Patent number: 8457012Abstract: Disclosed herewith is a packet transfer apparatus that carries out 1+1 protection switching for traffics to be received variably in both length and cycle. The apparatus enables flows to be multiplexed and the link usage efficiency to be improved without generating any buffer overflow errors. The data transfer apparatus, upon receiving the third sequentially numbered data from the first communication route before receiving the preceding second sequentially numbered data, stores the received third data in a buffer. And upon receiving the second sequentially numbered data from the second communication route, the apparatus sends the second and third data sequentially. Then, upon receiving the third sequentially numbered data from the second communication route before receiving the second sequentially numbered data, the apparatus sends the third data when a predetermined waiting time expires.Type: GrantFiled: March 10, 2008Date of Patent: June 4, 2013Assignee: Hitachi, Ltd.Inventors: Hideki Endo, Masayuki Takase, Shikou Matsushima, Akihiko Tanaka, Takayuki Kanno, Yoshihiro Ashi

Patent number: 8243745Abstract: A packet communication apparatus includes a frame buffer of a linked list method and holds chain information and buffer size information, for structuring a linked list buffer for each user flow, in two areas consisting of an operation area and an update area. While usually in service, the buffer is structured by using the chain information in the operation area and the buffer size information in the same area such that the frame is read/written in the frame buffer. When the chain information in the update area and the buffer size information in the same area have been changed, a queue size is changed by reflecting the updated chain information and the updater buffer size information into the operation area, when both the read pointer and the write pointer respectively have gone around the buffer, or when there is no frame stored in the buffer.Type: GrantFiled: February 3, 2010Date of Patent: August 14, 2012Assignee: Hitachi, Ltd.Inventors: Hideki Endo, Akihiko Tanaka, Takayuki Kanno, Masayuki Takase, Taisuke Ueta
