Abstract:

In order to process the vast highspeed network data and resolve the load balance caused by user data accessing in cluster storage system, a method of load balance based on NP is introduced. This paper introduces the basic NP principle of series of OCTEON CN56XX, analyzes the primary characteristics of unload balance, proposes a dynamic load balance arithmetic. Through collecting the key factors of node server every third moment or so, each node introduces weights and the capacity, controls task allocation by dynamic feedback to ensure that the new arrivals is assigned with node surplus capacity to the corresponding server. While taking into account the performance and running state of node server, it improves the improvement of whole cluster.

Key words: load balance, cluster, network processor, dynamic feedback, weight
