摘要： Wireless sensor platforms (10), when deployed, can ascertain whether they can meaningfully participate in communications with more than one cluster (22, 23) of such devices. When true, such multi-cluster platforms can serve as bridge nodes to facilitate the passing of data collected from one cluster to or through another cluster. In a preferred embodiment, the platforms serving as bridge modes (24 and 25) utilize a communication schedule that imposes no greater work load than the load the platform would otherwise have served as an ordinary node, and preferably the workload is considerably reduced. This aids in ensuring that the portable power reserves of the bridge nodes will support bridge operations for at least as long as the clusters are otherwise functioning.

摘要： A dual-stack host (430) is provided on a multicast network (470) using first and second protocols (450, 460). The dual-stack host (430) detects a first multicast request from a source host (410) to a destination host (420) using a first protocol. The dual-stack host (430) initiates a timer. When the timer expires, the dual-stack host (430) sends a second multicast request message to the destination host (420) using each of the first and second protocols. The dual-stack host (430) monitors whether the destination host (420) responds using one or both of the first and second protocols and determines whether protocol translation is necessary to allow the source and destination hosts to communicate. If required, the dual-stack host (430) then invokes protocol translation to provide the source host (410) with a synthesized address for communicating with the destination host (420).
摘要翻译：使用第一和第二协议（450,460）在组播网络（470）上提供双栈主机（430）。双栈主机（430）使用第一协议检测来自源主机（410）到目的主机（420）的第一多播请求。双栈主机（430）启动定时器。当定时器到期时，双栈主机（430）使用第一和第二协议中的每一个向目的主机（420）发送第二组播请求消息。双堆栈主机（430）监视目的地主机（420）是否使用第一和第二协议中的一个或两个进行响应，并且确定协议转换是否需要允许源和目的主机进行通信。如果需要，双栈主机（430）然后调用协议转换以向源主机（410）提供用于与目的主机（420）进行通信的合成地址。

摘要： A method (500), a system and a gateway (400) for communicating between hosts in private networks having IPv4 address spaces are disclosed. One or more DNS query messages for resolving resource records are transmitted (502) from a first private network for a remote host in a second private network. One or more DNS replies comprising a private IPv4 address for the remote host are received (504). If the one or more DNS replies comprise a synthesized IPv6 address, the IPv6 address is extracted from the replies and a peer IPv4 address in the first network is allocated for the remote host (508). The IPv6 address comprises a global IPv6 prefix and the private IPv4 address for the remote host. The peer IPv4 address is associated with an extracted IPv6 address for the remote host. The remote host is addressed using the IPv6 address for transmission of IPv4 packets from the first network addressed using the peer IPv4 address (510). The system comprises an application-level gateway of a domain name system (DNS-ALG), a virtual table, and a translator. The gateway comprises the foregoing system and a domain name system (DNS) server.
摘要翻译：公开了一种用于在具有IPv4地址空间的私有网络中的主机之间通信的方法（500），系统和网关（400）。用于解决资源记录的一个或多个DNS查询消息从用于第二专用网络中的远程主机的第一专用网络发送（502）。接收包括远程主机的专用IPv4地址的一个或多个DNS应答（504）。如果一个或多个DNS应答包括合成的IPv6地址，则从应答中提取IPv6地址，并为远程主机分配第一网络中的对等IPv4地址（508）。 IPv6地址包括全局IPv6前缀和远程主机的私有IPv4地址。对等IPv4地址与提取的远程主机的IPv6地址相关联。使用IPv6地址对来自使用对等IPv4地址寻址的第一网络的IPv4分组进行远程主机寻址（510）。该系统包括域名系统（DNS-ALG）的应用级网关，虚拟表和转换器。网关包括上述系统和域名系统（DNS）服务器。
