Abstract: Protocol-Independent Multicast (PIM) uses PIM hello messages to maintain neighborship information. PIM may be implemented in an Ethernet VPN (EVPN) providing Optimized Inter-Subnet Multicast (OISM). Techniques are disclosed for improving PIM neighborship efficiency and speed in an EVPN. An Inclusive Multicast Ethernet Tag (IMET) may be used to set PIM neighborship instead of using PIM hello messages and TCP may be used to determine if the neighbor is disconnected instead of tracking PIM timers.

Abstract: A testing system and method for testing application code against various failure scenarios. The testing system and method generate a test workflow including test source code implementing a series of actions that affect an application component and or an infrastructure component included in application code. The testing system and method execute the test workflow to determine the performance of the application code during one or more failure scenarios caused by the series of actions included in the test workflow. Performance data generated by the test code is analyzed by a performance analysis service or method to identify limitations of the application code and build resiliency patterns that address the limitations and improve the performance of the application code.

Abstract: Peer devices in a peer group of provider edge devices to which a customer edge device is multi-homed, advertise Selective Multicast Ethernet Tag (SMET) routes to other peer devices on a core to receive traffic addressed to a multicast group. The peer devices in the peer group advertise the SMET routes irrespective of whether they are the designated forwarder or not. A peer device receiving traffic for the multicast group will drop the packet if it is not the designated forwarder and will forward the packet if it is the designated forwarder.

Abstract: AP's associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP's with which to communicate. A system coordinator causes the AP's to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP's make the selection for it. In a 1st technique, multiple AP's share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a “personal cell”. In a 2nd technique, AP's each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device's identifier, thus appearing to wireless devices as a “personal AP”.

Abstract: For seamless mobility, at least one communication parameter to associate with a BSSID is selected. A beacon is sent from a first access point to advertise its presence, wherein the beacon comprises the BSSID associated with the at least one communication parameter. Responsive to the mobile station choosing the BSSID being advertised in the beacon sent from the first access point, a uniquely assign the BSSID is selected for a mobile station. The first access point from the plurality of access points is associated with the mobile station persistently. Associating is made as selected by the system coordinator, the uniquely assigned BSSID being independent of an identify of mobile station and being eligible for subsequent assignment to a different mobile station as determined by the system coordinator.

Abstract: A system and method enable the transmission of messages between a source device and a wireless station. A first message is received at an access point from the source device. The access point transmits the first message to the wireless station and stores a copy of the first message in a memory. The access point receives an acknowledgement message from the wireless station and transmits a proxy acknowledgement message to the source device. The access point transmits a control message to the source device to limit the number or size of additional messages sent from the source device based on a number or size of messages currently stored in the memory and a maximum number or size of messages that can be stored in the memory.
