Detailed Description

Create an EPC network with PointToPoint links.

Doxygen introspection did not find any typical Config paths.

This Helper will create an EPC network topology comprising of a single node that implements both the SGW and PGW functionality, and an MME node. The S1-U, X2-U and X2-C interfaces are realized over PointToPoint links.

Attributes

S1uLinkDataRate: The data rate to be used for the next S1-U link to be created
- Set with class: DataRateValue
- Underlying type: DataRate
- Initial value: 10000000000bps
- Flags: construct write read

- Flags: construct write read
S1uLinkMtu: The MTU of the next S1-U link to be created. Note that, because of the additional GTP/UDP/IP tunneling overhead, you need a MTU larger than the end-to-end MTU that you want to support.

Here is the caller graph for this function:

void ns3::PointToPointEpcHelper::DoDispose ( void )

virtual

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

Subclasses are expected to implement their real destruction code in an overriden 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.

Ptr< Node > ns3::PointToPointEpcHelper::GetPgwNode ( )

virtual

Returns: a pointer to the node implementing PGW functionality. Note that in this particular implementation this node will also hold the SGW functionality. The primary use intended for this method is to allow the user to configure the Gi interface of the PGW, i.e., to connect the PGW to the internet.
