Then, they may need some platform to provide observability and potentially dynamic re-routing of LSP's based on actual or predicted congestion situations. If traffic patterns and utilization are not ideally deterministic, then skip the bandwidth reservation and ensure that the automation is in place to reroute traffic when necessary.</div><div class="gmail_default" style="font-family:'verdana' , sans-serif;color:#444444"><br></div><div class="gmail_default" style="font-family:'verdana' , sans-serif;color:#444444">I know, adding complexity, but if you just can't build the links you would want, this may be a way to work with what you've got.</div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><br><div dir="ltr" style="margin-left:0pt" align="left"><table style="border:none;border-collapse:collapse"><colgroup><col width="253"><col width="242"></colgroup><tbody><tr style="min-height:133.5pt"><td style="border-width:0.99375pt;border-style:solid;border-color:rgb( 255 , 255 , 255 );vertical-align:top;padding:5pt;overflow:hidden"><p dir="ltr" style="line-height:1.44;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:'arial';background-color:transparent;vertical-align:baseline;white-space:pre-wrap">Best Regards,</span></p><p dir="ltr" style="line-height:1.44;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:'arial';background-color:transparent;vertical-align:baseline;white-space:pre-wrap">Mauricio Rodriguez</span></p><p dir="ltr" style="line-height:1.44;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:'arial';background-color:transparent;vertical-align:baseline;white-space:pre-wrap">Founder / Owner</span></p><p dir="ltr" style="line-height:1.44;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:'arial';background-color:transparent;vertical-align:baseline;white-space:pre-wrap">Fletnet Network Engineering (</span><a href="http://www.fletnet.com/"><span style="font-size:11pt;font-family:'arial';color:rgb( 17 , 85 , 204 );background-color:transparent;vertical-align:baseline;white-space:pre-wrap">www.fletnet.com</span></a><span style="font-size:11pt;font-family:'arial';background-color:transparent;vertical-align:baseline;white-space:pre-wrap">)</span></p><b>Follow us</b> on <a href="https://www.linkedin.com/company/fletnetnetworks">LinkedIn</a><br><br><p dir="ltr" style="line-height:1.44;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:'arial';background-color:transparent;vertical-align:baseline;white-space:pre-wrap"><a href="mailto:Mauricio.Rodriguez@fletnet.com">Mauricio.Rodriguez@fletnet.com</a></span></p><p dir="ltr" style="line-height:1.44;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:'arial';background-color:transparent;vertical-align:baseline;white-space:pre-wrap">Office: <a href="tel:+17863091082">+1 786-309-1082</a></span></p><p dir="ltr" style="line-height:1.44;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:'arial';background-color:transparent;vertical-align:baseline;white-space:pre-wrap">Direct: <a href="tel:+17863095493">+1 786-309-5493</a></span></p><br></td><td style="border-width:0.99375pt;border-style:solid;border-color:rgb( 255 , 255 , 255 );vertical-align:top;padding:5pt;overflow:hidden"><p dir="ltr" style="line-height:1.656;text-align:center;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:'arial';background-color:transparent;vertical-align:baseline;white-space:pre-wrap"><span style="border:none;display:inline-block;overflow:hidden;width:151px;min-height:100px"><img src="https://lh3.googleusercontent.com/odplYLLHLLWWC2sTnIvOt-aGYo7rDnK5KkZhRx3-h2ogNZvNIYEits12o-XTriRUbKpywBg9G4PGkYv1-ynMlZOZL2hu2UBCgVXzejTlkQzoJQuknTVaYOQuh2yjkQ5f-0tZ2Kp9" width="151" height="150.66666666666666" style="margin-left:0px"></span></span></p></td></tr></tbody></table></div><div dir="ltr" style="margin-left:0pt"><table style="border:none;border-collapse:collapse"><colgroup><col width="254"><col width="243"></colgroup><tbody><tr style="min-height:0pt"><td style="border-width:1pt;border-style:solid;border-color:rgb( 255 , 255 , 255 );vertical-align:top;padding:5pt"></td><td style="border-width:1pt;border-style:solid;border-color:rgb( 255 , 255 , 255 );vertical-align:top;padding:5pt"></td></tr></tbody></table></div></div></div></div></div></div></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Oct 13, 2021 at 1:33 PM Adam Thompson <<a href="mailto:athompson@merlin.mb.ca">athompson@merlin.mb.ca</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb( 204 , 204 , 204 );padding-left:1ex">

I've got a downstream customer asking for help; they have a private internal network that I've taken to calling the "partial-mesh network from hell": it's got two partially-overlapping radio networks, mixed with islands of isolated fiber connectivity.</div>

Dynamic routing protocols (IS-IS, OSPF, EIGRP, etc.) generally will only select the _best_ path, they won't spread the load unless all paths are equal - and they are very unequal in this network, ECMP would likely fail horribly.<br>

The network is becoming bandwidth-limited, so they're wanting to make use of all available paths, not just the single "best" path. It's also remote and spread out, so adding new links or upgrading existing links is difficult and expensive.</div>

Has anyone come across any product or technology that can handle the multi-path-ness and the private-network-ness like a regular router, but also provides the intelligent per-flow path steering based on e.g. latency, like an SD-WAN device (and/or some firewalls)?</div>
