With the high-performance hardware platform, service providers can easily extend network topologies while enabling robust security, QoS and management functions to help customers fulfilling different needs and to support the IPv6 for trouble-free future network expansions. ■ IGMP Snooping v1, v2, v3; MVR ■ Multilayer-aware (L2/L3/L4) ACL for security protection ■ Wire speed ■ High redundancy and resilient architecture with RSTP and Port Trunking ■ “Front access” design; external alarm input/output block Benefits Advanced QoS for significant services Consistent service quality and reliable connecting ability in a converged network is the key for Carrier to connect and satisfy customers; therefore the ability to control traffic flow and set traffic policy becomes more critical than ever. The ZyXEL MES3500-24/MES3500-24F 24-port FE L2 Switch offers wire-speed flow control that classifies and prioritizes the incoming packets according to the predefine QoS policies that meet requirements of service providers. In terms of classification, the Differentiated Services Code Point (DSCP) field and the 802. 1p Class of Service (CoS) field are identified to assess the priority of incoming packets. Classification and 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 MES3500-24/MES3500-24F provides 8 priority queues per port for different types of traffics, allowing service providers to set policy-based rate limitations that take full advantage of constrained network resources and guarantee the best performance...
