 توضیحات

2Gbps Duplex Backplane for High-Bandwidth Transmissions

VES-1624FT-55A provides up to two Gigabit Combo. ports to upper layer network. Since VDSL2 ports support only 100Mbps in a very short distance, VES-1624FT-55A can provide virtually non-blocking interconnections from the subscriber ports to the network interface ports in most environments and application scenarios.

Complete Ethernet VLAN and multicast functions

The VES-1624FT-55A provides Ethernet VLAN features for both security and performance purposes. A VLAN is used to isolate traffics between different users/applications in order to provide better security and performance. By limiting broadcast traffics within the VLAN broadcasting domain, the performance can be enhanced. The IGMP snooping function is provided in VES-1624FT-55A to prevent unnecessary multicast traffic forwarding to all subscribers, thus optimizing bandwidth utilization for multicast applications such as broadcast video.

MVLAN consolidates same video stream requested by different VLANs

The multicast VLAN feature checks all VLANs to see if some have requested the same video stream. If they have, only one request instead of many will be issued and the stream is distributed to all requesting VLANs. The total amount of the video streams can be reduced significantly as a result.

Service Differentiation from Rate Limiting

In order to fulfill different customer needs, service providers need a network infrastructure that combines guaranteed performance and flexibility in service provisioning. Rate limiting on subscriber ports allows services to step up with 64Kbps increments for service providers to offer tiered services.

Upstream Access Control Mechanism

VES-1624FT-55A supports not only 802.1x port-based access control for subscriber authentication, but also defines a limited number of MAC addresses that can access the network from a particular port. This feature denies unauthorized access to the DSCAM to significantly enhance network security. Another access control feature is the capability to limit the number of users (MAC addresses) that can access the network simultaneously on a per-port basis, allowing the service provider to offer flexible billing plans. Besides that, VES-1624FT-55A provides per-port packet classification rules based on the header information of up to layer 4 and the corresponding action rules to manipulate the matched packets as needed.
