“…The method of sharing cache among multiple users on board can better solve the above problems, and the onboard shared buffer switch may be the best payload architecture in terms of performance and interoperability with current and future protocols and QoS mechanisms. 12 Because of the limited onboard resources and flexible design and use of LEO hopping beam communication, this paper designs an IP packet dual-linked list data exchange structure based on user data management to realize the sharing of data storage space. As shown in Figure 2 below, the double linked list is user management linked list A and shared data cache linked list B.…”

“…Therefore, the practice of preallocating fixed cache space according to the total number of users of the system requires huge cache space, which conflicts with the limited satellite resources. The method of sharing cache among multiple users on board can better solve the above problems, and the onboard shared buffer switch may be the best payload architecture in terms of performance and interoperability with current and future protocols and QoS mechanisms 12 …”

SummaryThe beam‐hopping technology can solve the problems of uneven user distribution and uneven service demand and improve the efficiency of resource utilization. It is one of the important technologies of future satellite–ground integrated communication. However, the mobility of LEO satellites and the on‐demand scheduling of beams make each satellite beam correspond to multiple ground wave positions, which brings great difficulties to data processing. In this paper, after analyzing the difficulties of the data forwarding buffer of the beam‐hopping system, a double‐linked list structure of user state chain and data buffer chain is proposed, which solves the problem of data forwarding between the satellite and users in the dynamic state and provides an efficient solution for the data exchange of the beam‐hopping LEO satellite.

Korean military is developing the next generation military satellite communications system in order to achieve the requirements of future military satellite communication such as high speed, high capacity, survivability, all IP networking, and on-the-move. In this paper, we survey and analyze the research interests about optimal resource allocation and IP networking such as MF-TDMA, random access, satellite IP routing, and PEP. Conventional researches have focused on the increase in channel throughput and efficiency. In addition to these measurements, we consider heterogeneous satellite terminals, full mesh topology, distributed network, anti-jamming, and the like which are the special characteristics of the next generation military satellite communications system. Based on this, we present key research issues and evaluation on the issues by simulation.
