【正文】 Quota used ? Connection start time and duration ? The CSG_WAP_STATS record is generated at the conclusion of each connectionoriented WAP transaction ? Byte counts in the WAP Stats TLV reflect the total bytes for the transaction that begins with the reported WSP PDU type. For example, a GET begins a transaction that successfully concludes with an ACK to the final REPLY. The byte counts tally all IP bytes for these WAP packets and for ACKs belonging to this transaction. ? Multiple WAP transactions happen over a single UDP session. When the UDP session ends due to a DISCONNECT or an inactivity timeout, the CSG generates a summary UDP statistics record detailing byte counts for the entire UDP session. The statistics/info included depends on the WSP PDU type. 44 169。 2022 Cisco Systems, Inc. All rights reserved. Data Reported (for Generic TCP and UDP) TCP Record: ?
