Be with me, as I take you through\u00a0a list of use cases of Transport SDN. Then tell you what the TWO important \u201cKiller use cases\u201d<\/b> are for Transport SDN. ( and give you reason why I shortlisted two)<\/p>\n
So, here are two goals of my blog<\/strong>:<\/span><\/p>\n a) If you are an operator, you will get an insight about the important use cases of Transport SDN. So that you can engage with vendors fruitfully; ask right questions and perhaps influence their roadmap.<\/p>\n b) If you are a vendor, you get to know an operator\u2019s perspective about Transport SDN\u2019s priorities.<\/p>\n But before we proceed I intend to tell you why this whole discussion is so important, in the first place.<\/p>\n As SDN is still immature, vendors have taken advantage of associating SDN with any feature and product they want to market. It is so easy to sell anything if\u00a0 dubbed as \u201cSDN\u201d, after all.<\/p>\n It is NOT uncommon for a vendor to come and present ten use cases for SDN and then tell you what would be the right fit for you; which will of course match its roadmap.<\/p>\n So someone ought to separate wheat from chaff.<\/p>\n And that is you –\u00a0the operator!<\/p>\n And if you know what the important applications for Transport SDN are, you can easily engage with\u00a0 SDN vendors and drive\u00a0them rather than vice versa.<\/p>\n Before that, you should understand one important thing<\/strong><\/span>!<\/p>\n Transport world is already SDN like when it comes to concepts.<\/p>\n How ?<\/p>\n Control and forwarding plane are well separated and networks controlled and\u00a0 driven by central network management systems (two important attributes for SDN).<\/p>\n Add to these, features of\u00a0openness\u00a0\u00a0for the interfaces and\u00a0 Open APIs (ongoing work by vendors) and you are well on the path of full-fledged SDN.<\/p>\n So SDN in the transport world should not be as big of a paradigm shift as it is for the data center world.<\/p>\n Bottom line! The vendors should take time and evolve their transport SDN roadmaps to solve real transport world issues. Instead I see some transport vendors try to emulate all the data center use cases which might lead to putting square pegs in round holes.<\/p>\n Therefore!<\/p>\n <\/p>\n So what are these issues and how do they relate to the use cases?<\/p>\n To answer this question we proceed as following:<\/p>\n My Benchmark for the Killer Transport SDN Use case is following<\/p>\n 1. It should solve pressing issues of an operator.<\/p>\n 2. It should reduce both CAPEX and OPEX<\/p>\n Now lets move to the use cases.<\/p>\n The four Use Cases from ONF are following:<\/p>\nTop Transport SDN use cases should solve real issues!<\/span><\/h5>\n
