SixLessonslearned– whatshouldenterprisesbeawareof?
1. Thereisconsiderabledifferenceinwhatismeantby“SD-WAN”– somevendorsarere-brandingexistingnetworksolutionsasSD-WANwithoutanyrealchange
2. EvenwithinsometrueSD-WANsolutions thereisarealgapinfeatureavailabilitybetweenmarketingslidewareandexperienceinthefield– enterprisesoftenonlyfind thisoutduring ProofofConcepts
3. Enterprisesshouldpayattentiontosolutionarchitecture– don’tbefeatureled.Focusonhowthesolution wouldapplytoyourspecificapplicationmixandtrafficengineering requirements
4. SomeISPsarenotreadyforthistechnology– unusualbehaviorseeninthefield includingUDPratelimiting,accidentaloverlaytunnel trafficblockingandpersistentpacketlossissues
5. Globallogisticscannotbetakenforgranted– thereisstillalotofhardwareinvolved!Enterpriseswillneedtoparticipateintheprocessandhavearealawarenessofhowequipment isgoing togettotheirremotesites
6. Achangeinoperationaltools,processesandmindsetsisoften required forasuccessfuladoption.Someenterprisesfind itdifficult tomoveawayfromlocalCLIsanddevice-levelconfigurations
