Abstract: A communications system provides a dynamic setting of optimal buffer sizes in IP networks. A method for dynamically adjusting buffer capacities of a router may include steps of monitoring a number of incoming packets to the router, determining a packet arrival rate, and determining the buffer capacities based at least partially on the packet arrival rate. Router buffers are controlled to exhibit the determined buffer capacities, e.g. during writing packets into and reading packets from each of the buffers as part of a packet routing performed by the router. In the disclosed examples, buffer size may be based on the mean arrival rate and one or more of mean packet size and mean waiting time.

Abstract: A device receives, from multiple network elements, status information for a user equipment (UE) connection associated with a wireless core network and updates, based on the status information received from the network elements, a database record for the UE connection. The device receives, from an application server, a request for information associated with the UE connection and constructs, based on the request and from the database record, a resource message that includes real-time information about the UE connection. The device sends the resource message to the application server. The device also provides a disconnect message to the application server and/or the network elements when the status information received from the network elements indicates that the UE has been disconnected from the wireless core network.

Abstract: A network device may handle packet congestion in a network. In one implementation, the network device may receive a packet associated with a quality of service priority class and with a connection to a user device. The network device may include an output queue associated with the priority class of the packet. The output queue may be congested. The network device may determine whether the connection associated with the packet is a guaranteed bit rate connection. The network device may queue the packet according to a first action policy function when the connection associated with the packet is a guaranteed bit rate connection and may queue the packet according to a second action policy function when the connection associated with the packet is not a guaranteed bit rate connection.
