变长子网掩码(VLSM)在油田局域网中的应用

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。

VLSM(VLSM)applied in the oilfield in LAN

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.
