摘要： A configuration method of a cryptographically generated address (CGA) is disclosed. The configuration method is used to enable a generated CGA to satisfy requirements of a network configuration, and includes the following steps. A Dynamic Host Configuration Protocol (DHCP) server receives a client configuration information sent from a client. The DHCP server generates a CGA according to the client configuration and the network configuration from the DHCP server. The DHCP server delivers the CGA to the client. The network configuration is made as a reference when the CGA is generated, which overcomes a disadvantage that the CGA generated by the client cannot satisfy the requirements of the network configuration in the prior art. Thus, the generation of CGA can be intervened at a network management level, and a management capability of the network is improved.
摘要翻译：公开了一种加密生成地址（CGA）的配置方法。配置方法用于使生成的CGA能够满足网络配置的要求，并包括以下步骤。动态主机配置协议（DHCP）服务器接收客户端发送的客户端配置信息。 DHCP服务器根据客户端配置和DHCP服务器的网络配置生成CGA。 DHCP服务器将CGA提供给客户端。当生成CGA时，将网络配置作为参考，克服了客户端生成的CGA不能满足现有技术中的网络配置的要求的缺点。因此，CGA的生成可以在网络管理层进行干预，提高网络的管理能力。

摘要： A method for transferring an IP transmission session is disclosed, including the following: a transmission session is created between the first node and second node based on a single IP protocol; the first node and second node obtain a transferable address pair by exchanging the session transfer management signaling; the transferable address pair is checked for bidirectional reachability; the transferable address pair is available if reachable in both directions, or is not available if unreachable in either direction; and the transmission session is transferred through the available transferable address pair. An apparatus for transferring an IP transmission session is also disclosed. Through the technical solution under the present invention, a session can be transferred in a network where IPv4 coexists with IPv6 without affecting continuity of the end-to-end transmission session, thus fulfilling the requirements in the transition period during which IPv4 coexists with IPv6.

摘要： A method, an apparatus, and a system for configuring a key are provided. The method includes the following steps. A mobile node (MN) and an authentication authorization accounting home server (AAAH) generate a visited domain specific root key (DSRK) respectively. The AAAH sends the DSRK to an AAA server in a visited domian (AAAV). The MN and the AAAV generate a visited domain media independent handover service root key (DS-MIHS-RK) by using the DSRK respectively. The AAAV sends the DS-MIHS-RK to a visited domain media independent handover (MIH) authenticator. Thus, cumbersomeness and risks of errors in configuring and authenticating a password manually are avoided, so that large-scale and secure deployment of the MIH service becomes possible.
