[AusNOG] I was wondering about ADSL PPPOE\A connection\lines aggregation options.

[Ryan Crouch]

Hey Eliezer,

We have numerous clients in a similar position however the use of MLPPP
has often been the most problematic deployment option. The main reason for
this is (particularly on DSLAM's from big T) is the path from the DSLAM to
the BRAS and subsequently the LNS doesn't always support it, and can also
take differing paths. When this is the case, the differences cause
problems for MLPPP and it either gets torn down or gives unreliable data
flows.

We use Cisco LNS across our network and customers are typically using
Cisco CPE.

For customers with VoIP or sensitive interactive traffic like ICA/RDP you
need to use per-flow based balancing. You do reach your aggregate
throughput, but not on any singular data stream.

For customers looking for throughput alone (and packet sequencing isn't as
important) per-packet based balancing works fine.

>From experience, bonding the Sessions is typically a bad idea. This is
particularly true for SP's where you're not landing on the same LNS with
both sessions.

If you don't have an ISP that can work with you on this solution, CPE
based Round Robin/balancing will be easiest option for you in this case.

Kind Regards,

Ryan

Subject: [AusNOG] I was wondering about ADSL PPPOE\A connection\lines
aggregation options.

I am asking here because there is a slight chance that here the more
technical people knows the answer.

I was wondering about the options to aggregate DSL or PPPOE\A
connections since my location is about 5-6 KM from the local ADSL
junction.
I cannot place a fiber optic cable but I can use two or more ADSL lines.
I know that there are probably technological options to aggregate the
DSL lines from 2-3 to one logical connection.

If anyone have used this kind of solution or used multiple PPPOE\A
connections to allow more bandwidth I am wondering about the options.

Another option is to connect using two different PPPOE\A connections to
multiple ISPs and load balance between the IP connections.
Anyone knows about solutions for that?

I can use a mikrotik device which will load balance in a round robin
like way but I was wondering if there are other options to LB.

Thanks,
Eliezer
