<p>PURPOSE:To prevent packet abolition state due to occupied buffer by providing an auxiliary route forming a bypass route to a first-in first-out buffer. CONSTITUTION:Routes 601, 602, 701, 702, 801 absorbing the overflow of buffer are provided. That is, the memory quantity of the 3rd buffer 10 is selected in matching with an average traffic and as a normal route, routes toward the 1st buffer 6, 1st bus 8, 3rd bus 10, 2nd bus 9 and 2nd buffer are given. If the traffic increase momentarily, the route absorbing the overflow of buffer is formed in parallel with the 3rd buffer 10 used for the normal route. Thus, the occurrence of packet abolition state due to the overflow packet is prevented.</p> |
