Youken fiber optic switch is a two- and four-layer Gigabit managed switch, providing R electrical ports and independent ports . The hardware supports layer 2 full line-speed switching. Users can set various functions of the switch in B form through the Ethernet port. The built-in R and defense system can effectively defend against R, and various variant virus attacks. It is also equipped with many very powerful functions: comprehensive, r, various storm suppression, B r, , access control, etc. It is very suitable for small and medium-sized enterprises. Tandem applications for enterprises, campus networks and metropolitan area networks.

R defense: The address and port binding function and address security filtering function can effectively defend against R attacks and provide R protection for users who dynamically obtain addresses.

:Supports multiple strategies, based on priority settings. Each port provides a priority queue that can divide service levels according to different headers to achieve comprehensive functions. The port can be set to the highest priority for voice signals, greatly improving the voice quality of Internet calls. quality.

. .>: The following seven different attacks can be defended:
. .> () Attack: The attacker sends a flow of forged data packets with the same source address and destination address. The victim system attempts to send response information to itself. As a result, the system is interfered with and will be paralyzed or restarted.
. .>() B attack: The attacker sends forged data packets with the same source port number and destination port number, and the victim system tries to send response information to itself. The result is that the system is paralyzed or Restart.
. .>()r attack: The attacker uses the spoofed source address of the attack target to perform an operation to a broadcast address, and then all active hosts will reply to the target, causing network congestion or even Interrupt.
. .> () Flooding: Use broadcast storms to flood the entire target system so that the system cannot respond to legitimate communications.
. .> () Flood: Use or message to flood the entire target system.
. .> () Attack: Send a very large request packet (once), with the intention of causing the target computer's input buffer to overflow and paralyze it.
