Abstract: Systems and methods for a network diagnostic component that is placed in-line between two nodes in a network to control the protocol with which two nodes communicate. The network diagnostic component receives a network data stream from a first node for communication with a second node. The network data stream is received by a receive component or module. The network data stream includes a portion that conforms with at least a first network protocol. The diagnostic component then determines that the first network protocol is not to be used to communicate with the second node. This determination is performed by a determine component or module. The diagnostic component modifies the network data stream so that the network data stream is in a form that is no longer recognized by the second node as being in accordance with the first network protocol. The modification is performed by a modification component or module.

Abstract: A system and method of wireless communication power control is provided which allows for adjusting power levels without requiring high bandwidth for control. Embodiments allocate subcarriers into unequal power groups, each group having a consistent subcarrier power level. Using interference parameter information from a user, a subcarrier is assigned from a group having adequate power to maintain the user's required power level. In general, users with higher power requirements, such as those near cell boundaries, will be assigned subcarriers from a group having a higher power level. A cell may use a different allocation than a neighbor, so that subcarriers with the highest power level in one cell may not also have the highest power level in a neighboring cell. Such diversity may reduce inter-cell interference of the subcarriers near a cell boundary, since no two subcarriers are transmitted with highest power simultaneously by neighboring base stations.

Abstract: A method and apparatus for measuring network performance. A stream of packets of encoded data, sent by a transmitter across a network, are received. The stream of packets includes (n+1) packets having transmittal timestamps from a clock local to the transmitter, where n is an integer greater than or equal to one. An (n+1)th transmittal timestamp and an nth transmittal timestamp are determined. A value is calculated based on the (n+1)th and the nth transmittal timestamps. The value corresponds to the size of a virtual buffer needed to store the packets during a measurement interval. The value is used to determine a performance measure for the network.

Abstract: By introducing a novel parameter common to all links along the entire multihop route it is possible to more flexibly allocate, for each of a number of the links, a set of three interdependent link transmit parameters representative of link transmit energy, link transmit time or link transmit bandwidth or link code word consumption, and link transmit power. Basically, the common parameter is determined based on a given end-to-end (ETE) transmit parameter constraint for the entire multihop route. The idea is then to assign or allocate, for each considered link, the three interdependent link transmit parameters based on the common parameter and local link characteristics. In this way, all three link transmit parameters may (and generally will) be different between at least two links on the route when the links have different link characteristics, assuming that each link transmit parameter is also dependent on the local link characteristics.

Abstract: In a network wherein a data plane for communicating user data, and a control plane for managing data forwarders are configured of different media, the path teardown of the data plane which is forwarding the data is prevented when a fault has occurred in only the control plane. When the GMPLS controller of the control plane has detected refresh timeout with respect to an adjacent node (101 in FIG. 1), it checks whether or not a transmission equipment corresponding to a faulty controller has a fault (102), and it maintains a path state (103) in a case where the fault is limited to the control plane. Thus, the exchange of refresh messages with the adjacent node is continued without cleaning up the resources of the transmission equipment (104 through 107).
