The network is the eco-system connecting everything together, carrying content between users, applications and data stores. It contains the authoritative record of all activity, all interactions and all communications from all connected entities in the ecosystem.
The network is the eco-system connecting everything together, carrying content between users, applications and data stores. It contains the authoritative record of all activity, all interactions and all communications from all connected entities in the ecosystem. If you're an online business, everything you need to know it can be found in your network, in true real time. Not just the time-sensitive and critical application traffic you expect to see and care about; but it also a ton of other traffic you care less about, such as unsolicited web traffic, media streaming, file transfers, backups and so on. All this data interacts together in the network and competes for resources. Your network also carries vital information about the health of your infrastructure as a whole. Routers and switches continuously share link state and reachability information and high availability, and load balancing protocols that support out real-time applications also signal across the network.
What a minute?! You already know this? So why hasn't everybody fully leveraged the power of network data in looking after the health and performance of their web and mobile applications and online businesses? Because it's hard. Until now, it's been very difficult, time consuming and costly to deal with packet data--to passively extract it, decode it, index it, make it searchable and, most importantly, to easily make sense of it! Wouldn't it be great to be able to just tap into network data and get instant operational, customer and business insights that are actionable and trusted?
As it turns out, really accurate timing is critical for understanding things like customer experience, transaction performance, network latency, component Latency (ie firewalls, load balancers, applications) and service provider performance. The actual fact is that only Corvil network data analytics takes care of time synchronization. It records sub-microsecond timestamps for every packet and also accepts time-stamped traffic from all of the network packet brokers, including: Cisco, Arista, Gigamon, Apcon, cPacket, VSS & Ixia. And, if you haven't deployed PTP or have GPS in your data centers, don't worry. Corvil has solved that too, providing time-synchronization between your locations!
Look, today’s networks are really complex, with multiple physical paths for redundancy and complex routing methodologies to direct the traffic. And, it's just going to get worse. Application traffic doesn't always take the optimal path we would expect leading to unexpected and intermittent application performance. Wouldn't it be great to be able to record where every packet was seen, providing immediate insight into the operation and efficiency of the network infrastructure?
Packet Loss is an application and revenue killer for online business, causing high transactional latency and degraded user experience. If data is lost within the network, TCP automatically initiates a retransmission after a timeout period. This occurs in the network stack, the application itself is unaware of the loss so pure IT Operations solutions are blind to these effects over-optimistically reporting application performance. Talk about trying to find a needle in a haystack! Actually, trying to pinpoint packet loss that has trashed customer experience on your retail E-commerce site or brought down the global executive team VOIP call is super stressful if you're the network engineer in charge of the network, isn't it? It could very well not be your network's fault either. Could be something wrong with an application or the service provider. When the business is breathing down your neck, you need to find the problem and fix it--FAST! With a deep level of network data understanding, sub-millisecond time stamping and micro-visibility analytics, network engineers armed with Corvil network analytics can troubleshoot and solve issues 10X faster, usually in minutes vs. hours or even days. I think it would be much more fun to be the hero, rather than the fall guy. What do you think?
