Fight for net neutrality rules gains momentum

The U.S. Supreme Court has officially ended the court fight over the repealed net neutrality rules that required internet providers to treat all online traffic equally.On Nov. 5, 2018, the court rejected appeals from the telecommunications industry seeking to throw out a lower court ruling in favor of the net neutrality rules. The Federal Communications Commission (FCC) under President Donald Trump has rolled back the rules, but the industry also wanted to completely remove the lower court’s ruling off the books.The Supreme Court's decision is a victory for advocates of net neutrality rules, as supporters hope this will push Congress to enact new net neutrality laws or encourage other states to follow California’s lead by instituting their own requirements.To read this article in full, please click here

Tariffs on China cause new data center equipment prices to increase

As if the end of the year doesn’t present enough challenges for IT professionals, now there is the added concern coming from the Trump administration regarding the tariffs that were imposed on China back on Sept. 24.Companies including Cisco, Dell, HPE, and Juniper Networks all called for networking and server equipment to be dropped from the tariff regulations, but they were unable to persuade the U.S. government to do that.“By raising the cost of networking products, the proposed duties would impede the development and adoption of cloud-based services and infrastructure,” the group told trade regulators before the tariff was imposed, according to Reuters.To read this article in full, please click here

What’s hot in network certifications

Network certifications typically serve as a litmus test of a network professional’s knowledge of technologies that most company already use. Increasingly, however, network professionals are looking beyond what is, and they’re getting a leg up on certifications that will set them apart from their peers in the near future.To read this article in full, please click here(Insider Story)

Juniper RADIUS-delivered switching filters

I’ve been experimenting with getting RADIUS to deploy switching filters to Juniper switches recently, as part of a reference architecture demo.  The concept is called REACH2020 and combines network virtualisation with the ability to identify network users and devices so that categories of user can be put into different virtual networks.   This leaves the firewall that connects the virtual networks together as a convenient single point of control.

Anyway, back to the matter in hand.  It turns out there’s a limit to the length of switching filter you can send a Juniper EX.

In this case, I am using Aruba Clearpass 6.6 to send some RADIUS attributes to a Juniper EX4300 switch using Junos 17.4.     What I need to do is send a web portal address that a connecting client will be redirected to, and a switching filter so that they can’t go anywhere other than the portal. The switching filter is required as far as I can tell – if you just send the portal address, Junos ignores the RADIUS attribute.

An alternative way of achieving this is to configure your centralised web authentication (CWA) web portal on every edge switch, but since RADIUS Continue reading

IETF 103, Day 2: IPv6, NTP, Routing Security & IoT

This week is IETF 103 in Bangkok, Thailand, and we’re bringing you daily blog posts highlighting the topics of interest to us in the ISOC Internet Technology Team. And following on from the previous day, Tuesday also features a packed agenda.

LPWAN will be discussing whether to move to a Working Group Last Call on the Static Context Header Compression (SCHC) framework for IPv6 and UDP, that provides both header compression and fragmentation functionalities. Three other drafts describe similar schemes for SigFox,LoRaWAN and IEEE 802.15.4 type networks.

NOTE: If you are unable to attend IETF 103 in person, there are multiple ways to participate remotely.

Then at 11.20 UTC+7, IPWAVE will be focusing on updates to the specification for transmitting IPv6 Packets over IEEE 802.11 Networks in Vehicular communications, and the use cases for IP-based vehicular networks. There have also been a couple of updates to DNS Name Autoconfiguration for Internet of Things Devices and IPv6 Neighbor Discovery for Prefix and Service Discovery in Vehicular Networks, so these may also be discussed.

6MAN will be meeting at 13.50 UTC+7 and has nine drafts up for discussion. The couple of working group Continue reading
