Detailed Description

Container of various random variables to assist in generating web browsing traffic pattern.

The available random values to be retrieved are:

MTU size — 536 bytes or 1460 bytes;
request size — constant 350 bytes;
delay in generating a main object — 0 second;
main object size — truncated LogNormal distribution with a mean of 10710 bytes;
delay in generating an embedded object — 0 second;
embedded object size (in bytes) — truncated LogNormal distribution with a mean of 7758 bytes;
number of embedded object per web page — truncated Pareto distribution with a mean of approximately 3.95 (after truncation);
length of reading time (in seconds) — unbounded exponential distribution with a mean of 30 seconds; and
length of parsing time (in seconds) — unbounded exponential distribution with a mean of 0.13 seconds.

Most parameters of the random distributions are configurable via attributes and methods of this class. The default values are according to the following references:

3GPP TR 25.892, "Feasibility Study for Orthogonal Frequency Division Multiplexing (OFDM) for UTRAN enhancement"
IEEE 802.16m, "Evaluation Methodology Document (EMD)", IEEE 802.16m-08/004r5, July 2008.

Constructor & Destructor Documentation

◆ ThreeGppHttpVariables()

ns3::ThreeGppHttpVariables::ThreeGppHttpVariables ( )

Create a new instance with default configuration of random distributions.

Definition at line 25 of file three-gpp-http-variables.cc.

References ns3::CreateObject(), m_embeddedObjectGenerationDelayRng, m_embeddedObjectSizeRng, m_mainObjectGenerationDelayRng, m_mainObjectSizeRng, m_mtuSizeRng, m_numOfEmbeddedObjectsRng, m_parsingTimeRng, m_readingTimeRng, m_requestSizeRng, and NS_LOG_FUNCTION.

Here is the call graph for this function:

Member Function Documentation

◆ AssignStreams()

int64_t ns3::ThreeGppHttpVariables::AssignStreams ( int64_t stream )

Assign a fixed random variable stream number to the random variables used by this model.

Different random variable stream number makes random number generators to produce different set of random values, thus possibly resulting to different simulation results. On the other hand, two identical simulations which use the same stream number should produce identical results (the repeatability property of ns-3 simulation).

Parameters

stream The first stream index to use.

Returns: The number of stream indices assigned by this model.

References m_embeddedObjectGenerationDelayRng, m_embeddedObjectSizeRng, m_mainObjectGenerationDelayRng, m_mainObjectSizeRng, m_mtuSizeRng, m_numOfEmbeddedObjectsRng, m_parsingTimeRng, m_readingTimeRng, m_requestSizeRng, and NS_LOG_FUNCTION.

◆ DoInitialize()

void ns3::ThreeGppHttpVariables::DoInitialize ( )

overrideprivatevirtual

Initialize() implementation.

This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.

Reimplemented from ns3::Object.

Definition at line 316 of file three-gpp-http-variables.cc.

References NS_LOG_FUNCTION, UpdateEmbeddedObjectMuAndSigma(), and UpdateMainObjectMuAndSigma().

Here is the call graph for this function:

◆ GetEmbeddedObjectGenerationDelay()

Time ns3::ThreeGppHttpVariables::GetEmbeddedObjectGenerationDelay ( )

Returns the constant length of time needed by an HTTP server to generate an embedded object.

By default, embedded objects are generated instantly, i.e., zero delay. This can be modified by setting the EmbeddedObjectGenerationDelay attribute or by calling the SetEmbeddedObjectGenerationDelay() method.

Returns: The delay for generating an embedded object.

Definition at line 225 of file three-gpp-http-variables.cc.

References m_embeddedObjectGenerationDelayRng, and ns3::Seconds().

Here is the call graph for this function:

◆ GetEmbeddedObjectSize()

uint32_t ns3::ThreeGppHttpVariables::GetEmbeddedObjectSize ( )

Draws a random embedded object size (in bytes) to be sent by an HTTP server.

The size of embedded objects are determined by a truncated log-normal random distribution. The default distribution settings produces random integers with a mean of 7758 bytes and a standard deviation of 126168 bytes, and then truncated to fit between 50 bytes and 2 MB. These default settings can be modified via attributes or class methods.

Returns: Embedded object size in bytes.

Definition at line 231 of file three-gpp-http-variables.cc.

References m_embeddedObjectSizeMax, m_embeddedObjectSizeMin, m_embeddedObjectSizeRng, and NS_FATAL_ERROR.

◆ GetMainObjectGenerationDelay()

Time ns3::ThreeGppHttpVariables::GetMainObjectGenerationDelay ( )

Returns the constant length of time needed by an HTTP server to generate a main object.

By default, main objects are generated instantly, i.e., zero delay. This can be modified by setting the MainObjectGenerationDelay attribute or by calling the SetMainObjectGenerationDelay() method.

Returns: The delay for generating a main object.

References m_mainObjectGenerationDelayRng, and ns3::Seconds().

Here is the call graph for this function:

◆ GetMainObjectSize()

uint32_t ns3::ThreeGppHttpVariables::GetMainObjectSize ( )

Draws a random main object size (in bytes) to be sent by an HTTP server.

The size of main objects are determined by a truncated log-normal random distribution. The default distribution settings produces random integers with a mean of 10710 bytes and a standard deviation of 25032 bytes, and then truncated to fit between 100 bytes and 2 MB. These default settings can be modified via attributes or class methods.

Returns: Main object size in bytes.

Definition at line 200 of file three-gpp-http-variables.cc.

References m_mainObjectSizeMax, m_mainObjectSizeMin, m_mainObjectSizeRng, and NS_FATAL_ERROR.

◆ GetMtuSize()

uint32_t ns3::ThreeGppHttpVariables::GetMtuSize ( )

Draws a random value of maximum transmission unit (MTU) size in bytes.

The possible MTU sizes are 1460 bytes and 536 bytes with 76% and 24% chances, respectively. The selected value is typically used by the sockets of HTTP servers to send the response packets (both main objects and embedded objects) to the requesting HTTP clients.

Returns: MTU size in bytes.

Definition at line 172 of file three-gpp-http-variables.cc.

References m_highMtu, m_highMtuProbability, m_lowMtu, m_mtuSizeRng, and NS_ASSERT.

◆ GetNumOfEmbeddedObjects()

uint32_t ns3::ThreeGppHttpVariables::GetNumOfEmbeddedObjects ( )

Draws a random integer indicating the number of embedded objects in a main object.

The number of embedded objects in a main object is typically discovered when the HTTP client is parsing the main object in question. This number is determined by a truncated Pareto distribution. The default distribution settings produces (after truncation) random integers within [0, 53) interval, with an actual mean of approximately 3.95.

Returns: The number of embedded objects.

Definition at line 256 of file three-gpp-http-variables.cc.

References m_numOfEmbeddedObjectsRng, m_numOfEmbeddedObjectsScale, and NS_FATAL_ERROR.

◆ GetParsingTime()

Time ns3::ThreeGppHttpVariables::GetParsingTime ( )

Draws a random length of time which simulate the small delay caused by HTTP client looking for any embedded objects within the received main object.

Parsing time is determined by an exponential distribution. The default distribution settings produces random values with a mean of 130 ms without any maximum bound. The mean can be modified by setting the ParsingTimeMean attribute or by calling the SetParsingTimeMean() method.

Returns: time interval for parsing a main object

Definition at line 292 of file three-gpp-http-variables.cc.

References m_parsingTimeRng, and ns3::Seconds().

Here is the call graph for this function:

◆ GetReadingTime()

Time ns3::ThreeGppHttpVariables::GetReadingTime ( )

Draws a random length of time which is spent by a hypothetical human user (HTTP client) to read a web page before transitioning to another web page.

Reading time is determined by an exponential distribution. The default distribution settings produces random values with a mean of 30 seconds without any maximum bound. The mean can be modified by setting the ReadingTimeMean attribute or by calling the SetReadingTimeMean() method.

Returns: Time interval for reading a web page.

Definition at line 286 of file three-gpp-http-variables.cc.

References m_readingTimeRng, and ns3::Seconds().

Here is the call graph for this function:

◆ GetRequestSize()

uint32_t ns3::ThreeGppHttpVariables::GetRequestSize ( )

Returns the constant HTTP request size in bytes.

By default, HTTP request size is 350 bytes, which can be modified by setting the RequestSize attribute or calling the SetRequestSize() method. This value applies to requests by HTTP client for main objects and embedded objects alike.

Returns: Request size in bytes.

Definition at line 188 of file three-gpp-http-variables.cc.

References m_requestSizeRng.

◆ GetTypeId()

TypeId ns3::ThreeGppHttpVariables::GetTypeId ( )
