Detailed Description

Implements a generic packet or fragment. Packets are generated in a PacketSource, can be stored in Server Queues, and are destroyed in Sinks.

Constructor & Destructor Documentation

Packet::Packet (  NetElement *  src, NetElement *  dst, unsigned int  bits, timeunits  stamp, unsigned long  datagramid = 0, unsigned int  totalbits = 0, unsigned int  k = 0 )

Constructor. Parameters: src  pointer to the source NetElement, typically a PacketSource dst  pointer to the destination NetElement, typically a PacketSink bits  packet size in bits. Has to be multiple of 8. stamp  generation time of the packet. datagramid  identifies the original packet a fragment packet belongs to. totalbits  datagram size in bits. Has to be multiple of 8. k  puts the packet in the k-th hop alogn the route from src to dst.

Member Function Documentation

unsigned int Packet::GetBits (  void   )  const

Returns: the size, in bits, of this packet or fragment.

unsigned long Packet::GetDatagramId (  void   )  const

Returns: the original packet identifier.

NetElement * Packet::GetDst (  void   )  const

Returns: pointer to the destination NetElement

unsigned long int Packet::GetPacketId (  void   )  const

Returns: the packet or fragment unique identifier.

unsigned int Packet::GetPos (  void   )  const

Returns: current position of this packet along the route from src to dst, in number of hops

NetElement * Packet::GetSrc (  void   )  const

Returns: pointer to the originating NetElement

timeunits Packet::GetStamp (  void   )  const [inline]

Returns: the origination time of the packet.

unsigned int Packet::GetTotalBits (  void   )  const

Returns: the size, in bits, of the original packet, before any fragmentation.

void Packet::Jump (  void   )

Advances the packet to the next hop to dst.

void Packet::SetBits (  unsigned int  b  )

Modifies this fragment size. Parameters: b  fragment size in bits.
