Receiving and transmitting devices for providing fragmentation at a transport level along a transmission path

A transmitting device, comprising:

• an interface;
• and
• a control unit communicatively coupled to the interface, the control unit adapted to:
• negotiate a packet size with a remote device to determine a size of data packets that is allowed to be transmitted to the remote device;
• transmit a data packet of up to the negotiated size, wherein the data packet includes a transport-level protocol packet encapsulated in a network-level protocol packet, and wherein the data packet includes a flag associated with the data packet that indicates the data packet should not be fragmented;
• and
• receive acknowledgments from the remote device associated with one or more fragments of the transmitted data packet, wherein the one or more fragments are fragmented at the transport-level protocol by a network device in response to determining that the size of at least one of the transmitted data packet and a fragment of that transmitted data packet is greater than an maximum transmission unit (MTU) value.
