Re: Google not symmetric?

said by xenophon:


With this architecture, the network of Google not only provides 1 Gbps to each user, but this is symmetrical, which would be impossible in a GPON deployment, having to share all the users upload rate up to 1, 25 Gbps

Actually 1 Gbps symmetrical is possible with a GPON (2.5 Gbps / 1.25 Gbps theoretical) deployment but it might be seriously oversubscribed if 32 customers sharing the same optical fiber all went online at exactly the same time.
