Abstract:
[Problem] To allocate IFs to be used in accordance with buffers such that no packet loss occurs in a case in which the transfer apparatus that performs packet transfer includes as many buffers with grouped interfaces (IFs) mounted in units of groups thereon as the number of groups.[Solving Means] A packet transfer apparatus 10C has a plurality of buffers 11a to 11n mounting IFs in units of groups and performs, when the traffic amount at the time of packet transfer of the IFs of each of the buffers exceeds maximum transfer capacity of the IFs, buffering packets corresponding to the exceeding traffic amount in the buffers. An IF allocation unit 23 included in the transfer apparatus 10C selects, in a case in which IF groups with no occurrence of any loss indicating packet discarding are present at the time of the packet transfer in the IFs for a unit time from among all the IF groups, an IF group with a longest non-occurrence time of the buffering from among the IF groups with no occurrence of any loss and performs IF allocation of allocating traffic of packets to the IFs in the selected IF groups.
