摘要:
A congestion control system is provided with a plurality of reaction points, each of which is configured to transmit a packet to a transmission destination; and a congestion point configured to receive the packets transmitted from the plurality of reaction points. When detecting congestion in itself, the congestion point samples each of the received packets based on a predetermined algorithm, and transmits a feedback message to the reaction point as a transmission source of the sampled packet. Each of the plurality of reaction points controls a target rate based on a reception situation of the feedback message, and sets the target rate to an initial value at an initialization timing which does not depend on the feedback message.
摘要:
An image forming apparatus is provided which ensures proper image forming when the apparatus is positioned either horizontally or upright. The apparatus includes a rotary, endless latent image carrier, and a latent image forming arrangement for forming a latent image on the latent image carrier. The apparatus also includes a developing arrangement for developing the latent image on the latent image carrier by using powdered developer, and a transferring arrangement for transferring a developed image on the latent image carrier to a sheet. The apparatus further includes a positioning mechanism for selectively positioning the developing arrangement relative to the latent image carrier at one of a first position corresponding to an upright installation of the apparatus and a second position corresponding to a horizontal installation of the apparatus.
