1) ARP/Heartbeat prob ing
ARP/心跳报文断线检测
2) heartbeat detection
心跳检测
1.
The technology of heartbeat detection is introduced to enhance the reliability of remote control.
通过引入数据覆写技术设计了数据销毁系统,使用心跳检测技术解决了远程控制的可靠性。
2.
In theory, disaster tolerance technology includes heartbeat detection technology and many other technical means, such as two module backup, computer cluster, storage area network, etc.
从范畴上讲,容灾技术包括心跳检测技术在内的许多技术手段,如双机热备份,计算机集群,存储区域网络等。
3.
A new scheme is proposed,it uses only two PC Server without Disc Array,through database synchronization,intelligent database access layer and heartbeat detection,when one PC Server failed it will automatically switch to another one seamlessly.
针对这一问题,提出一个方案,仅使用两台普通PC Server,没有高性能的磁盘阵列,每台服务器都充分应用,通过数据库同步,智能数据库访问层,心跳检测,当其中一台服务器出现异常时,能够自动无缝地切换到另一台服务器。
4) packet check
报文检测
1.
Consisting of key exchange protocol and packet check protocol,it implements dual authentication between hosts,and guarantees the authenticity and integrity of packets in transmission.
该机制由密钥协商和报文检测协议组成,实现通信双方的双向身份验证,保证传输过程中报文的真实性和完整性。
2.
Consisting of key exchange protocol and packet check protocol,the mechanism provides control to the behavior of hosts and packet transmission inside the network,which is suitable for mini-scale networks such as LANs and can solve security problems inside the network such as spoofing,modifying and so on.
文章提出了一种基于主机的网络层访问控制机制,它由密钥协商协议和报文检测协议组成,对主机的网络行为和报文传递提供安全控制,适合在局域网等小范围网络实施,能够解决网络内部的假冒、篡改等安全问题。
