    Abstract: A method and system for managing connections with a distributed control plane is provided. The method includes generating, by a router, a controller identifier (ID) list comprising a plurality of controller group IDs of a plurality of controller groups, wherein one controller group ID uniquely identifies one controller group. The method also includes identifying a first controller group, by the router from the list, with which a connection is to be established. Further, the method includes establishing, by the router, the connection with a controller of the first controller group if at least one of following conditions is met 1) the router has not exhausted maximum number of connections, 2) the router has previously had a connection with the controller of the first controller group, and 3) the router has an existing connection with a controller of a second controller group not present in the list.

    Abstract: A method may include determining, by a first network device, a type of control channel to open across a transport in a software-defined network (SDN). The method may also include establishing the control channel with a control device via a control plane that is separate from a data plane. The method may further include advertising first security association parameters to the control device via the control channel. The method may include receiving, from the control device via the control channel, second security association parameters associated with a second network device. The method may also include establishing a data plane connection with the second network device using the second security association parameters.

    Abstract: A system may include a first border network device located between a first network domain and a third network domain, and a first edge network device in the first network domain, where the first edge network device may be configured to receive a packet. The packet may be directed to a second edge network device in a second network domain. The first edge network device may also be configured to add a second label to the packet that identifies a second border network device located at the border of a second network domain and the third network domain. The third network domain may be located between the first network domain and the second network domain. The first edge network device may additionally be configured to add a first label to the packet that identifies the first border network device, and route the packet to the first border network device.

    Abstract: A method for creating a secure network is provided. The method comprises establishing an overlay domain to control routing between overlay edge routers based on an underlying transport network, wherein said establishing comprises running an overlay management protocol to exchange information within the overlay domain; in accordance with the overlay management protocol defining service routes that exist exclusively within the overlay domain wherein each overlay route includes information on at least service availability within the overlay domain; and selectively using the service routes to control routing between the overlay edge routers; wherein the said routing is through the underlying transport network in a manner in which said overlay routes is shared with the overlay edge routers but not with the underlying transport network via the overlay management protocol.
