Detailed Description

Implement the data structure representing a TrafficFlowTemplate Packet Filter. See 3GPP TS 24.008 version 8.7.0 Release 8, Table 10.5.162/3GPP TS 24.008: Traffic flow template information element

With respect to the Packet Filter specification in the above doc, the following features are NOT supported:

• IPv6 filtering (including flow labels)
• IPSec filtering
• filter precedence field is not evaluated, hence it is recommended to setup the TFTs within a PDP context such that TFTs are mutually exclusive

Member Function Documentation

bool ns3::EpcTft::PacketFilter::Matches	(	Direction	d,
		Ipv4Address	ra,
		Ipv4Address	la,
		uint16_t	rp,
		uint16_t	lp,
		uint8_t	tos
	)

Parameters

d	the direction
ra	the remote address
la	the local address
rp	the remote port
lp	the local port
tos	the type of service

Returns

true if the parameters match with the PacketFilter, false otherwise.
