Description
Select the linking protocol. EoA is the most popular with PPPoA a close second (used with
many legacy ISPs). Options are:
EoA: Ethernet over ATM.
l
PPPoA: Point-to-Point Protocol over ATM.
l
IPoA: Internet Protocol over ATM.
l
Select whether multiple protocols or only one protocol is carried per PVC (Permanent Virtual
Circuit). Options are:
LLC/ENCAPSULATION: (Available when PPPoA is selected as the
l
Control (LLC) encapsulation protocols used with multiple PVCs.
LLC/SNAP-BRIDGING: (Available when EoA is selected as the
l
carry multiple protocols in a single PVC.
LLC/SNAP-ROUTING: (Available when IPoA is selected as the
l
carry one protocol per PVC.
VC/MUX: Virtual Circuit Multiplexer creates a virtual connection used to carry one pro-
l
tocol per PVC.
Select the bit rate protocol. Options are:
UBR without PCR: Unspecified Bit Rate with no Peak Cell Rate, flow control or time syn-
l
chronization between the traffic source and destination. Commonly used with applic-
ations that can tolerate data / packet loss.
UBR with PCR: Same as above but with a Peak Cell Rate.
l
CBR: Constant Bit Rate relies on timing synchronization to make the network traffic pre-
l
dictable. Used commonly in Video and Audio traffic network applications.
NON Realtime VBR: Non Realtime Variable Bit Rate used for connections that transport
l
traffic at a Variable Rate. This category requires a guaranteed bandwidth and latency. It
does not rely on timing synchronization between the destination and source.
Realtime VBR: Realtime Variable Bit Rate. Same as the above option but relies on timing
l
and synchronization between the destination and source. This category is commonly
used in networks with compressed video traffic.
Minimum allowable rate (cells per second) at which cells can be sent on a ATM network. For no
shaping, enter -1 .
The algorithm used to schedule the queue behavior. VC scheduling is unique from Default
Queues. Options are:
Weighted Round Robin: Time slices are assigned to each process in equal portions and
l
in circular order, handling all processes without priority (also known as cyclic exec-
utive).
Weighted Fair Queuing: A data packet scheduling technique allowing different schedul-
l
ing priorities to be assigned to statistically multiplexed data flows. Since each data flow
has its own queue, an ill-behaved flow (that sent larger packets or more packets per
second than the others since it became active) will only affect itself and not other ses-
sions.
