چکیده

How to allow fast network processing unit (NPU) performance testing in supporting fast data path functions in a router is a challenging issue. It is more so in a router design phase when there are a vast number of design choices to be tested and the microcode for the fast data path functions is yet to be developed. In this paper, based on the instruction-andlatency-budget-based NPU analysis methodology, we put forward an approach to allow NPU throughput upper bounds at arbitrary number of threads to be estimated quickly (in a fraction of a second on a Pentium II PC). These performance bounds allow the performance of fast data path functions to NPU configuration mapping to be quickly tested solely based on the worst-case code path derivable from the pseudo code of the fast data path functions. Case studies based on the code samples available in the Intel IXP 1200 and 2400 Developer Workbenches are performed. The performance bounds are found to be within 17% of the cycle-accurate simulation results.

A Fast Voltage Collapse Detection and Prevention Based on Wide Area Monitoring and Control

Voltage stability is one of the most important factors in maintaining reliable operation of power systems. When a disturbance occurs in the power system, it usually causes instabilities and sometimes leads to voltage collapse (VC). To avoid such problems, a novel approach called Vector Analysis (VA) is proposed that exploits a new instability detection index to provide wide area voltage stabili...

DisTriB: Distributed Trust Management Model Based on Gossip Learning and Bayesian Networks in Collaborative Computing Systems

The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...
