NFV’s Return on Investment Disappoints Some NFV Players
“We had inflated expectations” because the promise was vendors could easily obtain commodity hardware and “throw some VNFs on it and it would make money," said a Masergy executive.
Bandwidth Alliance: powered by smart routing on Cloudflare’s network
Today, we’re excited to announce the launch of the Bandwidth Alliance, a group of cloud providers that have agreed to reduce data transfer fees for mutual customers.
Three things were required to make the Bandwidth Alliance a reality:
- An ecosystem of like-minded companies who want to provide reduced data transfer fees to their customers.
- A large global and well-connected network (Cloudflare has 150+ points of presence around the world and multiple peered and paid links at each location). Our network is connected to thousands of partners through transit providers, Internet exchanges, peering interconnects, and private network interconnects. Having a large network footprint allows us to meet our partners where their infrastructure is and exchange traffic with them over low-cost or free connections, instead of expensive paid transit.
- Argo, our sophisticated traffic routing engine. Argo allows us to make decisions on how to carry traffic across our network in ways that optimize for a number of factors: latency, throughput, jitter, or in the case of the Bandwidth Alliance, cost to our partners to exchange traffic. This routing engine is the technical underpinning of the Bandwidth Alliance.
Typically, as traffic moves across the Internet, packets are exchanged between multiple networks as they Continue reading
Introducing the Bandwidth Alliance: sharing the benefits of interconnected networks
At Cloudflare, our mission is to help build a better Internet. That means making the Internet faster, safer and smarter, but also more efficient alongside our cloud partners. As such, wherever we can, we're on the lookout for ways to help save our common customers money. That got us looking into why and how much cloud customers pay for bandwidth.
If you're hosting on most cloud providers, data transfer charges, sometimes known as "bandwidth” or “egress” charges, can be an integral part of your bill. These fees cover the cost of delivering traffic from the cloud all the way to the consumer. However, if you’re using a CDN such as Cloudflare, the cost of data transfer comes in addition to the cost of content delivery.
In some cases, charging makes sense. If you're hosted in a facility in Ashburn, Virginia and someone visits your service from Sydney, Australia there are real costs to moving traffic between the two places. The cloud provider likely hands off traffic to a transit provider or uses its own global backbone to carry the traffic across the United States and then across the Pacific, potentially handing off to other transit providers along the way, until Continue reading

Infrastructure-as-Code Tools
This is the fourth blog post in “thinking out loud while preparing Network Infrastructure as Code presentation for the network automation course” series. Previous posts: Network-Infrastructure-as-Code Is Nothing New, Adjusting System State and NETCONF versus REST API.
Dmitri Kalintsev sent me a nice description on how some popular Infrastructure-as-Code (IaC) tools solve the challenges I described in The CRUD Hell section of Infrastructure-as-Code, NETCONF and REST API blog post:

It has been a trade-off between waiting long enough to have the key sentinel mechanism deployed in sufficient volume in resolvers to generate statistically valid outcomes and yet start this measurement prior to the planned roll of the KSK on 11th October 2018. These are early results, and reflect less than one week of measurement, but some strong signals are evident in the data.HPE Selects Intel Programmable Card for Data Center Servers

This information is extremely useful, allowing traffic analytics software to combine telemetry obtained from network devices with information obtained using the Microsoft REST API in order to identifying clients, links, and devices carrying the traffic, as well as any issues, such as link errors, and congestion, that may be impacting performance.
