摘要： A communication system having a source node, at least one mobile node, and a router that transmits data packets transmitted from the source node to a corresponding one of the at least one mobile node and multiplexes response signals to the data packets received from the corresponding one of the at least one mobile node to transmit the multiplexed response signals to the source node. The communication system includes: a link monitoring unit which calculates a capacity of a wireless link between the router and the corresponding one of the at least one mobile node; and a congestion control and adjustment unit which adjusts window field values in the response signals according to the calculated capacity. The router transmits the response signals, the response signals including the adjusted window field values to the source node, and the source node sequentially transmits the data packets on the basis of the adjusted window field values.

摘要： A queue management method of an access network device includes receiving a packet, determining feasibility of a packet transmission within a delivery deadline allowed from a destination if the received packet is for real-time transmission, storing the packet in the transmission queue and transmitting the packet in sequential order of the storage when the packet transmission within the delivery deadline is feasible, and dropping the packet instead of storing the packet in the transmission queue when the packet transmission is determined infeasible. Accordingly, resources required for the packet transmission are saved.

摘要： A method, medium, and system for reserving resources in a mobile network. A mobile node reports a start of a handover to a present access router if the handover of the mobile node occurs, and the previous access router transmits specified session information to a candidate access router that has a possibility handling the mobile node's handover. A candidate crossover router, which performs a resource reservation work on a new path and a resource release on the previous path, is searched, and a localized resource reservation is established by exchanging a specified resource reservation message before the handover is completed if the candidate crossover router is determined. Accordingly, duplication of resources can be prevented, and a prompt resource reservation can be achieved during the handover.
