Abstract
Various example embodiments for supporting an in-band control plane are presented. Various example embodiments for supporting an in-band control plane may be configured to support an in-band control plane in a Multiprotocol Label Switching (MPLS) network. Various example embodiments for supporting an in-band control plane in an MPLS network may be configured to support an in-band control plane in an MPLS network by supporting exchange of control protocol packets of control protocols as MPLS packets, such that the control protocol messaging is in-band along the MPLS data plane itself. Various example embodiments for supporting an in-band control plane in an MPLS network may be configured to support an in-band control plane in an MPLS network by supporting communication of MPLS packets that encapsulate control protocol messages of control protocols with an MPLS label which indicates that the payloads of the MPLS packets carry the control protocol messages of the control protocols.
