I just recently caught up with a presentation that was given earlier this year at Shmoocon 2009 schmoocon This happened back in February.
One of the key things they pointed out is the change in trust model. It changes the trust from being the customer locations to including the whole Network between the customer locations. While that is true, they are neglecting to mention the “P” part of VPLS. Private. With Carrier Ethernet specifically the technology I’m usually talking about VPLS, there is private separation of one customers traffic with another customers traffic. While the trust model does change, I’m not so sure it’s a whole lot different than the trust model of a standard TDM T1. Read more... (955 words, 1 image, estimated 3:49 mins reading time)
They are calling this offering VPLS
It looks like they are allowing either Point to Point or Point to Multi-point for their EVC connections, or full meshing for the multipoint to multipoint network, these “network connections are across 29 points of presence in 12 countries across the globe.”
Telstra’s press release
The CEO says the company is hurting for 2010, to me it looks like they are resting a lot of their next year revenue on their VPLS offering. The large enterprise customers are “booming” for Ethernet because it lets the customer control more of their network Read more... (540 words, estimated 2:10 mins reading time)
So, I’ve been doing this for around 4 months. I’ve had a few comments, but mostly what I see is indifference or not really getting any traction. I’d like to see a few more people get involved either to make it more interesting or to get some conversation / debate going on different topics. A healthy debate is always interesting.
I’m looking for anybody who is fairly technical and competent. I’m not going to allow anybody who is trying to gather research or allow anybody who is trying to promote their own company or their own service / product. Read more... (188 words, estimated 45 secs reading time)

I had the opportunity to spend a day talking with one of our largest customers. Sales flew me out of phoenix, 3 hours early in the morning at 4am, and flew me back late at night getting home around 11pm. All in all it was a REALLY long day. The opportunity was to try to get them as a beta customer, but I ended up learning quite a bit about marketing VPLS and Ethernet. while over the Grand Canyon and talking to the guy seated next to me and he was visibly impressed I was going for just the day. It was a breeze going through security with only a laptop bag. Read more... (1029 words, estimated 4:07 mins reading time)
VPLS uses a mechanism called split horizon forwarding. Split horizon forwarding is basically A rule that prohibits a PE from learning about MAC addresses from the direction it came from. So for example, if a PE receives an unknown MAC from a CE it must flood that frame to all the other PEs participating in the customers VPLS. However if the PE receives a frame from another PE is must send that frame to the CE, but MUST NOT send that frame to any other PE. Read more... (148 words, estimated 36 secs reading time)
