Abstract:
1. A method for optimizing communications of a packet network, the method comprising: determining network performance information at a data link layer of a first network device, the network performance information being associated with user datagram protocol communications between the first network device and a second network device along a communications path, the network performance information enabled to describe a network problem including quality of service problems and, traffic problems for both real-time content and non-real-time content of the user datagram protocol communications; generating a packet, the packet including the network performance information; identifying a third network device as a nearest network device with transport layer capabilities for the user datagram protocol and as having available buffer space; communicating the packet to the third network device in response to identifying the third network device as the nearest network device with the transport layer capabilities for the user datagram protocol and as having the available buffer space; injecting the network performance information from the data link layer into a transport layer in response to detecting a network problem utilizing the network performance information in the packet; and controlling bandwidth of data communicated by the third network device utilizing the user datagram protocol in response to the network performance information in the communicated packet.
