U.S. SEC Targets Unregulated Cryptocurrency Exchanges

The U.S. Securities and Exchange Commission could soon crack down on unregulated cryptocurrency trading platforms after the agency sent a strongly worded warning to them this week.

The SEC warned that unregulated online trading platforms may be misleading investors by calling themselves “exchanges,” which implies federal oversight. An SEC-related securities exchange, among other safeguards, has rules designed to prevent fraud and other manipulative practices, the SEC said in an advisory issued Wednesday.

The SEC advisory served as much as a warning to investors using cryptocurrency trading platforms as to the platforms themselves.

“The SEC staff has concerns that many online trading platforms appear to investors as SEC-registered and regulated marketplaces when they are not,” the advisory said. “Many platforms refer to themselves as ‘exchanges,’ which can give the misimpression to investors that they are regulated or meet the regulatory standards of a national securities exchange.”

The SEC does not review the trading protocols used by unregulated trading platforms, it said. “Although some of these platforms claim to use strict standards to pick only high-quality digital assets to trade, the SEC does not review these standards or the digital assets that the platforms select, and the so-called standards should Continue reading

Network Refresh: Why You Need a Second Opinion

How to check your network connections on Linux

The ip command has a lot to tell you about the configuration and state of your network connections, but what do all those words and numbers mean? Let’s take a deep dive in and see what all the displayed values are trying to tell you.When you use the ip a (or ip addr) command to get information on all the network interfaces on your system, you're going to see something like this:$ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp0s25: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:1e:4f:c8:43:fc brd ff:ff:ff:ff:ff:ff inet 192.168.0.24/24 brd 192.168.0.255 scope global dynamic enp0s25 valid_lft 57295sec preferred_lft 57295sec inet6 fe80::2c8e:1de0:a862:14fd/64 scope link valid_lft forever preferred_lft forever The two interfaces on this system — the loopback (lo) and network (enp0s25) — are displayed along with a lot of stats. The "lo" interface is clearly the loopback. We can see the loopback IPv4 address (127.0.0.1) and the loopback Continue reading

Ansible for Extreme Devices

Here’s something I’ve been working on recently: Ansible modules for Extreme SLX switches & routers. Ansible is a popular automation framework, and with good reason: it has a low barrier to entry. Time to usefulness is short. But you need device-specific modules to work with networking devices. Finally we have some modules for SLX. Read on for how to use them.

This blog is not an intro to Ansible in general. There’s plenty of good intros out there. This is specifically about demonstrating Ansible with SLX switches.

Background

Ansible is an agent-less configuration management system. It uses “playbooks”, written in YAML, to define desired configuration state. “modules” written in Python translate this into whatever is needed to configure the system, application, database or network device.

Ansible has been making great strides in adding network automation capabilities. But we haven’t had any modules for working with ~Brocade~ Extreme devices. That is now changing.

PaulQuack has contributed MLXe (Ironware) modules, which will go GA in Ansible 2.5 (due for release in March 2018). And I’ve been working on modules for the SLX, with my colleagues. These have not yet been merged upstream, but it’s Open Source, so you can grab Continue reading

IDG Contributor Network: The delivery challenges every SD-WAN project must consider

It’s no secret that enterprises are looking at SD-WAN as the means for evolving their networks. The technology improves on MPLS with better agility, more capacity increased resiliency and, of course, cost savings. Those advantages are in much need; just ask anyone who’s runs an MPLS network. They’ll tell you about its high costs, long provisioning times, and susceptibility to last-mile failures.But keep listening and MPLS customers are also bound to talk about the technology’s rock-solid reliability. They’ll hate the price and delays, but they’ll love their SLA-backed performance and how the MPLS provider takes care of everything — the last mile connectivity, managing the backbone, consolidated billing and more.To read this article in full, please click here

IDG Contributor Network: How edge computing makes voice assistants faster and more powerful

Voice is becoming a pervasive way to manage and interact with everyday tech devices, going from initial adoption in phones and smart speakers toward smartwatches, cars, laptops, home appliances and much more.Cloud platforms take most of the praise for enabling voice assistant services such as Amazon Alexa, Google Assistant or Microsoft Cortana – neglecting due credit to the increasing role that edge computing plays in enabling voice interfaces. A substantial amount of processing and analysis occur on devices themselves to allow users to interface with them by simply talking.Keyword detection Voice-enabled devices are not constantly recording audio and sending it to the cloud to determine if someone is giving them an instruction. That would not only be a privacy concern, but also a waste of energy, computing and network resources. Having to send all words to the cloud and back also introduces latency and slows the responsiveness of the system. Today’s voice interfaces typically use keyword or “wake-word” detection, dedicating a small portion of edge computing resources (i.e. computing done on the device itself or “at the edge”) to process microphone signals while the rest of the system remains idle. This is a power-efficient approach particularly important Continue reading

Marvell revs up Ethernet to 400Gbps with new ‘Alaska’ chips

Marvell Semiconductor is the first semiconductor to ship networking chips supporting the 802.3cd standard that will pump up Ethernet ports to 400Gbps max.The 802.3cd standard is designed to eventually replace the current physical Ethernet ports, which run at 25Gbps to 100Gpbs, with ports that will run at 50Gbps, 200Gbps, and 400Gbps.And Marvell is the first chip vendor out of the gate with support for the standard in its Alaska C 88X7120 transceivers. The chips aren’t fully cooked, but they are sampling to customers. Sampling is to semiconductors what beta testing is to software.To read this article in full, please click here
