A modulator bias selection method, a coherent optical transmitter, and optical modulator solve the problem of generating a correct constellation using the bias points with the minimum phase adjustment range. The optimum modulator bias systems and methods include a coherent optical transmitter with control of four (XI, XQ, YI, YQ) quadrature data signals via a transmitter (Tx) application specific integrated circuit (ASIC), with a modulator bias controller which implements an algorithm to find the optimum bias points. The optimum bias points yield a correct constellation with minimum phase / bias adjustment. An algorithm is used to find the optimum bias solution using fast, simple method, adjusting only one quadrature at a time and exploiting a control feature of the Tx ASIC. This algorithm is significantly simpler than a generalized search, is a local algorithm, and uses only DC power measurement at the transmitter.

A policy enforcement point (PEP) attaches to the edge of a packet-switched network to manage loading when the network nears or exceeds its capacity due to changes in the network, e.g., component failures or incremental growth. Autonomous PEP's at the network's edges provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. Changes become necessary when a network event results in a loss of resilient bandwidth that effects the traffic class under admission control. Or, when an unexpected surge in traffic exceeds the PEP's reserved resources to a particular destination. The resources available across the network are recalculated for minimizing impact on existing sessions or calls, and it informs the PEP's of the new resources available. If the new maximum exceeds the current utilization to that destination, the PEP invokes a local priority drop mechanism to back off the traffic until it is under the new limit. A media gateway handling voice calls can keep all emergency calls up, and then invoke a local algorithm, such as random drop, for the remaining calls until calls to the constrained destination are under the new limit. In the second case, where there is an unexpected surge in demand, the PEP can request from the bandwidth manager additional resources to a particular destination.

Provided is an optimized system voltage control method through coordinated control of reactive power source, which analyzes the location for reactive power compensation and the effect of applying compensation equipment by calculating the reactive power and voltage sensitivity of a power system, thus improving the voltage quality of the power system. The optimized system voltage control method includes verifying a voltage violation substation having a voltage exceeding a predetermined voltage reference value among buses of a test system on a computer program, configuring a local system with eight to ten substations with respect to the verified voltage violation substation, generating a reduced local system using a reduced local algorithm with respect to the buses within the configured local system, calculating a power flow by determining a voltage control amount for restoring the voltage of the voltage violation substation to a normal value with respect to the reduced local system, and calculating an optimization objective function value based on the voltage control amount and control operation.
