摘要： There are provided a system and a method of determining a physical connectivity of a new node connected to a dynamic communication network comprising a plurality of connecting nodes each comprising a plurality of ports. The method comprises: (a) responsive to automatically discovering a new node connected to the dynamic communication network, obtaining address data characterizing a network address of said discovered new node; (b) querying all known connecting nodes and generating a port dataset representing all ports thereof which have registered address data characterizing the network address of said discovered new node; (c) defining, by analyzing the generated port dataset, a port and respective connecting node which said discovered new node is directly connected to.

摘要： Method and system for restricting a first node in a broadcast domain of an IP (Internet Protocol) network from communicating with one or more other nodes. Each of the first node and the one or more other nodes has a respective translation table that maps an IP address to a respective physical address of all nodes with which the first node and the one or more other nodes have communicated. Embodiments of the invention describe obtaining communicated data including address resolution messages and accessing an address resolution table representative of address resolution activity in the network. Responsive to the communicated data indicating that the first node is communicating with other nodes, restricting the first node from communicating by generating and conveying a restricting address resolution message using information stored in the address resolution table, the restricting address resolution message including a substitute physical address.

摘要： The present invention provides a method and an apparatus for determining topology of a dynamic network in respect of which there is maintained network data containing (a) node data representing a set of nodes, (b) address data representing a respective MAC (Media Access Control) address of each node, and (c) connectivity data representing a respective connectivity of each node. The dynamic network is cyclically monitored so as to determine during each cycle new nodes that have been connected to the dynamic network since a previous cycle and vanished nodes that have been disconnected from the dynamic network since the previous cycle. The respective connectivity of each new node is determined by identifying a port in a switch to which the respective new node is connected. The network data is augmented so as to include node data representative of the new nodes, and the respective address data and connectivity data of each new node, while node data representative of each vanished node is removed from the network data, as well the respective address data and connectivity data thereof. At the end of each cycle the respective connectivity data of all nodes in the set are indicative of the respective network topology.
摘要翻译：本发明提供一种用于确定动态网络拓扑的方法和装置，其中维护网络数据，其中包含（a）表示一组节点的节点数据，（b）表示相应MAC的地址数据（媒体访问控制）地址，以及（c）表示每个节点的相应连接性的连通性数据。循环监视动态网络，以便在每个周期期间确定自上一个循环以来已连接到动态网络的新节点以及自上一个周期以来与动态网络断开连接的已消失的节点。通过识别相应新节点连接到的交换机中的端口来确定每个新节点的相应连接性。增加网络数据以包括表示新节点的节点数据，以及每个新节点的相应地址数据和连接性数据，而代表每个消失的节点的节点数据从网络数据中移除，以及相应的地址数据和连接数据。在每个周期结束时，集合中所有节点的相应连接数据表示相应的网络拓扑。
