Aggregation of two 10 Gbit span ports to 1 10 Gbit output with EX2+

This application is normally not possible because the EX2+ has only two 10 Gbit ports and you need 3 to do this job.  But we at Cubro give our units some extra features to do this with two ports.

A optical ports has an transmitter and a receiver part, this two “ports” can be used separately in all Cubro NPB. The other feature what you need is the optical tap at the back.

  1. You must connect the only the TX from the span port with the RX from the EX2+. The TX from the EX2+ are still available.
  2. One of this TX are used as output to the probe.
  3. Because of a security feature, an optical interface did not start sending until it receives light on the RX.
  4. So we use the second TX on the EX2+ to produce this light, (not traffic only layer 1 light)
  5. In this case we need to light sources because we have two span ports, so we use the optical

TAP to split the light in two and connect this with the RX of the span ports.

      Finally you must do a filter input 1 -> output 1 and output 2 -> output 1

EX2 Multi Gbit Cooper aggregation

The Packetmaster EX2 can work as a dual link TAP with dual aggregation output, with filtering and load balancing, at the same time.

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.

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.

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

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.

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.

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

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

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

 

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.

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.
