ホロニック光情報ネットワークにおけるマルチメディア統合スイッチング方式

在本研究中，为了实现全息光信息网络中的多媒体集成交换方案，我们确定了以下三个目标，并为此进行了研究。1.在波分复用和时分复用技术并存的波段路由网络中，必须建立对业务需求变化具有鲁棒性的波段路径设计方法。2.在保证QoS的缓冲管理方案的硬件设计上，必须建立对可变长度数据包到达和多个输出端口共享一个缓冲存储器的功能扩展，以及其更高的速度运行。3.通过连接agent网关及其原型网络，在逻辑网络中建立移动agent迁移规则。至于1。提出了一种新的路径设计方法，该方法引入了带宽单元全单元和半单元的概念，可以根据需求变化灵活地改变波段路径的带宽，并通过性能评价验证了其有效性。至于2。对缓冲区管理方案进行硬件设计，区分各流，提高QoS，为各流分配理想的缓冲区容量，根据Push-out机制丢弃到达的数据包，并将其与数据包传输调度相关联。利用硬件描述语言VHDL对其进行了编程，并对其进行了实际合成。因此，我们采用0.18 μm CMOS技术获得了约135MHz行为和47K门的规格。即使非常短的控制数据包连续到达目标缓冲区，我们的规范也可以达到11.5Gbps的吞吐量。作为。为3。提出了移动代理迁移和复制原则，以实现每个作业未完成工作的公平性。它适用于某一作业的移动代理并发迁移的网络环境，在代理-网关逻辑网络上进行复制，以控制全息光信息网络。这个原型实际上是由java语言构造的。少

In this research, to realize the multimedia-integrated switching scheme in the Holonic optical information network, we established the following three objectives, and studied for these purposes. 1.Under the waveband routing network with both WDM and TDM technologies, waveband path design method which is robust to the variation of traffic demand must be established. 2.As for the hardware design of the buffer management scheme to guarantee the QoS, functional extension to the variable length packet arrival and multiple output ports sharing a buffer memory, and its higher speed operation must be established. 3.Mobile agent migration discipline in the logical network by connecting agent gateways and its prototype network must be established.As for 1., we proposed new path design method which introduces the concept of the bandwidth unit Full Unit and Half Unit and enables the bandwidth change of the waveband paths flexibly according to the demand variation and confirmed its effectiveness th … More rough the performance evaluation. As for 2., We designed the hardware of the buffer management scheme to differentiate each flow and improve the QoS, which assigns each flow the ideally allocated buffer volume, discards arrival packets based on the Push-out mechanism, and associates them with the packet transfer scheduling. Also, we programmed it by the hardware description language, VHDL and synthesized it actually. As a result, we obtained the specification of about 135MHz behavior and 47K gates by using 0.18 μm CMOS technology. Even if very short control packets continuously arrives at the target buffer, our specification can attain the throughput of 11.5Gbps. As. for 3., we proposed the mobile agent migration and replication discipline to realize the fairness of the unfinished work per each job. This is applied to the network environment where mobile agent of a certain job concurrently migrates making its replication on the agent-gateway logical network to control the Holonic optical information network. This prototype is actually constructed by the java language. Less
