depending on the standard being used (eg. ethernet, IBM Token Ring, PPP ...). the physical layer encompasses the electrical signals and cabling issues.The data link layer is responsible for transfering discreet packets of information over the physical layer. This layer must be error free and does not deal with routing issues. It can be described as the method in which two PCs communicate over the physical network layer. let us take the Ethernet cards for example. apart from every computer on th
This article describes two network connection modes, bridging mode and routing mode of the Huawei router. If you do not know this knowledge, after reading this article, you will surely know how to set these two network connections. I. Bridging Mode 1. The official professional name of the bridge mode is RFC1483. RFC1483 is designed to encapsulate and transmit multi-protocol packets on the network layer on the ATM network. It is widely used in ATM technology, it becomes the encapsulation standard
