Abstract
A system and method for supporting subnet management in a network environment is described. The system and method can be used in an engineered system for middleware and application execution, or a middleware machine environment. The system can associate a subnet administrator (SA) in a subnet with a plurality of SA proxies, each of which can receive plurality of requests from one or more client nodes. The SA can handle the requests, which are forwarded from the SA proxies. Additionally, each client node can be assigned a dedicated queue pair (QP) number, so that there is no need for always sending an initial request to a pre-defined well-known QP number.
