fn_NetSim_CR_BS_PackPacket()

NetSim_PACKET * fn_NetSim_CR_BS_PackPacket	(	BS_MAC *	pstruBSMac,
		NetSim_PACKET *	pstruPacket
	)

In the MAC, the transmitting side has full discretion whether or not to pack a group of MAC SDUs into a single MAC PDU. BSs and CPEs shall both have the capability of unpacking. If packing is turned on for a connection, the MAC may pack multiple MAC SDUs into a single MAC PDU. Also, packing makes use of the connection attribute indicating whether the connection carries fixed-length or variable-length packets.

Fragmentation is the process by which a MAC SDU is divided into one or more MAC PDUs. This process is undertaken to allow efficient use of available bandwidth relative to the QoS requirements of a connection’s service flow. Upon the creation of a connection by the MAC SAP, fragmentation capability is defined. Fragmentation may be initiated by a BS for downstream connections and by a CPE for upstream connections.
