and dynamic than traditional parallel or distributed systems, both in terms of processors and of interconnects. A grid communication system must handle many issues: first, it must run on networks that are not yet determined when the application is launched, including user-space interconnects; second, it must transparently run on different networks at the same time; third, it should yield performance close to that of specialized communication systems. In this paper, we present NETIBIS, a new Java communication system that provides a uniform interface for any underlying intercluster or intracluster network. NETIBIS solves the heterogeneity issues posed by Grid computing by dynamically constructing network protocol stacks out of drivers, self-contained building blocks for flexible configuration, with limited functionality per driver. We describe the design and implementation of the major NETIBIS drivers for serialization, multicast, reliability, and various underlying networks. We also describe various optimizations for performance, like layer collapsing for the GM driver. We evaluate the performance of NETIBIS on several platforms, including a European grid.

“…In SCAMPI we have implemented an interface between the OKE and a Click configuration, that allows one to extend a Click configuration with OKE modules at runtime. In fact, using an implementation that combines OKE with a Click-like software model, known as Corral, we are able to maintain a consistent software model throughout the middleware [6].…”

Abstract. Effective network monitoring is vital for the growing number of control and management applications typically found in present-day networks. Increasing link speeds and the diversity of monitoring applications' needs have exposed severe limitations of existing monitoring techniques. As a response, the EU IST SCAMPI project designs and implements a scalable and programmable architecture for monitoring multi-gigabit networks. The SCAMPI architecture has an expressive programming interface, uses intelligent hardware, provides user policy management and resource control, and achieves scalability through parallelism. This paper addresses the problems with current high-speed network monitoring and presents the system architecture and components of the SCAMPI platform.

“…For example, [21] describes reflective support for checking the integrity of coordination/ control code being downloaded into an execution environment, and [40] further supports some degree of dynamic reconfiguration of downloaded control code. More recently, [46] supports reconfiguration through dynamic linking, but not in the context of a principled reflective component model. On the other hand, [47] provides a reflective component model but focuses on a flexible deployment architecture rather than on fine-grained reconfiguration.…”

While there has already been significant research in support of openness and programmability in networks, this paper argues that there remains a need for generic support for the integrated development, deployment and management of programmable networking software. We further argue that this support should explicitly address the management of run-time reconfiguration of systems, and should be independent of any particular programming paradigm (e.g. active networking or open signaling), programming language, or hardware/ operating system platform. In line with these aims, we outline an approach to the structuring of programmable networking software in terms of a ubiquitously applied software component model that can accommodate all levels of a programmable networking system from low-level system support, to in-band packet handling, to active networking execution environments to signaling and coordination.
