Software defined wide area network uplink selection for a cloud service can include a network controller to periodically update a list of cloud servers that provide a cloud service. The network controller can select a preferred cloud server from the updated list of cloud servers. Upon receiving a client device request to use the cloud service, the network controller can send identifying information of the selected preferred cloud server to the client device.

Methods and systems are described for intelligently steering client devices operating in an enterprise network system to an appropriate access point based on types of traffic on each client device and/or types of traffic on access points. In particular, client devices may be moved to a different access point when the wireless channel provided by a current access point fails to meet the signal strength requirements of latency sensitive traffic utilized by the client device. Client devices may be further steered to new access points based on load conditions on access points. For example, client devices with low priority traffic sessions may be steered away from access points with high traffic load levels. Accordingly, the methods and systems described herein ensure improved network access for latency sensitive access categories and/or access categories that are considered important to an enterprise system with minimal disruptions to these sessions.

Deep packet inspection (DPI) aware client steering and load balancing in wireless local area network (WLAN) infrastructure

In an example, a system is described which includes a centralized controller, a first agent controller, and a second agent controller. The centralized controller executes a routing application to control routing of network traffic across links of a wide area network. The first agent controller is deployed at a branch location of the wide area network to notify the routing application when a host at the branch location requests membership in a multicast group. The second agent controller is deployed at a headend of the wide area network to modify a forwarding rule in response to an instruction from the routing application. The forwarding rule controls an interaction between the headend location and an upstream router to redirect network traffic associated with the multicast group in a manner that joins the host to the multicast group.

Modifications of headend forwarding rules to join wide area network branch hosts to multicast groups

Described herein are techniques for resolving overlapping IP addresses for subnets assigned to uplink interfaces of a network switching device. As an example, a network switching device may determine that an IP address range of a first assigned subnet to a first uplink interface overlaps an IP address range of a second assigned subnet to a second uplink interface. The network switching device may generate a first map between the first assigned subnet and a first intermediate subnet, and generate a second map between the second assigned subnet and a second intermediate subnet, wherein an IP address range of the first intermediate subnet and an IP address range of the second intermediate subnet are non-overlapping.

The present disclosure discloses a method and network device for intelligent handling of voice calls from mobile voice client devices. In some embodiments, the network device detects that a load, corresponding to a plurality of client devices associated with an access point, exceeds a particular threshold value. In some embodiments, the network device detects that a call quality for a current ongoing call, corresponding to a first client device associated with an access point, is below a first threshold value. In response, the network device selects a particular client device, of the plurality of client devices associated with the access point, for disassociation with the access point. The network device then causes the particular client device to disassociate with the access point.

In one embodiment a switch has active and standby LAYER 2 switch interfaces coupled, respectively, to device interfaces of first and second LAYER 2/LAYER 3 network devices. The active switch interface is configured to forward all egress traffic and accept all ingress traffic and the standby switch interface is configured to forward only IGMP messages and configured to block all ingress traffic.
