What is asymmetric routing? Asymmetric routing is a network communication scenario where the forward and reverse paths of network traffic take different routes. In other words, asymmetric routing is the situation where packets from A to B follow a...
The analysis covers Tier 1 carriers widely used by US networks. Datapoints that appear rarely, such as data from Alaska, or a single use of Verizon and/or...
In the previous post we wrote about using PeeringDB to find information about potential peers and obtain the peering details using the REST API with a simple...
As Noction continues to intelligently optimize routing for more and more networks around the world, we find ourselves in the unique position of having great...
At Noction, collecting and analyzing petabytes of data across all IRP instances worldwide offers us valuable data regarding overall Internet performance as...
When networks exchange traffic without having a customer-provider relationship, this is called peering. We've talked about peering in previous Noction blog...
When first starting out with BGP, the typical way to advertise a network's prefixes is using the network statement with a prefix filter and an AS path filter....
While networks are agnostic to the content of the serviced packets, end users have a very good understanding of what traffic they have and what is the...
In most cases, when you have multiple connections to multiple ISPs, you want to use both links side-by-side, with each handling a certain fraction of the...
Here on the Noction blog we've covered many aspects of using BGP to connect your network to the internet. However, often implementing BGP isn't as simple as...
Last year, we discussed the MED attribute and how it can be useful along the local preference and the AS path as a tool for traffic engineering. In this...
One given in the network world is that bandwidth will increase. So that Gigabit Ethernet link that provided bandwidth to spare a year ago may be insufficient...
Before we look at BGP path hunting, let's first discuss the RIP count to infinity problem. RIP, the Routing Information Protocol, is pretty much the simplest...
