At present, tunnelling protocol primarily has two categories : data layer tunneling protocol and network layer tunnelling protocol. 当前隧道协议主要有两种:链路层隧道协议和网络层隧道协议。
Control Model of Earth Pressure for Shield Tunneling Based on Neural Network 基于神经网络的盾构土压平衡控制模型的研究
Through lucubrating the construction process, double shield tunneling machine cyclic operation network simulation models were established. 通过对其循环施工过程的深入研究,建立了双护盾掘进机循环运行网络模拟模型。
Algorithm of multi-trajectory dynamic tunneling training BP neural network 一种多轨道动态隧道技术训练BP网络算法
Unfortunately, this protocol still suffers from many defects. Mobile IP can not work when private addresses are used. Mobile IP's datagram tunneling is incompatible with Network Address Translation ( NAT ). 但传统的移动IP协议还存在许多问题,如不支持私有IP地址,和NAT协议不兼容,在设有防火墙的网络中无法工作,不支持微移动等。
