What is a Network Packet Broker?

A Network Packet Broker (NPB) is a device that optimizes the flow of traffic between TAP and SPAN connections and network monitoring, security tools. The packet broker collects traffic from single or multiple network links, filtering and distributing each individual packet to the correct network monitoring tool by load balancing, which enhances the performance of network analysis and security tools.

Why do you need a Network Packet Broker?

In the past, tools would directly attach into the production network through these TAPs or through mirror/SPAN ports. However, with the growing volume of data and the increased mobility of users, devices and applications, tools are having a harder time providing accurate and timely analysis. Network Packet Brokers help you optimize the performance of your monitoring and security tools across the entire network by giving each tool the right packet data, which results in an increase of network efficiency while reducing your costs.
The FS Network Packet Brokers designed for aggregation, filtering, and routing of multiple 1/10/40/100G inputs, used in high sustained bandwidth port monitoring and analysis scenarios.
They bring you the power and flexibility of network traffic management, enhance the performance of network analysis and security tools, helping you solve application performance bottlenecks and troubleshoot problems on the network.

FS Network Packet Brokers FAQs

  • Q:  How does the Timestamp feature of the Network Packet Brokers help me?


    Through the source port and timestamp information carried in the packet, the server cluster can know the exact time consumed by the packet at each layer of the data center. The port number identifies the device from which the traffic is coming, and the time stamp of each device calculates the network delay.

  • Q:  I don't understand the message truncation function of the Network Packet Brokers, can you explain?


    The message truncation function truncates the received traffic to a packet of 64 to 128Bytes before it is forwarded from the egress. In this way, only the packet header information can be sent to the security device or the traffic analysis device, which can effectively reduce the burden of the back-end analysis system. At the same time, the information carried by the layer is not applied, thus achieving the effect of traffic desensitization.

  • Q:  If there are multiple collection points and traffic is sent to the analysis device, how does the Network Packet Brokers tell the analysis device which collection point the traffic is coming from?


    Different vlans can be used to mark traffic collection ports to carry this information.

  • Q:  Can the VxLAN/GRE message be processed?


    Yes, the Network Packet Broker can decapsulate the VxLAN header information and divert traffic to specified devices. You can also Tag the decapsulated traffic to carry tenant information.
