DDoS attacks disrupt services and damage reputations, with motivations ranging from political to personal. These attacks can also mask more severe security breaches, so early detection and mitigation are crucial. Learn how Kentik provides a solution by analyzing enriched NetFlow data to identify and mitigate DDoS threats.
In the rapidly evolving telecom sector, the concept of “cloudification” is not just a trend but a transformative shift, reshaping how services are delivered and managed. This change is underpinned by modern software architectures featuring modularity, microservices, and cloud-native designs. As we embrace this new era, marked by the rise of “netcos” and “servcos,” we must also navigate the complexities it brings.
Learn how to analyze subscriber behavior using Kentik. In this post, we focus on the challenges and solutions of identifying and tracking the customers in an IP network while complying with regulations such as GDPR, show how Kentik Custom Dimensions and Data Explorer provide the analysis, and finally touch on how the associated APIs help automate and ease the entire process.
Broadband subscriber behavior analysis is the process of collecting and analyzing data on how broadband subscribers use the internet. This data can be used to gain insights into subscriber needs and preferences, as well as to identify potential problems with the broadband service.
By automating capacity planning for IP networks, we can achieve cost reduction, enhanced accuracy, and better scalability. This process requires us to collect data, build predictive models, define optimization objectives, design decision algorithms, and carry out consistent monitoring and adjustment. However, the initial investment is large and the result will still require human oversight.
Live sports have moved to the internet and are now streaming instead of being broadcast. Traditional streaming protocols have a built-in delay that challenges the experience of a live game. Amazon Prime has found a solution by combining a new protocol with a very distributed CDN.
This guide explores the benefits of embedded caching for ISPs and discusses deployment optimization strategies and future trends in CDN technology. Embedded CDNs help reduce network congestion, save costs, and improve user experiences. ISPs must carefully plan their deployment strategies by considering how each of the CDNs distributes content and directs end-users to the caches. They need to know both the CDNs and their network architecture in detail to build a successful solution.
Content delivery networks are an important part of the internet, as they ensure a short path between content and the consumers. The idea of placing CDN caches inside ISPs networks was created early in the days of CDNs. The number of CDNs with this offering is growing and ISPs all over the world take advantage of the idea. This post explains how this works and what to look out for to do it right.
Resiliency is a network’s ability to recover and maintain its performance despite failures or disruptions, and redundancy is the duplication of critical components or functions to ensure continuous operation in case of failure. But how do the two concepts interact? Is doubling up on capacity and devices always needed to keep the service levels up?
In this post, Nina Bargisen explores how peering coordinators can use combined NetFlow and BGP analysis tools to work around different capacity upgrades when money or delivery times pose a challenge.
