DCME is recommended for 320 users within the application environment. DCME-320 integrates broadband router, firewall, switch, VPN, traffic management and control, network security, wireless controller and easy configuration. It is ideal for small and medium enterprises, schools, government, chain, medium-sized Internet cafes, operators and other complex network environment.
Main Features
  • Strong performance under advanced hardware architecture 

DCME-320 multi-core security gateway uses 64-bit multi-core processors, a dedicated ASIC high-speed switching engine making the entire hardware platform to run on a high-speed Ethernet architecture. This high-performance design makes the machine born with superior processing performance and provides a guarantee for depth detection data traffic shaping and stable operation of the security and defense, firewall / VPN, IPv6 and other rich upper layer software functionality.

  • Flexible interface types and functions

DCME-320 multi-core gateway provides a variety of interface types. The device contains eight Gigabit Ethernet ports + 2 Gigabit Combo interface and ports which have high voltage industrial grade security features to prevent static electricity, lightning damage to the equipment. The device supports Ethernet, FTTB optical fiber, ADSL, Cable. It supports load-balance, intelligent routing, link backup and other policies, covering most of the needs. DCME-320 also provides 2 USB2.0 interface for external storage expansion applications.

  • Accurate flow control and behavior management

DCME-320 provides accurate flow control policies based on applications, IP addresses, subscribers, protocols etc and set maximum, minimum, guaranteed bandwidth on uplink and downlink. Over 200 protocols can be identified via DCME-320 to set bandwidth guarantee, bandwidth control based on the specified protocol. With accurate NAT session limit, the threat of high session number caused via multi-process download-tools and virus attack.

  • Rich firewall functions

DCME-320 has powerful anti-attack capability.  With detailed statistics and accurate analysis on various packets such as ARP, IP, ICMP, TCP, UDP and other types of packets, attacks can be found and blocked including SYN Flood, DDoS, IP packet fragmentation attacks, IP address scanning attacks etc. And alarm information can be provided to make your network management more security.

Based on the advanced state detection technology, DCME-320 provides powerful anti-ARP ARP mechanisms including IP + MAC binding, ARP scanning technology, trusted ARP-learning, ARP-filtering. IP/MAC binding and anti anti-ARP mechanism between clients and devices can be done automatically.

  • Highly integrated access controller

DCME-320 security gateway can be used as access controller to set up wireless network with DCN AP devices. Based on smart management cluster technology, DCME-320 can monitor RF value in the location of each AP and adjust signal power and channel of each AP automatically according to user number or load balance policy. At same time, it can reduce interference of wireless signal to realize load balance and stability of the wireless network and provide perfect solution for middle/small wireless network and branches of large enterprise.

  • Efficient and friendly management and maintenance

DCME-320 security gateway adopts full graphic management Web page. Only three steps are needed to connect DCME-320 to the network with configuration wizard.

Various monitoring measures, including performance monitoring, failure alarming, virus/attack warning etc, and statistics and ranking information based on bandwidth and session are supported to the management and maintenance easily.

  • Green and efficient

DCME-320 security adopt next generation of hardware chipset. While ensuring powerful processing capability at the same time, low-power electrical components and fanless design make the devices power consumption less than 30watts.
