A Caching Strategy Based on Control of Traffic Load in the Information-Centric Networking
【Abstract】 Information-centric networking can effectively reduce user delay, server load and link consumption through high-speed in-network cache. However, due to the overload of caching nodes, the replacement rate in these nodes can be too high to guarantee the performance of the nodes and even affects the overall network performance. This paper proposes a caching strategy based on control of traffic load. According to the status of the receiving queue of a node, the replacement rate of the node is dynamically controlled. The content that cannot be cached because of the limited replacement rate is delivered to the downstream idle nodes. According to the result of our experiment, our strategy can help high-load nodes obtain a higher cache hit rate, while improving the utilization ratio of low-load nodes. The caching efficiency in the network is balanced and the overall network performance is improved by implementing our strategy.
