1.1.2 Link layer protocols
The link layer provides reliable transmission of data from one site to another. The link layer
receives packets from the network layer and then encapsulates packets into frames to deliver
them to the physical layer.
The Nortel Secure Router 8000 Series supports LAN link layer protocols as follows:
• The Virtual Local Area Network (VLAN) divides a physical LAN into several logical
subnets, regardless of their physical locations.
• Data transmission within a VLAN does not interfere with that in other VLANs. This
enhances the network security.
