Absolute visibility across all 
Open Systems Interconnection (OSI) layers

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 optimum 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 typically handles the traffic between layers 2 and 4. A packet broker must be very fast, and capable of handling a massive amount of data up to multiple terabytes. Cubro products offer a wide variety of feature sets and bandwidth options. From small units with a few ports to several 100 Gbit ports - all of 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 presents more and more of a challenge. Cubro helps to fill the gap between better performance and reducing the cost of ownership. Layer 7 filtering and traffic handling provide the ability to filter on application layer to find the communications of specific applications. These products provide network visibility required for lawful interception, internal and external security, fraud, etc. The Cubro Probe can filter on the packet and session level.

Packetmaster EX484-3

The Packetmaster EX484-3 is a network packet broker and network controller switch that aggregates, filters and load balances network traffic sent to network monitoring, security and management tools. The EX484-3 allows you to filter and load-balance traffic from 10 or 40 Gbps links to multiple 1 Gbps monitoring tools or aggregate multiple 1 Gbps links to 10 or 40 Gbps monitoring tools. The EX484-3 supports traffic modification as well as changing, removing and adding VLANs.

Success Story: Cubro provides a cost-effective solution for 10G interfaces to a Data Centre

End to end visibility, high density performance with EX484-3

A data centre is often over crowded. The main requirement of a data centre customer was to deploy a network packet broker that covered all interfaces, provided high density performance and saved rack space. Cubro’s EX484-3 was the perfect solution and provided end to end visibility without compromising on any of the other requirements. The Packetmaster has 72 ports in one U, which is an ideal solution to save rack space. The EX484-3 provides high density solutions to the growing network of the data centre. This product is designed to optimize performance and provides excellent value for the money.

The EX484-3 supports separate RX and TX usage. This feature provides flexibility and doubles the number of ports. Each SFP port has a receiver and a transmitter. Two receiver ports on the Packetmaster are used to monitor each link. The two transmitter ports are not used but the Cubro units can use these ports as independent output. This means that all the ports can be used to receive traffic while all transmitters are still being used to provide output to the monitoring tools.

Cubro’s network packet brokers are capable of steering traffic in many ways. The tools are passive and are deployed in-line behind TAPs. They can be used with or without bypass protection. Steering includes load balancing and traffic tunnelling. Cubro supports all major tunnel techniques including VLAN, MPLS, GRE, NVGRE, GENEVA and VXLAN. TAP networks today can be very complex, as there are often several packet brokers involved.
