Method Detail

start

protected void start(IP stack)

getInstance

public static LowPanUncompressed getInstance()

Return this LowPanUncompressed singleton

Returns:

the LowPanUncompressed singleton

getDefaultHops

public int getDefaultHops()

Returns the number of lowpan hops an IP broadcast packet is allowed to traverse

Returns:

the number of mesh hops a broadcast will traverse

setDefaultHops

public void setDefaultHops(int hops)

Sets the number of mesh hops the low pan packet will be allowed to traverse

Parameters:

hops - the number of allowable mesh hops for IP broadcast packets

setSubnetPrefix

public void setSubnetPrefix(byte[] prefix,
                            int size)

Sets the IPv6 subnet information for this link

Specified by:

setSubnetPrefix in interface IIPNetworkInterface

Parameters:

prefix - The IPv6 prefix associated with the interafce

size - The number of bits in the network portion (netmask bits)

getInterfaceName

public String getInterfaceName()

returns the name associated with this interface

Specified by:

getInterfaceName in interface IIPNetworkInterface

Returns:

sendPacket

public void sendPacket(IPv6Packet p)
                throws NetworkException

Send a packet via this interface to a node we expect to be on this link

Specified by:

sendPacket in interface IIPNetworkInterface

Parameters:

p - A properly formatted IPv6 packet

Throws:

NetworkException

sendPacket

public void sendPacket(IPv6Packet p,
                       IPRouteEntry re)
                throws NetworkException

Send an IP packet using this interface

Specified by:

sendPacket in interface IIPNetworkInterface

Parameters:

p - A properly formated IPv6 packet to send

re - A route entry that contains the next hop information

Throws:

NetworkException

getGlobalAddress

public byte[] getGlobalAddress()

Description copied from interface: IIPNetworkInterface

Return the IPv6 address associated with this interface

Specified by:

getGlobalAddress in interface IIPNetworkInterface

Returns:

The global IPv6 address associated with this interface

getSubnetSize

public int getSubnetSize()

Specified by:

getSubnetSize in interface IIPNetworkInterface

processIncomingData

public void processIncomingData(byte[] payload,
                                LowPanHeaderInfo headerInfo)

Description copied from interface: IProtocolManager

Called whenever data is received that is addressed to this IProtocolManager. IProtocolManagers should do as little processing as possible inside this method, to avoid blocking other INewProtocolManagers from receiving their packets. Typically an IProtocolManager will queue received packets for later dispatch to applications.

Specified by:

processIncomingData in interface IProtocolManager

getLinkLocalAddress

public byte[] getLocalSolicitedAddress()

Specified by:

getLocalSolicitedAddress in interface IIPNetworkInterface

getLinkLayerAddress

Description copied from interface: IIPNetworkInterface

returns the media specific link layer address

Specified by:

getLinkLayerAddress in interface IIPNetworkInterface

Returns:

a byte array in network byte order, with the link layer address

getSubnetPrefix

public byte[] getSubnetPrefix()

Returns a byte array representation of the IPv6 subnet prefix for this interface

Specified by:

getSubnetPrefix in interface IIPNetworkInterface

Returns:

The IPv6 prefix for this interface

getNeighborManager

public NeighborManager getNeighborManager()

returns the neighbor manager associated with this interface

Specified by:

getNeighborManager in interface IIPNetworkInterface

The NeighborManager for this interface

getServiceName

public String getServiceName()

Gets the name of this service

Specified by:

getServiceName in interface IService

Specified by:

getServiceName in class BasicService

Returns:

the service name
