| 摘 要： | 对于卫星ATM交换系统，星上ATM交换结构的设计是一个非常重要的部分。由于卫星通信具有带宽有限、时延受限、信道误码率高等特点，因而设计星上交换结构时必须尽可能降低交换时延，减少内部阻塞。为此，提出一种基于蚂蚁算法的星上ATM交换结构，并对此方案进行了分析和仿真。结果表明，该结构由于采用了蚂蚁算法和阻塞规避方案，有效改善了信元时延和信元丢失率等性能。

| Abstract: | Satellite communication network is a bandwidth-limited, delay-bounded and high Bit-Error-Rate system, so onboard switching fabric should be improved in order to reduce cell average delay and avoid blocking. This paper presents an onboard ATM switching fabric based on ant algorithm, which can reduce cell average delay and cell loss probability effectively by using ant algorithm and the blocking avoidance method. |

| Keywords: | Onboard switching ATM switching fabric Ant algorithm Blocking avoidance |
