Any intelligent system, interacting with humans and acting in the real world, will be composed of many parts, each performing disparate and specialized tasks with wildly differing requirements. We have implemented a network abstraction layer, called NetP, that allows processes to communicate by sending structured data via non-blocking broadcasts to named channels. Any process can subscribe to a...

ion-Based Performance Analysis of NoCs Daniel E. Holcomb UC Berkeley [email protected] Bryan A. Brady UC Berkeley [email protected] Sanjit A. Seshia UC Berkeley [email protected] ABSTRACT We present an approach to formally analyze quality-of-service (QoS) properties of network-on-chip (NoC) designs. To tackle industrialscale designs, we adopt an abstraction-based approach...

Decoupling infrastructure management from service management can lead to innovation, new business models, and a reduction in the complexity of running services. It is happening in the world of computing, and is poised to happen in networking. While many have considered this in the context of network virtualization, they all focus on one model – overlaying a virtual network of multiple virtual r...

System of systems engineering seeks to analyze, design and deploy collections that together can flexibly address an array complex tasks. In the Complex Adaptive Composition Design Environment program, we developed "network operads" as a tool for designing tasking systems, applied them domains including maritime search rescue. The network operad formalism offers new ways handle changing levels a...

The file is a well-understood and very simple abstraction, which has been successfully used in both centralized and distributed systems. However, files are not expressive enough to capture high-level data semantics and relationships, including sharing and data dependencies. How many times has your operating system translated a JPEG figure into postscript, automatically when needed? How do files...

Routing is a challenging problem for wireless ad hoc networks, especially when the nodes are mobile and spread so widely that in most cases multiple hops are needed to route a message from one node to another. In fact, it is known that any online routing protocol has a poor performance in the worst case, in a sense that there is a distribution of nodes resulting in bad routing paths for that pr...

Datacenter operators and internet content providers require optical network programmability to efficiently interconnect distributed datacenters. This paper describes the requirements, applications and use cases for optical network programmability. Based on application scenarios, open northbound APIs with different levels of control and abstraction to address different network operator requireme...
