This paper briefly describes the extension of point - to - point communication link to node - connected communication network and of multiplex to multi - access technologies
摘要概述了從點點線路至結點聯成通信網和從多路技術至多址技術的發展過程，解釋了光纖通信網發掘利用潛在容量以及建立未來高速通信網的關鍵問題。 -
The research job includes bringing a project about fault calculation, using node impedance matrix as maths model of network to derive the arithmetic based on the fundamental of modifying impedance matrix by adding the branch, building the whole database with micosoft access. the whole project is realized with visual c + + 6. 0. it is applied to au hui electric network, and is proved correct
本文首先根據系統的要求，綜合考慮各種運行方式變化，提出合理的零序電流，分支系數的計算方案；然後採用節點阻抗矩陣作為系統的數學模型，推導出基於支路追加法的阻抗矩陣快速補償優化演算法，從而實現計算方案；最後以micosoftaccess為工具設計出完整的故障計算數據庫。 -
When there is a backbone ip network in the province, the gsn, a generic term for both the sgsn and the ggsn, can serve as an access node to the backbone ip network
當省內有ip骨幹網路時， gsn （ gprs服務節點與關口節點的統稱）節點作為ip骨幹網的接入節點。 -
The subsystem number ( ssn ) is a number that identifies which application to access on a specific network node
子系統號（ ssn ）是識別在特定網路節點要訪問哪個應用程序的一個號碼。 -
Technical requirements for access network - multi - service access node
接入網技術要求?綜合接入系統 -
High capacity bandwidth cross - management equipment is a new type of network element, which can integrate all the access and transfer facilities into a single network node
大容量帶寬交叉管理設備是一種新型的網路單元，它可以把所有的接入設施和傳送設施綜合在單一的網路節點內。 -
Specifically, for the first time all factors impairing tcp performance are identified based on network protocol hierarchy, i. e., lossy wireless channel at the physical layer ; excessive contention and unfair access at the mac layer ; frail routing protocol at the network layer, the mac layer and the network layer related mobile node ; unfit congestion window size at the transport layer and the transport layer related asymmetric path
Tcp是一種面向連接的可靠傳輸層協議，最初是針對有線網路設計的。由於有線網路鏈路可靠性高，傳統tcp認為丟包和亂序是由網路擁塞所導致。然而，在manets中，眾多非擁塞因素導致了丟包和亂序。 -
An on - demand synchronization code division multiple access odscdma protocol for the mobile ad hoc network was proposed. the protocol established the temporary synchronization between the sending node and receiving node only when they are communicating.
協議僅在通信時在收發節點間建立臨時的同步，綜合了同步與異步mac協議的優點，通過時隙預留，功率控制和cdma技術來提高網路的性能。 -
In order to win the time for avoiding or decreasing the communication interrupt and latency caused by movement, the model aims to predict the movement direction of the mobile node in mobile ip network and the access router which the mobile node is going to attach to
該模型用於預測移動ip網路中移動節點的運動方向和將要連接的接入路由器，為避免或減小由於移動造成的通信中斷和時延贏得準備時間。 -
For a small local network, the gsn node can be located in the exchange room. the pcu is connected to the sgsn on a ppp basis so as to save trunks. when there are many pcus and they are located in places other than the exchange, they can access to the sgsn via the existing fr network or a self - built fr network
對于規模較小的本地網，可將gsn節點設置在交換機房內，其pcu經過交換機以ppp的方式同sgsn連接，可以節省中繼線路。當pcu單元數量多且與交換機位於不同的地方時，可以通過現有的fr網或自己組建fr網路接入到sgsn中，此時gsn節點位置相對靈活。 -
Based on the idea of contention reservation access and polling transmission, user - dependent perfect - scheduling multiple access ( upma ) protocol is presented, which supports both node mobility and multi - hop network architecture. it improves channel utilization greatly and guarantees that a node accesses the channel rapidly
基於有效競爭預約接入、無沖突輪詢傳輸的思想提出了在無線adhoc網路中支持節點移動性和多跳網路結構的依據用戶妥善安排的多址接入（ upma ）協議。 -
In this thesis, the components of the computing pool are designed based on globus platform. the service use ldap ( lightweight directory access protocol ) to realize the effective management, monitoring and control of the resources in the computing pool. the monitored information includes the cpu utilization rate, the free memory and the network status of the current node, . etc
論文所設計的計算池管理組件主要負責基於globus網格計算平臺，應用ldap （ lightweightdirectoryaccessprotocol ）實現對計算池資源的有效管理和監控，監控信息包括當前節點的cpu利用率、剩餘內存以及網路狀況等等。
