Lossy Internet Syndrome (LIS): How Internet Latency is killing your Network


No, this isn’t a medical interest piece. Far from it. However, there may be something to be said about the Internet today as it needs a reality check (up).



No, this isn’t a medical interest piece. Far from it. However, there may be something to be said about the Internet today as it needs a reality check (up).

LIS is a particularly dangerous syndrome affecting enterprises. There was a time when Internet speeds were measured in kilobits per second with 28.8 dial up modems. Downloading movies was unimaginable, and even the smallest document caused a chokepoint. Fast forward to today, when broadband speeds in excess measured in Gbps are not unheard of, in some parts of the world. Internet access speeds and fiber to the home can easily lull enterprises into a false sense of security, encouraging the expanded usage of public Internet infrastructure to drive global enterprise WANs.

But reality hits hard in such cases, especially when these enterprises have branch offices within emerging economies like India, China and Brazil. This is not uncommon in manufacturing, logistics, computer software and business services verticals where outsourcing to low cost destinations is a business imperative. Inherent faults with the use of Internet connectivity, such as peering points and their impact on latency levels, high packet loss and connection drops can make working over the Internet across long distances a nightmare in these locations. Packet loss, especially, can be debilitating for a network as it kills throughput. A quick look at this blog will tell you just how much.
