Abstract
Described is a system and method of protection switching in an Ethernet network. First and second point-to-point Ethernet links are established to data equipment. Identical streams of Ethernet traffic are received at a first Ethernet port and at a second Ethernet port. The stream of Ethernet traffic being received at the first Ethernet port is transmitted to the data equipment over the first point-to-point Ethernet link, while the second Ethernet port is prevented from transmitting the stream of Ethernet traffic received at the second Ethernet port. During a protection switch, transmission of Ethernet traffic ceases over the first point-to-point Ethernet link, and commences over the second point-to-point Ethernet link, the second Ethernet port transmitting the stream of Ethernet traffic being received at the second Ethernet port to the data equipment.
