We’ve previously talked about the importance of the access layer, aggregation layer and edge to a well-designed network visibility fabric. Tapped traffic from the access layer flows to the aggregation layer, where it’s collected, processed, and then forwarded to the core of the fabric.
The core of the network visibility fabric is where one or more network packet brokers (NPBs) collect and process all flows. It’s in the core that advanced packet processing takes place to send specific data to various monitoring, forensics, and analysis tools. In addition to packet brokering, advanced packet manipulation such as deduplication, decryption, time stamping, packet slicing, and load balancing are critical functions in the core.
Out-of-band security monitoring tools need to ensure that they are only seeing one copy of network traffic. It’s for this reason that deduplication either by session ID or metadata generation is important to 44% of enterprises today. Options to implement deduplication include adding a stand-alone box, or seeing if your NPB vendor has the option to add deduplication as a feature to your NPB.
Load balancing, also referred to as traffic distribution technology is a method of tailoring your available resource to make sure capacity meets nemands. 41% of enterprises rely on L2-L4 load balancing at the core to split network traffic between multiple tools in a manner that doesn’t result in duplication of traffic and helps to prevent oversubscription of the ports.
Garland Technology has taken the approach to deconstruct the network packet broker. Essentially this means that rather than having one box do everything from the packet brokering to the deduplication, we’ve designed products and formed partnerships that handle specific functions to meet the needs of our customers. Our PacketMAX™: Advanced Aggregators combined with Advanced Features boxes to handle deduplication, packet slicing, or time stamping, can meet customers’ needs today and grow with them as their needs evolve over time.
