GRE de - encapsulation

Virtualisation is a very common approach in data centers, but for monitoring purposes it is somehow not so easy, because the network communication within the hyper visor is not transported over the physical NIC in the server, it is transported over the virtual switch. Thus, there is no access to this traffic.

It is common to use virtual taps to solve this issue. But this virtual taps can not send out the traffic straight, they use in most cases a GRE tunnel.
GRE is a L2 transparent tunnel.

Layer 1 Media Conversion

The Cubro 1/10 Gbit Media converter is a nice a simple tool to solve many problems in the daily network business. You can select the media by changing the SFP. The unique design supports also CWDM / DWDM and BIDI SFP.

Amplification

You can enlarge the transfer range of your media dramatically without risking errors on your data. The examples below show some common options, but a lot more combinations are possible.

Stacking Packetmasters

Customer Solution!

Request: aggregation and filtering traffic for monitoring system 32 x 1 Gbit links & 10 x 10 Gbit links

GRE de - encapsulation

Virtual environments needs virtual Taps, virtual Taps need GRE to send it over the virtual switchto a real monitoring device. All Packetmaster units can decapsulate GRE traffic to get the data in their original format.

STP Monitoring multi 100 Mbit links

To monitor hundreds of 100 Mbit links, like on an SMS centre or on an STP, Cubro offers and flexible and price wise solution with 100 Mbit Flextap and Cubro Packetmaster EX5-2 as aggregator and filter device.

Packetmaster as Patchfield

The Packetmaster EX can be used as intelligent patch field. This is feature is possible because the EX has no designated in and out port configuration. Each port is an input and an output at the same time.

EX2 10 Gbit monitoring with load balanced output

Use the integrated optical TAP to connect to the live link and use the load balancing features to monitor the traffic

EX2 media & speed converter

In this very simple solution the Packetmaster EX2 works only as a bidirectional media and speed converter. The size and the fan less construction, makes the EX2 the flexibles’ and cheapest device on the market.

aggregation 40 x 10 Gbit links with one EX 20400

Cubro now offers a "NEW" Packetmaster solution with 80 x 10 Gbit Ethernet ports.
The base unit is the EX 20400 with a new firmware that gives us the possibility to convert
a 40 Gbit port into 4 independent 10 Gbit ports.

Cubro NPB units support bypass function

The Cubro Bypass Application is a superior way to provide a fail-safe access port for an in-line monitoring appliance. From EX2 with Gbit up to EX 20400 with 100 Gbit bypass feature. With and without optical layer 1 switch support.

 

Monitoring offload

The smart Cubro solution to use your existing monitoring system even when your data traffic is growing exponential !

  • Reduce Monitoring cost by off-loading the existing monitoring system.
  • Reducing not only Capex also Opex goes down because of less hardware resources.
  • Still the full metadata information on user plan traffic.
