High-Capacity IPFIX Generation for Securing Internet Peering Links
The Internet backbone is a high-capacity network of the world's largest Internet Service Providers (ISPs) peered together into a single seamless network. These Tier 1 ISPs also extend peering connections to other service providers and large content providers enabling universal connectivity around the globe. In any network, however, the most vulnerable point is often where traffic enters and exits the internal network, and this is particularly true for these public Internet peering connections. They represent a strategic location to instrument for security and most organizations inspect the traffic flowing on these links using technologies like NetFlow/IPFIX to help identify and mitigate threats.
Security Visibility Challenge
Network traffic continues to grow at dramatic rates driven by the multitude of connected devices and the increasing array of services, and ISP peering connections are at the epicenter of this traffic growth. Tier 1 ISPs and their peering partners are embarking on network migrations to 100G peering links to meet this demand, but maintaining network visibility at these high speeds is increasingly difficult.
The advancements in networking technologies to satisfy growing bandwidth demand is outpacing CPU performance gains making it more and more challenging to maintain acceptable visibility. Monitoring traffic directly in high-speed switches/routers can adversely impact network performance and often limits visibility. Continuing to utilize
CPU-based probes or Network Packet Brokers through horizontal scaling to expand capacity is quickly becoming cost, rack space and power consumption prohibitive. Other approaches such as traffic sampling to reduce processing burden limits visibility and increases risk. As service providers rearchitect their monitoring infrastructures to support peering link migration to 100G and beyond, new approaches are required to offload and optimize traffic analysis.
Solution: IPFIX Generation for Securing Internet Peering Links
NetQuest's OMX Optical Monitoring Exchange leverages state of the art Field
Programmable Gate Array (FPGA) technology in a purpose-built solution to scale a flow
analysis architecture as links migrate to 100/200/400G.
Real-time IPFIX Analysis to Reduce Time to Threat Detection
The OMX delivers high-capacity IPFIX flow metering and flow record generation for
network security that helps answer the who, what, when and where. The compact
modular design supports up to four flow processing modules in a single rack unit,
with each module supporting unsampled N x 100G flow processing. The OMX also
supports targeting specific flows of interest and packet forwarding to other tools
for deeper analysis.
