Re: Everything MLPPP

A few questions folks ..

--
First question has to do with topology/vlans/pppoe ..

Here's my simple network topology. In words I have two Thomson
516v6's connected to a close-by ethernet switch, then about 40 ft
of cat5e and another ethernet switch. And connected to that second
switch is my mlppp/pppoe box -

          ___        ___
516v6x--x|   |      |   |
         | X |x----x| X |
516v6x--x|___|      |___|x--x mlppp/pppoe box
	   ^    ^     ^
           |    |     |_ second gige switch
	   |    |
	   |    |_ 10m cat5e
	   |
	   |_ first gige switch

What I'd like to do is to create a vlan on one of the thompson's,
say vlanid = 9 just for sake of argument, so that I can direct my
second pppoe connection to run on that vlan so that it's certain
that that connection will get directed to the secondary thomson.
I've empirically verified that with only one Thompson in the network
I can create multiple links on the one device, so I'm thinking that
I need some way of partitioning the two modems (vlan) so that hilarity
won't ensue once I enable the second modem. :)

Has anyone attempted this and might know the Thomson cli incantation for
creating vlans? I'm tempted to just yank user.ini off of the Thomson
and change the default vlan to be 9.

Second question has to do with MRRU's and link latency and throughput
parameter tuning ..

Here are my current LCP negotiated settings -

[L1] show lcp
LCP [Opened]
Self:
        MRU      : 1492 bytes
        MAGIC    : 0x5ff944db
        ACCMAP   : 0x000a0000
        ACFCOMP  : No
        PROTOCOMP: Yes
        AUTHTYPE : none
        MRRU     : 4096 bytes
        SHORTSEQ : No
        ENDPOINTDISC: [802.1] 00 0d b9 0d 02 50
Peer:
        MRU      : 1492 bytes
        MAGIC    : 0x2c863d13
        ACCMAP   : 0xffffffff
        ACFCOMP  : No
        PROTOCOMP: No
        AUTHTYPE : PAP
        MRRU     : 32719 bytes
        SHORTSEQ : No
        ENDPOINTDISC: [LOCAL] 34 36 30 37 32 31 30 30 39 31 00 00 00 00 00

Firstly I'm assuming MRU should be the same as normal single link ppp. So I'm
pretty confident about 1492.

Now the MRRU on the other hand is kind of intriguing. I've read through the 7
or so pages of posts on this thread and see that folks have commented on atm
cell payload size and the like as it relates to MRRU, but what's up with the
Teksavvy 'peer' having a huge MRRU of 32719?  Far as I know this violates the
PPPOE RFC which I think says 4096 bytes. And what relation (if any) does 32719
have to atm cell payload size?

$ bc -l
32719/53
617.33962264150943396226
32719 - (617*53)
18

Can folks comment on what the best setting is for my side's MRRU?  Should I be
matching Teksavvy's setting?

And one final question wrt to link latency and bandwidth.

I have the ability to tweak these, here are my current settings -

[L1] show link
Link L1 (static):
Configuration:
        Device type    : pppoe
        MRU            : 1492 bytes
        MRRU           : 4096 bytes
        Ctrl char map  : 0x000a0000 bytes
        Retry timeout  : 2 seconds
        Max redial     : unlimited, delay 1s
        Bandwidth      : 800000 bits/sec
        Latency        : 5 usec
        Keep-alive     : every 5 secs, timeout 75
        Ident string   : ""

First of all my assumption is that both bandwidth and latency pertain only
to Transmit (ie uplink) characteristics of my link. So I've set my bandwidth
to match what my modem is reporting as my upstream bandwidth.

Latency apparently is only important when the links have different
characteristics which is in this case is not a concern. Any non-zero small
value seems to be fine.

So my final question simply whether folks have experience to share wrt
my bandwidth and latency assumptions.

Thanks in advance for your help! :)

For any routers that need K26 (Kernel Linux 2.6) like Linksys WRT320n, there is a tomato mod called DualWAN which apparently does support MLPPP (single and multi). Unfortunately, the official site and the firmware itself is Chinese only.

Recently I found out somebody translated it in English. See postings here: »www.linksysinfo.org/index.php?th···3/page-8.

I do not know when I will have time to try it (currently running with DD-WRT), but if anybody here does try it, please post the results.

reply to TSI Martin
Hey guys, I'm an idiot when it comes to MLPPP. If I add MLPPP with TekSavvy, do I need a proper router or change settings or will it work right away without me not doing anything on my part to stop torrent throttling. My Ubuntu distro says it needs one week to download and I can't take it anymore!

Thanks for the help!

you need a router with dd-wrt or tomato as mentioned in the OP which has MLPPP features.

reply to TSI Martin
For 3 or 4 lines, TekSavvy suggests the RouterBoard RB750GL. It is apparently an awesome piece of hardware, and only costs approx $70.

However, the unit comes with ZERO documentation, and the online docs assume you are working with a different model that has a serial interface. (And I had to complain to Mikrotik to get that added recently. Before that, there was nothing.)

I've poured over countless forum posts, each with bits of info - which likely do NOT go together. TekSavvy does not support the setup, but apparently Acanac offers a beautiful script for the unit. Just enter your user/pass and you are done. Why can't TekSavvy do that?

I've got a /27 subnet from TekSavvy and I REALLY need to get this going.

Is there anyone out there with a bunch of static IPs and a RB750GL that can send me screen shots of the Winbox configuration windows to help me figure this out? If not, I guess I am expected to reverse engineer the embedded code on the chips.

Thanks in advance for your effort.

reply to TSI Martin
Is it possible to use MLPPP with VDSL2? (Specifically the 25/7 package from Teksavvy)

Thanks!

reply to TSI Martin
Hi
I have tried to find out this info, because i know there are a slew of messages concerning.... but.... specifically, does the Netgear WNDR3700 support Single Line MLPPP?
I read that the newer version 2 as of two weeks ago now will work with DD-WRT. Is this the firmware I will need to get it up and running?

My goal is to get a stable router running Wireless N and Single LIne MLPPP that is scaleable if I upgrade my DSL speed. I currently have a Linksys WRT54GL that works well, but it's not Wireless N.
Thanks

pretty sure that's the router I picked up (I'll check when I get home), my understanding is that all routers will recent versions of DD-WRT installed will support single line MLPPP.

Works without an issue for me

reply to TSI Martin
so if im only getting 1.5meg down and .5 meg up if i was to set up lets say a 2 connection MLPPP would i be getting 3meg down and 1 meg up? or would it strengthen the line quality and make things better?

MLPPP has no effect on your DSL connection (ie, what happens between the ISP and the modem). If you have a DSL connection that is getting 1.5/0.5, then the best you can hope for by adding another connection is 3/1.

reply to TSI Martin
ya thats what i thought, thank you.

reply to TSI Martin
does anyone know if the router sold by teksavvy for MLPPP supports QoS? If not, how should I incorporate my QoS router into the setup? thank you

If you're referring to the WRT54GL running Tomato/MLPPP, it does.

HI! Does anyone know why the ND version is no longer in the latest build? I have a Asus WL-520-GU and I tried a day ago to load the latest version Alpha 7 and the stable one "Tomato/MLPPP 1.19-mp2 (2.7 MiB)" but did not load on my router after installation.

from my understanding the ND version is specifically for my routers types and wondering why its not in the Alpha4 release?

Another thing is what is the word on support for the Asus RT-N16?
I am interested in this modem for its power, memory and affordability.

Paul

The ND version is hidden in a thread in this forum. I believe it's the announcement thread for the latest alpha.

As for the RT-N16, it uses Linux 2.6, while the Tomato/MLPPP exists only in Linux 2.4. In other words, until somebody does some porting work, 802.11n routers are not candidates for Tomato/MLPPP.

edit: Here you go: »Re: Tomato/MLPPP v3 alpha 7 released!

HI!. thanks for link, so far it works fine with my Asus WL-520GU with Multi-link - Dual lines. With two 5 meg/750k up connects I am getting about on average Dn=9.0 mb Up=1.15. (no longer than usual to connect even when comparing it to a stable dd-wrt version).

Question: I do need more power though. What is the most powerful router that tomato/mlppp supports? I got a HOTSPOT with about 20 (and growing) users and some of them I know use utorrent and vuse.

Paul

Ps, its me Webcan, somehow I got missed up on sites and must have created another account here BY accident. oppps.

Paul

reply to veger
The WL-520GU can handle 15-20 mbps of throughput, although you might run it out of RAM if you really hammer it with torrents.

Have a look at »fw5.net/. I believe the WNDR3700v2 was recently added to the supported list, and should handle 100 mbps or so of throughput.

If you really want to go all out you could install pfsense 2.0 on the x86 hardware of your choice. »pfsense.org I think Linux/MLPPP might still be a viable option if you're handy with a shell. »fixppp.org
