  • Patent number: 10879584
    Abstract: Access points which can be mounted in a variety of locations or orientations and can support multiple communications protocols are described. The access point includes a main housing, e.g., main body, and a front housing connected together by a hinge. A Wi-Fi antenna is included in the front housing in some embodiments. The access point can be used in an open or closed position. When mounted in a vertical position the front housing can be lowered into a horizontal position facilitating preferred antenna orientation. A first set of cooling fins serves to keep the internal components of the access point off a wall when the access point is wall mounted facilitating air flow. Additional fins act as a spacer between the main housing and the front housing when the access point is used in a closed position facilitating air flow around both sides of the main housing.

  • Patent number: 10880264
    Abstract: A network device may receive an IPv6 packet that includes an IPv6 source address and an IPv6 destination address. The network device may determine, based on the IPv6 packet including an extension header that includes an address prefix option, whether to translate the IPv6 packet into an IPv4 packet. Additionally, based on a determination to translate the IPv6 packet into the IPv4 packet, the network device generates an IPv4 packet that includes an IPv4 source address and an IPv4 destination address. Because the PLAT unit may make the determination whether to translate the IPv6 packet into an IPv4 packet based on the IPv6 packet including the address prefix option instead of based on the IPv6 source address including a customer-translation (CLAT) source prefix, it may be unnecessary to distribute the CLAT source prefix to the network device.

  • Patent number: 10880210
    Abstract: Techniques are disclosed for configuring multiple network devices implementing different protocols or techniques. For example, these techniques allow network devices configured with different protocols to co-exist within the same network, or for the network to seamlessly evolve from one protocol to the other. Techniques described herein provide for an SDN controller that may bridge a network system implementing different protocols, e.g., Open vSwitch Database (OVSDB) and Ethernet Virtual Private Network (EVPN), by translating high-level configuration data (e.g., desired state of the network at a high level of abstraction) that are protocol agnostic to low-level configuration data (e.g., desired state of the network at a low level of abstraction) that are protocol specific. That is, SDN controller may provide management, control, and analytics functions of a virtualized network configured to operate specifically within an OVSDB environment and/or an EVPN environment.

  • Patent number: 10868742
    Abstract: This disclosure describes techniques for monitoring, scheduling, and performance management for virtualization infrastructures within networks. In one example, a computing system includes a plurality of different cloud-based compute clusters (e.g., different cloud projects), each comprising a set of compute nodes. Policy agents execute on the compute nodes to monitor performance and usage metrics relating to resources of the compute nodes. Policy controllers within each cluster deploy policies to the policy agents and evaluate performance and usage metrics from the policy agents by application of one or more rulesets for infrastructure elements of the compute cluster. Each of the policy controllers outputs data to a multi-cluster dashboard software system indicative of a current health status for the infrastructure elements based on the evaluation of the performance and usage metrics for the cluster.

  • Patent number: 10860353
    Abstract: In some embodiments, a non-transitory processor-readable medium includes code to cause a processor to receive, at a management device, an instantiation request for a first virtual machine. The code includes code to cause the processor to identify a first compute device at a first time such that the first compute device is undersubscribed at the first time. The code includes code to cause the processor to send an instruction to instantiate the first virtual machine at the compute device, and receive a signal indicating that a boot process associated with the first virtual machine is complete and that the virtual machine is instantiated at the first compute device. The code includes code to cause the processor to send at a second time, a signal to migrate the first virtual machine from the first compute device to a second compute device in response to the boot process being complete.

  • Patent number: 10863400
    Abstract: Disclosed are methods and systems for improved wireless terminal roaming. In some embodiments, a management module determines access point density metrics for a plurality of centrally managed access points of a communications site. The density metric considers an average RSSI of access point signals received by other access points of the site, and each access point's contribution to the average. A determination of whether a particular wireless terminal roams is based on the density metrics of the source and target access point, as well as statistics relating to a current capacity of each of the access points. The disclosed embodiments may determine that a wireless terminal should transition/roam away from an access point even when that access point's RSSI value at the wireless terminal is above a threshold that would cause traditional methods to inhibit roaming.

  • Patent number: 10862801
    Abstract: A network device may select a candidate entry to remove from a media access control (MAC) table maintained at the network device based on determining that the MAC table is exhausted. The candidate entry may include an identifier for a first virtual local area network (VLAN) associated with the candidate entry. The network device may receive a packet from a source node having a MAC address that does not appear in the MAC table, where the packet may include an identifier for a second VLAN in which the source node is a member. The network device may replace the candidate entry in the MAC table with a new entry corresponding to the source node based on determining that the second VLAN is associated with a greater number of ports than the first VLAN.
