Point-to-Point Overview and Technical Specifications

PacketFabric’s point-to-point service is a dedicated Ethernet Private Line (EPL).

Commonly referred to as “pseudowire,” EPL is a traditional point-to-point Ethernet virtual connection between physical interfaces.

Single point to single point

The most obvious difference between a point-to-point connection and a virtual circuit is that point-to-point connections are dedicated.

This means that while a PacketFabric access port can have up to 4,000 virtual circuits, a point-to-point interface will only support one EPL connection.

Pricing

Point-to-point connectivity is our most economical service and the closest thing to a ‘bundled’ product that we offer. Each point-to-point connection includes two access ports and dedicated data transfer costs.
