The scheme about compression and encryption is widely used in network traff ic to improve system eff iciency and security. In this paper, we put forward a scheme to demonstrate an optimal implementation on them. We prove that the hardware accelerators and its corresponding latency can be cut in half. If such do not exist, we further propose a novel and more aggressive software scheme, in which encryption is integrated into the compression algorithm. The integrated optimization scheme achieves an average speedup of 40% compared to the 25% achieved by the parallel software scheme, but it suff ers a slight security loss that may not be acceptable for all applications.

Abstract-Electricity is a major cost in running a data centre, and servers are responsible for a significant percentage of the power consumption. With the rising cost of electricity and slow adoption of cleaner electricity-generating technology, servers should become more energy efficient.This paper looks at web servers, as HTTP is a common service provided by data centres. Reverse proxies are commonly used to improve the performance of web servers. In this paper, we consider how reverse proxies might be used to improve energy efficiency. We suggest that when demand on a server is low, it may be possible to switch off servers. In their absence, an embedded system with a small energy footprint could act as a reverse proxy serving commonly-requested content. When demand outstrips its capacity, the reverse proxy can power on the servers to meet this new load. Our initial results indicate that such a scheme could be practical and save significant power on servers with lower load.

Electricity is a major cost in running a data centre, and servers are responsible for a significant percentage of the power consumption. Given the widespread use of HTTP, both as a service and a component of other services, it is worthwhile reducing the power consumption of web servers. In this paper we consider how reverse proxies, commonly used to improve the performance of web servers, might be used to improve energy efficiency. We suggest that when demand on a server is low, it may be possible to switch off servers. In their absence, an embedded system with a small energy footprint could act as a reverse proxy serving commonly-requested content. When new content is required, the reverse proxy can power on the servers to meet this new load. Our results indicate that even with a modest server, we can get a 25% power saving while maintaining acceptable performance.
