CPC H04L 45/74 (2013.01) [H04L 12/4641 (2013.01)] | 17 Claims |
1. A method for selecting a software defined wide area network (SD-WAN) link using network slice information, the method comprising:
at a software defined wide area network (SD-WAN) controller implemented using at least one processor or a second entity communicatively coupled to the SD-WAN controller and prior to receiving a packet:
subscribing, to a network slice manager, to receive notification for a network slice information provisioning data report via a subscribe managed object instance (MOI);
after a network slice is created, receiving, from the network slice manager, the network slice information provisioning data report via a notify MOI, wherein the notify MOI includes the network slice information; and
using the network slice information to generate or update a record in a data store indicating an association between one or more IP addresses associated with the network slice and transmission characteristics associated with the network slice; and
at the SD-WAN controller:
receiving the packet containing packet header information including at least one internet protocol (IP) address of the one or more IP addresses associated with the network slice;
determining, using the packet header information, a link selection rule for selecting an SD-WAN link for transmission, wherein determining the link selection rule includes determining, using the at least one IP address, the record indicating the transmission characteristics;
selecting, using the link selection rule and the transmission characteristics obtained from the record, the SD-WAN link, wherein the link selection rule uses the transmission characteristics to select the SD-WAN link; and
transmitting the packet via the selected SD-WAN link.
