Traffic monitoring is the essential capability for large-scale enterprises, data centers, service providers, and network operators to ensure reliability, availability, fault assurance, and security of their underlying network resources. Currently, most monitoring solutions are standalone dedicated ones. Major drawbacks of these dedicated standalone appliances per-feature are high-cost, lack of flexibility,...
Cloud computing is great for scaling applications but the latency in a guest VM can be unpredictable due to resource contention between neighbors. For telephony applications, which are latency-sensitive, we propose a system to monitor telephony server latencies and adapt the server load based on the measured latencies. We implemented the system and evaluated it on an Amazon EC2 test bed. We show indirectly...
Application interference is prevalent in datacenters due to contention over shared hardware resources. Unfortunately, understanding interference in live datacenters is more difficult than in controlled environments or on simpler architectures. Most approaches to mitigating interference rely on data that cannot be collected efficiently in a production environment. This work exposes eight specific complexities...
In this knowledge and information society, the recent opening up of networks led to ever increasing threat to the security of computer systems. To solve this problem, TC(Trusted Computing) is being researched and developed. TCG(Trusted Computing Group) proposed a trustworthiness platform based on a semiconductor chip called TPM(Trusted Platform Module), designed to improve security and data reliability...
The TPB (trusted platform board) is an expansion of the TPM (trust platform module) chip for the elevation of the efficiency and usability of the TPM chip that has been developed from the TCG (trusted computing group) for the trust computing. In addition to the TPB function supporting environments for the high-standard trust within the hardware standard of the system, the present paper develops the...
