In Snooping mode,
management on status of multicast member. It just implements
IGMP message snooping and forwarding passively. It has a little
influence on the system load. However, it greatly increases
protocol processing load of the uplink equipment.
In Proxy mode, the system manages status of multicast member
actively, efficiently reducing the protocol load of the uplink
device.
Router mode is a simplified proxy mode. In case that multicast
service is directly sent to the uplink port, the system does not
require uplink port for multicast service dynamically.

EPON Service

EPON (Ethernet Passive Optical Network) is combination of some
optimal technologies and network architectures. Video on
demand and other 'triple-play' services of video, voice and data
require the provision of high bandwidth residential services
directly to consumers. Passive Optical Networks are the next
step beyond DSL and cable modems, delivering very high-speed
services to consumers over an all-optical access network.
EPON provides following functions:
EPON function card provides fiber access based on EPON
technology.
Single PON port supports 32 branches (20 KM) and 64
branches (<5 KM).
Downlink wavelength is 1490 nm, uplink wavelength is 1310
nm and CATV wavelength is 1550 nm.
VoIP services, CATV services, IPTV multicast services, high
quality broadband, and multi-service access for residential
subscribers.
It also meets fiber-to-the-home (FTTH) broadband service
requirements to accomplish the 'three-in-one' target. FTTH
greatly promotes development of the 'digital home' industry.
