Detailed Description

class for the reordering buffer that keeps the data from lower layer, i.e. TcpL4Protocol, sent to the application

Member Function Documentation

bool ns3::TcpRxBuffer::Add	(	Ptr< Packet >	p,
		TcpHeader const &	tcph
	)

Insert a packet into the buffer and update the availBytes counter to reflect the number of bytes ready to send to the application. This function handles overlap by triming the head of the inputted packet and removing data from the buffer that overlaps the tail of the inputted packet

Returns:

True when success, false otherwise.

Ptr<Packet> ns3::TcpRxBuffer::Extract

(

uint32_t

maxSize

)

Extract data from the head of the buffer as indicated by nextRxSeq. The extracted data is going to be forwarded to the application.
