Load-Balancing Multipath Switching System with Flow Slice
Journal Title: INTERNATIONAL JOURNAL OF COMPUTER TRENDS & TECHNOLOGY - Year 2013, Vol 5, Issue 4
Abstract
Load balancing plays a pivotal role in core routers as they need to handle multiple requests at a time. To achieve load balancing Multipath Switching Systems (MPS) are widely used. One of the challenging issues in building MPS is to ensure load balancing across multiple paths besides keeping the order of intraflow packets intact. The existing solutions are packet – based and they have drawbacks as they cannot scale and cause delay. Hashing algorithms that are based on flow-size also could not perform well due to improper distribution of flows. Recently Shi et al. presented a scheme “Flow Slice” to overcome this problem. According to this scheme each flow is cut into multiple slices based on a given threshold. In this paper we built a prototype application which is a custom simulator that demonstrates the usefulness of FS scheme in terms of load balancing efficiency. The experimental results revealed that the FS scheme is effective in load balancing.
