Abstract: A system and a method for configuring resources over a network cloud are described. Attributes related to user roles i.e. categories of user roles, network cloud based services associated with each category, and a number of users associated with each category are received. Hardware capabilities and/or network capabilities corresponding to the attributes are determined from a mapping table stored in a repository. A service set capable of providing the hardware capabilities and the network capabilities is determined from the mapping table stored in the repository. The mapping table is based on previous implementations and instructions associated with one or more service sets. Resources are configured over the network cloud to implement the service set.

Abstract: Systems and methods are provided for providing a clustering solution and a Virtual Router Redundancy Protocol (VRRP) platform for a branch deployment of at least a first gateway and a second gateway. The VRRP platform can be associated with a VRRP Internet Protocol (IP) address and the first gateway configured as a VRRP master. A change in an operational status of the first gateway can be determined with the clustering solution. The second gateway can be caused to be configured, with the clustering solution, as a new VRRP master. Network traffic associated with the VRRP Internet Protocol (IP) address can be received. The second gateway can be caused to forward the network traffic.

Abstract: The present disclosure discloses a method and network device for dynamic detection of inactive virtual private network clients. Specifically, a network device receives periodic messages from a first device at a first interval, and determines a timeout value for the first device based at least on the first interval, at which the periodic messages are received from the first device. Subsequent to determining the timeout value, the network device detects that a message has not been received from the first device for a period of time corresponding to the timeout value for the first device. The network device then terminates at least one connection with the first device responsive to determining that no message has been received from the first device for the period of time corresponding to the timeout value for the first device.

Abstract: Example implementation relates to a method of failure detection and seamless traffic switchover in a VPN system. A cluster of nodes exchange heartbeat messages to detect a failure at a first node in the cluster. When failure is detected at the first node, a master node transmits a failover message to a network end node connected to the first node. The failover message includes a list of active nodes to which traffic may be routed. The network end node updates its routing table based on the failover message and switches the traffic to a second node in the cluster of nodes.

Abstract: Data transfer for access points or switches in a cluster upon data tunnel failure is described. An example includes receiving uniform mapping information for a cluster including a bucket map mapping an active gateway and a standby gateway for each of multiple entries, the bucket map including mapping a first gateway node as a standby gateway and a second gateway node as an active gateway for an entry. Synchronized user information is received from the second gateway node including identification of a user indexed to the first entry. A message is received from a first AP or switch requesting activation of the user on the first gateway node as a standby gateway upon failure of a data tunnel between the first AP or switch and the second gateway node. The user is activated on the first gateway node.

Abstract: Example implementation relates to a method for establishing a dynamic VPN tunnel between branch gateway devices based on metric data. A branch orchestrator receives metric data from VPNC device. The metric data includes data center bandwidth and processor utilization of the VPNC device. The metric data is derived from the traffic being routed via the VPNC device. When the metric data associated with traffic between a first branch gateway device and a second branch gateway device is above a Service Level Agreement (SLA), a dynamic branch to branch VPN tunnel is established to route the traffic between the first branch gateway device and the second branch gateway device. The VPN tunnel between the branch gateways can be teared when the load at the VPNC device reduces.

Abstract: A system for facilitating the dynamic selection of a gateway at an access node is provided. During operation, the system can select primary and standby gateways for a client device coupling the access node from a list of gateways associated with a gateway cluster based on an identifier of the client device. The gateway cluster can include a plurality of gateways coupled to the access node. The system can then forward traffic from the client device to the primary gateway. If there is a change in a set of parameters associated with the gateway cluster, the system can receive a policy indicating a change of gateway for the client device. The set of parameters indicates performance associated with the plurality of gateways. The system can select a new primary gateway for the client device based on the policy and redirect traffic from the client device to the new primary gateway.

Abstract: Systems and methods are provided for reducing WAN bandwidth consumption used by multicast for large scale software-defined branch deployments. In particular, a cloud-based multicast orchestrator may be implemented as part of an SD-WAN service. This cloud-based multicast orchestrator may orchestrate routes for multicast traffic between a multicast source and the various branches of the large scale software-defined branch deployment. This cloud-based multicast orchestrator may orchestrate routes for multicast traffic which reduce/optimize WAN bandwidth consumption. In combination with the cloud-based multicast orchestrator, examples may utilize a branch gateway hierarchy which designates one branch gateway a “leader” for a given multicast stream to further reduce WAN bandwidth consumption used by multicast.
