1 Scope
The offer of new NGN services requires new KPIs, QoS measurement and benchmarking methods which are needed to
ensure the quality of new services. To ensure the comparability of test results, reference benchmarking methods and
background traffic load profiles are needed. The present document describes key performance indicators and
benchmarking methods for the spectrum of potential applications. All access technologies offered by the operator under
test are considered.
The present document is the second part of the multi-part deliverable which consists of four parts. The present
document contains the Reference benchmarking and KPIs for High speed internet.

4.1 PING
4.1.1 PING Packets Missing [%]
The parameter value "PING Packets Missing" indicates the ratio in percentage of ICMP echo replies not received to the
total number of initiated ICMP echo requests. An ICMP echo reply is deemed not received if it does not arrive within
the timeout of 10 seconds from an ICMP echo request.
ETSI

number of ICMP echo replies not received
PING Packets misssing % = ×100

total number of ICMP echo replies received
4.1.2 PING Packet Errors [%]
The parameter value PING Packet Errors indicates the percentage ratio of ICMP echo replies with errors to the total
number of ICMP echo replies received.
number of ICMP echo errors received
PING Packets Errors % = ×100
total number of ICMP echo replies received

4.1.3 PING Failure Ratio [%]
The parameter value PING Failure Ration represents the PING Failure Ratio as a percentage.
A PING measurement is considered unsuccessful if ICMP echo replies are missing, have errors (e.g. the target does not
respond with the same value in the "Sequence Number"), or the mean response time (PING Average Time) exceeds
1 second.
unsuccessfull IMCP requests
PING Failure Ratio % = ×100

4.2 HTTP
4.2.1 HTTP Response Time
The HTTP Response Time is defined as the time elapsed between the sending of the initial Sending of First TCP SYN
and the receipt of the first HTTP GET command. To determine the various HTTP download parameters of the products,
a standardized HTTP download to data reference systems is performed. In addition, four HTTP streams are set up in
parallel. These HTTP downloads access sufficiently large files, the download of which is simultaneously interrupted
after a defined period of time.
In this way, four HTTP Response Times are recorded per standardized HTTP download. The minimum value of the
HTTP Response Times recorded is deemed the HTTP Response Time of the standardized HTTP download.
4.2.2 HTTP Download Throughput
NOTE: Following the testing specified and results presented in Recommendation ITU-T Y.1540 [3], this metric
should not be used to measure access performance (using TCP transport). TCP throughput measurements
tend to under-estimate the network operator's access performance.
A standardized HTTP download is conducted to determine the available downstream bandwidth. The average
throughput is measured from opening the data connection to the end of the successful transfer of the content.

NOTE: There are web pages that do not have a well-defined last data packet, e.g. due to dynamic content. If such
pages are used for measurement, then suitable end of page indications, e.g. provided by the browser, may
be used as an alternative.
4.2.3 HTTP Download Throughput [%] of Bandwidth
The value HTTP Download Throughput [%] of Bandwidth is the percentage ratio of the reduced HTTP downloads to
the HTTP downloads undertaken in total.
ratio of the reduced HTTP downloads
HTTP Download Throughput % = ×100
HTTP downloads undertaken in total

4.2.4 HTTP Percentage of invoiced Bandwidth [%]
The HTTP Percentage of invoiced Bandwidth indicates the ratio in percent of the actual measured HTTP download
throughput against the nominally invoiced bandwidth.

HTTP invoiced bandwith % = ×100

4.2.5 HTTP Upload Response Time
The HTTP Upload Response Time is defined as the time elapsed between the sending of an initial HTTP request (GET
HTTP) to the receipt of the first HTTP Response Packet (TCP Packet).
4.2.6 HTTP Upload Throughput
The HTTP upload throughput is defined as the available upstream bandwidth in kbit/s.
NOTE: Following the testing specified and results presented in Recommendation ITU-T Y.1540 [3], this metric
should not be used to measure access performance (using TCP transport). TCP throughput measurements
tend to under-estimate the network operator's access performance.

15 ETSI TS 103 222-2 V1.2.1 (2019-08)
4.2.7 HTTP Upload Throughput [%] of Bandwidth
The value HTTP Upload Throughput [%] of Bandwidth is the percentage ratio of the reduced HTTP uploads to the
Nominal invoiced bandwidth.

4.2.8 Number of HTTP Sessions
Number HTTP Sessions is defined as a number of HTTP flows grouped together as per the heuristics below in order to
comprise the view of a unique web page.
4.2.9 HTTP Dropped Sessions [%]
The number percentage of HTTP Dropped Sessions indicates the ratio between the dropped file DL/UL connections and
the total file DL/UL Sessions
HTTP dropped sessions

4.2.10 HTTP Download Failure Ratio [%]
The HTTP Download Failure Ratio is defined as the ratio of failed HTTP downloads to the total number of initiated
HTTP downloads as a percentage.

HTTP download Faillure Ratio = ×100
total number of initiated HTTP downloads
4.2.11 HTTP peak download throughput
The definition of HTTP peak download throughput is for FFS.
4.3 FTP
4.3.1 FTP Upload/Download Throughput
The FTP Upload/Download Throughput determines the available upstream/downstream bandwidth.
NOTE: Following the testing specified and results presented in Recommendation ITU-T Y.1540 [3], this metric
should not be used to measure access performance (using TCP transport). TCP throughput measurements
tend to under-estimate the network operator's access performance.
