Layer 1 Solutions

TAPs | Bypass Switches | Media Converter

A TAP (optical or electrical) is the first device to provide network visibility. It is vital that this device is highly reliable and offers best performance. Cubro provides the best quality for an affordable price. Many of the Cubro layer 1 devices provide unique features. Cubro provides Optical TAPs, Copper TAPs and Aggregator TAPs which are designed to enable flawless in-line monitoring of 1G, 10G, 40G and 100G networks. These TAPs offer 100% visibility to link traffic to security and network monitoring tools.


Layer 2-4 Solutions

Aggregation | Load balancing | Traffic steering | Packet filtering | Packet encapsulation | Packet de-capsulation

The network packet broker handles the traffic typically between layer 2 and 4. A packet broker must be very fast, and capable to handle massive amount of data up to multiple terra bit. Cubro products offer a wide variety of feature set and bandwidth options. From small units with a few ports to several 100 Gbit ports - all these units are non-blocking and can handle the traffic in line speed.


Layer 2-7 Solutions

Load balancing in all layers | Packet filtering in all 7 OSI layers | Packet modification in all 7 OSI layers | Keyword search | Regular Expression search | XDR generation | Probing application | Network statistics

Network bandwidth is growing exponentially and monitoring is more and more a challenge. Cubro is helping to fill the gap between better performance and reducing the cost of ownership. Layer 7 filtering and traffic handling gives the ability to filter on application layer to find the communication of specific applications. These products provide network visibility required for lawful interception, internal and external security, fraud, etc. The Cubro Probe can filter on packet and session level.
