Cisco has doubled the speed of its intrusion-prevention sensor, the Cisco IPS 4270, boosting the rate at which it checks rich-media traffic.
According to a story by Network World's Tim Greene: Cisco uses a new rating system to describe the throughput of the device, giving it a speed for rich-media traffic and a separate rating for transactional traffic. IPS 4270 puts out 4Gbps for media-rich traffic and 2Gbps for highly transactional environments, the company says. It supports as many as 20,000 transactions per second. The ratings for the previous top-end IPS, the IPS 4260, is 2Gbps for media-rich and 1Gbps for transactional environments, the company says.
