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.

384 x 10 Gbit ports cross connect

We use 6 Packetmaster EX 20400 to realize this 384 x 10 Gbit port cross connect !

  • 400 Gbit backbone
  • tunneling via VXLAN
  • non blocking
  • any to any & many to any & any to many support
  • easy expandable

 

Stacking Packetmasters

Customer Solution!

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

100 Gbit LR4 multiple splitting

Sometimes it is needed to tap a 100 Gbit LR4 link more than one time, this is not easy because the optical budget is too small to do that.

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.

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

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.

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.

 

Aggregation of an 10 Gbit link and output to an 10 Gbit port

Aggregation of one 10 Gbit link with optical splitter to 10 Gbit fibre output
