International Classification:

H04B 10/25
H04B 10/079

Abstract:

A system for monitoring data traversing a bidirectional optical fiber includes a network tap. The network tap includes first and second network ports for bidirectional data transmission over a first optical fiber. The device includes first and second tap ports respectively associated with the first and second network ports. The first network port receives data transmitted in a first direction over the first optical fiber and at a first wavelength and provides the data to the second network port and to the first tap port. The second network port receives data transmitted in a second direction opposite the first direction over the first optical fiber and at a second wavelength different from the first wavelength and provides the data to the first network port and to the second tap port. The first and second tap the first and second tap ports provide the data to one or more network monitoring devices.

International Classification:

H04L 12/24

Abstract:

A switching system includes memory and a switching circuit. The memory stores a port priority table and a trigger source and condition table. The switching circuit for switches network traffic between a number of ports based on the port priority table, the trigger source and condition table, and port health status data. Switching network traffic includes: determining a priority path for a first port using the port health status data and the trigger source and condition table; determining a second port specified as a destination for network traffic arriving at the first port by the port priority table for the priority path; and routing incoming network traffic from the first port to the second port.
