** Telco-class Layer 2 Gigabit Ethernet Switch for Fiber Backbone Applications** ** Meeting industry standards** The Metro Ethernet Forum (MEF) is a global industry alliance comprised of more than 175 active members representing Carrier Ethernet industry groups. The forum develops technical specifications & implementation agreements to promote interoperability & deployment of Carrier Ethernet services worldwide. The Zy XEL MGS-3712F is aligned with carrier-class standards for Ethernet Private Line (EPL), Ethernet Virtual Private Line (EVPL) & Ethernet LAN (E-LAN) of Metro Ethernet Forum (MEF), & the Series has been certified as MEF-9 & MEF-14 compliant. ** Advanced Qo S for significant services** Consistent service quality & reliable connecting ability in a converged network is the key for service providers to win customers & build loyalty; therefore the ability to control traffic flow & set traffic policy becomes more critical than ever. The MGS-3712F offers wire-speed flow control that classifies & prioritizes the incoming packets according to the predefine Qo S policies that meet requirements of service providers. In terms of classification, the Differentiated Services Code Point (DSCP) field & the 802.1p class of service (Co S) field are identified to assess the priority of incoming packets. Classification & reclassification can be based on criteria as specific as rules based on IP, MAC addresses, VLAN ID or TCP/UDP port number. For bandwidth management, the MGS-3712F provides 8 priority queues per port for different types of traffics, allowing service providers to set rule-based rate limitations that take full advantage of constrained network resources & guarantee the best performance. ** Enhanced security for protection among customers** Avoiding subscribers affecting each other on a shared network or shared device is a major concern for service providers. The MGS-3712F offers a complete set of security features to protect us
