RE: Level3 Internet service, out of order packets causing issues

[Mark Wicker]

Hi Jason,

I think that this was it. The first octet of our router’s Level3 facing 
interface MAC is a 6. Changed it to 0 and it does look much better now. Thanks!

Subject: Re: Level3 Internet service, out of order packets causing issues

Hi Mark,
I'm going to throw out a guess here.  By any chance, is the first octet of your 
router's MAC address a 4 or a 6?
In general, modern routers do not load balance per-packet, which is what caused 
out-of-order issues in days gone.  Load balancing is usually done based on a 
hash of the source and/or destination IP of the packet, MPLS label, or Ethernet 
(on a switched interface).  The most common cause for actual unordering of 
packets/frames in a modern service provider network, in my experience, is 
actually this hashing mechanism.  Many vendor's hashing implementations assume, 
based on position in the frame, that a frame with a MAC address beginning with 
4 or 6 is an IPv4 or IPv6 frame, not an MPLS frame.  This can result in out of 
order packets.  The most common fix is control word being applied on a 
pseudowire (assuming you are being carried across a pseudowire in the SP 
network), but if this is what is occurring, you could also resolve the issue by 
changing your MAC address.

Hi,

I have 1G Level3 ethernet dedicated internet service as one of my ISP's at my

have been troubleshooting it with a directly connected machine (publically 
addressed, no firewall, nothing between this machine and our Level3 router). I 
have taken several packet captures while accessing various sites and have 
noticed large numbers of out of order packets which are wreaking havoc with TCP 
connections and other traffic. In my experience, per-packet load balancing 
across various different links can cause this issue. I do not see this behavior 
with my other ISP's. I have had several tickets opened with Level3 but have had 
no success. Any help here? Anyone out there seen this and have any contacts 
that may be able to help?


FYI - we own our own public IP space and advertise via BGP to Level3. Currently 
I am using a dedicated /24 of our space advertised to Level3 only to ensure 
that the return path is through Level3 and not another ISP. Also, everything is 
single linked from a layer 2 and 3 perspective from the router to the test 
machine to ensure that the cause of any out of order packets is not on our end.


Thanks,

Re: Common Reliable Out Of Band Management Options at Carrier Hotels

[Faisal Imtiaz]

I think you will have a tough time finding a universal solution that will fit 
for all DataCenters (speaking in the context of OOB communication method).

Traditional connections via Ethernet / T1 /Phone lines will cost you a fair 
amount (monthly service and cross-connect).

In some of the DataCenters you can use a cellular (M2M ) based solution.. (use 
something like a cradle point or other similar functioning devices) 

In many of our DC we will exchange (bidirectional) OOB connection with another 
network (which is multi-homed).
Quite a few of the DC's also provide Courtesy Wifi for customer's use .. it is 
possible to configure an OOB to use that connection.. (takes a bit of 
creativity).

Since part of our network is using Fixed Wireless Technologies, we are pretty 
familiar with Mikrotik Routerboards they have a number of small, inexpensive 
devices which allow for very flexible configurations (including devices with 
USB ports that support USB Cellular dongles).

Re: Common Reliable Out Of Band Management Options at Carrier Hotels

[Luke Guillory]

Cell site has one network in and out, that being the providers own network.

This data center has many transit providers blended into their DIA while I 
might only have two at the location.

While cell sites in larger cities might be in better shape than down here in 
the south, I've seen way to many go down around here from storms.

What's makes ATT LTE network different from the ATT transit network that sits 
in the datacenter? While it gives me access to a network outside the datacenter 
it seems to limit me to only one network.

Very strange. Everytime it was open for all companies need IP network

And it is still possible to open a RIPE LIR for offshore companies like

carrier hotels? What constraints might present themselves at those locations?"


Assuming each hotel we are located in can provide either Ethernet or DSL 
I'm guessing that is going to come a cost (cross-connects, rack space etc..) 
that might end up being cost prohibitive.


So my inquiry is... What does the list find to be a reasonably priced yet 
reliable solution in carrier hotels for OOB? Or is that contradictory :)


Thoughts on Cellular?


Any experience/insight would be appreciated.


Thanks,


Darin
