createS1uFrom

public static UpfInterface createS1uFrom(Ip4Address address)

Create a core-facing UPF Interface from the given address, which will be treated as a /32 prefix.

Parameters:

address - the address of the new core-facing interface

Returns:

a new UPF interface

createUePoolFrom

public static UpfInterface createUePoolFrom(Ip4Prefix prefix)

Create a core-facing UPF Interface from the given IP prefix.

Parameters:

prefix - the prefix of the new core-facing interface

Returns:

a new UPF interface

createDbufReceiverFrom

public static UpfInterface createDbufReceiverFrom(Ip4Address address)

Create a dbuf-receiving UPF interface from the given IP address.

Parameters:

address - the address of the dbuf-receiving interface

Returns:

a new UPF interface

prefix

public Ip4Prefix prefix()

Get the IP prefix of this interface.

Returns:

the interface prefix

isAccess

public boolean isAccess()

Check if this UPF interface is for packets traveling from UEs. This will be true for S1U interface table entries.

Returns:

true if interface receives from access

isCore

public boolean isCore()

Check if this UPF interface is for packets traveling towards UEs. This will be true for UE IP address pool table entries.

Returns:

true if interface receives from core

isDbufReceiver

public boolean isDbufReceiver()

Check if this UPF interface is for receiving buffered packets as they are released from the dbuf buffering device.

Returns:

true if interface receives from dbuf

getPrefix

public Ip4Prefix getPrefix()

Get the IPv4 prefix of this UPF interface.

Returns:

the interface prefix
