We have a block of static IPs facing the public, and have to have a router which points all the traffic to our router/gateway which points all the traffic to the ISP. Right now, all traffic has a static rule to send all traffic to the ISP gateway on the router at the edge going to the hand off. network subnet 10.113.0.0
As a result, Internet devices usually use a single path and let the routers handle the path selection. Aggregation : MPTCP can aggregate the bandwidth of many network interfaces. Mobility : On a customer device, a TCP stream is typically broken if the underlying network interface goes away. There is another way.

Enterprises migrate to multi-cloud networks not because they want to, but because they have to. Two exciting new capabilities help you quickly answer any question about your multi-cloud network: Kentik Cloud users can now collect, analyze, and visualize flow logs generated on AWS Transit Gateways. There’s an acquisition.
But, we also learned something else: When there is a network problem, we have to figure it out ourselves, which is less awesome. Leading up to SaaS offerings, everything we communicated with over the network to do our jobs (other than surf the web and send email) was hosted on-premises. I mean, no one sees me from the waist down.”.
When more of the workforce shifts to working remotely, it puts new and different strains on the infrastructure across different parts of the network, especially where VPN gateways connect to the network edge. Kentik provides an easy way to see not only the entire network but also how it’s being used.
Understanding the network footprint of applications and services is now essential for delivering fast and reliable services in cloud-native environments.

For reasons of enforced obfuscation by RFC writers, routes are also called Network Layer Reachability Information (NLRI). Another foundational concept is the Autonomous System (AS), which is a way of referring to a network. That network could be yours, or belong to any other enterprise, service provider, or nerd with her own network.
The networking industry loves a good buzzword as much as any other IT sector. Network-as-a-Service (NaaS) certainly fits that billing. The term has been around for at least a decade has come back in vogue to describe networking purchased on a subscription basis. Gartner identifies the specific attributes of a cloud service.
On May 27 of this year, Gartner Research Director Sanjit Ganguli released a research note titled “Network Performance Monitoring Tools Leave Gaps in Cloud Monitoring.” You’d put a few others — I emphasize “few” because these appliances were and are not cheap — at other major choke points in and out of the network.
We really respected their thoroughness and the fact that they are practicing network engineers, so as we’ve come up with cool new gizmos in our product, we’ve asked them to extend their review. Following here, from their latest review, are some excerpts that focus on Kentik NPM, our enhanced network performance monitoring solution.
Flow-based network monitoring relies on collecting information about packet flows (i.e. a sequence of related packets) as they traverse routers, switches, load balancers, ADCs, network visibility switches, and other devices. Flow-based monitoring provides significant advantages over other network monitoring methods.
Making Flow Records a Force for Good on Your Network. In fact, the network infrastructure of nearly every business that uses IP networks — which these days is effectively everyone — generates volumes of metadata on an hourly basis. Network metadata has been available for a relatively long time. Analysis (R)evolution.
Instead of simply porting our mobile social apps, we chose React Native as it enabled our teams to iterate and build quickly with robust animation capabilities, great performance, and a shared platform that powers most of the 2D Meta Quest system apps. The most impactful improvement that our teams made was initiating network queries earlier.
This is where infrastructure visibility paired with network traffic analysis can save the customer experience. Using a network monitoring tool that focuses on infrastructure devices, you can easily identify bandwidth bottlenecks. Combining network details with flow analytics gets you answers for your client. They get it.
We were one of SprintLink’s first BGP customers, and we had dozens of Cisco and Wellfleet routers. What we didn’t have was a way to answer any of the many urgent network utilization questions we faced every day: Where was our users’ traffic was coming from? Where should it plug into the network? Should it be a DS3?
