Ethernet over SDH applications

Purpose
This section gives an introduction to the possible TransLAN
®
Ethernet over SDH
applications.
Types of applications
Layer-2 switching allows different types of applications, including:
• Ethernet point-to-point transport
• Ethernet point-to-point transport in buffered repeater mode
• Ethernet multipoint transport (dedicated bandwidth)
• Ethernet multipoint transport (shared bandwidth)
• Ethernet multiplexing (VLAN trunking)
TransLAN
®
supports all Ethernet transport solutions. Specific system configuration is
required for each network application.
Direct interconnection of two LANs - Ethernet point-to-point transport
The most straight-forward Ethernet application on the TransLAN
®
equipment is a
leased line type of service with dedicated bandwidth to interconnect two LAN
segments which are at a distance that cannot be bridged by using a simple Ethernet
repeater, because the collision domain size rules would be violated.
The two interconnected LANs need not be of the same speed; it is possible to
interconnect a 10BASE-T and a 100BASE-T LAN this way for example.
