We present LAVEA, a system built for edge computing, which offloads computation tasks between clients and edge nodes, collaborates nearby edge nodes, to provide low-latency video analytics at places closer to the users. We have utilized an edge-first design to minimize the response time, and compared various task placement schemes tailed for inter-edge collaboration. Our results reveal that the client-edge...
Power loss from an uninterruptible power supply can account for 15 percent of a datacenter's energy. A rack-level power model that relates IT workload and its power dissipation allows optimized workload placement that can save a datacenter roughly $1.4 million in annual energy costs.
Nowadays distributed file systems have to manage billions of small files for applications, and face with more metadata operations than data. So how to provide high metadata performance with such tremendous number of files and such large scale directories is big challenge for distributed file system. We observe that metadata lookup operations dominate metadata workload and incur poor metadata performance...
Transport layer security (TLS) protocol is widely used in e-business and information systems for providing security attributes such as authentication, confidentiality and integrity. However, the certificate-based mechanism which is adopted by most TLS handshake protocols results in complex certificate management overheads and long handshake latency. To overcome these disadvantages, a series of handshake...
The paper explores the new model of Information resource sharing of Personal Digital Library by using such methods as the systems analysis and design and the simulation. Through the technology such as the P2P, metadata and database, it aims to construct the PDL resource sharing platform to implement the effective information resource sharing of PDL in the certain sharing scope such as academic society,...
This paper analyses network security issues for the majority of enterprise-class CMS websitepsilas framework, carrying out safety analyses detailed on all servers by using safety testing tools such as X-Scan. After a detailed study of data, the paper put forward the idea of security evaluation algorithm for constructing enterprise-class CMS.
