More regulation, please: Facebook CEO Mark Zuckerberg, in an op-ed in the Washington Post, called on governments to get more involved in Internet regulation, including defining harmful content and making rules on how sites should handle it. Governments should also look at new laws to protect elections, to improve consumer privacy, and to guarantee data portability, Zuckerberg said. His ideas weren’t universally embraced, however. The Electronic Frontier Foundation, in a blog post, said there were “fundamental problems” with governments policing harmful content, particularly in defining what’s harmful.
Hold my beer: Australia’s parliament didn’t take long to look at new regulations, with lawmakers passing legislation that would create three-year jail terms for social media executives and operators of other websites that do not remove violent content in an “expeditious” manner, NPR reports. Web-based services could also be fined up to 10 percent of their annual revenue for not complying with the law.
Even more laws: Singapore is the latest country to consider legislation attacking fake news. A proposed law there would require online news sites to publish corrections or warnings about stories the government decides are fake news and remove articles in extreme cases, the Straits Times reports.

Multicast is, at best, difficult to deploy in large scale networks—PIM sparse and BIDIR are both complex, adding large amounts of state to intermediate devices. In the worst case, there is no apparent way to deploy any existing version of PIM, such as large-scale spine and leaf networks (variations on the venerable Clos fabric). BEIR, described in RFC8279, aims to solve the per-device state of traditional multicast.
In this network, assume A has some packet that needs to be delivered to T, V, and X. A could generate three packets, each one addressed to one of the destinations—but replicating the packet at A is wastes network resources on the A->B link, at least. Using PIM, these three destinations could be placed in a multicast group (a multicast address can be created that describes T, V, and X as a single destination). After this, a reverse shortest path tree can be calculated from each of the destinations in the group towards the source, A, and the correct forwarding state (the outgoing interface list) be installed at each of the routers in the network (or at least along the correct paths). This, however, adds a lot of state to the network.

APIC Controller Cluster You actually need three APIC controller servers to get the cluster up and running in complete and redundant ACI system. You can actually work with only two APICs and you will still have a cluster quorum and will be able to change ACI Fabric configuration. Loosing One Site In the MultiPod, those three controllers need to be distributed so that one of them is placed in the secondary site. The idea is that you still have a chance to keep your configuration on one remaining APIC while losing completely primary site with two APICs. On the other

Last Thursday I started another experiment: a series of live webinar sessions focused on business aspects of networking technologies. The first session expanded on the idea of three paths of enterprise IT. It covered the commoditization of IT and networking in particular, vendor landscape, various attempts at segmenting customers, and potential long-term Enterprise IT paths. Recording is already online and currently available with standard subscription.
Although the attendance was lower than usual, attendees thoroughly enjoyed it – one of them sent me this: “the value of ipSpace.net is that you cut through the BS”. Mission accomplished ;)
50 years ago today, on 7 April 1969, the very first “Request for Comments” (RFC) document was published. Titled simply “Host Software”, RFC 1 was written by Steve Crocker to document how packets would be sent from computer to computer in what was then the very early ARPANET. [1]
Steve and the other early authors were just circulating ideas and trying to figure out how to connect the different devices and systems of the early networks that would evolve into the massive network of networks we now call the Internet. They were not trying to create formal standards – they were just writing specifications that would help them be able to connect their computers. Little did they know then that the system they developed would come to later define the standards used to build the Internet.
Today there are over 8,500 RFCs whose publication is managed through a formal process by the RFC Editor team. The Internet Engineering Task Force (IETF) is responsible for the vast majority (but not all) of the RFCs – and there is strong process through which documents move within the IETF from ideas (“Internet-Drafts” or “I-Ds”) into published standards or informational documents[2].
