     +{{indexmenu_n>5}} 
     + 
     +FastPCRF passes the following attributes within the Accounting-Request: 
     + 
     +''VasExperts-L2-SubsId'' – L2-subscriber ID. 
     + 
     +''Framed-IP-Address'' – (for the IPv4 only) is the subscriber IPv4 address; in case of NAT 1:1, this attribute value can be [[en:dpi:bras_bng:radius_integration:radius_accounting:radius_attr:framed_ip_address|configured]]. 
     + 
     +''Framed-IPv6-Prefix'' - (for the IPv6 only) IPv6 subscriber subnet prefix. 
     + 
     +''Framed-IPv6-Address'' - (for the IPv6 only) IPv6 subscriber address. Only high bits of the IP address are most significant, as specified by the IPv6 prefix. For example, for the prefix 2001:1::/64, the value of this attribute is 2001:1::. 
     + 
     +''Acct-Session-Id'' – RADIUS accounting session identifier. 
     +   
     +''Acct-Status-Type'' – the request type:  
     +    * [1] start – beginning of the accounting session. Statistics are not transmitted within this request, the only session id is transferred; 
     +    * [2] stop – termination of the accounting session. This request contains the final session statistics; 
     +    * [3] interim-update – interim statistics. 
     + 
     +''Acct-Delay-Time'' - is the timeout in seconds between receiving the last billing netflow statistics from the fastdpi and sending this Accounting-Request. In fact, this is a measure of data "obsolescence". 
     + 
     +''Class'' - if during authorization the Access-Accept/Access-Reject contains the Class attribute, then it will be transferred in all the accounting requests. 
     + 
     +''NAS-Port-Type'', ''NAS-Port'', ''NAS-IP-Address'', ''NAS-Identifier'' – are formed similarly to the [[en:dpi:bras_bng:radius_integration:radius_auth_server_integration|Access-Request]]. 
     + 
     +Statistics (accounting data) are defined in the [[https://tools.ietf.org/html/rfc2866|RFC-2866]] and are passed only for Acct-Status-Type= 2 or 3: 
     +  * ''Acct-Input-Packets'' - the number of packets sent to the subscriber (inet -> subs direction) 
     +  * ''Acct-Output-Packets'' - number of packets from the subscriber (subs -> inet direction) 
     +  * ''Acct-Input-Octets'' - number of bytes sent to the subscriber (inet -> subs direction) 
     +  * ''Acct-Output-Octets'' - number of bytes from the subscriber (subs -> inet direction) 
     +  * ''Acct-Input-Gigawords'' ([[https://tools.ietf.org/html/rfc2869|RFC-2869]])  
     +  * ''Acct-Output-Gigawords'' ([[https://tools.ietf.org/html/rfc2869|RFC-2869]]) 
     + 
     +in addition, statistics on the cs0-cs7 [[en:dpi:dpi_options:use_cases:qs_rateplans|traffic classes]] are transmitted in  vendor-specific-attributes (VSA). 
     +The following VSAs are defined for the vendor-id=43823: 
     +<code bash> 
     +ATTRIBUTE VasExperts-Acct-Traffic-Class-Name            16 string 
     +ATTRIBUTE VasExperts-Acct-Traffic-Class-Input-Octets    17 integer64 
     +ATTRIBUTE VasExperts-Acct-Traffic-Class-Output-Octets   18 integer64 
     +ATTRIBUTE VasExperts-Acct-Traffic-Class-Input-Packets   19 integer64 
     +ATTRIBUTE VasExperts-Acct-Traffic-Class-Output-Packets  20 integer64 
     +</code> 
     + 
     +here the ''VasExperts-Acct-Traffic-Class-Name'' is the traffic class name, "cs0", "cs1", ..., "cs7",  
     +the rest attributes contain statistics for this traffic class. Below is the example pf the packet (only the first two traffic statistics are unfolded): 
     +<code bash>
