Resilience and Redundancy in Networking

Kentik

This includes the ability to: Dynamically adjust to changes in network topology Detect and respond to outages Route around faults in order to maintain connectivity and service levels. While redundancy is a significant contributor to network resilience, other mechanisms, protocols, and methods can also contribute to overall network resilience.

Securing Your Network Against Attacks: Prevent, Detect, and Mitigate Cyberthreats

Kentik

Cyberthreat strategies have evolved in step with modern cloud networks, often using cheap, virtualized cloud resources to exploit the threat surface topology I briefly described above. Protocol-based. These attacks overwhelm network infrastructure resources, targeting layer 3 and layer 4 communication protocols.

Why latency is the new outage

Kentik

After the DNS lookup and the ARP, the host reaches out to the IP address of the destination using a SYN in order to open a connection. I was looking for a command line ping utility that used the Quic UDP protocol against websites. Here we will explore how latency can be measured and the factors that can introduce latency.

Practical Steps for Enhancing Reliability in Cloud Networks - Part I

Kentik

Network reliability engineers (NREs) The scale, transient nature of resources and topology, and extensive network boundaries make delivering on network reliability a complex and specialized task. Additionally, monitoring becomes critical for network optimizations by identifying areas where resources are under or overutilized.

Speeding Up the Web: A Comprehensive Guide to Content Delivery Networks and Embedded Caching

Kentik

Well, that depends on the network topology of the network but also on which CDN and how that CDN maps the end users to a cluster. They heavily rely on BGP (Border Gateway Protocol, the protocol that networks use to exchange routes) to define which cache an end user is directed to. Where is site.com ? Where is site.com ?

A Brief History of the Internet’s Biggest BGP Incidents

Kentik

Large-scale origination leaks like these have become less frequent in recent years due to increases in the automation of router configuration in topologically-central networks. In 2018, attackers employed a BGP hijack that redirected traffic to Amazon’s authoritative DNS service.
