It allows network administrators to centrally manage network switches, routers, wireless access points, printers, network-attached storage systems, firewall appliances and other devices that support SNMP (Simple Network Management Protocol).The software is free for managing up to 200 devices and provides an easy-to-use Web graphical interface that can be accessed remotely.To read this article in full or to leave a comment, please click here

Cisco-Jasper deal should make enterprise IoT safer

Cisco Systems' planned US$1.4 billion acquisition of Jasper Technologies could make it easier for enterprises to build businesses around services instead of products. While the Internet of Things includes sensors and devices that enterprises can use to better run their operations and cut costs, it can also give them whole new business models. Much of Jasper's business is connecting the products companies make to mobile networks. It sits between enterprises and mobile operators, doing the complicated work of tying IoT applications to network connections. Cisco builds a lot of the gear on the network side of that equation, plus higher-level smarts like analytics on the other end that can make IoT more effective and profitable. Bringing their capabilities together will simplify deployments that currently involve lots of different companies and pieces of software, the companies say.To read this article in full or to leave a comment, please click here

As 5G approaches, 3G and 4G are still getting faster

Most of the excitement at Mobile World Congress this month will be about 5G, which won't officially exist until 2020. But vendors will also be showing off new ways to speed up the networks people are using now.That means more than 4G, because while LTE gets a lot of press, older services are more common than you might think. Just over half of the world's mobile subscriptions (51 percent) are for 2G service only, according to Tolaga Research analyst Phil Marshall. Almost one-third are limited to 3G, while only 15 percent are 4G. Even in 2020, only 48 percent of subscriptions will be for 4G.Some users are stuck on a slower network because they haven't upgraded to a faster phone, and some of those 2G-only subscriptions are for connected machines that don't need any more speed. But there are a lot of mobile users who could use a performance bump even before 5G comes along.To read this article in full or to leave a comment, please click here

Arista just lost a patent round against Cisco and could face an import ban

Cisco Systems has won the latest round against Arista Networks at a U.S. trade agency that could block importation of Arista products. Arista violated three Cisco patents on networking technologies, Administrative Law Judge David Shaw of the U.S. International Trade Commission ruled on Tuesday. If the full Commission confirms that finding, the ruling could be bad news for Arista, a growing player in data-center networking.MORE ON NETWORK WORLD: 15 more useful Cisco sites Cisco sued Arista in December 2014, alleging the Silicon Valley startup violated 14 patents in its Arista EOS operating system. The legal battle continues, heading toward two possible trials in federal court as well as continuing activity at the ITC. In a blog post Tuesday, Cisco General Counsel Mark Chandler said a ruling in a second ITC investigation is expected in April.To read this article in full or to leave a comment, please click here

Comcast targets first markets it will offer gigabit over copper cable service

Comcast announced today that Atlanta and Nashville would be its first two markets to offer DOCSIS 3.1 technology, in “early 2016,” and that Chicago, Detroit and Miami would join them in the second half of the year.DOCSIS 3.1 is a new wired cable Internet standard, which gives Comcast the ability to offer gigabit speeds over existing copper cable. The latest version of the standard uses smaller subcarrier channels that use considerably less bandwidth than those of DOCSIS 3.0, bonding those subchannels together for greater efficiency. The company said that it tested the technology last month in its home market of Philadelphia.+ALSO ON NETWORK WORLD: 'Big bets' cost Google parent Alphabet $3.6 billion in losses last year + Microsoft starts recommended update roll-out for Windows 10To read this article in full or to leave a comment, please click here

Law professor: T-Mobile’s Binge On program violates Net neutrality

A T-Mobile service called Binge On that allows subscribers to consume as much data as they want while streaming video from selected providers violates Net neutrality rules, according to a published analysis from Stanford University legal scholar Barbara van Schewick.Net neutrality’s core tenet is that service providers shouldn’t be allowed to discriminate between different types of traffic they’re asked to carry. By offering some video services – including Netflix, Hulu and HBO – and not others as “free” streaming options, and not counting mobile data consumed from those services toward a user’s monthly cap, T-Mobile is essentially favoring some kinds of video content over others, van Schewick wrote.To read this article in full or to leave a comment, please click here

Forget about LTE hurting Wi-Fi and think about using it in your business

Controversial technology that lets LTE networks use unlicensed spectrum could become a trusted part of the enterprise IT toolkit in a few years.So-called unlicensed LTE has come under fire ever since the news about it first broke more than a year ago. The charge: If mobile operators adapt their LTE networks to use frequencies that Wi-Fi depends on, Wi-Fi users will get squeezed out.ALSO ON NETWORK WORLD U.S. carriers stay tight-lipped on LTE-U deployments The two sides are now working together on standard tests to tell if a given unlicensed LTE radio unfairly interferes with Wi-Fi. Meanwhile, Qualcomm, the biggest cheerleader for the new technology, just got permission to try it out at Verizon Wireless facilities in Oklahoma City and Raleigh, North Carolina, the Federal Communications Commission said Friday. The industry group Wi-Fi Forward promptly declared the FCC should closely monitor the experiments.To read this article in full or to leave a comment, please click here

Cisco patches authentication, denial-of-service, NTP flaws in many products

Cisco Systems has released a new batch of security patches this week for flaws affecting a wide range of products, including for a critical vulnerability in its RV220W wireless network security firewalls.The RV220W vulnerability stems from insufficient input validation of HTTP requests sent to the firewall's Web-based management interface. This could allow remote unauthenticated attackers to send HTTP requests with SQL code in their headers that would bypass the authentication on the targeted devices and give attackers administrative privileges.Cisco has patched this vulnerability in the 1.0.7.2 firmware version for RV220W devices. Manual workarounds include disabling the remote management functionality or restricting it to specific IP addresses.To read this article in full or to leave a comment, please click here

Inside Verizon’s Super Bowl Control Center

With banks of big-screens high along three walls and a huge TV on the fourth, it could be a great spot to watch The Super Bowl. But when the Denver Broncos take on the Carolina Panthers on Feb. 7, the people in this room won't be concerned with touchdowns, running yards and time outs. They'll be analyzing gigabits, latency and capacity to make sure Verizon's cellular network holds up for fans.This is Verizon's Super Bowl command room -- a temporary, purpose-built nerve center in the shadow of Levi's Stadium that pulls in data from permanent and temporary base stations near the site of Super Bowl 50 and the fan area in downtown San Francisco.Organizers predict up to a million people will visit the Bay Area for The Super Bowl, so Verizon has added 46 small cells and 10 macro cells to augment its network.To read this article in full or to leave a comment, please click here

Asentinel reduces costs and improves the efficiency of mobile device service contracts  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  If I brought up the term "mobility management" you'd probably think I was talking about BYOD and managing how workers can securely access applications and data via their smart phones. That's the aspect of mobility that IT usually has to deal with. But there's also an administrative aspect to mobility management that can be a real pain – and a big expense – for companies if it's not done well.I'm referring to the contract management aspect of company-provided mobile devices. Companies that pay for their employees' device contracts through expense reports are missing an opportunity to reduce administrative hassles and save quite a bit of money.To read this article in full or to leave a comment, please click here

U.S. carriers stay tight-lipped on LTE-U deployments

America’s big four wireless service providers are enthusiastic about the prospect of delivering data over unlicensed frequencies via LTE-U, but they’re playing their cards very close to their chests when it comes to specific plans.LTE-U, which is a wireless protocol designed to let carriers use their LTE signals over the same unlicensed frequencies as Wi-Fi, is a controversial technology. Advocates, which include the wireless carriers, insist that coexistence features built into the standard will allow it to use the same airwaves as Wi-Fi without interference. Critics say that independent testing shows that LTE-U could drown out Wi-Fi signals when the two conflict.To read this article in full or to leave a comment, please click here

U.S. Congress to federal agencies: You have two weeks to tally your backdoored Juniper kit

Around two dozen U.S. government departments and federal agencies are being questioned by the U.S. Congress on whether they were using backdoored Juniper network security appliances. In December, Juniper Networks announced that it had discovered unauthorized code added to ScreenOS, the operating system that runs on its NetScreen network firewalls. The rogue code, which remained undetected for 2 years or more, could have allowed remote attackers to gain administrative access to the vulnerable devices or to decrypt VPN connections. The U.S. House of Representatives' Committee on Oversight and Government Reform wants to determine the impact that this issue had on government organizations and how the affected organizations responded to the incident.To read this article in full or to leave a comment, please click here
