US Patent 11431618 Flexible path encoding in packet switched networks

Various example embodiments for supporting packet forwarding in communication networks are presented. Various example embodiments for supporting packet forwarding in communication networks may be configured to support forwarding of source routed packets in packet switched networks based on flexible path encoding. Various example embodiments for supporting forwarding of a source routed packet based on flexible path encoding may be configured to support forwarding of the source routed packets based on use of a bit string configured to encode the path for the source routed packet. Various example embodiments for supporting forwarding of source routed packets based on flexible path encoding may be configured to support forwarding of source routed packets based on various types of source routing, such as Segment Routing (SR), SR-Traffic Engineering (SR-TE), or the like.
