INDEPENDENT MEASUREMENT EXPERT IDENTIFIED 
IN ACCORDANCE WITH AT&T-DIRECTV MERGER CONDITION
MB Docket No. 14-90
On July 24, 2015, the Commission approved the applications of AT&T Inc. and DIRECTV for 
consent to the transfer of control of various Commission licenses and other authorizations from 
DIRECTV to AT&T pursuant to Section 310(d) of the Communications Act of 1934, as amended.1 In 
order to address the potential harms posed and to confirm certain benefits offered by the transaction, the 
merged entity was subject to certain conditions imposed by the Commission as set forth at Appendix B of 
the Order.
Section V(2)(c) of Appendix B of the Order requires that, within 60 days of the closing date of 
the transaction, an Independent Measurement Expert be identified who will be responsible for 
establishing a schedule and the methodology for the merged entity to report certain performance 
characteristics of traffic exchanged at Internet Interconnection Points located within the United States, as 
described further in Appendix B of the Order.2
In accordance with Section V(2)(c)(i) of Appendix B of the Order, the Center for Applied Internet 
Data Analysis (“CAIDA”), a research group at University of California at San Diego, has been identified 
as the Independent Measurement Expert.  CAIDA is a collaborative undertaking among organizations in 
the commercial, government, and research sectors that aims to promote greater cooperation in the 
engineering and maintenance of a robust, scalable global Internet infrastructure.  CAIDA was identified 
as the Independent Measurement Expert by an agreement between AT&T and the Commission’s Office 
of General Counsel, which has approved the selection, as required by Section V(2)(c)(i) of Appendix B of 
the Order.  More information about CAIDA is available at www.caida.org.
