Web Browser as an Application Platform

Abstract: For better or worse, the web browser has become a widely used target platform for software applications. Desktop-style applications such as word processors, spreadsheets, calendars, games and instant messaging systems that were earlier written for specific operating systems, CPU architectures or devices are now written for the World Wide Web, to be used from a web browser. In this paper we summarize our experiences in using the web browser as a target platform for real applications. As a concrete example, we use the Sun? Labs Lively Kernel, a system that implements an exceptionally interactive web programming environment running in a web browser without any plug-in components. Based on this work, we analyze the limitations, challenges and opportunities related to the web browser as an application platform.

Sensitivity-driven co-synthesis of distributed embedded systems

Abstract: Describes a new, sensitivity-driven algorithm for the co-synthesis of real-time distributed embedded systems. Many embedded computing systems are distributed systems: communicating periodic processes executing on several CPUs/ASICs connected by communication links. We use performance estimates to compute a local sensitivity of the design to process allocation. We propose a priority prediction method to schedule processes. Based on these techniques, we develop a gradient-search algorithm which co-synthesizes heterogeneous distributed systems of arbitrary topology and the associated application software architecture. Experimental results show that our algorithm can find good implementation architectures in small amounts of CPU time.

Engineering the cloud from software modules

Abstract: Cloud computing faces many of the challenges and difficulties of distributed and parallel software. While the service interface hides the actual application from the remote user, the application developer still needs to come to terms with distributed software that needs to run on dynamic clusters and operate under a wide range of configurations. In this paper, we outline our vision of a model and runtime platform for the development, deployment, and management of software applications on the cloud. Our basic idea is to turn the notion of software module into a first class entity used for management and distribution that can be autonomously managed by the underlying software fabric of the cloud. In the paper we present our model, outline an initial implementation, and describe a first application developed using the ideas presented in the paper.

Towards a cognitive routing engine for software defined networks

Abstract: In Software Defined Networks (SDN), intensive traffic monitoring is used to optimize the Quality-of-Service (QoS) of the network paths which are selected. Thus, we introduce the use of the Cognitive Packet Network (CPN) algorithm to SDN in order to optimize the search for new high-QoS paths. We install the CPN algorithm in the Cognitive Routing Engine (CRE), a new application software for SDN, and show that with limited monitoring overhead we are able to determine the near-optimal paths for given QoS metrics that may be proposed by the end users. Measurements that we have conducted on an experimental replica of the GEANT network that our approach uses close to 10 times less monitoring data than conventional SDN, but that we are able to approach the optimal paths within 2%.
