What is the promiscuous regime?
The promiscuous mode is a network card configuration that transmits all packets to the network adapter control and protocol. Many cable and wireless network adapters and their drivers are supported. Promiscity mode is used by network analyzers, protocol analyzers and sniffing packets to allow network traffic control. Some network bridges are also used to pass operation from one side of the bridge to the other. In its normal operation mode, it only processes Unicast and broadcast packages. Packet Unicast is one that is focused specifically on this network card. In contrast, the transmitting packet is intended to receive all the devices connected to the network. Both types of packets are usually accepted by a card, processed by its controller and handed over to the network protocol tank. For the use of this mode, one or more addresses for multi -way broadcasting are programmed via its controller. When multi -mounted mode is allowedThe card also receives and processes all packets of multi -way broadcasting to the group. For comparison, promiscuous mode allows you to receive and process all packets, regardless of the type or directory.
network adapters that do not include hardware support, support multi -way broadcast support, significantly burden their drivers and the protocol tank. If multi -way broadcast mode is allowed on such a card, the hardware is usually placed in promiscuous mode. The software must then filter out each packet that is not focused on one of the required addresses of the multi -way broadcasting group. This will place a very significant load on the central processor and on the axis core. Generally, it also increases network response time.
SNIFFING PACKAGE is a frequently headed use for promiscuous regime, also known as the Promisc regime. Network analyzers and Sniffer Packet software in this mode can captureAll network traffic that can "hear". Upon adoption, packets can be stored for later analysis and decoding with the same or more complicated software. Operation accepted in this mode in the cable network is usually limited to machines connected to a network switch or hub. Wireless operation is usually limited to a specific service set or channel if the radio frequency monitor mode is not used.
