I’ve got some important news which I will reveal in the beginning of December!
So stay tuned
If you work in the voice or video world, you’ve undoubtedly heard about Mean Opinion Scores (MOS). MOS is a rough way of ranking the quality of the sound on a call. It’s widely used to determine the over experience for the user on the other end of the phone. MOS represents something important in the grand scheme of communications. However, MOS is quickly becoming a crutch that needs some explanation.
The first think to keep in mind when you look at MOS data is that the second word in the term is opinion. Originally, MOS was derived by having selected people listen to calls and rank them on a scale of 1 (I can’t hear you) to 5 (We’re sitting next to each other). The idea was to see if listeners could distinguish when certain aspects of the call were changed, such as pathing or exchange equipment. It was an all-or-nothing ranking. Good calls got a 4 or even rarely a 5. Most terrible calls got 2 or 3. You take the average of all your subjects and that gives your the overall MOS for your system.
When digital systems came along, MOS took Continue reading
The oft-requested and long awaited arrival of TACACS+ support in Cisco’s Identity Services Engine (ISE) is finally here starting in version 2.0. I’ve been able to play with this feature in the lab and wanted to blog about it so that existing ISE and ACS (Cisco’s Access Control Server, the long-time defacto TACACS+ server) users know what to expect.
Below are five facts about how TACACS+ works in ISE 2.0.
CloudFlare launched just five years ago with the goal of building a better Internet. That’s why we are excited to announce that beginning today, anyone on CloudFlare can secure their traffic with DNSSEC in just one simple step.
This follows one year after we made SSL available for free, and in one week, more than doubled the size of the encrypted web. Today we will do the same with DNSSEC, and this year, we’ll double the size of the DNSSEC-enabled web, bringing DNSSEC to millions of websites, for free.
If DNS is the phone book of the Internet, DNSSEC is the unspoofable caller ID. DNSSEC ensures that a website’s traffic is safely directed to the correct servers, so that a connection to a website is not intercepted by a man-in-the-middle.
Every website visit begins with a DNS query. When I visit cloudflare.com, my browser first needs to find the IP address:
cloudflare.com. 272 IN A 198.41.215.163
When DNS was invented in 1983, the Internet was used by only a handful of professors and researchers, and no one imagined that there could be foul play. Thus, DNS relies on Continue reading
Decoupling like Juniper? No comparison, say Versa's founders.
Andrew Lerner, my favorite Gartner analyst, recently published a hilarious blog post describing what vendors mean when they say “our product is software-defined” or “we’ll make it work”. Enjoy!
Need more vendorspeak? Try eight levels of vendor acceptance (carefully documented during a particularly stressful on-site test in Poland).
Ericsson and Cisco worked on this relationship for more than a year.

Whatever it is, the Cisco/Ericsson alliance will threaten competitors.
