    • An apparatus includes a first switch circuit in an active mode and a second switch circuit in a standby mode. The apparatus receives high-priority packets and low-priority packets. Each switch circuit stores the high-priority packets and the low-priority packets into first and second buffers, respectively. The each switch circuit performs packet-readout processing reading out a packet from the first and second buffers where the packet-readout processing is performed on the first buffer on a priority basis. The apparatus controls the first switch circuit so that a back-pressure time for the high-priority packets becomes longer with increasing amount of data transmitted by the high-priority packets, when a low-priority packet outputted from the first switch circuit is determined to be a packet that has been received at a first time that is later than a second time at which another low-priority packet outputted from the second switch circuit has been received.

    • In a pipe forming process using bending rolls, load applied to an upper roll is reduced to suppress the deflection of the upper roll, thereby suppressing creation of large end gap at the longitudinal center of the pipe, thus enabling production of high-strength, thick-walled elongated pipes. This is achieved either by (1) setting the roll spacing L between lower rolls to a value greater than the sum of the diameter Dwu of the upper roll 34 and the diameter Dwl of each of the lower rolls 32, and setting the amount S of tightening of the upper roll 34 with respect to the lower rolls 32 to a value greater than the radius Rwl of each of the plural rolls; or by (2) effecting pipe forming work on the sheet material such that the spacing L of the lower rolls 32 satisfies the following condition: (Dp+Dwl)>L≧0.85(Dp+Dwl), where Dp represents the outside diameter of the product pipe and Dwl represents the diameter of one of the plural rolls; or by (3) preparing the sheet material having leading and trailing bent end regions bent beforehand over a length not smaller than ⅕ of the entire circumference of the pipe to be produced; and effecting bending by the bending rolls such that the length of the regions bent by the bending rolls is less than ⅗ the entire circumference of the pipe.
