8. Lantech Pioneering Industrial and IP Networks TM Dynamic ring coupling for train carriage exchange without reconfiguration –Train coupling topology is common in multi-unit trains for efficient operation, however, this would require auto configuration for railway operator. So a traditional coupling topology need to be tuned to fit with 2, 3 or even 4 cars exchanges. –In consideration of each car network has the same setting but with different IP as well as to limit multicast flows to certain ports –Each car has the DHCP server for port based DHCP network for easy maintenance Software Advantage & Comparison

9. Lantech Pioneering Industrial and IP Networks TM QoS base by VLAN (Advanced QoS) Most switches are able to adapt QoS function but the device must be able to acknoledge QoS packet or by port based QoS. However, through VLAN, the QoS setting can be simple. The “Advanced QoS” is the best and most convenience solution for traffic-management no matter the devices supporting QoS or not. Users can do planning at application level and make network performance more predictable and bandwidth utilization more effective. For example, IP cam and VOIP phone are in the same network but need to prioritize VOIP packet in VLAN1, with Advanced QoS, the VOIP packet will be sent in prior to video multicast packet where user don’t need to worry whether VOIP device is able to read QoS packet. Software Advantage & Comparison Video package VoIP package

10. Lantech Pioneering Industrial and IP Networks TM Mac based DHCP Server –The MAC-based DHCP simply assigns an IP address to a client according to its MAC address pre-setting inside the switch. In the switch configuration, users just only enable DHCP server and set one desired IP address to MAC address. This feature fits for one level network structure. Software Advantage & Comparison

11. Lantech Pioneering Industrial and IP Networks TM Hybrid DHCP Port & VLAN based distribution Software Advantage & Comparison By supporting DHCP option 82 and Port-based DHCP server simultaneously, not only the clients can get the fixed IP address assigned by the port number or VLAN ID where the device is connected, but the relay agents get the fixed IP address according to the port number it attached Most of switch products are not built in DHCP Option 82 server but relay agent function where network need another DHCP Option 82 server which might be a difficulty in harsh network like vehicle, train or track side

12. Lantech Pioneering Industrial and IP Networks TM Channel bonding for redundancy and bandwidth increment –Channel bonding is to build redundancy and load balance with the PC where support dual Ethernet interfaces. Software Advantage & Comparison
