Number of bearer contexts : 1
What are the QCI/ARP values assigned to the bearer?
The dedicated bearer is assigned a QCI/ARP value of 2/12.
Is this a GBR bearer or a Non-GBR bearer? Why?
This is a GBR bearer as it has a QCI value of 2.
How many SDFs are assigned to this bearer?
There are 2 SDFs assigned to this dedicated bearer.
What are the MBR/GBR values assigned to the first SDF in the downlink direction?
The DL MBR/GBR values assigned for the first SDF are 1500/1000 Kbps.
10. Based on which QoS parameters does the PGW rate limit this dedicated bearer?
This is a GBR bearer; hence it will be rate-limited on the PGW based on the bearer level
MBR/GBR values.
What is maximum rate that the UE can send over this bearer in the DL direction?
The DL MBR/GBR values for this bearer are calculated as the sum of DL MBR/GBR for each
SDF, hence the bearer level DL MBR/GBR are 3500/2500 Kbps. In the downlink direction,
the UE can send up to 3500 Kbps. The rate up to 2500 is treated as in-profile, and the rate
between 2500 and 3500 is treated as out-of-profile.
11. In the downlink direction, which QCI policy is used for the dedicated bearer?
The dedicated bearer is connected to the ipd.alcatel-lucent.com. In the downlink direction,
the QCI policy  dl-qci-pl is used.
12. Some ftp traffic is sent from the PDN towards the UE. Over which bearer is this ftp traffic
forwarded?
The DL ftp traffic matches filter id 0, hence it will be forwarded over the dedicated bearer.
13. Which FC value is assigned to the ftp traffic received from the PDN? Which DSCP value is
assigned to this traffic when it is sent over the s5 interface towards the SGW?
The ftp traffic is mapped to the SDF associated with the dedicated bearer. This bearer is
established with QCI/ARP of 2/12. The  QCI 2 ARP 12 entry in the  dl-qci-pl is used for
marking, hence this DL traffic is assigned an FC value of  h2 and is marked with a DSCP
value of  af41 .

uses queue 5. Verify the statistics for port 1/1/1 to ensure that the ftp traffic is egressing on
queue 5.
