A control apparatus is connected to another control apparatus that is connected to a network. The control apparatus acquires control information of another device controlled by the other control apparatus. The control apparatus, during control of the other device connected to the other control apparatus, executes a predetermined command having a format that is a same as that of an interface in the control apparatus and to which an identifier other than that of the control apparatus is appended, the control apparatus using a response from the other control apparatus as a result for the executed command.

A network interface controller including a data alignment module, a boundary determination module and a checksum module is provided. The data alignment module receives raw data and re-combines the raw data as first valid data, wherein the raw data includes a first layer protocol segment and a second layer protocol segment. The boundary determination module receives the raw data in parallel to the data alignment module and performs a boundary determination operation on the raw data to generate a boundary information indicating a boundary between the first layer protocol segment and the second layer protocol segment. The checksum module is coupled to the data alignment module and configured to disassemble the first valid data as second valid data and calculate a checksum according to the boundary information and the second valid data.

A network interface controller is provided, including a receiving module, a boundary determination module, a first checksum calculation module, and a second checksum calculation module. The receiving module receives a packet having a segment of a first layer protocol and a segment of a second layer protocol. The boundary determination module performs a boundary determination operation on the packet to generate boundary information, wherein the boundary information includes a length of the segment of the second layer protocol and a boundary indication signal. The first checksum calculation module finishes the calculation of a first checksum corresponding to the segment of the first layer protocol after receiving the length of the segment of the second layer protocol. The second checksum calculation module starts to calculate a second checksum corresponding to the segment of the second layer protocol after receiving the boundary indication signal.

A network device for processing various types of requests is proposed. The network device may store segment information of the various types of requests by using different registers, thereby the reliability of the subsequently generated response can be improved while increasing the efficiency of implementing the ARP/NDP offloading.
