Abstract
This study focused on the data center overload and resource allocation imbalance problem during the task processing of System Wide Information Management (SWIM). The Information-Centric Networking (ICN) technology was adopted in the infrastructure level of SWIM. In order to guarantee the cache performance of ICN in SWIM, and reduce the impact of cache node failure on the network cache performance, a double-layer network structure cache robustness strategy (CRS) based on content popularity and node importance was proposed. Some of the most popular content on the selected special backup node and general node was cached to ensure that a cache node failure would not significantly affect network cache performance. The results of the experimental simulation performed on the ndnSIM platform showed that this strategy is more robustness and has a better cache-hit ratio than other cache methods, which can ensure the network cache performance of the SWIM.
Highlights
The concept of System Wide Information Management (SWIM) was put forward by EUROCONTROL in 1997 and accepted by the International Civil Aviation Organization (ICAO) in 2002 [1]
EXPERIMENT AND RESULTS ANALYSIS in order to verify the performance and robustness of the cache scheme presented, we referred to the SWIM structure that is already deployed by an air traffic management of civil aviation (Figure 4), and a simulation experiment was carried out using the ndnSIM [34] simulation platform
In this paper, in order to solve the potential network reliability problem when the existing information-centric networking cache node failure, we proposed a cache robustness strategy based on content popularity and node importance in this paper
Summary
The concept of SWIM was put forward by EUROCONTROL in 1997 and accepted by the International Civil Aviation Organization (ICAO) in 2002 [1]. As an information sharing platform, SWIM uses a service-oriented architecture It allows interoperability and consistency based on networking and informatization among relevant units of civil aviation and reduces the difficulty of comprehensive scheduling, processing, and integration of data for independent systems. Many studies have evaluated the performance and reliability of traditional network architecture, and some researchers have proposed intradomain-cache cooperation schemes, such as reducing network cache redundancy and network delay and improving cache efficiency [2]. Such measures are rarely considered for use in new network architecture to solve the problem of the TCP/IP network in.
