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.

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.
