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 ZyXEL MES-3528 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 MES-3528 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 ZyXEL MES-3528 offers a complete set of security features to protect user
data while administrating the traffics. 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 MES-3528 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
Resilient and redundant design
A quick recovery and round-the-clock network is vital for service providers to establish a robust network. The MES-3528 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.
Digital Diagnostics Monitoring Interface (DDMI) SFP support
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.
