GENEVE network tunneling protocol Evolution

LAN data transmission has evolved from the original IEEE 802.3 standard to virtual extensible LAN (VXLAN) technology and finally to today’s Generic Network Virtualization Encapsulation (GENEVE) tunneling protocol, which offers improved flexibility and scalability, although it still faces some issues. We look at the three technologies and their areas of application.

Virtual local area network (VLAN) tagging on an IEEE 802.3 network is defined by the 802.1Q standard, which makes it possible to separate traffic from different logical networks within a physical network. Special VLAN tags are attached to each Ethernet frame to assign unique VLAN IDs, allowing a switch to determine the VLAN to which a frame belongs and forward it accordingly. Therefore, traffic from different devices or user groups is separated and isolated without the need for physically isolated networks. Virtual extensible LAN (VXLAN) is a tunneling technology used to create and connect VLANs across a physical network and extend the maximum number of supported 802.1Q VLANs from 4,094 to up to 16 million. Generic Network Virtualization Encapsulation (GENEVE) is a newer tunneling protocol developed by the Internet Engineering…
