Network Working Group G. Bajko Request for Comments: 5678 Nokia Category: Standards Track S. Das Telcordia Technologies Inc. December 2009 Dynamic Host Configuration Protocol (DHCPv4 and DHCPv6) Options for IEEE 802.21 Mobility Services (MoS) Discovery Abstract This document defines new Dynamic Host Configuration Protocol (DHCPv4 and DHCPv6) options that contain a list of IP addresses and a list of domain names that can be mapped to servers providing IEEE 802.21 type of Mobility Service (MoS) (see RFC 5677). These Mobility Services are used to assist a mobile node (MN) in handover preparation (network discovery) and handover decision (network selection). The services addressed in this document are the Media Independent Handover Services defined in IEEE 802.21. Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.

Introduction IEEE 802.21 [IEEE802.21] defines three distinct service types to facilitate link layer handovers across heterogeneous technologies: a) Information Services (IS) IS provides a unified framework to the higher-layer entities across the heterogeneous network environment to facilitate discovery and selection of multiple types of networks existing within a geographical area. The objective is to help the higher- layer mobility protocols acquire a global view of heterogeneous networks and perform seamless handover across these networks. b) Event Services (ES) Events may indicate changes in state and transmission behavior of the physical, data link, and logical link layers, or predict state changes of these layers. The Event Service may also be used to indicate management actions or command status on the part of the network or some management entity. c) Command Services (CS) The command service enables higher layers to control the physical, data link, and logical link layers. The higher layers may control the reconfiguration or selection of an appropriate link through a set of handover commands. Bajko & Das Standards Track [Page 2] RFC 5678 Mobility Services for DCHP Options December 2009 In IEEE terminology, these services are called Media Independent Handover (MIH) services. While these services may be co-located, the different pattern and type of information they provide do notShow full document text
