While enterprises can always build their own middleware , linking this wide a range of devices , managing device - to - device security , and scheduling and coordinating jobs between devices with different levels of computing power can pose thorny problems for grid developers 虽然企业总是可以构建自己的中间件，然而要将这么大范围的设备连接起来，并管理设备之间的安全性，还要在不计算力级别的设备之间调度和协调任务，这对网格开发人员是十分痛苦的。
But the snmp which is the protocol of the application layer requires lower layer working normally and managed devices transmitting ip frames right , so the conventional snmp has been difficult to match the need of the management of the access network 但snmp是应用层的协议,要求下层网络工作正常、被管理设备ip可达。传统的snmp已经很难胜任接入网的网管要求,为此, ieee802 . 3委员会在802 . 3ah协议中制定了专门针对接入网的数据链路层网络管理协议? ? oam 。
