Products - Net Optics - Case for Taps

A
Network TAP
provides a "
Test Access Port
" for
analyzing high-speed networks
in half or full duplex mode. When operating high-speed, high-capacity, data communications systems it is often necessary to monitor and analyze traffic with an absolute minimum disturbance to the data stream.
Network taps
provide inexpensive, permanent access ports throughout the network, enabling
monitoring and analysis
without interrupting transmission.

TAPs Versus Span Port Connection


To enable
monitoring and intrusion detection
, most of the major switch vendors now support span (or mirror) ports on their switches. This allows the traffic to be sent to an analyzer port as well as the original designated port.

A Span Port solution has three major drawbacks.
  1. First, it puts an increased load onto the switch that often increases CPU or memory requirements.
  2. Second, when packets are sent to a span port, most vendors' switches remove low level (Layer 1, select Layer 2) errors from the stream of data. This makes low level troubleshooting impossible.
  3. Third, if the link is a full duplex link running at full line rate, then to mirror this data would require a span port running at full line rate to get both directions of traffic. Unless a non-blocking switch is being used, large amounts of data could be lost because span port traffic is a low priority.
The tap solution for
network monitoring
and intrusion detection utilizes passive fiber or copper splitter taps on the main network links. This solution mitigates the trouble and expense associated with the three drawbacks mentioned above.

TAPs Versus In-Line Connection


Another common solution for monitoring and intrusion detection is to attach the
analyzer in-line
.
An in-line solution has two major drawbacks:
  1. First, because it is not cost effective to leave an analyzer in-line, network managers must break a connection whenever they need to monitor.
  2. Second, because the analyzer is not passive, attaching an analyzer in-line introduces a point of failure into the network.

The permanent,
passive tap
solution eliminates the risk and inefficiency associated with monitoring with an in-line analyzer connection.

Flexibility


Network taps provide network managers with the flexibility to monitor all aspects of the network 24/7. As network security and reliability continue to grow in importance, taps are an integral solution for any network.

Tap Types


Taps come in several varieties with different purposes and features. If you are confused about what type of Tap device you need in your network, here is a quick overview of the capabilities each type of Tap provides:

Network Taps

Network Tap - TP-CU3 When a monitoring tool is needed, simply connect the device to the Network Tap instead of taking down the link, moving cables, and causing traffic interruptions. Even if Taps lose power, they are completely passive and feature fail-open technology that ensures traffic continuity. Network Taps pass all network traffic - including Layer 1 and 2 errors - without introducing bottlenecks or points of failure for 100% visibility.
Regardless of where in the network or the types of interfaces that need to be monitored, Net Optics has a Tap solution. Copper, multimode and singlemode fiber, and coax are supported, at speeds up to 10Gbps. Media conversion models are also available to support disparate interface types.

iTap

iTap - IPA-CU3 The iTap operates just like a standard Tap, with the extra capabilities of remote management and basic monitoring built directly into the Tap.

Port Aggregation Taps

Port Aggregation Tap - TPA-CU3 A Port Aggregator does essentially the same thing as a Tap; it allows you to access a single network segment. The difference is that you can plug in one or two monitoring devices (depending on the model) and view full duplex traffic with only a single NIC per device, rather than two NICs.

Link Aggregation Taps

Link Aggregation Tap - LA-1400 A Link Aggregator does essentially the reverse of a Regeneration Tap. This device accepts multiple network segments and "aggregates" all the traffic to 1 to 24 monitoring devices (depending on the model).

Regeneration Taps

Regeneration Tap - RGND-SX-S8 Net Optics Regeneration Taps provide permanent passive monitoring access ports for 100% visibility into your network's critical links with multiple devices. Compatible with all leading security and network management tools, Regeneration Taps support simultaneous passive deployment of intrusion detection and prevention systems, protocol analyzers, RMON probes, and other key devices. Each monitoring device connected to the Regeneration Taps sees the same traffic at the same time, providing a complete picture of link health for troubleshooting and analysis.

Bypass Switches

Bypass Switch - IBPO-HBLR-XFP Net Optics“ Optical Bypass Switches provide a permanent and trouble-free access port for in-line network security and monitoring devices. The Optical Bypass Switch automatically switches network traffic through added in-line devices or bypasses devices that are about to be removed. With a heartbeat, the Optical Bypass Switch protects network traffic against both signal and power loss on the attached in-line device.

Converter

Converter Tap - CVT-SX5/GCU Complete your passive monitoring solution with our full line of converters, test equipment, cables, and more.
  • Media converters for mixed link types
  • Power chassis' options
  • Rack panel frames, and fiber optic cleaning kits

Director™

 Director™ - DIR-7400 Take control over your mission-critical, high-speed converged networks with Director, a new monitoring and data aggregation solution from Net Optics, the leader in monitoring access.

Director connects dozens or hundreds of critical high-volume data links to a sub-station of monitoring tools, enabling you to send just the traffic of interest from any links to any tools you choose, with remote, dynamic control.

xBalancer™


xBalancer Net Optics xBalancer™ helps IT with (NLB) Network Load Balancing for monitoring high-speed networks. As a cost-effective way to share the increasing traffic load among multiple inline tools.

Recording and inspecting all traffic on high-volume 10G networks puts pressure on organizations to either invest heavily in new 10G tools or risk oversubscription. Now, xBalancer enables two or more appliances to be deployed in parallel with traffic balanced between them - a low-cost solution for using IPSs, firewalls, Web accelerators, and other inline appliances more efficiently and avoiding tool oversubscription that could affect service level agreements.
xBalancer further raises the efficiency of inline appliances by sharing a pool of them across multiple independent network links.

NEW Phantom Virtual Tap

Phantom Virtual Tap The Phantom™ Virtual Tap is a landmark innovation in network traffic monitoring for virtualized and cloud computing environments. This rich-featured software Tap is a vital resource for streamlining security, management, and compliance.
Tapping traffic between virtual servers (VMs) on a physical server, it delivers unprecedented total visibility into traffic passing between VMs on hypervisor stacks. The Phantom Virtual Tap replicates traffic passing between virtual network interface controllers (NICs) and pushes it out to both virtual and physical monitoring devices for maximum versatility.
This Tap is the only solution on the market from a monitoring access vendor that addresses both physical and virtual environments.
Net Optics Phantom HD Data centers are virtualizing at breakneck speed, but the monitoring infrastructure often struggles to match that pace.
Now, Net Optics' Phantom Solution™ uses the Phantom HD™ appliance to ease the virtualization transition by converging the physical and virtual monitoring infrastructures.
The Phantom HD™ terminates encapsulated traffic from Phantom™ Virtual Taps or other sources. It decapsulates the traffic and defragments those packets that occasionally become fragmented during tunnel encapsulation.
