Networking solutions provider D-Link broadened its selection of scalable switching solutions for small to medium-size businesses, including the DGS-6604 chassis-based switch and DGS-3620 and DGS-3120 xStack series switches. The switches offer 10-Gigabit Ethernet aggregation, and Power Over Ethernet support, as well as IPv6 support including IPv6 Tunnel, ICMPv6, IPv6 Neighbor Discovery, DHCPv6, RIPng and OSPFv3.
The DGS-6604 is based on based on a high-speed switch fabric with capacity of up to 576G bps and system performance of up to 428M bps, and features bottleneck-free distributed packet switching/routing and intelligent line cards with on-board Level 2 (L2)/Level 3 (L3)/Level 4 (L4) switching controllers, up to four redundant load-sharing power modules, hot swappable line cards, a replaceable fan module, 802.1D/w/s spanning tree, 802.3ad link aggregation and virtual router redundancy protocol (VRRP) support.
It also features 802.1p priority queues/multilayer class of service (CoS), including flow-based bandwidth control and broadcast/multicast storm control to ensure priority to network services such as VOIP, video conferencing, IPTV, and IP surveillance and security features including L2/L3/L4 Multi-Layer Access Control List (ACL), external RADIUS authentication support and SSH support.
The DGS-3620 xStack series offers an alternative to the chassis form factor with switches that deliver Layer 3 features. Up to four dual-purpose uplink/stacking 10GE SFP+ ports allow creation of the appropriate networking architecture for a variety of core applications. The four 10GE ports can be aggregated to allow a maximum 40G-bps backbone bandwidth. In addition, the DGS-3620 series supports physical and virtual stacking with other D-Link switches, providing the simplicity of Single IP management. These switches also provide IPv6 support, QoS and Multi-Layer ACL filtering, packet routing and protocol filtering/inspection.
