This dissertation focus on the load balancing of signaling gateway, mainly inculde two part : in first part, considered trillium dft architecture, the dissertation presents a scheme suited for signaling gateway, involving software design and implement of m3ua distributed module df and mtp3 distibuted module ldf ; the second part presents the design details of m3ua and mtp3 protocol themselves load balancing mechanism. at the end of this dissertation, a performance test result of based on load balancing signaling gateway are given
本文著重於討論信令網關負載均衡設計與實現，主要分為兩個部分進行闡述，第一部分根據trillium分散式系統架構，提出適合大容量信令網關中ss7和m3ua協議負載均衡的解決方案，並詳細給出m3ua協議側分散式模塊df的軟體設計、實現過程; mtp3協議側分散式模塊ldf的軟體設計，模塊劃分，介面定義，流程圖實現;第二部分提出了m3ua和mtp3協議體內的負載均衡解決方案，並詳細介紹了其設計實現。 -
So at first in this paper, a disk - based xml data storage structure ldf & b based on f & b index is proposed. on one side, ldf & b wipes off the redundancy existing in traditional storage structure which stores the same value information repeatedly ; on the other hand, the index on the tape and the inverted index introduced in this storage structure enable nodes with the same property to be clustered when stored on disk, and enable nodes satisfied with the query to be searched effectively. that is to say, ldf & b can support xml query processing effectively
為此，本文首先提出了一種基於f & b索引的xml數據的磁盤壓縮存儲結構ldf & b ，其優點在於:一方面， ldf & b摒除了傳統存儲方法中相同的值信息重復存儲帶來大量冗餘的問題;另一方面，該結構引入的同帶索引與反向索引結構將具有相同性質的節點聚集在一起，使得可以快速的定位到滿足條件的節點集，很好的支持了其上的查詢處理。
