Abstract: 본 발명은 UART 기반의 RF 통신장치 및 방법에 관한 것으로, RF 통신부를 복수개 구비하고, 각 RF 통신부에서 서로 다른 주파수 대역을 이용하여 신호를 송수신함으로써, 하나의 송신 신호에 대해 서로 다른 주파수 대역으로 신호를 전송하고, 서로 다른 주파수 대역으로부터 동일 데이터를 수신하여 무결한 데이터를 처리하도록 한다. 본 발명에 따르면, RF 환경을 사용하는 센서 네트워크 또는 무선환경 통신망에서 무결한 데이터를 무선환경으로 전송해야 할 경우 데이터의 깨어짐 없이 비교적 깨끗하게 데이터를 전송할 수 있는 이점이 있다. 특히, UART 방식으로 통신을 수행하는 RF 통신칩에 대해서 송신의 경우는 추가적인 소프트웨어 동작 없이 이중으로 데이터를 보낼 수 있는 효과가 있다.

Abstract: An apparatus and a method for selecting an optimal packet transmission path are provided to prevent loss of packets and keep the sequence of the packets by minimizing the change of existing path when adding or deleting the path. A field value extraction unit(110) extracts a field value corresponding a specified field of a packet which comes into a packet processing system supporting multi paths. A selecting path existence checkup unit transmits the packet if the corresponded field exists. If the path not exists, a path calculator(130) calculates a prime number which not exceeds the available number of paths and assigns the rest which is obtained by dividing the hash value into the next hop index. A path selecting unit(140) selects a search value which is obtained by searching for a hop index table by using the next hop index as a new path.

Abstract: An apparatus and a method for processing an Ethernet header are provided to implement an Ethernet processing function in a network communication device requiring a high speed process and to offer an Ethernet frame processing function to a router not having an Ethernet interface. An apparatus for processing an Ethernet header includes an input interface device receiving an Ethernet frame inputted from a medium access control framer. An Ethernet header analyzing device(230) analyzes the frame kind of the Ethernet frame received from the input interface device and extracts a destination and a source address. A filtering device(240) filters the destination and the source address extracted by the Ethernet header analyzing device. A frame check sequence checking device(250) checks the Ethernet frame filtered by the filtering device for data integrity. An Ethernet header removing device(260) removes the Ethernet header when a check result of the frame check sequence checking device is a normal state. An output interface device outputs a frame where the header is removed by the Ethernet header removing device to an upper processor.
