Abstract

본 발명은 ATM 망으로부터 신호적응계층을 통해 수신된 셋업(SETUP)메세지를 메모리에 저장한 후 카운터를 이용하여 상기셋업 메세지에 저장된 BLLI 정보요소를 찾아 윈도우 사이즈를 식별하기 위한 방법에 관한것으로, 상기 셋업 메세지의 길이 정보(Ls)를 구하는 제 1단계: 상기 카운터의 카운트값을 증가시키면서 9510와 비교하여 BLLI정보요소를 구하는 제2단계: 상기 카운터값이 상기 메세지 길이를 초과하는지 비교하여 에러를 검출하는 제3단계: 상기 BLLI 정보요소로부터 사용자정보 계층 2 프로토콜(UIL2) 데이타를 독출하는 제4단계: 및 상기 제4단계에서 독출한 사용자 정보 계층 2 프로토콜(UIL2) 데이타가 6, 7, 9, 10, 11, 14, 또는 1710이면 2번째 뒤의 옥텟인 제6b 옥텟의 비트7 내지 비트1을 읽어와 윈도우사이즈로서 출력하고, 사용자 정보 계층 2 프로토콜(UIL2) 데이타가 6, 7, 9, 10, 11, 14, 또는 1710이 아니면 0을 윈도우 사이즈로서 출력하는 제5단계를 구비한다.The present invention relates to a method for identifying a window size by finding a BLLI information element stored in the setup message by using a counter after storing a setup message received through a signal adaptation layer from an ATM network in a memory. Step 1: Obtaining the Length Information Ls of the Setup Message: Obtaining the BLLI Information Element Compared with 9510 While Incrementing the Count Value of the Counter; The third step: reading user information layer 2 protocol (UIL2) data from the BLLI information element; and the user information layer 2 protocol (UIL2) data read in the fourth step is 6, 7, 9 10, 11, 14, or 1710 reads bit 7 through bit 1 of the 6b octet, the second octet, and outputs it as the window size, and the user information layer 2 protocol (UIL2) And if the data is not 6, 7, 9, 10, 11, 14, or 1710, a fifth step of outputting 0 as the window size.
