Detailed Description

Model application which simulates the traffic of a web server.

This application works in conjunction with ThreeGppHttpClient applications.

The application works by responding to requests. Each request is a small packet of data which contains ThreeGppHttpHeader. The value of the content type field of the header determines the type of object that the client is requesting. The possible type is either a main object or an embedded object.

The application is responsible to generate the right type of object and send it back to the client. The size of each object to be sent is randomly determined (see ThreeGppHttpVariables). Each object may be sent as multiple packets due to limited socket buffer space.

To assist with the transmission, the application maintains several instances of ThreeGppHttpServerTxBuffer. Each instance keeps track of the object type to be served and the number of bytes left to be sent.

The application accepts connection request from clients. Every connection is kept open until the client disconnects.

Constructor & Destructor Documentation

◆ ThreeGppHttpServer()

ns3::ThreeGppHttpServer::ThreeGppHttpServer ( )

Creates a new instance of HTTP server application.

After creation, the application must be further configured through attributes. To avoid having to do this process manually, please use ThreeGppHttpServerHelper.

Upon creation, the application randomly determines the MTU size that it will use (either 536 or 1460 bytes). The chosen size will be used while creating the listener socket.

◆ DoDispose()

void ns3::ThreeGppHttpServer::DoDispose ( void )

protectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

◆ ServeFromTxBuffer()

uint32_t ns3::ThreeGppHttpServer::ServeFromTxBuffer ( Ptr< Socket > socket )

private

Creates a packet out of a pending object in the Tx buffer send it over the given socket.

If the socket capacity is smaller than the object size, then the method only convert a part of the object into a packet.

ThreeGppHttpHeader will be attached in the beginning of each application layer packet - if a packet is split, then then the following parts will not have the header. The method fires the Tx trace source after sending the packet to the socket.

This method is invoked when a new object is generated by ServeNewMainObject() or ServeNewEmbeddedObject(). It's also invoked when the socket informs (through SendCallback()) that more buffer space for transmission has become available.

Parameters

socket Pointer to the socket which is associated with the destination client.

Returns: Size of the packet sent (in bytes).
