    摘要： Methods and systems are provided for routing or forwarding packet data conforming to two different communication protocols simultaneously in a computer network. The first protocol may be a legacy protocol, such as IPv4, with routing being performed in a manner that maintains legacy behavior and functions. Such functions may include network address translation. The second protocol may be a newer protocol, such as IPv6, with the routing or forwarding being performed through reduced complexity bridging that enables simplified connectivity of second protocol devices. The bridging performed typically requires less memory and processing power than traditional routing techniques such as those implemented for the first protocol. Reduced memory and processing power requirements enable the second protocol routing functions to be added to legacy equipment that would not otherwise be able to support routing of the second protocol packet data.

    摘要翻译： 提供方法和系统用于在计算机网络中同时路由或转发符合两个不同通信协议的分组数据。 第一协议可以是诸如IPv4的传统协议，其中路由以维护传统行为和功能的方式执行。 这样的功能可以包括网络地址转换。 第二协议可以是诸如IPv6的较新协议，其中通过减少复杂度桥接来执行路由或转发，从而实现第二协议设备的简化连接。 执行的桥接通常比传统路由技术（例如为第一协议实现的那些技术）需要较少的存储器和处理能力。 减少的存储器和处理能力要求使得能够将第二协议路由功能添加到传统设备，否则将不能支持第二协议分组数据的路由。

    摘要： A method that incorporates teachings of the subject disclosure may include, for example, transmitting a first query to a domain naming server responsive to receiving a session initiation protocol message comprising a fully qualified domain name. The first query can include one of an internet protocol version 4 address query or an internet protocol version 6 address query associated with the fully qualified domain name. The method can include receiving at least one answer from the domain naming server. The at least one answer can include at least one of an internet protocol version 4 address having no errors, a second internet protocol version 6 address having no errors, or both. The method can also include transmitting a message to a communication device. The message can include information associated with the at least one answer.

    摘要： In a method for addressing messages in a computer network in which two different types of address are used, wherein at least one first network element (4, 5, 6, 7, 8) uses exclusively a first type of address, at least one second network element (14, 15, 16, 17, 18) uses exclusively a second type of address and at least one third network element (9, 10, 11, 12, 13, 14) uses both types of address, at least one third network element (9) is a communication terminal which, besides its function as a communication terminal, also performs a function as an address converter for messages for which said communication terminal is neither the original sender nor an ultimate recipient.

    摘要： The embodiments of the present invention provide a method, a device, and a system for forwarding a packet. The method includes: receiving an IPv6 packet sent by a gateway, and obtaining a flow label of the IPv6 packet, where the flow label of the IPv6 packet is corresponding to a link identity of customer premise equipment in one-to-one correspondence; decapsulating the IPv6 packet; performing network address translation on a decapsulated packet according to the flow label; and forwarding the decapsulated packet according to a translated network address. When multiple links between the gateway and an AFTR are corresponding to the same tunnel for network address translation, in the case that IP addresses of terminal users are overlapping or are the same, different terminal users can be distinguished, so that a terminal user that sends a packet can receive feedback, thus improving customer satisfaction.
