对于接口标识全为0的IPv6地址,标准协议中定义为子网路由器任播地址(Subnet-Router anycast address)。如图3-2所示,subnet prefix是单播IPv6地址前缀,由用户配置单播IPv6地址时指定。 图3-2子网路由器任播地址格式 任播地址不局限于子网路由器任播地址,全球单播地址也可以配置为任播地址。 组播地址(Multicast):用来标识...
IPv6地址按照其传输类型分为三种,即单播地址(UnicastAddress)、组播地址(Multicast Address)和任播地址(Anycast Address)。 组播地址(Multicast)用来标识属于不同节点的一组接口,类似IPv4的组播地址。发送到组播地址的数据包被传输给此地址所标识的所有接口。
特殊地址 组播(Multicast) IPv6 多播(组播)地址是一组接口的标识符(典型在不同节点上)。一个接口可以属于任何数目的多播组。 组播地址最高位前8位固定为全1,也就是“FFXX::/8” #IPv6组播地址构成 IPv6通信的核心大量的使用了组播(邻居发现协议NDP),IPv6不再使用广播。IPv6的任何节点都能够成为一个组播成员...

Anycast树节点多播A new kind of Anycast communication model was proposed on the basis of multicast tree technology.Since this model achieves dynamic Anycast group,it allows Anycast members to freely leave and join Anycast group,it radically solves the existing scalability problem.In addition,this model...

An anycast address is not necessarily a subnet-router anycast address and can also be a global unicast address. Multicastaddress: assigned to a set of interfaces that belong to different nodes and is similar to an IPv4 multicast address. A packet destined for a multicast address is transmitted ...
Multicast address. An identifier for a set of interfaces (typically belonging to different nodes). A packet sent to this address is delivered to all the interfaces identified by the address. The multicast address types supersede the IPv4 broadcast addresses. Anycast address. An identifier for a s...
Multicast address: A packet is delivered to multiple interfaces. Anycast address: A packet is delivered to the nearest of multiple interfaces. The distance between interfaces is defined by the routing cost. IPv6 unicast addresses have the following possible scopes: ...
