交换机基本介绍（分类、性能指标、硬件构成及工作方式）一、交换机的分类与性能指标 1.1交换机的分类按照网络构成方式来分的话，交换机分为三类：接入层交换机、汇聚层交换机和核心层交换机。按照OSI模型来划分的话，分为：二层交换机、三层交换机和四层交换机还有一种按照硬件形态来划分，可以分成两类：盒式交换机和机框式交换机。盒式交换机是一种有固定端口数，有时也会带有少量扩展槽的交换机。机架式交换机是一种插槽式的交换机，这种交换机扩展性较好，可支持不同的网络类型，可支持更大端口密度的网络。一般在数据中心的接入层都会采用盒式交换机，盒式... 阅读详情

确定是以下两个Thread占用过高，求问如何解决？
