Abstract

Abstract:

Some basic requirements of IP address management (IPAM) in large-scale IPv4/IPv6 transition environment in campus wired LAN and WLAN is summarized,and analyzes some special technologies of IPv6 address management as well as some operating key technologies of IPAM service in such environment.Finally,a real deployment of IPAM service in such a large-scale IPv4/IPv6 transition environment is introduced.Experience of unified IPAM service oriented next-generation wired LAN and WLAN are gathered.

Key words: large-scale, IPv4/IPv6, transition, unified, address management

DHCPv6消息	描述	等效DHCP消息
要求（solicit）	由客户端发送以定位服务器	DHCPDiscover
公告（advertise）	由服务器对“要求”消息进行响应时发送以指明可用性	DHCPOffer
请求（request）	由客户端发送以请求来自特定服务器的地址或配置设置	DHCPRequest
确认（confirm）	由客户端发送给所有服务器，以确定对于已连接的链接客户端的配置是否有效	DHCPRequest
更新（renew）	由客户端发送给特定服务器以延长分配地址的生存期并获取更新的配置设置	DHCPRequest
重新绑定（rebind）	未接收到对“更新”消息的响应时由客户端发送给任何服务器	DHCPRequest
应答（reply）	对要求、请求、更新、重新绑定、信息请求、确认、发布或拒绝消息进行响应时由服务器发送给特定客户端	DHCPAck
发布（release）	由客户端发送以指明客户端不再使用分配的地址	DHCPRelease
拒绝（decline）	由客户端发送给特定服务器以指明分配的地址已在使用	DHCPDecline
重新配置（reconfigure）	由服务器发送给客户端以指明该服务器具有新的或更新的配置设置。客户端随后发送“更新”或“信息请求”消息	N/A
信息请求（information-request）	由客户端发送以请求配置设置（但不包括地址）	DHCPInform
中继转发	由中继代理发送以转发消息给服务器。中继转发包含封装为 DHCPv6 中继消息	N/A
（relay forw）	选项的客户端消息
中继应答	由服务器发送以通过中继代理发送消息给客户端。中继应答包含封装为	N/A
（relay reply）	DHCPv6 中继消息选项的服务器消息
