interface.
Multiple PVC on single port
VigorAccess allows you to use different virtual connection also called PVC
(Permanent Virtual Circuits) for different services or subscribers. Users can define
up to 8 connections on each DSL port for different services or levels of service, and
users can assign different priority for each connection.
IGMP Snooping
IGMP (Internet Group Management Protocol) snooping reduces multicast traffic for
maximum performance. The feature is very popular for video multicast application
for example IPTV service.
Load-sharing Redundancy
These two Ethernet uplinks of VigorAccess can be used as a single load-shared
uplink for data and management path, with a provision to fall back to single one, in
the event one of the links failed.
Active Standby Redundancy
These two Ethernet uplinks of VigorAccess can be used in an active stand by mode
for data and management path, with a provision to fall back to standby link, in the
event of the active links failure.
Configuration
Modification of Ethernet IP address, mask, speed, and duplex mode is supported.
Support for safe mode boot where the TE Image can be downloaded for field
upgrade.

Quality of Service (QoS) refers to the capability of a network to provide better service to
select network traffic over various technologies. The primary goal of QoS is to provide
priority including dedicated bandwidth, controlled jitter and latency (required by some
real-time and interactive traffic), and improved loss characteristics. Also it is important to
make sure that providing priority for one or more flows does not make other flows fail.
QoS technologies provide the elemental building blocks that will be used for future
business applications in campus, WAN and service provider networks.
Prioritized Bridging
VigorAccess supports for multiple queues per port. There are different queues both
on ATM and Ethernet uplink.
Four queues supported per ATM port.
Eight queues supported per physical Ethernet port.
Scheduling Mechanism
VigorAccess supports multiple scheduling mechanisms.
Strict Priority Scheduling
Probabilistic Priority Scheduling
Rate Limiting
VigorAccess supports rate-limiting function in input/output both direction.
Input Rate Limiting (IRL) on a per-AAL5 interface.
Output Rate Limiting (ORL) on a per ATM-port basis
Output Rate Limiting (ORL) on a per-physical Ethernet Interface basis.
One feature supports for buffer admission control triggered using IRL.
