Network Packet Broker and Monitoring Access Switch

Net Optics Director is an advanced Network Packet Broker (NPB) and monitoring access switch that directs and load balances traffic by customizable filters to specific security, monitoring and management tools across the network. Directing specific types of traffic to specific monitoring tools increases the performance of these tools and allows you to fully utilize the investment in your tools across the network.

Traffic is filtered by Director’s smart filtering engine TapFlow™, based on a variety of parameters such as protocol type, VLAN and address or port, payload content and other packet header information, as well as additional packet manipulation tasks such as VLAN stripping and tagging that help customers deploy tools across the network. Director offers aggregation and regeneration of network traffic leveraging its modular design of 10 SFP ports, up to 4 XFP ports and two modular Director Network Modules, providing 10 daisy-chained units with up to to 380 usable ports. Additional features include filter-based load balancing, ease of management with CLI, Web UI and SNMP management interfaces, central management by Indigo Pro, media type modularity and resilient connections with maximum uptime.

Director Network Models (DNM) are modular bays providing 24 Span Ports or 12 inline network links. Each Director supports two DNMs.  Additional models of Director from the PRO version also provide Deep Packet Inspection functionality that further increases the efficiency of monitoring tools.

Forwarding, Aggregation and Regeneration

Director aggregates traffic from multiple links including multi-protocol aggregated traffic streams and can forward each tool only the data that it needs using customizable filters. Director provides one-to-one, many-to-one, one-to-many, and many-to-many mappings of network links and Span ports to monitor ports. Though traffic is aggregated from many sources, Director provides the ability to track the source of forwarded traffic by both tagging the traffic with the ingress port number and identifying which filter directed the traffic to an individual tool. This enables organizations to achieve cost-effectiveness and efficiency by maximizing utilization of their existing monitoring tools.

Advanced Filtering Options with TapFlow™

Tapflow is a low latency, hardware-based filtering engine that allows forwarding each tool the traffic of interest for its particular purpose, without missing any data. Director supports advanced filtering options including packet headers and protocols (layer 4 filtering) and filtering by VLAN tags and MPLS labels. ROI is multiplied because specialized tools dedicate all their processing power to the tasks they are designed for, preventing oversubscription and contention.  Additional Director Pro models include Deep Packet Inspection (DPI) functionality that provides the ability to apply filters to a packet or multiple packets at any location, regardless of packet length (how "deep" the packet is) or the location of the data to be matched within the packet.

Director Network Modules, Network Packet Broker, NPB


Director offers 2 sets of network modules and 4 input/output 10G ports, all allowing for maximum flexibility. Director offers 2 types of modules. The copper-based module operates at 10/100/1000 in both Span port and inline versions. The fiber module is also available as a Span port version or inline version with all fiber modules offered in multi-mode and single-mode.  Director provides a total of 4 10G ports that can be used either to redirect 10G traffic to multiple 1G monitoring ports or to collect 1G traffic and send it out to a 10G monitoring tool.

Filter Tagging

Filter tagging adds a user-defined VLAN tag to packets to enable tools to identify input streams within aggregated traffic. Director provides the ability to track the source of forwarded traffic by both tagging the traffic with the ingress port number and identifying which filter directed the traffic to an individual tool.

Director, Load Balancing, Network Packet Broker, NPB

Tool Load Balancing

Director can aggregate traffic from multiple network links and load balance the traffic to multiple tools. This ensures that all monitoring tools are utilized efficiently to maximize the monitoring capacity of the entire network. Peak performance network is achieved without investing heavily in additional tools or risking oversubscription. The load can be balanced by IP address, port, protocol, VLAN, and MAC address, or by any other packet header field or its combination.

Director, Daisy Chain, Network Packet Broker, NPBVirtual Chassis Using Daisy-Chaining

With Director up to 10 Director nodes can be daisy-chained together to act as a single logical unit with up to 380 ports and industry-leading total throughput of 740Gbps. Policies and filters are defined on the master and populated automatically among daisy chain members. This allows for increased monitoring leverage and visibility on the network.








Director makes extensive use of modular interface technology to eliminate the headache of matching interfaces between monitoring tools and links. All Director monitor ports use SFP or XFP modular transceivers, so virtually any monitoring tool can be accommodated. In addition, Director Network Modules are available for copper and 10/Gigabit SX(50/62.5µm) or LX(8.5µm) or ZX(8.5µm) Fiber in both in-line and Span versions, increasing the flexibility of media type support.

Director / Director Pro Web UI

Ease of Use

Director provides 3 management interfaces: CLI, Web-based GUI and SNMP. The Command Line Interface (CLI) allows access to Director both locally and remotely (over SSH); a Web-based interface can be launched with any browser and manage a single Director appliance for port and filter management and SNMP can be used to configure, manage and monitor up to 10 daisy chained Director devices. Director supports multiple authentication and authorization (AAA) servers and provides Syslog support for sending log messages to remote servers.





Director keeps traffic flowing even in the event of a power loss using the virtual Zero Delay technology. Director’s two modular power supplies provide maximum uptime and fault tolerance. If one power supply loses power, Director continues operating on the remaining supply. If a power supply module needs replacement, there is no need to take Director offline because the power supplies are hot-swappable. Both universal AC and -48VDC (telco) models are available. 


Director is compatible with all Net Optics Taps and Bypass Switches as well as with all major manufacturers' monitoring devices, including protocol analyzers, probes, and intrusion detection systems.
