3. Unified Services Router Introduction 1. This feature is NOT supported in DSR-250N and 500N DSR-250N/500N/1000N: Another Momentum for Router Market Hybrid VPN demand is stronger than ever, its annual revenue would be even. DSR-250N, DSR-500N and DSR-1000N are targeting at advanced router market which could fit customers into both IPv4 and IPv6 environments and high performance and provide comprehensive VPN functions, including: PPTP/L2TP/IPSec/SSL VPN. Furthermore DSR-500N and DSR-1000N deliver professional routing features, such like: OSPF and RIP; equip with dual WAN interfaces, and achieve route failover and load balancing. In the cost sensitive SMB segment, D-Link adopts cutting-edge and cost-effective hardware platform and delivers almighty 802.11 a 1 / b / g / n (ratified version) WiFi support. DSR-250N provides 8 LAN gigabit ports, DSR-500N and DSR-1000N include 2* Gigabit WAN ports, and 4* Gigabit switch ports for LAN network. For wireless part, both DSR-250N and DSR-500N supports 2.4Ghz single band IEEE 802.11b/g/n ratified version with 2x2(DSR-250N) and 2x3(DSR-500N) MIMO technology. DSR-1000N supports 2.4/5Ghz configurable dual band, IEEE 802.11a/b/g/n ratified version with 2x3 MIMO technology.

4. Market Trend Analysis Hybrid VPN demand is stronger than ever, its annual revenue would be even greater than double within 4 years! With technology evolution, such as: VPN and IPv6; and technology convergence, including: WiFi, Security, and triple-play etc., brings traditional router into another level: “Services Router” SMB is our major battle filed, however for USD$150 ~ USD$500 price band, D-Link does NOT have any corresponding product, and NETGEAR and Linksys dominate this segment and sell thousands units/month.
