During September, I’ve been very fortunate to attend two actual physical conferences focused on 5G. The first was in Denver Colorado, conveniently just across the Rocky Mountains from my current home in Grand Junction. The second was in London England, 200 miles or so south of my original home in Yorkshire (typically celebrated as the home of the most successful cricket team ever, though puddings also get a well-deserved mention). After a number of conversations and sessions at these events, it seems that we can probably stop speculating about the killer app that’s going to drive 5G adoptio ..read more

Driven by latency-sensitive use cases such as virtual RAN, IoT, Secure Access Service Edge (SASE) and Multi-Access Edge Compute (MEC), service providers and data center operators are increasingly deploying compute resources at the edge of the network. Whether these resources are located in traditional telco Points of Presence (PoPs), Converged Cable Access Platforms (CCAPs) or purpose-built micro data centers, they face common constraints in terms of hardware footprint and power consumption. At the same time, with thousands of edge data centers being deployed, operators are under pressure to ..read more

At SuriCon 2019, Eric Leblond and Peter Manev – both of whom are key contributors in the Suricata community – presented important test results, emphasizing the implications of packet loss. Let’s dig a little deeper into the importance of zero packet loss in an IDS deployment. The effect of packet loss on a variety of network analysis gear varies widely based on the function the analysis device is performing. The measurement accuracy of network and/or application performance monitoring devices is affected when packets are dropped by the network sensor. In the case ..read more

This is the first post in a series of performance resilience blogs that we will be producing over the coming months. Performance resilience is the ability to ensure the performance of your commercial or home-made appliance in any data center environment. In other words, to ensure that your performance monitoring, cybersecurity or forensics appliance is resilient to common data center issues, such as badly configured networks, inability to specify desired connection type, time sync, power, space, etc. In this first blog, we will look at deduplication and how support of deduplication i ..read more

In simple terms, a network flow is a series of communications between two endpoints. Beyond these characteristics, however, the definition of a flow may not be totally clear for everyone. When utilized in the context of NetFlow or IPFIX records, most people can agree that we typically define a flow by its 5-tuple attributes (source and destination IP, source and destination port and the protocol field). But it is also common to use either a 4-tuple, dropping the protocol field, or even a 2-tuple, using only the IP addresses. The latter has the advantage that it does work for IP fragme ..read more

Flow records for advanced flow analytics In my blog Packet Capture – the Complete Source to the Truth, I explained why network packets are the ultimate source for reliable network analysis. But as network speeds continue to grow and the number of network packets persistently rocket, it is no longer a viable solution to do “live” analysis and DPI on a packet-by-packet basis. As a consequence, a lot of network monitoring and analysis tools focus on flow records, which they collect from NetFlow/IPFIX probes in the network. Based on these flow records, they are able to detect strange beha ..read more
