Salami Slicing

An embezzling method that involves removing extremely small increments of money from financial accounts on a system. This is usually done by rounding down decimal places and shuttling the tiny remainder to a ghost account. Done on a frequent enough timetable, large amounts of money can be amassed quickly. This type of fraud is difficult to detect.

Mesh Network

The term mesh network refers to a network topology in which devices are connected with many redundant interconnections between network nodes. In a true mesh network——wired or wireless ——every node has a connection to every other node in the network, whether directly or via hopping though intermediate nodes.

Looking specifically at wireless mesh networks, they are actually more truly switched wireless networks than those that use so-called wireless LAN switches. In a mesh network, packets are forwarded wirelessly from node to node. Products called WLAN switches, on the other hand, don't actually supportany wireless interfaces. Note, though, that mesh architectures don't preclude the use of a WLAN switch or other centralized management architecture on the wired side of the network.

切香肠法

一种挪用资金的方法，每次从系统的财务账号上移走数量极小的资金。通常是舍去小数点后面的数取整数而实现的，把舍下的小数放入一个幽灵账号。只要次数足够多，就能很快聚敛大量的资金。这类诈骗很难侦破。

网状网络

网状网络是指这样一种网络拓扑结构: 网络中的设备是通过网络节点之间的众多冗余互连连接起来的。在真正的网状网络(有线或无线)当中，每个节点与网络中的另一个节点相连，包括直接连接和通过中间节点跳接。

对于无线网状网络而言，这些网络实际上是真正的交换式无线网络，而不是那种使用所谓的无线LAN交换机的网络。在网状网络当中，一方面，信息包在节点之间以无线的方式传送。另一方面，被称做WLAN交换机的产品实际上并不支持任何无线接口。然而，请注意，网状体系结构并不排除使用WLAN交换机或网络的有线方面的其他集中式管理体系结构。
