Patent ID: 8774193

Claim:
A method for data transmission in a network device having a multi-layer structure, comprising: providing a plurality of pipelines, each pipeline having a specific assigned transmission rate; the plurality of pipelines transmitting a plurality of data in parallel between at least a first layer and a second layer of the multi-layer structure according to a data type of each data; processing the plurality of data respectively transmitted via the plurality of pipelines according to a plurality of AS (access stratum) protocols having varying transmission rates; determining a priority of each data according to the data type of each data; and processing a first data among the plurality of data according to a first AS protocol among the plurality of AS protocols and processing a second data among the plurality of data according to a second AS protocol among the plurality of AS protocols, wherein the first AS protocol is faster than the second AS protocol when it is determined that a priority of the first data is higher than a priority of the second data.
