27. 7750/7500 compete policy Much IPv6 and MPLS features can block 7700/7500 Distribution IPv6 and MPLS structure will help customer protect investment Attention service card in the project and we can introduce FW or VPN device to customers and split service function from the project Cost effective for each GE or 10GE ports Much slots number give customer much more extend ability The vertical slot design help cooling system work well and give much lower running temperature for product For the 3com 7700, the performance are same. And if h3c S7500 with Salience III plus engine, the performance higher than the DCRS7608 but we can provide cost effective GE and 10GE port to customers. 3com sales discount only 60% off in generally and only big project can upto 70% or more (the dead line discount is 76%), but we have most flexible price policy to against them.

32. DES-7200 compete policy The DES-7200 has more features such as IPFIX,NAT and POE. DCRS-7608 has much more IPv6 features than DES-7200 and support distribution IPv4/IPv6/MPLS forwarding DES-7200 price just little higher than DCN product but more famous in customer DES-7200-24G2XGE decrease total price with high port density delivery. We need split 10G and GE in different line cards then extend price space. We should make bundle price for 7608 with 2XFP12GX12GT or 2XFP8GX16GB to compete with Dlink. Because our chassis price higher than DES-7200 after discount, we must configuration much line card to give customer more profit or chassis can decrease price list.
