Mobile IP has been designed within the IETF to serve the needs of the burgeoning population of mobile computer users who wish to connect to the Internet and maintain communications as they move from place to place. The basic protocol is described, with details given on the three major component protocols: Agent Advertisement, Registration and Tunnelling. Route optimization procedures are then outlined and further topics of current interest are described. © 1998 John Wiley & Sons, Ltd. 相似文献

我国电信业对NGN标准的研究应该说起步不晚,但是为什么自主创新的核心技术仍然比较缺乏?从国际电信业各标准组织的全面认识和分析出发,指出我国NGN标准的参与还停留在传统的、依赖政府力量的话语权阶段,对一些面向市场驱动的基础和创新技术标准组织的形式和风格还比较陌生。通过分析指出,伴随着IP应用和技术的高速发展及其对电信产业的全方位影响,IETF将在电信NGN的技术体系中承担起越来越重要的、创造基础技术的支柱性角色。在过去的相当长时间里,我国电信业对IETF的不熟悉和低参与率的现状,不仅不利于我国电信自主创新技术的产生,更为重要的是使我国丧失了学习和了解国际上观念创新的机遇,错过了参与和掌握技术创新的主体舞台。 相似文献

The challenge to provide seamless mobility in the near future emerges as a key topic in various standardization bodies. This
includes first of all the support of seamless handover between homogeneous networks. Distinct technologies—such as IEEE 802.11WLANs
(Wi-Fi) and IEEE 802.16 MANs WiMAX—have recently augmented such support to existing standards to enable seamless homogeneous
handover. Cellular networks, in contrast, already included this inherently from the start. Currently considerable effort goes
into coupling of different radio access technologies. Therefore, the second key topic in standardization is seamless heterogeneous
handovers. IEEE, IETF, as well as 3GPP consider different approaches toward architectures and protocols enabling seamless
mobility management. In this work, we discuss recent and on-going standardization activities within IEEE, IETF, and 3GPP toward
seamless homogeneous as well as heterogeneous mobility support. 相似文献
