Cubro TCO

Total cost of ownership 

Since the late 80’th the total cost of ownership is a well known buzzword, in many presentations around the world. But Cubro offers really TCO reduction. We offer 2 years’ hardware warranty included, the lowest support cost, no additional port license cost, no additional software license cost, many unique features. Total cost of ownerships comes along with good planning, good free of charge feature set, and customisation. 


Customisation to help saving cost . We listen to our customers! One of many advantage choosing Cubro is we are flexible with the design and functionality of our products. Our modular hardware and software concepts help us to easily and quickly design custom solutions for our customer's needs.

But customization is also related to a most flexible product design, and good support. Today products are very complex and often offer features and functions which are not known to the customer. A good support leverage the value of the tool, instead on buying additional equipment!

Open NPB 2

A Network Packet Broker is a tool which normally work in a system together with other tools north and southbound. That is the reason why we give our units many options to customize the Cubro Packetmaster to customer’s needs.

  • Fully installed Debian Linux,
  • root access,
  • CLI, WEB Interface,
  • Rest API
  • Python and Perl script.
  • Script examples
  • change filter at link status change
  • read a file from an external device and change configuration
  • send mail with statistic data
  • send packets out for trouble shouting
  • and much more

Cubro Visibility Solution

Monitoring iconNetwork visibility is a success factor running any kind of Networks from enterprise to large service provider networks. Not only performance but also fraud and security applications are a part of the Network visibility infrastructure. 

Network visibility is a network with in the network, and this part can be very complex many devices from different vendors must be controlled smoothly from one single point, to keep the opex cost down and the visibility network stable running. 

We know monitoring is a must to run networks, but monitoring must become smarter. Smarter and more flexible, and cheaper.  Monitor only what you need, in terms of legal and cost.  Monitor the entire network but keep the cost and the management afford under control.

Packet Slicing

Packet slizing

Packet slicing means to cut of the payload of an Ethernet packet for monitoring purpose, the reason could be save bandwidth and capture space on the disc. The other reason is security to protect customer payload
to me monitored if not necessary. Typically packet slicing is an expensive add-on in NPB and has typical a reduced bandwidth because it is realized with NPU Processors.

Not in Cubro G4 Units it is included free of charge, up to multiple 100 Gbit.  read more

Inline bypass solution

Bypass Switches provide fail-safe inline tool protection for your security and monitoring devices.

The last software upgrade gives every Cubro Packetmaster the ability to work as a bypass switch with heartbeat functionality. The Cubro Bypass solution supports data rates from 1 to 100 Gbit.

Symmetric load balancing

balancing balls smallSymmetric load balancing, or session aware load balancing, is supported on all Cubro G4 Packetmasters (EX32 … EX 20400) at no extra charge. In addition, 10 LB groups with 16 ports are also supported.

Symmetric load balancing is a mechanism that interchanges the source and destination addresses to ensure that bidirectional traffic specific to a particular source and destination address pair flows out of the same member of a trunk group.

Layer 7 Filters

osilayers 7All EX Packetmaster can be used with thousands of filters, with ZERO performance loss. Almost all of the fields in the IPv4 and IPv6 layer 4 header can be used as a filter match. However, sometimes filtering is needed above layer 4. Filtering up to layer 7 is now possible with the new Cubro Session Master EXA series. The Session Masters units utilize on board Network Processors, which are are highly optimized CPU's that allow the Session Master to easily handle high bandwidth network traffic with no lost or dropped packets.  Layer 7 Filter

Cubro Consulting

Taps and Network Packet Brokers have come a long way, and as a result network designers are now able to implement complete solutions for aggregation, filtering, shaping, load balancing and much more. In order to satisfy different monitoring requirements and provide  different monitoring systems with the specific traffic needed, a network tapping system is often a desired part of the plan. However, extensive networking knowledge of the OSI-model from Layer 1 to Layer 7 is needed to properly plan and deploy such systems. Strategic and anticipatory planning minimizes TCO and guarantees a flawless and secure network environment. Cubro is proud to offer pre and post sale support on planning and reviewing new and existing Tapping and Monitoring Systems.
