Typical Case -Rail Transit——Automatic Fare Collection (AFC)
MRD™子午线®—Rail Transit System Solution
MRD™子午线®—Rail Transit AFC Feature
1.Rail Transit (AFC) network equipment should be fanless, with high protection glass and reliability,and redundant power supply to ensure the normal operation of the ticketing business.
2.The redundant switching time of each access network should be less than 50ms.
3.Field access ring network adopts industrial switches with high MTBF and high LifeTime.
4.AFC system can access to transmission node network (SDH) through Aggregation node of each site.

High Protection Class Industrial Switch
1.Full Switching Function—support layer-3 function, Avoid the network storm effectively.
2.Multi Port Form—Reach the protection requirement in any port forms(M12/RJ45).
3.High Protection Level—Support the requirements of IP54/IP65/IP67
4.Multi Port Function—Support optic fiber interface and BYPASS function.
Next Generation Industrial redundant Network
1. IEC orgnazation has already issued IEC62439-3-5 and regulated High-availability Seamless Redundancy(HSR) in 2012.
2. HSR protocol is a public and standard redundant protocol.
3. HSR protocol is a double-emission and optional-receiving mechanism to realize zero-packet-loss, zero switching time high redundant industrial ring network.
4. HSR(IEC62439-3-5) protocol and PRP(IEC62439-3-4) protocol can be adopted at the same time, and can realize the switching of network A and network B in hardware layer.
PRP-Parallel Redundancy Protocol
DANP is the node supporting PRP protocol, and separately connect network A and Network B.
DANP have same IP and MAC address in Network A and Network B, and send the same packet to Network A and Network B at the same time.
HSR-High Reliability Seamless Redundant Backbone Network
HSR+PRP Single IP 0ms Redundant Network
HSR 0ms Redundant Network
