    Abstract: Some examples relate to managing multicast group traffic. In an example, a switch anchor controller receives a request for a multicast group from an associated network switch in a multicast-capable network. The associated network switch registers to the switch anchor controller in the multicast-capable network. In response to the request, the switch anchor controller selects a non-anchor controller in the multicast-capable network to serve the multicast group to the associated network switch. The switch anchor controller provides the information related to the non-anchor controller to the associated network switch, which in response creates a specific multicast tunnel between the associated network switch and the non-anchor controller to transfer multicast traffic related to the multicast group.

    Abstract: In an example, a Dynamic Host Configuration Protocol (DHCP) lease request from a client device connected to a network is received. Based on the DHCP lease request, an Internet Protocol (IP) address is assigned to the client device for a lease time. A first lease renewal request is received. A probability of utilization for a lease time block is predicted based on a historical lease pattern, device characteristics, traffic information, and DHCP information. Based on a combination of the probability of utilization and a reward value, the lease time block is allotted for lease renewal. For each allotment, the reward value is adjusted based on deployment characteristics and traffic load in the network, and a network connection duration of the client device. A normalized reward value for the lease time block is determined based on reward values for the lease time block over multiple allotments.

    Abstract: An example branch gateway includes processing circuitry, memory including instructions, and a plurality of ports. The branch gateway transmits, from a plurality of ports, a first broadcast message. The branch gateway receives, in response to the first broadcast message, response messages on respective ports. The branch gateway determines, based on a receipt order of the response messages, an identifying address from a first response message. The branch gateway assigns the respective port for each response message to a unique VLAN. The branch gateway determines, for each port assigned to a unique VLAN, a link health parameter. The branch gateway selects a primary port to connect to an activation server of a WAN. The branch gateway selects a secondary port to connect to the activation server.

    Abstract: Examples described herein include a method and system for determining a number of controllers in a Network Authentication Server (NAS) controller cluster, wherein each of the controllers in the NAS controller cluster includes a unique Physical Internet Protocol (PIP) address; creating a number of unique Virtual Internet Protocol (VIP) addresses for use by an external authentication server (EAS) to communicate with the controllers in the NAS controller cluster, wherein the number of VIP addresses is to be proportional to the number of PIP addresses; and mapping each controller in the NAS controller cluster to a plurality of VIP addresses, wherein the VIP addresses are to have different priorities for different controllers in the NAS controller cluster.
