7.8 IGMP Snooping
The OLT can passively snoop on IGMP Query, Report and Leave (IGMP version 2) packets
transferred between IP multicast routers/switches and IP multicast hosts to learn IP multicast
group membership information. It checks IGMP packets passing through it, picks out the
group registration information, and configures multicasting accordingly. IGMP snooping
allows the OLT to learn multicast groups without you having to manually configure them.
The OLT forwards multicast traffic destined for multicast groups (that it has learned from
IGMP snooping or that you have manually configured) to ports that are members of that
group. The OLT discards multicast traffic destined for multicast groups that it does not know.
IGMP snooping generates no additional network traffic, allowing you to significantly reduce
multicast traffic passing through your OLT.
7.9 DBA (Dynamic Bandwidth Allocation)
When network congestion occurs, dynamic bandwidth allocation allows the OLT to quickly
re-assign unused bandwidth based on traffic requirements. Bandwidth re-assignment can be
for an ONU or for the priority-level queues. In addition to reassigning bandwidth on the go,
DBA helps to ensure quality of service on the network.
By default, the OLT uses the Plato DBA algorithm that allows you to fully utilize bandwidth in
your network environment. With Plato DBA algorithm, the OLT assigns bandwidth based on
link priority and delay tolerance. In addition, the OLT guarantees a minimum upstream
bandwidth and provides the best-effort maximum upstream bandwidth.
