变长子网掩码(VLSM)在油田局域网中的应用

VLSM (VLSM) applied in the oilfield in LAN

在采油厂中随着网络覆盖面的不断扩大,局域网也随之增大,这些必然引起局域网流量的增大、网络性能的下降、及管理的困难等等一系列问题。为了解决这些问题,就要对现有的局域网进行合理的划分,对现有的IP地址进行合理的分配和管理。虚拟局域网(VLAN)、变长子网掩码(VLSM)是解决子网划分的关键技术,使用这些技术和方法可以实现局域网的优化和简化局域网管理。

in the oil production plant with network coverage continues to expand, local area increases, these will cause the increase of LAN traffic, network performance degradation, and management difficulties and so on a series of questions. In order to solve these problems, it should be a reasonable division of the existing local area networks, allocation and management and reasonable in existing IP address. Virtual local area network （VLAN）, variable length subnet mask （VLSM） is a key technique to solve the subnet division, the use of these techniques and methods can achieve LAN optimization and simplification of LAN management.
