+      description: |
+        The packet delay budget is the maximum allowable one-way latency between the customer's device
+        and the gateway from the operator's network to other networks. By limiting the delay, the network
+        can provide an acceptable level of performance for various services, such as voice calls,
+        video streaming, and data.
+        The end-to-end or round trip latency will be about two times this value plus the latency not controlled

+
+        For 5G network the 3GPP specification TS 23.203 defines the packet error loss rate QCI attribute. It
+        describes the Quality of Service (QoS) Class Identifier (QCI) parameters used to
+        differentiate traffic classes in mobile networks, ensuring appropriate resource
+        allocation and performance for various services.
+
+        The packet error loss rate is one of the QCI attributes, providing information on the
+        acceptable packet loss rate for a specific traffic class. This attribute helps maintain
+        the desired performance level for services like voice calls, video streaming, or data
+        transfers within the 3GPP mobile network.

+      description: |
+        The jitter requirement aims to limit the maximum variation in round-trip
+        packet delay for the 99th percentile of traffic, following ITU Y.1540
+        standards. It considers only acknowledged packets in a session, which are
+        packets that receive a confirmation of receipt from the recipient (e.g.,
+        using TCP). This requirement helps maintain consistent latency, essential
+        for real-time applications such as VoIP, video calls, and gaming.
