Abstract: The disclosure relates to technology for determining stress on integrated circuits. These include using ring oscillators formed on the integrated circuit, where one ring oscillator has its frequency dependent on the current flowing through its stages being limited by its NMOS devices and another ring oscillator has its frequency dependent on the current flowing through its stages being limited by its PMOS devices. This allows the stress on the integrated circuit to be determined in different directions along the integrated circuit. A temperature sensor can be used to compensate for temperature dependence on the frequencies of the ring oscillators.

Abstract: Embodiments of the present invention disclose a service optimization method, a transport controller (TC), a client controller (CC), and a service optimization system. The method includes: receiving, by a TC, an optimization request from a CC; sending, by the TC, an answer message to the CC when determining that an idle resource in a resource pool can meet an optimization requirement of the CC; receiving, by the TC, an optimization instruction of the CC; and optimizing, by the TC according to the optimization policy in the optimization instruction, the service identified in the optimization instruction. When an idle network resource in the resource pool can meet the optimization requirement of the CC, the TC executes the optimization policy that meets the optimization requirement of the CC, so as to reduce a service interruption phenomenon in a service optimization process.
