Abstract

A multilane transmission device that transmits data frames by using a plurality of lanes, comprising: a data frame allocating unit that allocates data frames based on a transmission destination; a flow group information sequence information adding unit that adds flow group information indicating a flow group corresponding to a transmission source and transmission destinations and sequence information indicating a sequence of the data frames to the data frames allocated based on each transmission destination by the data frame allocating unit; and a lane selecting/outputting unit that transmits the data frames having the respective flow group information and the respective sequence information added thereto by the flow group information sequence information adding unit to the transmission destinations by using one or more lanes corresponding to the respective flow group information.

Claims6

Dependent claims

A multilane transmission device that transmits data frames by using a plurality of lanes, comprising:

a data frame allocating unit that refers to a setting table which determines a flow group and a lane group for each of a plurality of transmission destinations, specifies the flow group corresponding to a transmission destination in the plurality of transmission destinations, and allocates data frames to one or a plurality of flows included in the specified flow group;
a buffer memory that stores data frames for each of the flows;
a data frame reading unit that refers to the setting table and reads each flow stored in the buffer memory for each flow group;
an encoding unit that encodes the data frames for each flow group read by the data frame reading unit;
a data string dividing unit that divides the data frames into data blocks having a certain length for each of the flows;
flow group information sequence information adding unit that adds flow group information indicating the flow group and sequence information indicating a sequence of the data blocks, to a data block;
a transmission frame processing unit that converts each data block, to which the flow group information and the sequence information are added, to a transmission frame;
and
a lane selecting/outputting unit that transmits the transmission frame to a transmission destination of the plurality of transmission destinations, by using one or a plurality of lanes included in the lane group according to the flow group determined by the setting table.
