Dealing With the Data Deluge: Accelerating Packet Capture
The digital universe is doubling in size every two years, and digital data volume is projected to reach 44 trillion gigabytes by 2020, according to IDC. Not only is there exponentially more data than ever before, but it’s coming in faster than ever – at network speeds up to 100Gbps. This poses clear challenges for network professionals who need new types of tools to protect the network.
Packet capture (PCAP) is a fundamental tool to help engineers and administrators manage and secure large and small-scale networks alike. A mechanism for intercepting data packets that are traversing a computer network, PCAP is a common capability deployed within an organization to monitor security events and network performance, identify data leaks, troubleshoot issues and even perform forensic analysis to determine the impact of network breaches.
However, current PCAP systems using commodity network interface cards (NICs) are not equipped to deal with the demands of performing precision capture and replay at 10/40/100 Gbps speeds.
A ray of light shines, though, to give hope to network administrators. There are solutions today that have been built to facilitate packet capture at speeds topping 100 Gbps. The use of network acceleration technology, coupled with open source network monitoring and capture solutions, can enable organizations to keep up with the demands of precision packet capture and replay on high-speed networks.
