Detailed Description

Defines the TCP option of kind 4 (selective acknowledgment permitted option) as in RFC 2018

Introspection did not find any typical Config paths.

TCP Sack-Permitted Option is 2-byte in length and sent in a SYN segment by a TCP host that can recognize and process SACK option during the lifetime of a connection.

No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 32 bytes (on a 64-bit architecture).

Member Function Documentation

◆ Deserialize()

uint32_t ns3::TcpOptionSackPermitted::Deserialize ( Buffer::Iterator start )

virtual

Deserialize the Option from a buffer iterator.

Parameters

start the buffer iterator

Returns: the number of deserialized bytes

Implements ns3::TcpOption.

Definition at line 82 of file tcp-option-sack-permitted.cc.

Here is the call graph for this function:

◆ GetInstanceTypeId()

TypeId ns3::TcpOptionSackPermitted::GetInstanceTypeId ( void ) const

virtual

Get the most derived TypeId for this Object.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.
