mrchillie: Argh pathetic! I wish it were easy to change providers on UFB!

If you want to buy your way out of the contract then there is no reason why you can't. There won't be any way to avoid term contacts and penalty fees though - when you enter into a contract with your ISP for a UFB install they're also entering into a contact with Chorus or the LFC concerned.

The exact same issue will arise if you want to move properties, it's not quite like DSL.

I mean someone told me there's a suspicion why some UFB connections are not performing as well as intended. Apparently not all ISPs are aware and some are investigating. Let's see what they find.

Has anybody who's seeing issues done any testing of their high priority CIR queue to see how the performance is of that?

People do need to remember that residential connections are simply an EIR and that there is no CIR on this, ie your 30/10 is EIR, the 2.5Mbps CIR is only for tagged traffic.

that's not what the general population believe though :)

I thought all the traffic was vlan tagged or something? if not then what traffic is tagged?

That's different from QOS. Only the QOS tagged traffic is subject to the CIR. (Any tagged traffic over that CIR is/can be dropped).

The CIR in this case on UFB basically means nothing. (Other than perhaps being used for VOIP?)

Exactly. I think if you polled 99% of the tech community who know what UFB is you'd find most believing that the much talked about CIR applied to their total bandwidth, ie 2.5Mbps CIR on a 30Mbps downstream rather than the entire 30Mbps being EIR.

The CIR is really just there for low latency, guaranteed throughput applications such as voice and video conferencing etc. At present the only real use will be voice traffic from ISP's who are tagging voice traffic.

Exceed the CIR and packets are dropped. This is the same way the CIR works on EUBA plans with CIR's, and existing services such as HSNS. It introduces challenges in running services as you have to carefully dimension each end to ensure you don't exceed the CIR.

It doesn't help that some people are talking about 2.5 megabit CIR, when really that should be an implementation thing at this time. Like prioritised VOIP.

I'd rather 2.5 megabit CIR over all my traffic really. That said I get by ok on ADSL without any CIR.

The challenge for Chorus / LFC's and ISP's is actually engineering the CIR - in effect allocating 2.5Mbps of guaranteed traffic to users when this bandwidth will sit dormant for most of the time.

Apart from the odd issue EUBA has worked relatively well with no per user dimensioning.

It doesn't matter because probably no one is going to use the voip port on the ONT nor the CIR tagged traffic for consumer plans.

Pretty much every ISP is just using EUBA0, not bothering with vlan tagging and just sending voip over the best effort internet bandwidth then doing some QoS/management/engineering of traffic inside the ISP network to smooth things out.

This is probably going to continue for UFB

Having CIR's for special tagged traffic on the consumer bitstream offerings seem like a retarded waste of time to me.

Business plans sure.

maybe they should make regualr http traffic have the 2.5Mb/s cir, so that the guy down the road with the dedicated torrent machine doesn't slow down the tech savvyy grandma who likes to browse trademe quickly?

2.5megabit/sec isn't quick.

As usage (and hence risk of congestion) ramps up, it will be necessary to use tagging on VoIP traffic to ensure quality. Keep in mind that tagging can be done from the Ethernet side of the ONT, too, so it's not exclusive to the analog ports on the ONT.

This isn't VLAN tagging, it's basic 802.1p tags. There is no reason why every ISP presently offering VoIP services over UFB isn't doing this, since it's a simple matter of ensuring that the SIP and RTP traffic is using the correct high priority tag (4 in the case of NGA evolve). For NGA business it's also 4, but the way tags are handed depends on whether transparency is on or off.

EUBA works in exactly the same way - if you have EUBA40,90 or 180 the class of service design looks at the 802.1p tag to decide what is high and what is low priority.
