IDG Contributor Network: What makes application delivery in China so hard?

At the end of 2016, China had over 700 million internet users, more than double the number of internet users in the U.S. And as the Chinese tech market continues to shift from hardware to software and services, Forrester Research analysts predict this will drive software growth of 10 percent over the next couple years.China is now a critical market for global technology companies and enterprises. It’s little wonder that tech giants like Apple, Facebook and others are clamoring to secure a hold there, even when it means addressing unique challenges and making certain compromises.To read this article in full or to leave a comment, please click here

Despite new silicon, 802.11ax isn’t coming to the enterprise for a while

The next great leap forward in Wi-Fi got a little closer to reality Tuesday with Broadcom’s announcement of a new family of chips designed to comply with the not-yet-finalized 802.11ax standard, but you might not need to game-plan for the arrival of 802.11ax products in the enterprise for quite awhile.However, thanks to several factors, including an unusual adoption cycle, the capabilities of existing Wi-Fi hardware and the standards process itself, 802.11ax is unlikely to take enterprise wireless customers by storm before late 2018, according to experts.+ ALSO ON NETWORK WORLD: Does MU-MIMO really expand Wi-Fi capacity? + 3 real-world examples of IoT rolled out in the enterprise + How Wi-Fi could get a boost from Li-FiTo read this article in full or to leave a comment, please click here

IPv6, Large UDP Packets and the DNS

It appears that rather than effecting a slight improvement from IPv4, the manner of fragmentation handling in IPv6 appears to be significantly worse than IPv4. Little wonder that there have been calls from time to time to completely dispense with packet fragmentation in IPv6, as the current situation with IPv6 appears to be worse than either no fragmentation or the IPv4-style of fragmentation.

Power outage hits the island of Taiwan. Here’s what we learned.

Power outage hits the island of Taiwan. Here’s what we learned.

At approximately 4:50pm local time (8:50am UTC) August 15, a major unexpected power outage hit the island of Taiwan with a significant amount of its power generation facilities going down.

Blackout!

Most of the island was hit with power outages, shortages and rolling blackouts, with street lights not functioning, nor power in many of Taipei’s shopping malls, and much other infrastructure.

Blackouts of this scale are very rare. Usually, during an outage of this scale, it would be expected that Internet traffic would greatly drop, as houses and businesses lose power and are unable to connect to the Internet. I’ve experienced this in the past, working at consumer ISPs. As households and businesses lose power, so do their modems or routers which connect them to the Internet.

However, during yesterday's outage, something different happened. I'd like to share some insights from yesterday's outage.

Even when the power is out, the Internet still operates

Most Telecom and Data Center facilities are built with redundancy in mind and have backup power generation. Our Data Center partner, Chief, was able to switch to backup power generation without any service interruption, allowing Continue reading

BrandPost: Going With Managed SD-WAN? Here’s How to Choose a Partner

SD-WAN is gaining tremendous traction among enterprises owing to the benefits it offers — cost savings from efficient use of low-cost Internet and wireless links, centralized control and management, network agility, speed to deployment of new sites, and optimized cloud connectivity—to list a few. And while a DIY model provides enterprise IT managers unprecedented flexibility and control over their WAN, a managed SD-WAN service may be better suited for businesses that prefer a turn-key service due to factors discussed in my previous blog.To read this article in full or to leave a comment, please click here

Worth Reading: The TCP Tortoise

As LinkedIn migrated to serving its pages on HTTP/2 earlier this year, it became imperative that we identify and use the most optimal transport layer strategy for our users’ network. Being a Transmission Control Protocol-centric (TCP) infrastructure, we initiated an effort to study the effects of different TCP congestion control strategies in different geographies. We found that with the right strategy, we could significantly improve our site speed, resulting in up to 7% faster content downloads. —Prasanna Vijayanathan @ Linkedin

The new Extreme Networks is off and rolling

The story of Extreme Networks is one of the more remarkable turnarounds I’ve seen in technology in years. About two years ago the company had a market cap of under $300 million, and I thought they were a sure-fire acquisition target for someone who wanted some decent technology on the cheap — because it was becoming apparently clear that the once-cool networking company had lost its way like so many others before it.Many of the brand names we have known in the past — Nortel, 3Com, Cabletron, Lucent, FORE systems and Foundry — all dropped as Cisco got bigger and HP Networking gobbled up the low end. There just didn’t seem to be room for another vendor. If an acquisition happened, it would likely fall on the scrap heap that so many other networking vendors have been tossed on.To read this article in full or to leave a comment, please click here
