Ptm Interface - SmartRG SR350N User Manual

Field Name Description
[UBR without PCR] Unspecified Bit Rate with no Peak Cell Rate, flow control or time synchronization between the traffic
source and destination. Commonly used with applications that can tolerate data / packet loss.
[UBR with PCR] Same as above but with a Peak Cell Rate.
[CBR] Constant Bit Rate relies on timing synchronization to make the network traffic predictable. Used commonly in Video
and Audio traffic network applications.
Service Category
[NON Realtime VBR] Non Realtime Variable Bit Rate used for connections that transport traffic at a Variable Rate but
need to have a guaranteed bandwidth and latency. This category does not rely on timing synchronization between the
destination and source.
[Realtime VBR] Realtime Variable Bit Rate. Same as above but relies on timing and synchronization between the
destination and source. Commonly used in networks with compressed video traffic.
[cells/s] (-1 indicates no shaping)
Minimum Cell Rate
Minimum allowable rate at which cells can be sent on a ATM network.
The algorithm used to schedule the queue behavior.
Scheduler for
[WRR] Weighted Round Robin packets are accessed in a round robin style and classes can be given.
Queues of Equal [WFQ] Weighted Fair Queuing packets are assigned in a specific queue.
Default Queue Weight [1-63] The default weight of the specified queue.
Precedence as the
Default Queue Precedence [1-8] The Precedence of the specified group.
Default Queue
VC scheduling is unique from Default Queues.

PTM Interface

The SmartRG gateway's VDSL2 standards support Packet Transfer Mode (PTM). An alternative to ATM mode, PTM transports packets (IP, PPP,
Ethernet, MPLS, and others) over DSL links. Reference the IEEE802.3ah standard for Ethernet in the First Mile (EFM) for additional information.
After selecting Advanced Setup -> Layer2 Interface -> PTM Interface
screen will appear.
