Dynamic classification in silicon-based forwarding engine environments

چکیده
-Current network devices enable connectivity between end systems with support for routing with a defined set of protocol software bundled with the hardware. These devices do not support user customization or the introduction of new software applications. Programmable network devices allow for the dynamic downloading of customized programs into network devices allowing for the introduction of new protocols and network services. The Oplet Runtime Environment (ORE) is a programmable network architecture built on a Gigabit Ethernet L3 Routing Switch to support downloadable services. Complementing the ORE, we introduce the JFWD API, a uniform, platform-independent portal through which application programmers control the forwarding engines of heterogeneous network nodes (e.g., switches and routers). Using the JFWD API, an ORE service has been implemented to classify and dynamically adjust packet handling on silicon-based network devices.

Evaluation of continuum damage at different temperatures for aluminum-silicon alloy of engine piston within low-cycle fatigue regime
In this article, the isothermal low-cycle fatigue continuum damage in the engine piston aluminum alloy has been evaluated at different temperatures. For this objective, experimental data of low-cycle fatigue tests on standard specimens were used at 280, 350 and 425°C. Based on the continuum damage mechanics method, the fatigue damage was calculated during cyclic loading. Obtained results, inclu...
متن کاملAn Investigation on the Effects of Gas Pressure Drop in Heat Exchangers on Dynamics of a Free Piston Stirling Engine
This paper is devoted to study the effects of pressure drop in heat exchangers on the dynamics of a free piston Stirling engine. First, the dynamic equations governing the pistons as well as the gas pressure equations for hot and cold spaces of the engine are extracted. Then, by substituting the obtained pressure equations into the dynamic relationships the final nonlinear dynamic equations gov...
متن کاملAssessment Methodology for Anomaly-Based Intrusion Detection in Cloud Computing
Cloud computing has become an attractive target for attackers as the mainstream technologies in the cloud, such as the virtualization and multitenancy, permit multiple users to utilize the same physical resource, thereby posing the so-called problem of internal facing security. Moreover, the traditional network-based intrusion detection systems (IDSs) are ineffective to be deployed in the cloud...
متن کاملAnalytical Approach for Vibration Analysis of a Microsensor with Two layers of Silicon and Piezoelectric based on MCST
The vibration analysis is an important step in the design and optimization of microsensors. In most of the cases, COMSOL software is employed to consider the size-dependency on the dynamic behavior in the MEMS sensors. In this paper, the Modified Couple Stress Theory (MCST) is used to capture the size effect on dynamic behavior in a microsensor with two layers of the silicon and piezoelectric. ...
متن کاملNovel Hardware Implementation for Fast Address Lookups
The major bottleneck in the performance of routers is the address lookup for determining the next hop address. The problem of determining the next hop is made more complicated by the fact that routers store variable length prefixes in the forwarding tables. This paper describes a new hardware algorithm that gives a fast and efficient solution for address lookups. As implemented in the forwardin...
