A networking engineer attending the Building Next-Generation Data Centers online course sent me this question:
My client will migrate their data center, so they’re not interested in upgrading existing $vendor load balancers. Would HAProxy be a good alternative?
As you might be facing a similar challenge, here’s what I told him:

See also: http://graphit-lang.org/.
The problem with finding the optimal algorithm and data structures for a given problem is that so often it depends. This is especially true when it comes to graph algorithms.
It is difficult to implement high-performance graph algorithms. The performance bottlenecks of these algorithms depend not only on the algorithm and the underlying hardware, but also on the size and structure of the graph. As a result, different algorithms running on the same machine, or even the same algorithm running with different types of graph on the same machine, can exhibit different performance bottlenecks.
What we’d like therefore, is some way of expressing a graph algorithm at a high level such that we can map it into different implementations, each applying different optimisations as needed. For bonus points, we could then automate the search within the optimisation space to find the best performing combination for the circumstances at hand.
This is exactly what GraphIt does. GraphIt combines a DSL for specifying graph algorithms with a separate scheduling language that determines implementation policy. You can specify a schedule yourself, or use autotuning to discover optimal schedules for Continue reading
R1 and R2 are cabled up twice to each other via their gig0/0/1 interfaces and their gig0/0/7 interfaces. Each connection is in its own subnet, and each interface configured for OSPF and MPLS. But while we have 2 OSPF neighbors between them… we only have 1 LDP neighbor.
R1#show mpls int
Interface IP Tunnel BGP Static Operational
Gi0/0/1 Yes (ldp) No No No Yes
Gi0/0/7 Yes (ldp) No No No Yes
R1#
So as you can see from the output of show mpls interface, gig0/0/1 and gig0/0/7 are both configured for MPLS LDP. Why then if we look below do we see only 1 MPLS LDP neighbor between them?
What is the problem? Actually… in this situation there isn’t a problem. This is actually expected behavior.

Let’s pretend I own a service and I want to grant other services access to my service on behalf of my users. The familiar OAuth 2.0 is the industry standard used by the likes of Google sign in, Facebook, etc. to communicate safely without inconveniencing users.
Implementing an OAuth Authentication server is conceptually simple but a pain in practice. We can leverage the power of Cloudflare Worker to simplify the implementation, reduce latency, and segregate our service logic from the authentication layer.
For those unfamiliar with OAuth, I highly recommend reading a more in depth article.
The steps of the OAuth 2.0 workflow are as follows:
Adding these policy-based security capabilities to the Pivot3 Intelligence Engine enables customers to integrate data encryption and key management into the same workflow for managing applications and storage.
Etcd is the primary storage location for Kubernetes and needs to be established before Kubernetes can be run on a system.
The main reason that blockchain can be considered for IoT security and privacy is that blockchain has built-in data protection and security mechanisms.
Data center interconnect equipment revenue will increase 85 percent over the next five years, from $2.7 billion in 2017 to $5.1 billion in 2022, according to Dell’Oro Group.
Amid all the political noise, Huawei ploughs on regardless with a further advance in 5G network slicing and a new 5G network deal with Altice Portugal.
The collaboration focuses on the three biggest container pain areas for enterprises: 1) networking; 2) visibility; and 3) security.
Connecting the most remote and challenging territories of any country to the Internet can be tough. Typically, Internet access spreads gradually from urban conglomerations towards smaller hubs, and finally, to the most remote and sparsely populated areas. This is just common business sense.
Many of these remote areas are unique in terms of their people, culture, and livelihood, and Internet access can make a world of difference. This was the case when the Internet Society, together with its local partners, launched the first community network in Georgia, in the mountainous region of Tusheti, in September 2017.
Creating Impact
One year on, the Internet has made a significant difference to the lives of the Tushetians. This week, the Internet Society published an impact assessment on the Tusheti community network highlighting the transformation in tourism, e-commerce, and people’s livelihoods.
The Internet has had a positive impact on tourism through more effective online advertising and sales, and through efficiencies in businesses operations. With these encouraging developments, local residents are investing in the construction and opening of new guesthouses. The Internet has also increased the levels of safety and mobility in this remote part of the world by providing a communications channel to Continue reading
