In the vacuum of two network engineers arguing, there are non-existent ideal situations where networks are built, grow or shrink congruently, and never have bugs. In perpetuity. Forever and ever. Amen. The Forces of Evil From the moment we conceive of a network and through the end of it’s life, there are numerous competing forces […]

What if your network was more than just a collection of hardware and cables strung together over the years to solve specific problems? What if your network was agile enough to empower your business today and offer deep insight into the flow of information throughout your data center? What if this network could adapt to your changing business needs at the drop of a dime and help ensure no opportunity slips through the cracks?
Sounds like a dream, but in fact its very much possible today.

This post is a written version of the presentation I recently gave at NANOG, and complements the series I’ve been doing on BGP security as a case study. Part 2 should publish next week; I’ll post a link to it here when it does.

Introduction
In the previous post I showed some of the options two interconnect two AS so that a customer can buy a VPN in two different locations from two different SPs. There is another technology called Carrier Supporting Carrier or Carrier of Carriers. This technology is used when a customer buys a circuit from an SP, Internet service or L3 VPN and that SP uses another SP to carry their traffic between the locations. The SP connecting the customer is then the customer carrier and the SP providing the backbone is the backbone carrier. It is also possible to combine CSC with the Inter-AS options in the previous post, I will show an example of this being used in a real life network in the research world.
Carrier Supporting Carrier
CSC is a technology used to expand the reach of a SP by using another SP as transport. The concept is shown in the following diagram.
The customer carrier is providing a service to the customer. It can be an Internet service, MPLS switched or not or an MPLS L3 VPN. The CSC VPN service provides MPLS transport for the customer carrier. It is also sometimes referred to as Continue reading
In this article, I’m going to pay specific attention to information processing via Tarantool queues. My colleagues have recently published several articles in Russian on the benefits of queues (Queue processing infrastructure on My World social network and Push messages in REST API by the example of Target Mail.Ru system). Today I’d like to add some info on queues describing the way we solved our tasks and telling more about our work with Tarantool Queue in Python and asyncio.
