In a converged network, consistent service quality and reliable connecting ability are crucial for carriers to connect and please consumers; as a result, the ability to control traffic flow and create traffic policy is more important than ever. The Zyxel MES3500 series provides wire-speed flow control by classifying and prioritizing incoming packets based on predefined QoS criteria that fulfill service provider requirements. In terms of classification, the 802.1p Class of Service (CoS) field and the Differentiated Services Code Point (DSCP) field are used to determine the priority of incoming packets. Classification and reclassification can be based on a variety of parameters, including IP, MAC, VLAN, and TCP/UDP port numbers. The MES3500 series includes 8 priority queues per port for different categories of traffic for bandwidth control, allowing service providers to define policy-based rate limits that take full advantage of constrained network resources and ensure the greatest performance. Service providers are concerned about subscribers interfering with each other on a shared network or device. The Zyxel MES3500 series includes a comprehensive set of security capabilities for safeguarding user data while managing traffic. The ability to prevent unauthorized users from accessing the network is provided by port security. Furthermore, the 802.1X functionality, which works in conjunction with RADIUS, is excellent for preventing unwanted access based on login and password (or other credentials) and serves as a robust access control for converged networks with mixed wired and wireless access. The MES3500 series offers a multilayer (L2/L3/L4) ACL suite of complex policy-based control mechanisms that service providers can readily configure based on their specific network environment demands via a Web GUI or command-line interface to prevent aberrant or unauthorized access. Packets can be denied depending on source and destination MAC addresses, IP addresses, or TCP/UDP ports, according to the regulations. Service providers must have a fast recovery time and a network that is available 24 hours a day, seven days a week in order to build a reliable network. The MES3500 series offers a wide range of capabilities to ensure that the network runs smoothly. IEEE 802.3ad Link Aggregation reduces network downtime by providing redundant paths and bandwidth aggregation to critical connections, whereas IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) allow for immediate recovery from failed connections by sending packets over the backup link. The expanded digital interface provides real-time access to device operating parameters, as well as optional digital functionality like soft control and signal monitoring for SFP I/O signals. Furthermore, the MES3500 series includes all of the necessary characteristics to integrate digital alarms and warnings from fault isolation and failure prediction jobs, as well as component monitoring. The MES3500 series’ digital diagnostic monitoring interface allows customers to quickly discover packet loss from transceivers.
