Director internal architectureFigure 1:

Director can be viewed as a matrix switch with up to 26 inputs, or Network ports, and 12 outputs, or Monitor ports.

Any number of inputs can be directed to each of the outputs; Director aggregates the trafc from those Network ports

and sends them to the Monitor ports. For example, the diagram shows:

Trafc from the rst in-line Network link (n1.1-n1.2) is being directed to the rst SFP Monitor port (m.1)•

Trafc from two in-line Network links (n1.3-n1.4 and n1.7-n1.8) plus three Span Network ports (n2.3, n2.7, •

and n2.11) is being aggregated and directed to the second SFP Monitor port (m.2)

Trafc from one in-line Network link (n1.11-n1.12) is being regenerated to two SFP Monitor ports (m.9 and m.10)•

The trafc from the in-line Network links to the Monitor ports may include the trafc being received at the odd-

numbered Network port (at the left side of the diagram), at the even-numbered Network port (at the right side of the

diagram), or both; the diagram doesn't include this level of detail.

In addition, lters (shown at the bottom of the diagram) are congured independently for each Monitor port, one or

more lters per port, and applied on the aggregated trafc for that port. For example, the second SFP Monitor port

could have two lters, where one lter selects the TCP trafc from the two in-line Network links and the second lter

selects the UDP trafc from the three Span Network ports.
