protocols to join and function together as a larger and more robust compound network topology. O-Chain providing

ease-of-use while maximizing fault-recovery swiftness, flexibility, compatibility, and cost-effectiveness in one set of

network redundancy topology.



MRP : Media Redundancy Protocol (MRP) is a data network protocol standardized by the IEC 62439-2. It allows

rings of Ethernet switches to overcome any single failure with recovery time much faster than achievable with

Spanning Tree Protocol.



IP-based Bandwidth Management : The switch provide advanced IP-based bandwidth management which can limit

the maximum bandwidth for each IP device. User can configure IP camera and NVR with more bandwidth and limit

other device bandwidth.



Application-Based QoS : The switch also support application-based QoS. Application-based QoS can set highest

priority for data stream according to TCP/UDP port number.



Device Binding Function : ORing special Device Binding function can only permit allowed IP address with MAC address

to access the network. Hacker cannot access the IP surveillance network without permission. It can avoid hacker

from stealing video privacy data and attacking IP camera, NVR and controllers.



Advanced DOS/DDOS Auto Prevention : The switch also provided advanced DOS/DDOS auto prevention. If there

is any IP flow become big in short time, the switch will lock the source IP address for certain time to prevent the

attack. It’s hardware based prevention so it can prevent DOS/DDOS attack immediately and completely.



Modbus TCP : This is a Modbus variant used for communications over TCP/IP networks.



IEEE 802.3az Energy-Efficient Ethernet : This is a set of enhancements to the twisted-pair and

backplane Ethernet family of networking standards that will allow for less power consumption during periods of low

data activity. The intention was to reduce power consumption by 50% or more.
