Point-to-point and
Point-to-multipoint
Support
Point-to-point (coax)
Point-to-multipoint operation (coax) for up to 16 Subscriber CPEs per G.hn port
Ease of Operation
Supports firmware and configuration management of G.hn end-point devices
Encryption
AES-128 encryption with individual keys for each End Point. The Positron GAM Domain
Master is also acting as the G.hn Security Controller
Modulation and
Frequency Band
Supports OFDM 200 MHz.
Radio Band Notching function allows cohabitation with legacy analog cable TV channels
on coax cabling
Bandwidth
Management
Up to 1.7 Gbps with Dynamic Bandwidth Allocation to optimize throughput based on
nature of traffic flows with TDD Multiplexing for programmable upstream / downstream
ratio
Reliability and
Resiliency
State of the art LDPC Forward Error Correction (FEC)
Layer 2 Switching
Spanning Tree Protocol
(STP)
Standard Spanning Tree 802.1d
Rapid Spanning Tree (RSTP) 802.1w
Multiple Spanning Tree (MSTP) 802.1s
MAC Table
Up to 32K MAC addresses
Trunking
Link Aggregation Control Protocol (LACP) IEEE 802.3ad for any SFP+ or G.hn ports
VLAN
Supports up to 4K VLANs simultaneously (out of 4096 VLAN IDs)
•
Port-based VLAN
•
IEEE 802.1Q tag-based VLAN
•
IEEE 802.1ad (Q-in-Q) double tag VLAN
•
MAC-based VLAN
•
Management VLAN
•
Private VLAN Edge (PVE)
Generic VLAN
Registration (GVRP)
Protocols for automatically propagating and configuring VLANs in a Multicast Domain for
IPTV and other multicast services
IGMP v1/v2/v3
snooping
IGMP limits bandwidth-intensive multicast traffic to only the requesters
Supports 1024 multicast groups
IGMP Proxy
IGMP snooping with proxy reporting or report suppression actively filters IGMP packets to
reduce load on the multicast router
IGMP Query
IGMP query is used to support layer-2 multicast domain in the absence of a multicast
router
MLD v1/v2 snooping
Deliver IPv6 multicast packets only to the required receivers
DHCP Server
Supports DHCP server to assign addresses to IPv4 client devices
DHCP Snooping
DHCP snooping provides security by filtering un-trusted DHCP messages and by building
and maintaining a DHCP snooping binding table
DHCP Relay
By supporting DHCP option 82, it is possible to forward DHCP requests to another
specific DHCP server via DHCP relay. The DHCP server may be on another network
Layer-3 Support
IPv4 Static Routing
Static routing of IPv4 unicast traffic
IPv6 Static Routing
Static routing of IPv6 unicast traffic
