As IPv6 gains more and more ground within the Internet we are starting to see recognition amongst the wider community that technologies such as Carrier Grade NAT (CGNAT) have some significant drawbacks from a service and scalability standpoint. Some of the issues were recently highlighted by a major carrier which actually issued a public “opt out” option to their customers if needed.

However, there are some applications such as online gaming, VPN access, FTP service, surveillance cameras, etc., that may not work when broadband service is provided via a CGN. For our customers utilizing these types of applications, we provide the ability to “opt out” of CGN Read More »

We first talked about the Mapping of Address and Port (MAP) method to handle IPv4 exhaust and the transition to IPv6 last week. MAP is based on two IETF drafts currently in the process of standardization in draft-ietf-softwire-map (MAP-E) and draft-ietf-softwire-map-t (MAP-T). The real advantage with MAP is that it’s stateless and doesn’t require additional hardware as traffic grows.   Read More »

There are a number of ways to deal with IPv4 exhaust and  IPv6 transition, including Carrier Grade NAT and stateful Dual Stack Lite. Cisco has added another method called Mapping of Address and Port (MAP) based on two IETF drafts currently in the process of standardization in draft-ietf-softwire-map (MAP-E) and draft-ietf-softwire-map-t (MAP-T). The real advantage with MAP is that it’s stateless and doesn’t require additional hardware as traffic grows. In fact, the MAP implementation on the Cisco ASR 1000 or ASR 9000 is just a software feature that can be enabled as needed. Read More »

Ever wondered who’s on a WebEx? Here’s a look at global activity that’s refreshed every few minutes.

Click in and take a look. You will see the host’s location and how many people are participating in the meeting. Some people are even in a one-person meeting, which I imagine means they are recording content to share with others or post on their website.

WebEx Makes the World a Little Smaller

What I find amazing is how many people are video conferencing from very remote locations -- really shows the power of the Internet and how it allows for collaboration no matter where you are!

If you use WebEx, you can see the power of the WebEx network. If you are hosting a WebEx event or have a recorded WebEx posted that’s public, let us know. Send us a tweet @WebExEvents and we’ll retweet your information to our network.

If you haven’t tried WebEx yet, you can get a free trial and download WebEx mobile free (you need an account if you want to host from a mobile; attending is free).
