Based on this information, the rendezvous system identifies a server within a CDN from which the requested content may be retrieved. The selected server may be based on a repeatable hash function such that the likelihood that the content being requested is cached at the selected server. Steering requests to a server of the CDN which may have the content cached may reduce the number of servers within the CDN with the same cached content, particularly for the highest requested content. The rendezvous system may then return a corresponding domain name associated with the selected server and that can be subsequently submitted to a DNS for resolution to the IP address of the identified server. |

Dynamically biased power amplification
One example includes a device that is comprised of a pre-power amplifier, a power amplifier, a signal path, and a dynamic bias circuit. The pre-power amplifier amplifies an input signal and outputs a first amplified signal. The power amplifier receives the first amplified signal and amplifies the first amplified signal based on a dynamic bias signal to produce a second amplified signal at an output thereof. The signal path is coupled between an output of the pre-power amplifier and an input of the power amplifier. The dynamic bias circuit monitors the first amplified signal, generates the dynamic bias signal, and outputs the dynamic bias into the signal path. |

Method and device for controlling power amplification
A method and network equipment for controlling power amplification are disclosed. The method for controlling power amplification includes outputting a voltage signal according to the state of network equipment. When the network equipment is in an idle state, at least one power amplifier transistor is switched off according to a voltage signal. |
