in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...

Predictive algorithms play a crucial role in systems management by alerting the user to potential failures. We report on three case studies dealing with the prediction of failures in computer systems: (1) long-term prediction of performance variables (e.g., disk utilization), (2) short-term prediction of abnormal behavior (e.g., threshold violations), and (3) short-term prediction of system eve...

Prediction of network failures at the router level has been achieved using an Intelligent Agent. The intelligent agent gathers relevant MIB data from the router and provides temporally and spatially correlated predictive alarms. The time correlated abnormal changes in the individual MIB variables are spatially correlated using a novel combining scheme. The agent was implemented on a real networ...

background:  wi-fi allows electronic devices such as laptops to exchange data or connect to a network resource. the main goal of this study was to assess the bioeffects of short term exposure to 2.4 ghz microwave radiation emitted from a common wi-fi router on sperm quality. materials and methods: male wistar rats were divided into 7 groups; i, sham exposed 4 h/day for 7days at 30 cm from the r...

We are analyzing BGP beacons which are announced and withdrawn, usually within two hour intervals. These announcements and more particularly the withdraws have an effect on neighboring prefixes and down the line to their neighbors as well. We are conducting analysis on the number of updates that are propagated as a result of these events. We then look at the number of updates which could have b...

Perkembangan teknologi jaringan dari waktu ke semakin pesat, oleh karena itu diperlukan akses yang aman atau secure. Dengan banyaknya jaringan, maka akan banyak pula peluang terjadinya kejahatan di dalam tersebut. Penelitian ini menggunakan metode penetration testing bertujuan untuk menganalisis celah keamanan pada login router Mikrotik SMKN 2 Sumbawa. Dalam melakukan trial attack, penelitian B...

In this paper, we propose a fault management with fast rerouting restoration scheme in MPLS network. The proposed scheme finds out the root cause of the occurred fault, and provides differentiated service with guaranteed QoS (Quality of Service) according to the differentiated backup path options. It can provide various backup path options, such as 1:1, 1:N or M:N fast-reroute by NMS, and opera...
