Re: Comcast is using Sandvine to manage P2P Connections

said by funchords:

WHERE: On the boundaries, at the point where Comcast connects to other points of the Internet,
I'm going to have to modify this, as I'm now seeing RSTs being forged on paths that never leave Comcast.net space.

Comcast techies -- can you help me understand why? Also, is there a decoder ring for the prefixes "GE," "TE," "PO," and etc.?

ge = gigabit ethernet.

te = ten gigabit ethernet.

p, po, pos = Packet Over Sonet (an OC-3 or faster connection).

1-1, 1-2, 1-11, 6-1, 9-1, 2-2, etc. = slot and port.

ar01, cr01, ur01 = probably a router name ?

:

Judging by the location of these names - 'cr' appearing on everything with a 'cbone' hostname for example - it would appear that these are as follows: 'cr' is a core router, or a backbone router. 'ar' would be an access router, something in a local metro region. 'ur' could be a user router, or perhaps more likely it is named after the uBR router series from Cisco (uBR means universal Broadband Router) widely used in cable internet operations.
