NVRAM is used to store parameter information in the system.2.3.2DPRAM (Dual-port RAM)The DPRAM is characterized by simultaneous access via two ports, with two fully independent data buses, address buses, and read and write control lines, typically used for data interactions between two processors. When one end is written to the data, the other end can be learned by polling or interrupting and reading the data it writes. Since the

Lspci detailed analysis using, PCI device tree

concept of the domain, each PCI domain can have up to 256 bus, each bus can support 32 devices, so the device number is 5 bits, and each device can have up to 8 functions, so the function number is 3 bits. Thus, we can conclude that the address of the above PCI device is the number 1th function on the No. 31st device on the No. No. 0 field No. 0 bus.What exactly is this PCI device above? Here is the output of the LSPCI command on my computer:00:00.0 host Bridge:intel Corporation 82845 845 (Broo

Troubleshooting of DDoS attacks on hosts at the source of LAN Paralysis

through the firewall restrictions. In the past, this host was lucky enough to become a zombie of Distributed Denial of Service (DDoS) attacks. Each time an EIP is connected, A ddos.txt file is automatically downloaded to an ftpserver. If the file is empty, the file is downloaded at a certain interval until the obtained file contains the IP address and port of the target host, and DoS attacks are initiated to the target host. This is the reason why network faults occur irregularly and irregularl

Switch Security (2)-MAC address flooding

Mac layer Attack rumor address floodA common two-layer attack or switch attack is a Mac flood, with an intruder using a large number of invalid source MAC addresses, which can cause the switch's cam table to overflow, because the switch cannot find the port corresponding to the destination MAC address in the MAC address table, causing the switch to periodically flood the data frames to all other ports, The switch will no longer receive new legitimate

The artificial neural network was cleverly built, using a hive automaton structure designed to tailor a machine called cam brainmachine ("Cam brain Machine") to a client (CAM is the abbreviation for cellular automata machine). The man boasted that the artificial network machine would have the intelligence of a cat. Many neural network researchers think

Working principles and differences between bridges and Switches Based on Network

you will ask now, why do we need two tables? Can't we have one ?? Hmm ~ The table was split into two for ease of understanding. In fact, the real net bridge should store a table (of course, it may be for speed-up or other reasons, it may also store the information in multiple tables. It depends on how it is implemented ~), For a table, the table records MAC-PortNum. 4. The vswitch is somewhat different, The vswitch also has a MAC-PORT table (the name of this table is
