摘要： A distributed address database management technique involves maintaining an address database by each of a number of interconnected modules. Each module maintains a number of locally owned address entries and a number of remotely owned address entries in the address database. Each module monitors the status of its locally owned address entries, maintains the locally owned address entries based upon the status, and provides the status to the other interconnected modules. Each module maintains the remotely owned address entries based upon the status received from the other interconnected modules. When a module adds a locally owned address entry to its address database, the module notifies the other interconnected modules, which in turn add a corresponding remotely owned address entry to their respective address databases. When a module purges a locally owned address entry from its address database, the module notifies the other interconnected modules, which in turn purge the corresponding remotely owned address entries from their respective address databases. Each module may periodically send a keep-alive message including a list of active addresses to the other interconnected modules, which maintain a persistence timer for each of the remotely owned address entries and purge a particular remotely owned address entry if the corresponding persistence timer expires before receiving a keep-alive message identifying the remotely owned address entry as an active remotely owned address entry. Upon receiving a keep-alive message, a module adds a remotely owned address entry for a particular address to its address database if such a remotely owned address entry is not already maintained in the address database. A module purges all remotely owned address entries from its address database if the module is reconfigured to operate in a stand-alone mode. A module purges all remotely owned address entries associated with a particular interconnected module if that particular interconnected module is removed.

摘要： A technique for domain name resolution in a communication network having multiple overlapping address domains involves translating a destination host domain name into a destination host local address that is ambiguous within the communication network, and then translating the destination host local address into a unique destination host global address. A domain name system proxy uses a domain name system server in the destination address domain to translate the destination host domain name into the destination host local address, and uses a network address translator to translate the destination host local address into the destination host global address.
摘要翻译：在具有多个重叠地址域的通信网络中用于域名解析的技术涉及将目的主机域名转换为在通信网络内不明确的目的地主机本地地址，然后将目的地主机本地地址转换为唯一目的地主机全局地址。域名系统代理使用目的地址域中的域名系统服务器将目的主机域名转换为目标主机本地地址，并使用网络地址转换器将目的主机本地地址转换为目标主机全局地址。
