Abstract: A multimode handset and method that includes a first communications path adapted to communicate using a mobile telephone communications protocol, a second communications path adapted to communicate using a local, cordless communications protocol, and a processing unit in communication with the first and second communications paths and configured to switch between the first and second communications path during a telephone call.

Abstract: A method for monitoring and optimizing performance of a packet network utilizing user datagram protocol including determining network performance information between a sending user datagram protocol network element and a receiving user datagram protocol network element; concatenating the network performance information into data packets; transmitting the data packets to at least one non-user datagram protocol network device having transport layer capabilities; and controlling bandwidth of the at least one non-user datagram protocol network device to optimize the network utilizing the user datagram protocol based on the network performance information in the data packets. A system for monitoring and optimizing performance of a packet network utilizing user datagram protocol is also included.

Abstract: A system and method for determining a call path to assign a call over a packet network. A call request may be received, and at least two potential call paths over a packet network over which a call associated with the call request may be placed may be determined. Network performance information associated with each node segment on the respective at least two potential call paths may be accessed. A value associated with each potential call path may be determined, where each value may be indicative of communications operations on each potential call path. A call path may be assigned to the call based on the determined values.

Abstract: A system for adjusting the window size of a TCP packet on a packet network including a sending network element in communication with a receiving network element for transmitting and receiving data packets between the sending network element and the receiving network element on the packet network, wherein at least one of the sending network element and the receiving network element is configured to determine network performance information of the packet network; concatenate the network performance information into the data packets; and adjust the window size of the TCP packet based on the network performance information. A method for adjusting the window size of a TCP packet on a packet network is also included.

Abstract: A system for monitoring and optimizing performance on a packet network with vector performance tables including a network element including an input/output (I/O) unit configured to communicate data packets with at least one other network element on the packet network the data packets including network performance information; a processing unit configured to receive the data packets from the at least one other network element; and a memory in communication with the processing unit and configured to store a vector performance table including a compilation of the network performance information contained in the data packets, the processor configured to process the data packets to store the network performance information in the vector performance table. A method for monitoring and optimizing performance on a packet network with vector performance tables is also included.

Abstract: A system for adjusting the window size of a TCP packet on a packet network including a receiving transport layer device configured to determine network performance information of the packet network; concatenate the network performance information into the data packets; adjust the window size of the TCP packet based on the network performance information; a non-transport layer device in communication with the receiving transport layer device for receiving the data packets; and a transport layer device in communication with the non-transport layer device, wherein the non-transport layer device forwards the data packets on to the transport layer device. A method for adjusting the window size of a TCP packet on a packet network is also included.
