- ISM VLAN
ISPs will isolate the streams for different subscribers by VLANs for
security reasons.
Applications requires continuously multicast stream will cause
heavy traffic on the uplink ports of L2 access switch.
ISM VLAN register the multicast stream for subscriber VLANs saves
lot of bandwidth for uplink.

the telecom network.
Users’ LAN will connect to ISP network directly without any
protection.
LBD protects the ISP networks from the loop connection in those

Solutions for Reliability
- DHCP server Screening
For ISPs who did not provide CPE, users may buy home routers to
share a single ISP IP for their PCs or laptops.
If there is any misconnections on WAN/LAN ports, home gateways
will reassign the IP for ISP switch or other users if they renew IP
address.
DHCP Server Screen can discard the illegal DHCP offer to guarantee
the reliability of network.
