Using purely OTN services gives you a much more consistent control over your network, this being said then generally you are buying unprotected raw links so normally you are responsible for your own diversity links are normally 1G, 10G, 100G not sub rates. With OTN links there is no packetization, QOS or re-writing on the underlying layer. It does not matter what load is on your carriers network, every tiny bit of capacity is yours and your alone, they cannot over-subscribe it only you can. Also, very large MTU is normally available. If you are not a carrier of carriers (you do not sell transport to downstream carriers) then an MPLS based service with fast reroute capability is normally perfectly fine and appropriate.<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=EN-US>From:</span></b><span lang=EN-US> AusNOG <ausnog-bounces@lists.ausnog.net> <b>On Behalf Of </b>David Smith<br><b>Sent:</b> Friday, 29 June 2018 12:30 PM<br><b>To:</b> ausnog@lists.ausnog.net<br><b>Subject:</b> Re: [AusNOG] Telstra ELINE P2P<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Pardon my ignorance here and I'm not trying to hijack the thread but what is the benefit of a "<span style='font-size:9.5pt'>true L1 service" over "<span style='background:white'>an MPLS variant"?</span></span><o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span style='font-size:9.5pt;background:white'>Jason, what metrics do you consider when evaluating these services?</span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span style='font-size:9.5pt;background:white'>I'm interested in getting the 0's and 1's from point to point around the country and I've been basing my purchasing decisions on the offered (upstream carrier) SLAs rather than the transmission technology.</span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span style='font-size:9.5pt'>Regards,</span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span style='font-size:9.5pt'>Dave</span><o:p></o:p></p></div></div><div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>On 29 June 2018 at 21:21, JASON BOTHE <<a href="mailto:jbothe@me.com" target="_blank">jbothe@me.com</a>> wrote:<o:p></o:p></p><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0cm 0cm 0cm 6.0pt;margin-left:4.8pt;margin-right:0cm'><p class=MsoNormal><br>Greetings<br><br>I am evaluating wave services between Syd and Melb, and Telstra is proposing ELINE P2P which they state is a true L1 service and not an MPLS variant.
