* Charging Data Record, a record of a ( billing ) event produced by a data network element in 3GPP networks

Charging Data Function ( CDF ) addresses are used for offline billing and Online Charging Function ( OCF ) for online billing.

* Online charging: The S-CSCF talks to a Session Charging Function ( SCF ) which looks like a regular SIP application server.

* Offline Charging: All the SIP network entities ( P-CSCF, I-CSCF, S-CSCF, BGCF, MRFC, MGCF, AS ) involved in the session use the Diameter Rf interface to send accounting information to a CDF located in the same domain.

The CCF will collect all this information, and build a Call Detail Record ( CDR ), which is sent to the billing system ( BS ) of the domain. Each session carries an IMS Charging Identifier ( ICID ) as a unique identifier generated by the first IMS entity involved in a SIP transaction and used for the correlation with CDRs.

Under the 2008 Charging Order introduced on 15 November 2008, charges between 10pm and 6am were scrapped, but standard daytime rates increased from £ 1. 50 for cars.

* Universal Charging Solution, a proposed standard for cell phone chargers

Charging foes is kept as Ecco's standard attack, though the designers added a homing feature.

* Service Data Function ( SDF ) or Service Data Point ( SDP ) This is a database that contains additional subscriber data, or other data required to process a call.

SNA was made public as part of IBM's " Advanced Function for Communications " announcement in September, 1974, which included the implementation of the SNA / SDLC ( Synchronous Data Link Control ) protocols on new communications products:

Thus there came about the research for " Le problème de Cauchy pour les équations différentielles d ' un fluide général "; the idea that Prof. Hironaka called " the Nash blowing-up transformation "; and those of " Arc Structure of Singularities " and " Analyticity of Solutions of Implicit Function Problems with Analytic Data ".

Built on top of AppleTalk Session Protocol ( for legacy AFP over DDP ) or the Data Stream Interface ( for AFP over TCP ), it provides services for authenticating users ( extensible to different authentication methods including two-way random-number exchange ) and for performing operations specific to the Macintosh HFS filesystem.

As a result of 18 months of studies and discussions, SC16 adopted a layered architecture comprising seven layers ( Physical, Data Link, Network, Transport, Session, Presentation, and Application ).

In December 1992, the National Oceanographic Data Center ( NODC ) and WDC presented an initial proposal for the GODAR Project at the 14th Session of the Committee on International Oceanographic Data and Information Exchange ( IODE ) where it was approved.

In recognition of the success of the IOC Global Oceanographic Data Archaeological and Rescue Project ( GODAR project ), a proposal was presented at the 16th Session of the Committee on International Oceanographic Data and Information Exchange ( IODE ), which was held in Lisbon, Portugal, in October – November 2000, to establish the World Ocean Database Project.

Data is transmitted during an established session by Session Message packets.

Where reliability is required, the Session Data Transport sub protocol allows semi-reliability of only the latest value for a particular " channel ".

Such modification can be applied to the PDU ( Protocol Data Unit ), to the time relations between the exchanged PDUs, or both ( hybrid methods ).

In telecommunication, Advanced Data Communication Control Procedures ( or Protocol ) ( ADCCP ) is a bit-oriented data link layer protocol used to provide point-to-point and point-to-multipoint transmission of data frames that contain error control information.

The SP3D protocol specification was published by NIST, but designed by the Secure Data Network System project of the National Security Agency ( NSA ), IPsec AH is derived in part from previous IETF standards work for authentication of the Simple Network Management Protocol ( SNMP ).

In particular, the IETF WGs on IP over Cable Data Network ( IPCDN ) and IP over Digital Video Broadcasting ( DVB ) produced some standards applicable to cable modem systems, primarily in the areas of Simple Network Management Protocol ( SNMP ) Management Information Bases ( MIBs ) for cable modems and other networking equipment that operates over CATV networks.
