Keysight Technologies, a manufacturer of network packet brokers (NPB) and a provider of solutions to improve network visibility and security, recently announced a pair of 400 Gig products.
Packet brokers intelligently move traffic to the various security and monitoring tools that required network information. Without an NPB, all data is sent to all devices, which requires a product like a firewall to pre-process data before analyzing it. Given the cost of these devices, this might be the costliest way to deploy security and management tools.
