High-level IPTV Application with MVR (Multicast VLAN Registration)
Solution
High-level IPTV application is designed for using wide-scale deployment of
multicast traffic across a service provider network.It’s important to reduce the
redundant bandwidth of IPTV stream in the higher bandwidth required network.
MVR allows a subscriber on a port to subscribe and unsubscribe to a multicast
stream on the network-wide multicast VLAN. It enables the single multicast VLAN
to be shared in the network while subscribers remain in separate VLANs. MVR
provides the ability to continuously send multicast streams in the multicast VLAN,
but to isolate the streams from the subscriber VLANs for bandwidth and security
reasons.
Intelligent SFP Diagnosis Mechanism
The GS-5220-46S2C4X supports SFP-DDM (Digital Diagnostic Monitor) function
that greatly helps network administrator to easily monitor real-time parameters
of the SFP, such as optical output power, optical input power, temperature, laser
bias current, and transceiver supply voltage.
IPv6 / IPv4 Dual Stack
Supporting both IPv6 and IPv4 protocols, the GS-5220-46S2C4X helps the data
center/service provider to experience the IPv6 era with the lowest investment as
its network facilities need not to be replaced or overhauled if the IPv6 FTTx edge
network is set up.
