D-LINK DGS-1100-10/ME Managed L2 Metro Ethernet Switch

D-Link’s DGS-1100-10/ME Managed L2 Metro Ethernet Switch is a managed Gigabit Ethernet switch with eight 10/100/1000Base-T ports and two combo ports. It is designed to be used as a high-end residential switch or access layer switch in a Metro Ethernet. Targeted at IPTV applications, it provides complete multicast functions in a reliable hardware design. The Ethernet port can sustain 6 kV voltage surges so the device can be protected from being damaged by events such as lightning striking outdoor wires. The combo uplink port design makes it suitable for both ETTH or FTTB/FTTH application.

Multicast Capability
With the growing demands of IPTV usage, the DGS-1100-10/ME is ideal as it provides a variety of functions to enhance transmission quality and management efficiency, such as IGMP Snooping, Limited IP Multicast, ISM VLAN, and MLD Snooping for an IPv6 environment. In Limited IP Multicast, users can set Multicast Address profiles and associate them to a port or multiple ports, allowing the switch to permit or deny join requests sent by subscribers. The ability to set a profile eases the management effort required to add or delete subscribers from a channel package. ISM VLAN (IGMP Snooping Multicast VLAN) needs configuration on both the access switch and the uplink aggregation L3 switch, and the duplicated stream can be eliminated in the uplink when users in different VLANs are watching the same channel. While migrating to IPv6, MLD Snooping takes over and ensures that multicast quality stays high in the future when IPv6 becomes widely used.
