Unspecified bit rate (UBR): UBR services support non-real-time applications, such as file
transferring and Email. These applications have low requirements on delay or delay
changes.
Variable bit rate (VBR): VBR services can be further classified into real-time variable bit
rate (rt-VBR) services and non-real-time variable bit rate (nrt-VBR) services. Both rt-VBR
and nrt-VBR services support changeable (burst) cell transmitting rate at the source end.
The rt-VBR service type mainly applies to voice and video services.
Constant bit rate (CBR): The CBR service type usually applies to real-time services that
have high requirements on delay changes. Such services include voice, video, and circuit
emulation services.

Remarks
The LSR ID must be the same as the
IP address of the loopback interface
on the device. To differentiate
between the LSR ID and other IP
addresses, set the LSR ID to a
special unique value so that it
identifies the device intuitively.
The MPLS feature must be enabled
for:
1. Global
2. L2VPN
3. VLAN and VLAN interfaces
VLAN and VLAN interfaces must
be configured to enable MPLS
forwarding.
The control word adds control
information into service packets to
rearrange the packets and to prevent
packet disorder. ATM services must
use the control word since they have
high requirements on time sequence.
Cell concatenation enables a PW
packet to carry multiple ATM cells.
In this way, the transmission
efficiency of ATM cells over a PSN
network and bandwidth utilization
are improved.
