This new Research Brief from AvidThink is aimed at providing enterprises and service providers with a view of the challenges in modern networking, and detailed strategies on how to overcome them by laying the right foundation for network automation.
We’ve had a lot going on behind the scenes at Network Collective. In this episode we give a little peak behind the curtain at what’s been going on with us and share some of the ways we’re modifying the show in response to how you all are consuming it.

The Internet Society participated in a Routing Security Workshop that was held during the Internet2 Technology Exchange 2018 on 15 October 2018 in Orlando, United States. The research and education networking community has been one of the key targets of the MANRS initiative that is promoting adoption of best practices to reduce threats to the global routing system, and this community workshop followed on from a previous engagement we had with Internet2 and a number of other R&E networks in the US earlier in the year.
Internet2 interconnects R&E institutes across the United States in conjunction with regional and state networks, so we see them as a key partner in raising awareness of the routing security issues, as well as encouraging the adoption of the four MANRS principles. Indeed, one of the aims of MANRS is for network operator communities to take ownership of this process by generating awareness and disseminating best practices, along with making recommendations for improvement. So this workshop was a fantastic step in this direction.
Another positive step was Internet2 formally becoming a MANRS participant shortly before the workshop, follow in the footsteps of ESnet, CAAREN, KanREN, George Washington University, Indiana University, and DePaul University. WiscNet Continue reading

Branch office traffic has changed due to the growing use of SaaS, video, and voice apps. Sites need flexible bandwidth, traffic segmentation, and load balancing. Multiple network links can help.
One of my readers sent me this question:
It would be nice to have a blog post or a webinar describing how to implement container networking in case when: (A) application does not tolerate NAT (telco, e.g. due to SCTP), (B) no DNS / FQDN, is used to find the peer element and (C) bandwidth requirements may be tough.
The only thing I could point him to is the Advanced Docker Networking part of Docker Networking Fundamentals webinar (available with free subscription) where macvlan and ipvlan are described.

Ah, unikernels. Small size, fast booting, tiny attack surface, resource efficient, hard to deploy on existing cloud platforms, and undebuggable in production. There’s no shortage of strong claims on both sides of the fence.
See for example:
In today’s paper choice, Williams et al. give us an intriguing new option in the design space: running unikernels as processes. Yes, that’s initially confusing to get your head around! That means you still have a full-fat OS underneath the process, and you don’t get to take advantage of the strong isolation afforded by VMs. But through a clever use of seccomp, unikernels as processes still have strong isolation as well as increased throughput, reduced startup time, and increased memory density. Most importantly though, with unikernels as processes we can reuse standard infrastructure and tools:
We believe that running unikernels as processes is an important step towards running them in production, because, as processes, they can Continue reading

EVPN is all the rage these days. The ability to do L2 extension and L3 isolation over a single IP fabric is a cornerstone to building the next-generation of private clouds. BGP extensions spelled out in RFC 7432 and the addition of VxLAN in IETF draft-ietf-bess-evpn-overlay established VxLAN as the datacenter overlay encapsulation and BGP as the control plane from VxLAN endpoint (VTEP) to VxLAN endpoint. Although RFC 7938 tells us how to use BGP in the data center, it doesn’t discuss how it would behave with BGP as an overlay as well. As a result, every vendor seems to have their own ideas about how we should build the “underlay” network to get from VTEP to VTEP, allowing BGP-EVPN to run over the top.
Let’s take a look at our options in routing protocols we could use as an underlay and understand their strengths and weaknesses that make them a good or bad fit for deployment in an EVPN network. We’ll go through IS-IS, OSPF, iBGP and eBGP. I won’t discuss EIGRP. Although it’s now an IETF standard, it’s still not widely supported Continue reading
Today, we’re excited to announce our solution for arguably the biggest issue affecting Accelerated Mobile Pages (AMP): the inability to use real origin URLs when serving AMP-cached content. To allow AMP caches to serve content under its origin URL, we implemented HTTP signed exchanges, which extend authenticity and integrity to content cached and served on behalf of a publisher. This logic lives on Cloudflare Workers, meaning that adding HTTP signed exchanges to your content is just a simple Workers application away. Publishers on Cloudflare can now take advantage of AMP performance and have AMP caches serve content with their origin URLs. We're thrilled to use Workers as a core component of this solution.
HTTP signed exchanges are a crucial component of the emerging Web Packaging standard, a set of protocols used to package websites for distribution through optimized delivery systems like Google AMP. This announcement comes just in time for Chrome Dev Summit 2018, where our colleague Rustam Lalkaka spoke about our efforts to advance the Web Packaging standard.
You may already see the need for Web Packaging on a daily basis. On your smartphone, perhaps you’ve searched for Christmas Continue reading
