摘要： A first network device includes: a forwarding controller configured to forward received data; and a fault detector configured to detect occurrence of a failure in a remote second relay node. The forwarding controller includes: a forwarding unit configured to forward the received data; and a modifier configured to modify the received data for detection of the occurrence of a failure in the second relay node. The modifier includes (i) a flag option marker configured to attach a flag to data; (ii) a sequence adding unit configured to add a protocol specific number to a sequence number; and (iii) a sequence subtracting unit configured to subtract the protocol specific number from an acknowledgement number. The fault detector detects the occurrence of a failure in the remote second relay node, based on at least one of the flag and the acknowledgement number.

摘要： In a multicast delivery system, A delivery server enciphers delivery data by using a current use cipher key to generate enciphered data and transmits a multicast packet containing the enciphered data and a current use key identifier indicative of a pair of the current use cipher key and a current use decipher key as current use keys. A key management server holds as a current use key data, a set of the current use decipher key and the current use key identifier, and transmits a set of the current use decipher key and the current use key identifier as a current use decipherment key data in response to a current use key data request.
摘要翻译：在组播传递系统中，传送服务器通过使用当前使用的密码密钥来产生传送数据，以生成加密数据，并发送包含加密数据的多播分组和表示一对当前使用密码密钥的当前使用密钥标识符，当前使用解密密钥为当前使用密钥。密钥管理服务器保存当前使用密钥数据，当前使用解密密钥和当前使用密钥标识符的集合，并将当前使用解密密钥和当前使用密钥标识符的集合作为当前使用解密密钥数据响应当前使用的密钥数据请求。
