內(nèi) 容 摘 要

 隨著互聯(lián)網(wǎng)絡(luò)的飛速發(fā)展,網(wǎng)絡(luò)傳輸速度越來越慢,網(wǎng)絡(luò)服務(wù)質(zhì)量成為人們的關(guān)注點(diǎn). 在信息化社會(huì)中，人們對(duì)計(jì)算機(jī)網(wǎng)絡(luò)的依賴日益增強(qiáng)。越來越多的信息和重要數(shù)據(jù)資源存儲(chǔ)和傳輸于網(wǎng)絡(luò)中，通過網(wǎng)絡(luò)獲取和交換信息的方式已成為當(dāng)前主要的信息溝通方式之一。本文先介紹了 QoS 的意義及背景，再說明了效率機(jī)制和關(guān)鍵指標(biāo)，其次介紹了改善流媒體傳輸質(zhì)量的因素和方法，最后說明了QoS技術(shù)在網(wǎng)絡(luò)中的應(yīng)用和發(fā)展。網(wǎng)絡(luò)傳輸質(zhì)量在我們社會(huì)生活中占據(jù)很重要的作用，我們要重視起來。

Abstract

 The clauses jeopardizing the interests of the counterpart commonly exist in the format contract. Depending on the absolutely dominating economic or legal status, the user of the format contract makes the clause ignoring the possibility of negotiation between both sides. Therefore, this kind of clause is vividly called the “overlord’s clause”. The existence of the “overlord’s clause” influences the stability of social economic order to a certain extent, violates the equitable principle and furthermore, goes against the building of a harmonious society.  The article studies the using system, the using measures as well as the making procedure of the format contract, and explores the managing method of it from a few sides so as to eradicate the “overlord’s clause”, nip its appearance in the bud and realize social justice and righteousness.

  

Key words: format contract, overlord’s clause, legal system
