[0009] "Signal Processing", Volume 25, Issue 8, 2009, "Threshold-Based Handover Priority Resource Management Mechanism in LEO Satellite Networks" proposes a threshold-based handover priority resource management algorithm for LEO satellite networks. Before actual system configuration According to the system parameters and business parameters, the size of the reserved threshold value should be calculated to dynamically reflect the changes of business and system parameters, but this method does not compare the reserved parameters applied for with the actually used parameters

specific Embodiment

[0083] According to different IP service characteristics and satellite IP network status, the settings of IP service window threshold L, on-board alarm feedback validity period T and IP service sending window W are different. Here we take the video conferencing based on satellite access as an example, the transmission bandwidth generally ranges from 64kbit / s to 2Mbit / s, the on-board IP service window threshold L is set to 10%; The business window W is set to 60min. Adopt the concrete processing step of the present invention as follows:

[0084] (1) The ground terminal sets the resource reservation parameters according to the IP service requirements, the application reserved bandwidth is 1.2Mbps, the validity period T of the on-board alarm feedback is 6min, the IP service window threshold L is 10%, and the IP service sending window W is 60min. Go to step (2);

[0085] (2) The ground terminal generates a path message according to the set parameters (see Table 1 message type ①)...

Abstract

A method for reserving satellite IP resources based on a dynamic window. The resource reservation method is used to reserve the required resources for IP services in advance during satellite-to-earth communication. When the ratio of the absolute value to the actual resources used exceeds the IP service window, an on-board alarm feedback is generated to provide feedback on the resources actually used on the star. The IP service window can be dynamically adjusted according to the type of IP service sent. Feedback, reset the resource reservation parameters of the IP service application. This method can dynamically adjust the reserved resource parameters and IP service transmission time, so that the value of resources used by RSVP matches the value of resources actually used by IP services, and the time of resources used by RSVP matches the time of resources actually used by IP services, thus ensuring It meets the QoS requirements of IP services in the satellite IP network, and improves the resource utilization of the satellite network.

Description

technical field [0001] The invention relates to a dynamic window-based satellite IP resource reservation processing method, which belongs to the field of satellite communication. Background technique [0002] IP provides a connectionless, unreliable, and unacknowledged datagram delivery mechanism, which cannot guarantee service quality (QoS, Quality of Service) while effectively utilizing network resources. Resource Reservation Protocol (RSVP, ResourceReServation Protocol) is a signaling mechanism carried on IP, which can be used to establish a unidirectional channel with sufficient bandwidth for data flow in the network, so as to realize the predictability of data flow transmission. The resource reservation mechanism includes a signaling call establishment process. During the call establishment process, the user requests bandwidth and QoS parameters, and the routers participating in the resource reservation process in the network will respond whether they have enough resou...
