SNMP data is also used by network engineers to troubleshoot reported problems along with network architects to do things like capacity planning. The flow analytics are used to make decisions on how traffic is being sent or received to other internet-connected peers via traffic engineering and optimization.

Dozens of policing agencies are currently using cell-site simulators (CSS) by Jacobs Technology and its Engineering Integration Group (EIG), according to newly-available documents on how that company provides CSS capabilities to local law enforcement. Once a nonce is reused, AES-GCM completely falls apart.

The cost increase prompted our engineering team to investigate alternative ways to provide the same level of service more efficiently. Internal Envoy routers allow communication between the global cell and replicated cells. This approach enables us to reduce the blast radius of a single-cell failure.

Last month at DENOG11 in Germany, Kentik Site Reliability Engineer Costas Drogos talked about the SRE team’s journey during the last four years of growing Kentik’s infrastructure to support thousands of BGP sessions with customer devices on Kentik’s multi-tenant SaaS (cloud) platform. IPv6 peerings are starting to outgrow a single node.

In this article, I want to underscore why NetOps has an integral role (and more responsibility) in delivering on the promise of reliability and highlight a few examples of how engineering for reliability can make networks less reliable. This is no small feat and can lead to significant overhead and resource consumption.

However, this type of networking model with a flat IP network across the entire Kubernetes cluster creates new challenges for network engineering and operates teams. Google Compute Engine (GCE) - all pods can reach each other and can egress traffic to the internet. Open Virtual Networking (OVN) (Open vSwitch community).

ingested into the Kentik Data Engine with two new fields that represent the Device (router) and Site (PoP) where that flow will exit the network to an adjacent autonomous system (AS). Enhancing each flow record with data about its exit router/site is just the beginning for the Ultimate Exit feature set.

In this incident, a software bug caused a router to announce a large part of the IP address ranges present in the global routing table as if they were originated by AS7007. Two competing methodologies, RPSL and RPKI, are used to inform the defensive configuration of routers. We have made tremendous progress over the last decade.
