Benefits:

Advanced QoS for significant services

Consistent service quality and reliable connecting ability in a converged network is the key for service providers to win customers and build loyalty; therefore the ability to control traffic flow and set traffic policy becomes more critical than ever. The MGS3520 Series 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 MGS3520 Series 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 and 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 MGS3520 Series offers a complete set of security features to protect user data while administrating the traffics. The intrusion lock function detects the “plugged” and “unplugged”status change of Ethernet cables, and the switch would deactivate a specific port automatically if needed, and the 802.1X authentication can secure the network from unauthorized users. Port security provides the ability to deny unauthorized users from accessing the network. Moreover, the 802.1X feature cooperating with RADIUS is useful to prevent unauthorized access based on username and password (or other credentials) and acts as powerful access control for converged networks with mixed wired and wireless access.

The MGS3520 Series provides a multilayer (L2/L3/L4) ACL suite of sophisticated policy-based control mechanisms that enables service providers to deploy easily based on actual network environment needs via a Web GUI or command line interface to prevent abnormal or illegal access. The policies can be defined to deny packets based on source and destination MAC addresses, IP addresses or TCP/UDP ports.
 

Resilient and redundant design

A quick recovery and round-the-clock network is vital for service providers to establish a robust network. The MGS3520 Series provides comprehensive features to make sure network is well operated. The IEEE 802.3ad Link Aggregation feature reduces network downtime by providing redundant paths and bandwidth aggregation to critical connections, while IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) allow immediate recovery from failed connections by sending packets via the backup link. Furthermore, since the MGS3520 Series supports backup power system, the power is supplied to the switch in case of an unexpected outage.
 

Agile traffic control for converged networking applications

Design for access layer converged data, video and voice applications, the Zyxel MGS3520 Series has a rich Layer 2 feature set that can shape the traffic for diverse VoIP, video conference, and IPTV deployment. Supporting L2 multicast and IGMP snooping, the MGS3520 Series can support large IPTV deployments, which using bandwidth efficiently by directing multicast traffic to the subscribers only. The Multicast VLAN Registration (MVR) function ensures better network security by allowing a single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. These advanced traffic control features of the MGS3520 Series provide hotels, businesses, and educational institutions greater agility and more effective traffic management for converged applications of today.
 

Future-Proof connectivity for evolving networks

The Zyxel MGS3520 Series helps business and organizations stay ahead and get ready for future IPv6 networks. It supports dual stack (IPv4 and IPv6) and IPv6 host that allows business and organizations to deploy the MGS3520 switch at the network edge today, and easily migrate to the next-generation Internet Protocol in the future. With support for IPv6 ACL packet filtering, the MGS3520 L2 Gigabit switch can create secured IPv6 networks that are protected from illegal IPv6 clients. The MGS3520 Series is designed with a comprehensive set of IPv6 management features that include ICMPv6, neighbor discovery and DHCPv6 relay, which facilitate the migration to next-generation networking applications without an extensive equipment upgrade.
 

Optimized design for Metropolitan Area Network (MAN)

The MGS3520 Series adopts the “front access” design for technicians to easily wire and maintain outdoor cabinets. The external alarm input/output block connects mechanical cabinet parts to the management network and offers better protection to the equipment.
 

Carrier switches supports Digital Diagnostics Monitoring Interface (DDMI) SFP

The enhanced digital interface allows real-time access to device operating parameters, and includes optional digital features such as soft control and monitoring of SFP I/O signals. In addition, it fully incorporates the functionality needed to implement digital alarms and warnings.

The digital diagnostic monitoring interface enables users to have the capability of performing component monitoring, fault isolation and failure prediction tasks on their transceiver-based applications.
