【摘要】：基于資源預(yù)留策略提出一種多級光互連仲裁機制,通過將網(wǎng)絡(luò)分級實現(xiàn)快速、高效的仲裁。多優(yōu)先級數(shù)據(jù)緩存隊列的傳輸節(jié)點設(shè)計,提供了不同類型流量的差異化傳輸;通過預(yù)約式兩級仲裁機制,實現(xiàn)網(wǎng)絡(luò)的完全公平與100%的高吞吐率。設(shè)計并對快速仲裁通道進行了合理布局,極大地縮短了仲裁延遲。仿真結(jié)果表明:采用基于資源預(yù)留的分級仲裁策略,在多種流量模式下所有節(jié)點均獲得公平的服務(wù)。與Feather Weight相比,分級仲裁策略吞吐率提高17%;與2-pass相比,仲裁延遲減少15%,同時,功耗減少5%。
[Abstract]:A multilevel optical interconnection arbitration mechanism based on resource reservation strategy is proposed to achieve fast and efficient arbitration by grading the network. The transport node design of multi-priority data cache queue provides different traffic differential transmission, and realizes the network completely fair and 100% high throughput through the reservation two-level arbitration mechanism. The reasonable layout of the fast arbitration channel is designed and the arbitration delay is greatly shortened. The simulation results show that the hierarchical arbitration strategy based on resource reservation can provide fair service to all nodes in various traffic modes. Compared with Feather Weight, the throughput of hierarchical arbitration strategy is increased by 17. Compared with 2-pass, arbitration delay is reduced by 15 and power consumption is reduced by 5.
