Abstract: Some embodiments provide a method, executable by a network device, that receives a first set of commands instructing the network device to allow network traffic to egress out of an authentication port of the network device. The authentication port is configured to belong to a first virtual local area network (VLAN). An unauthenticated device is connected to the authentication port. The method further receives a second set of commands instructing the network device to add ports belonging to the first VLAN to a broadcast domain of a second VLAN. The method also broadcasts an address request to the broadcast domain of the second VLAN. The method further receives, from the unauthenticated device, a response to the address request.

Abstract: A method for resource optimized network virtualization overlay transport in a virtualized data center environment includes an optimized virtualized transport mechanism based on MPLS-TP tunneling technology. The transport mechanism may include a usage monitoring and resource usage advertisement mechanism based on IGP-TE protocol extension. Also, the transport mechanism may include a path computation engine (PCE) based optimal path computation for a virtualized transport tunnel used to carry VM-to-VM traffic across the virtualized data center. Additionally, the transport mechanism may include a SDN controller for provisioning and control of virtualized machines and a virtualized transport system.

Abstract: A method for computing device management includes receiving a first incoming packet by a first computing device, analyzing the first incoming packet to identify a virtual network function (VNF) needed to process the first incoming packet, transmitting, to a software defined network controller and in response to the first incoming packet, an orchestration request requesting to orchestrate the VNF on the first computing device, and orchestrating the VNF on the first computing device. The method further includes processing a second incoming packet using the VNF on the first computing device.

Abstract: A method for distributed health monitoring and fault repairing in a switching system. The switching system having one or more supervisory cards, one or more line cards, and one or more switch fabric cards. The method includes transmitting a health status poll request message to the one or more line cards and the one or more switch fabric cards. Thereafter, the method includes receiving health status poll response messages from each of the one or more line cards and the one or more switch fabric cards. Each health status poll response message includes health status summary of the corresponding card. Further, the method involves detecting one or more faults in the switching system based on the health poll response messages. Finally, the method includes triggering at least one action on the detection of the faults in the switching system. These actions are triggered based on a set of predefined rules.

Abstract: A method for allocating data plane resources. The method allocates segments of hardware data plane resources to individual domains. In particular, in one or more embodiments, a new domain data plane request may request multiple segments of hardware data plane resources. In response to the request, a segment is reserved for a domain by assigning a domain identifier of the domain to the segment. Thus, the domain may use the allocated segment.

Abstract: A Continuity Check (CC) protocol optimization method in a switch includes operating a plurality of CC sessions with a peer switch, wherein, for CC intervals, N sessions of the plurality CC sessions are set to a short interval and M sessions of the plurality of CC sessions are set to a long interval, wherein N and M are integers; switching a first session of the N sessions with a second session of the M sessions based on one of a fault and user provisioning; and exchanging the CC intervals between the first session and the second session subsequent to the switching.

Abstract: Embodiments of the disclosure are directed to forwarding multicast packets among disparate Virtual Local Area Networks (VLANs). An embodiment receives a multicast packet matching registration criteria of one or more ports and forwards the multicast packet to the one or more ports, wherein the one or more ports are in a different VLAN than a port from which the multicast packet was received.
