Abstract: In a wireless base station device, a PDCP buffer unit temporarily stores data sent from a core network device for the purpose of sending the data to a mobile station device. A data measurement unit measures the volume of data stored in a PDCP buffer unit. On the basis of a measurement value of the data volume measured by the data measurement unit, the congestion state determination unit determines whether or not the PDCP buffer unit is in a congestion state. In the core network device, a sending data storage unit stores data to be sent to the wireless base station device. On the basis of a result of the determination by the congestion state determination unit, a transmission/reception unit sends the data stored in the sending data storage unit to the wireless base station device. In this way, loss of data communicated between the communication devices is reduced.

Abstract: A mechanism for identifying long-lived large flows in a communication network is disclosed in which packets transmitted through ports of a switching device or router are continuously examined. As new flows are recognized, their flow definition information is processed through a hashing table that uses a predetermined number of hash stages each having a pre-selected number of hash buckets.

At the same time as counters are incremented, they are compared against a threshold number. If the bucket counters for all the hash stages exceed this threshold number, the flow is identified as a long-lived large flow and stored as such in a flow table.
