Fault Management in Crossbar ATM Switches

오민석,Oh Minseok Korea Information Processing Society 2005 정보처리학회논문지 C : 정보통신,정보보안 Vol.11 No.1

다중채널 스위치는 ATM (Asynchronous Transfer Mode)로 널리 사용되는 스위치 구조이며, 스위치의 내부에 장애에 대한 내성(tolerance) 을 구현할 수 있는 것으로 알려져 있다. 예를 들어, 하나의 다중 채널 그룹에 속하는 링크에 장애가 있을 경우, 장애 링크로 통과하려는 트래픽을 여분의 링크가 책임을 질 수 있게 할 수 있다. 스위치 소자에 발생하는 장애는 ATM 셀을 잘못 라우팅하거나 출력단에 도달하는 셀의 순서를 뒤바꾸게 할 수 있다. 본 논문에서는 다중 채널 크로스바 ATM 스위치에 적용할 수 있는 두 가지의 장애 위치 확인 알고리즘을 제안한다. 첫 번째로 제안하는 최적 알고리즘은 시간적으로 최상의 성능을 보여주지만, 계산상으로는 복잡하게 되어 결과적으로 실제 구현이 어려울 수 있다. 이러한 문제점을 해결하기 위해 최적의 알고리즘보다는 계산상으로 보다 효율적인 온라인 알고리즘을 제안한다. 두 알고리즘의 성능은 시뮬레이션을 통해 검증한다. 온라인 알고리즘은 랜덤 트래픽 및 버스티(bursty) 트래픽에 대해 거의 최적에 가까운 성능을 보여 준다. 한편, 제안된 알고리즘으로 장애론 찾아낼 수 없는 경우가 있는데, 그에 대한 열거 및 원인을 제시한다. 끝으로 장애 위치 확인 알고리즘을 이용해서 찾은 장애를 우회하기 위해 행과 연을 추가하는 장애 복구 알고리즘을 제안하다. The multichannel switch is an architecture widely used for ATM (Asynchronous Transfer Mode). It is known that the fault tolerant characteristic can be incorporated into the multichannel crossbar switching fabric. For example, if a link belonging to a multichannel group fails, the remaining links can assume responsibility for some of the traffic on the failed link. On the other hand, if a fault occurs in a switching element, it can lead to erroneous routing and sequencing in the multichannel switch. We investigate several fault localization algorithm in multichannel crossbar ATM switches with a view to early fault recovery. The optimal algorithm gives the best performance in terms of time to localization but it is computationally complex which makes it difficult to implement. We develop an on-line algorithm which is computationally more efficient than the optimal one. We evaluate its performance through simulation. The simulation results show that the Performance of the on-line algorithm is only slightly sub-optimal for both random and bursty traffic. There are cases where the proposed on-line algorithm cannot pinpoint down to a single fault. We enumerate those cases and investigate the causes. Finally, a fault recovery algorithm is described which utilizes the information provided by the fault localization algorithm The fault recovery algorithm providesadditionalrowsandcolumnstoallowcellstodetourthefaultyelement.

본 논문에서는 LTCC(Low Temperature Co-fired Ceramic) 공정을 이용한 K/Ka 대역(20~21 GHz/30~31 GHz) 위성통신 송수신 겸용 L형태의 광대역 원형편파 안테나를 제안하였다. 이 안테나는 상대 유전율이 5.2인 LTCC 공정을 이용하여 제작되었으며 적층형 구조로서 다른 RF 회로와 집적화가 가능하다. 또한 LTCC을 이용하였으므로 가벼우면서 다른 RF 회로와의 집적화를 통해 손실을 줄일 수 있고, 전체적으로 시스템 크기를 줄일 수 있다. 본 논문에서 사용한 안테나는 모노폴 안테나의 구부러진 L형태의 간단한 구조로서 LTCC 공정상에서의 구현을 쉽게 하고 손실을 최소화할 수 있도록 하였다. The TX/RX broadband L-type circular polarization antenna using LTCC(Low Temperature Co-fired Ceramic) for satellite communication at K, Ka band(20~21 GHz/30~31 GHz) has been presented. This antenna has been analyzed in compensation for LTCC with relative permittivity 5.2 and could have been integrated with RF component. Also antennas on LTCC enable :o reduce loss of RF system due to integrate with RF circuits and to light weight, and thus, generally one can reduce size of the RF system. As the geometry of this antenna presented is made simple by L type of monopole antenna, it is easily manufactured by LTCC progress and enables to reduce loss.

효율적인 휴리스틱 계산 처리를 위한 가중치 기반의 선수행 A^* 알고리즘

오민석,박성준,Oh, Min-Seok,Park, Sung-Jun 한국게임학회 2013 한국게임학회 논문지 Vol.13 No.6

경로 탐색은 인공지능의 매우 중요한 요소 중의 하나이며, 여러 분야에서 두루 쓰이는 과정이다. 경로 탐색은 매우 많은 연산이 필요하기 때문에 성능에 매우 중대한 영향을 미친다. 이를 해결하기 위해서 연산량을 줄이는 방식의 연구가 많이 진행되었고, 대표적으로 A* 알고리즘이 있으나 불필요한 연산이 있어 효율성이 떨어진다. 본 논문에서는 A* 알고리즘 중 연산 비용이 높은 노드 탐색 수 등 연산량을 줄이기 위해서 가중치 기반의 선수행 A* 알고리즘을 새롭게 제안한다. 제안한 알고리즘의 효율성을 측정하기 위해 시뮬레이션을 구현하였으며, 실험 결과 가중치를 이용하는 방법이 일반적인 방법보다 약 1~2배 높은 효율을 보였다. Path finder is one of the very important algorithm of artificial intelligence and is a process generally used in many game fields. Path finder requires many calculation, so it exerts enormous influences on performances. To solve this, many researches on the ways to reduce the amount of calculate operations have been made, and the typical example is A* algorithm but it has unnecessary computing process, reducing efficiency. In this paper, to reduce the amount of calculate operations such as node search with costly arithmetic operations, we proposes the weight based pre-processing A* algorithm. The simulation was materialized to measure the efficiency of the weight based pre-process A* algorithm, and the results of the experiments showed that the weight based method was approximately 1~2 times more efficient than the general methods.

모순어(矛盾語)의 형태(形態)와 의미(意味)

오민석(吳玟錫) ( Oh Min-seok ) 한국어문교육연구회 2020 어문연구(語文硏究) Vol.48 No.1

모순어는 하나의 언어 단위가 공시적으로 의미 대립성을 보이는 다의어다. 이 글에서는 모순어를 판정할 때 고려할 사항들을 형태와 의미를 중심으로 살펴보고 정리해 보았다. 우선 선행연구들의 목록을 정리하고 이 가운데 이질적인 항목을 추리는 과정을 통해 목록의 균질성을 도모했다. 모순어라는 언어 단위는 내부를 분석할 수 없음을 ‘전부-전무’, ‘밤낮’, ‘길흉’ 등을 통해 확인했다. 그리고 모순어의 판정은 형태가 아닌 의미에 집중해야 함도 ‘우연찮다’, ‘어쭙잖다’ 등을 통해 확인했다. ‘-잖/찮-’의 형태가 모순어의 의미 대립성을 파악하는 데 혼란을 줄 수 있기 때문이다. 한편 모순어를 판정할 때 모순어의 형성 기제를 생각해 보지 않을 수 없다. 이를 위해 부정서술어와의 공기어가 보이는 의미 변화를 통해 의미의 전염 양상을 살펴보고 ‘빌리다’ 류 어휘들을 통해 동시성을 살펴보았다. 마지막으로 담화 차원에서 단발성 모순어의 존재를 ‘죽다’, ‘죽이다’, ‘잘하다’ 등을 통해서 확인했는데 한국어 모순어를 입체적으로 이해하기 위해서는 이들을 보다 잘 이해할 필요가 있다. In this paper, we have looked at the grammatical characteristics that would be considered in defining what Korean contronymy is, internal-contrariness in a single linguistic unit, word, phrase, sentence. Looking at the list of preceding studies, we reconfirmed that contronymy is polysemy and through “jeon-bu(full)-jeon-mu(nothing)” and “bamnat(night-day)”, “gilhyug(good-ill luck)” the contronymy should not be internally analyzed for a single linguistic unit. It also confirmed that in order to define contronymy, each-opposite meanings in a single linguistic unit should be looked at through “uyeon-chanh-da (being accidental)” and “eojjup-janh-da (clumsy)”, and that the contradiction should be checked not in the form as ‘-잖/찮’ but in the meaning of words. We looked at the contagion from negative predicate and concurrency with “billida(rent)”-type words as the basis for the formation of controymy. By confirming the existence of one-time contradictory words at the discourse level, such as “jugda(die)”, “jugida(kill)” and “jal-hada(do well)” which were not paid attention in preceding studies, we will be able to understand the Korean contronymy in full.

내적 식민지와 텍스트의 정치학: 암스트롱의 『슬래쉬』 읽기

오민석 ( Oh Min Seok ) 대한영어영문학회 2010 영어영문학연구 Vol.36 No.3

This paper suggests that the concepts, internal colony and textual politics, can illuminate the aboriginal literature more deeply and systematically. In this paper the internal colony means the phenomena and the space in which the colonizers who monopolize and the power keep on exploiting and repressing the colonized continuously in a nation by eternalizing its colonization. The term “textual politics” implies that the struggles between the colonizer and the colonized are practiced on the ground of text or discourse. Aboriginal writings have diverse strategies to disturb, subvert, and decenter the (European) colonial discourse. Slash, the first novel written by Canadian aboriginal writer Jeannette Armstrong, mobilizes the narrative of Bildungsroman and romance to show the real history of the aboriginal people hidden in the internal colony and the diverse spots of decolonization. Through the maturing process of the hero Slash, we can visit the vivid fields of the struggle of decolonization. The other representational strategy of the text is realism. Depending on the definitions of G. Lukács’ realism, this paper reads the textual politics of Slash and confirms that its achievement as a novel is based on its realist writing strategy.

내적 식민지, 판타지, 그리고 성의 정치학: 컬리턴의 『에이프릴 레인트리를 찾아서』

오민석 ( Min Seok Oh ) 영미문학연구회 2008 영미문학연구 Vol.14 No.-

This paper aims to read Beatrice Culleton`s In Search of April Raintree in terms of internal colony, fantasy, and sexual politics. This work is the first modern novel published by a Canadian aboriginal writer. To approach aboriginal writings focusing only on their common distinctive features such as affinity with nature, oral tradition, ritual, anti-materialism, etc. can be an effective way to introduce them but may alienate and separate them in a museum of literary history. The aboriginal life, culture, and literature have been involved in the contemporary capitalist society, in itself a part of it, and existing as the living present. Therefore the aboriginal literature should be treated as the present not as the past and as a kind of contemporary minority literature. Internal colony in this paper means the phenomena and the space in which the colonizer who monopolizes the capital and the power keeps on exploiting and repressing the colonized continuously in a nation, in a territory, and in a society by eternalizing its colonization. In Culleton`s novel, the internal colony is entangled with various fantasies of the colonizer and the colonized. These fantasies form the identities of both the colonizer and the colonizer, distorting their identities at the same time. April and Cheryl is the typical characters who show the case of the colonized in this internal colony. Internal colony is basically a political concept but cannot be understood in isolation from gender and sexual politics. Culleton`s novel shows this especially with its long and detailed scene of sexual rape and the concept of "native girl syndrome" which is the colonizer`s, etc. In conclusion, Culleton`s novel is the typical text which shows the contradictions of internal colony and for reference its discursive transparency matches well its content which is obliged to be discussed in an other paper.
