Abstract

DC60 (03/04/41) This invention describes a technique for determining the network model in which each node of the network may send a cell requesting network pattern information, each of which accepts a cell. Requests for information on the network model are compared. This cell and the cell that holds data in the table. Look inside to determine. The switch receives the cell that Is it the same, come first and then through a shorter path? If this cell has been accepted first Then through a shorter path This cell will be discarded, if not, this will give the table a modern look, the cells that are not abandoned will be re-exported on all output ports except the output port corresponding to this input port on which the cell can. Been accepted, this switch is also suitable The same applies to cells that request network information form by sending. Response cell The network model returns to the node where the request for network-style information was initiated in such a way that every switch in the network can determine the network model of the entire network. For determining the network model of the network Which each node of the network may transmit Network model information request cell Each switch which The cells that request information are accepted, the network format will be compared. This cell and the cell that holds data in a table, look inside to determine the switch, get the same cells first, then pass. A shorter route? If this cell has been first admitted through a shorter path This cell will be discarded, if not, it will give the open table a modern look. Cells that have not been abandoned will It has been re-exported on all output ports except the output port implied to this input port, on which the cell has been imported. This switch also corresponds to the request cell. Networked information by sending a networked response cell The network returns to the node where the request for information forms the network. Get started Like this Every switch in the network can determine the image. Network model of the whole network

1. The methodology for determining the network layout of a network consists of the steps of (a) the first node sending a group of data to the number of output ports. One or more ports (b) the second node, at least one node accepts the packets as As mentioned on the input port (c), the second node compares that group of data. With tables that store data in memory in the aforementioned second nodes and later Will set a variable indicating that Has the group been previously received? (D) depending on the conditions in step (c) if the tag group:
