Abstract: A method implemented by network element (NE) configured as a local cloud switch point (CSP), the method comprising receiving a first post message from a remote CSP via a cloudcasting network, wherein the first post message indicates a remote virtual extensible network (VXN) identifier (ID) of a remote virtual network attached to the remote CSP, receiving a first data packet from a local virtual network attached to the local CSP, wherein the first data packet is associated with the remote virtual network, performing encapsulation on the first data packet to produce a first encapsulated data packet by selecting an encapsulation header for the first data packet based on the remote VXN ID and not based on network protocols of the local virtual network and the remote virtual network, and sending the first encapsulated data packet to the remote CSP.

Abstract: In a source provider edge (PE) router, a method of forming a data multicast distribution tree (MDT) comprising the steps of monitoring a rate of multicast data traffic within a default MDT, determining that the rate exceeds a threshold, sending a join message to at least one receiver PE router in response to the determining, wherein the join message comprises a MDT number that identifies the data MDT, receiving a path message from the at least one receiver PE router and thereby forming the data MDT, and sending multicast data traffic via the data MDT.

Abstract: A computer program product comprising computer executable instructions stored on a non-transitory medium of an upstream node in a network system comprising a plurality of nodes that when executed by a processor cause the node to advertise an upstream assigned label to a downstream node, receive a message from the downstream node, and if the received message confirms that no conflict with the upstream assigned label exists at the downstream node, assign the upstream-assigned label, or if the received message confirms that a conflict with the upstream-assigned label exists at the downstream node, either select a new upstream-assigned label or wait until indication is received that the label resource has become available.

Abstract: Embodiments relate generally to systems and methods for transitioning a system from a tradition network to a Software Defined Network (SDN) enabled network. In some embodiments, the systems and methods may comprise the use of a Path Computation Element (PCE) as a central controller. Smooth transition between traditional network and the new SDN enabled network, especially from a cost impact assessment perspective, may be accomplished using the existing PCE components from the current network to function as the central controller of the SDN network is one choice, which not only achieves the goal of having a centralized controller to provide the functionalities needed for the central controller, but also leverages the existing PCE network components.

Abstract: A method of batch processing implemented using a pre-classification mechanism of a network interface controller is provided. The method includes receiving, by the pre-classification mechanism of the network interface controller, rules for populating a first receive queue and a second receive queue, receiving, by the pre-classification mechanism, packets corresponding to a first protocol intermingled with packets corresponding to a second protocol, and populating, by the pre-classification mechanism of the network interface controller, the first receive queue exclusively with the packets corresponding to the first protocol and the second receive queue exclusively with the packets corresponding to the second protocol based on the rules such that a central processing unit is able to obtain a first batch of the packets from the first receive queue and process each of the packets from the first batch using a same node graph path.
