  1. Based on the above - mentioned situation, it is therefore suggested that the fixed telecom network company will focus on how to add voice service on ip man, and to increase value added service, i. e. to develop the pure sip packet voice on the broadband man, and to boundle instant messageand user presence business ; to promote mgcph. 248 mode and sip mode on the newly established community using broadband lan access ; the big media gateway in the soft switching will mainly suitable for the broadband ip man voice service and pstn interconnection

    根據以上情況的分析，建議固定網路電信公司將發展的重點放在如何在寬帶ip城域網上增加話音業務，提高增值收入方面。即在寬帶城域網上發展純sip分組話音方式，綁定即時消息和用戶狀態（ presence ）業務;在新建寬帶lan接入小區推廣mgcph . 248話機和sip話機方式；軟交換中大媒體網關方式主要用作寬帶ip城域網上話音業務與pstn互通方面。
  2. We firstly study some aspects, such as the modulation ( ofdm ) in the physical layer and the media access control ( mac ) protocols, combining reliable data transmission with high - throughput access methods and real - time, quality - of - service ( qos ) features. some problems exist in tcp applications over plc, because the high bit error rate makes it difficult to estimate the round trip time ( rtt ) and causes unnecessary retransmission

    通過對現有的兩種產品（ homeplug和inari ）的mac協議：類似無線通訊csma ca協議（以競爭為基礎）和集中式的令牌環（ ctp ）協議（避免競爭）的媒質接入控制的原理進行分析和計算，對兩個協議進行了性能評價及分析了它們對qos的支持。
  3. Proximity access enables broadband users to access a nearby cache when they want to access the cache content of a specific stream media service or that deployed by the cdn to a remote node. that is to say, it directs user access to a relatively near cache that operates normally so that the user can be served directly by an edge cache. this allows the saving of bandwidth and alleviation of pressure on the core server as well as the acceleration of the access to medium and high speed stream media

    實現寬帶用戶在訪問特定的一些流媒體服務或者是已經被cdn部署到邊緣節點上的cache內容時，能夠就近訪問cache ，也就是能把用戶的訪問定向到離用戶比較近而且運轉正常的cache上去，由邊緣的cache直接為用戶提供服務，從而做到節省帶寬和減輕對核心服務器的壓力，以及加速對中、高速流媒體的訪問。
  4. Provides various narrow and broadband access. it consists of broadband lan access equipment, adsl equipment, narrow band access equipment, broadband atm multipal service access wuipment, media gateway equipment, fibre, type five and wisted cable, etc

    提供各種寬、窄帶業務的接入，由寬帶lan接入設備、 adsl設備、窄帶接入網設備、寬帶atm多業務接入設備、媒體網關設備、光纖、五類線、雙絞線等組成。
  5. Information technology. international standardized profile rb. relaying the connection - mode network service. psdn subnetwork - dependent media - dependent requirements for virtual calls over a permanent access

    信息技術.國際標準化數據區rb .中繼連接模式網路服務.經永久性通路的虛擬呼叫的psdn子網路介質依賴要求
  6. Being an layer 2 protocol used for media access control, resilient packet ring ( rpr ) does not only inherit the economy advantage of ethernet, administration and reliability advantages of sdh, but also introduces its unique characteristics, such as fairness access, topology discovery, guaranteed quality of service, which make it possible to optimize the transport of data packet the application of rpr technology in the sdh - based mstp can make full use of both the advantages of sdh and rpr in tdm and data service

    Rpr技術是一種二層mac協議，它繼承了以太網帶寬提供的成本優勢和sdh的可管理性、網路的生存性等方面的優勢，還增加了業務的公平接入能力、拓撲發現能力、 qos保證能力等特色，優化了ip分組數據業務的傳送方式。 rpr技術和sdh技術相結合，使sdh設備在能有效地傳送tdm業務的同時，對于基於ip的分組數據的傳送也得到了優化，使之成為新一代的多業務傳輸平臺。
  7. A digital certificate brings you extra security and protects you from unauthorized access to your account ( s ). you can login the e - banking service using a digital certificate on diskette, smart id card or any other storage media
