Abstract: A provider edge (PE) device may receive an indication to perform a designated forwarder (DF) election associated with a network segment that includes the PE device, one or more other PE devices, and a client edge (CE) device. The PE device, the one or more other PE devices, and the CE device may be associated with an Ethernet virtual private network (EVPN) that includes a group of EVPN instances (EVIs). The PE device may perform the DF election in order to determine election information associated with the PE device. The election information may include information associated with a particular EVI, of the group of EVIs, for which the PE device is to act as a DF. The PE device may provide the election information to the CE device to cause the CE device to provide traffic, associated with a particular VLAN included in the particular EVI, to the PE device.

Abstract: A system is configured to: transmit requests to a first device and a second device; receive a first reply from the first device in response to one of the requests; determine an address of the first device based on the first reply; assign a first port to a first network when the first device is a first one of one or more devices that replied to the requests and have a same address as the first device; receive a second reply from the second device in response to another one of the requests; assign a second port to a second network when the address of the second device is the same as the address of the first device; and reassign the second port, from the second network, to the first network when a failure of the first device occurs.

Abstract: A call handling system receives an asynchronous call request, from a call requester, requesting performance of an operation, where the call request includes a delay parameter specified by the call requester. The call handling system performs the requested operation, and sends a callback to the call requester, which includes partial results from performance of the requested operation, at selected intervals determined by the delay parameter.
