Abstract

With the integration of SD-WAN and third-party SIG, all the traffic from the enterprise client's is forwarded to the SIG over the tunnel. The SD-WAN router at branch office is connected to the SIG over WAN link. Hence there are always bandwidth (aka throughput capacity) limitations for the traffic being routed over the tunnel. For the same reason, service providers would enforce limitations on throughput capacity per tunnel basis. In view of this fact, the effective usage of the link between SD-WAN router and SIG is essential. Also, SD-WAN has enabled customers to prioritize cloud applications and deliver better application performance to their branch network for an always-connected workplace. In fact, SD-WAN helps for the efficient use of the bandwidth from branch locations. As the number of clients and services are ever increasing, there is every need to further optimize the usage of the link between SD-WAN at branch location to the SIG and/or cloud services. The techniques presented herein propose method to consider optimizing the traffic flowing between SD-WAN router and SIG to efficiently utilize the limited tunnel bandwidth available using consolidation, compression, and aggregation methods.
