Director Architecture
The following diagram shows a schematic view of the architecture of the Director device shown as a Matrix Switch with
filtering. The black dots indicate aggregating Matrix Switch connections between Network Ports and Monitor Ports.

Director internal architecture Figure 1:
Director can be viewed as a matrix switch with up to 28 inputs, or Network ports, and 14 outputs, or Monitor ports.
Any number of inputs can be directed to each of the outputs; Director aggregates the traffic from those Network ports
and sends them to the Monitor ports. For example, the diagram shows:
Traffic from the first in-line Network link (n1.1-n1.2) is being directed to the first SFP Monitor port (m.1) •
Traffic 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)
Traffic from one in-line Network link (n1.11-n1.12) is being regenerated to two SFP Monitor ports (m.9 and m.10) •
The traffic from the in-line Network links to the Monitor ports may include the traffic 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, filters (shown at the bottom of the diagram) are configured independently for each Monitor port, one or
more filters per port, and applied on the aggregated traffic for that port. For example, the second SFP Monitor port
could have two filters, where one filter selects the TCP traffic from the two in-line Network links and the second filter
selects the UDP traffic from the three Span Network ports.
