ATM 스위치의 폭주 제어 및 최대 링크 이용률을 위한 대역 할당 알고리즘

정경택 한국통신학회 2000 韓國通信學會論文誌 Vol.25 No.11

ATM 스위치에서 입력 트래픽의 링크 이용의 불확실성과 입력 트래픽에 대한 예측 오류 등으로 인한 폭주가 발생될 가능성을 완전히 배제할 수 없기 때문에 스위치내부에서 폭주 발생을 억제할 수 있는 방법이모새되어야 한다.본 논문에서는 스위치 내부 링크의 대역 사용량을 측정하여 폭주 및 트래픽 제어를 수행하고 링크 이용률을 최대화하기 위한대역 할당 알고리즘을 제안한다. 폭주가 발생한 링크에 대하여 짧은 시간 내에 폭주를 해결하고 폭주가 발생하지 않은 링크에서는 사용하고 남은 여분의 대역을 공평하게 할당함으로서 링크의 이용률을 극대화할 수 있으므로 트래픽 관리를 보다 쉽고 효율적으로 수행할 수 있다.

Этноязыковая ситуация в Горно-Бадахшанской Автономной Области Республики Таджикистан

정경택 한국슬라브어학회 2021 슬라브어연구 Vol.26 No.1

In this paper I researched the language situation of the Gorno-Badakhshan Autonomous Oblast’ of Tajikistan. In the Gorno-Badakhshan Autonomous Oblast’ the status of Pamiris is now very low, and even they are ignored. And their languages are serving as a colloquial language in everyday life. Until the 1920s, Pamir languages are regarded as a different languages, but in 1926 it fell to dialects of Tajik language. In post-Soviet Tajikistan, Pamir languages are still a minority languages. Although the Language law adopted by Tajikistan in 1989 created conditions for the preservation, use and development of Pamir languages of the Gorno-Badakhshan Autonomous Oblast’, there is still ostensible preservation, use and development, and described their function problems as autonomous areas of the Gorno-Badakhshan Autonomous Oblast’, the status of these languages is still low. The issue of ethnic minority language was completely excluded from everyday life during the Tajikistan civil war, and as political centralization accelerated after the civil war, there is no meaningful policy for Gorno-Badakhshan at present. The declarative status of Gorno-Badakhshan's need to support and develop ethnic minority languages is only ostensible and does not exist.

This article aims to examine the possibility of conflicts and disputes between titular nations and ethnic minority groups in the post Soviet countries where most of the policies were designed only for the titular nations. Most of the Post-Soviet countries supported a policy that a language of the indigenous national must be used as a lingua franca. This caused the resistance of minority people in the countries. Especially, the promotion of the language status and function as an indigenous national language resulted in discrimination in the political, economic and socio-cultural areas of the ethnic minorities. In the 14 new independent countries except for the Russian Federation, the Russians became an ethnic minority. It led Russian peoples to emigrate out of the new independent country, creating a chaotic situation. In the Baltic region, Russians have descended to ethnic minorities, and the use of Russian language has also been banned. Thus there is a possibility of a conflict between the titular nations and Russians. The ethnic minorities in Moldova are also Russians, who constitute a de facto independent state, Transnistria. Another ethnic minority, the Gagauzes, compromised with the Moldovan government and formed a self-governing organization in the territory of Moldova. However, there is a possibility of a conflict between the titular nations and Gagauzes. Ethnic minorities in the Caucasus region are the Abkhazians, Ossetians of Georgia, the Russians and Azerbaijani of Armenia, and the Russians and Armenians of Azerbaijan. The status of the Russians and Russian language in Armenia and Azerbaijan remains virtually unchanged, but the Russian-speaking regions of Abkhazia and South Ossetia in Georgia are still likely to experience ethnic and language disputes. Minorities in Central Asia are the Karakalpaks and Tajiks in Uzbekistan, and the Uzbeks in Kyrgyzstan (mostly in Osh Province) as well as the Russians and Koreans, who were Russian single language users and became ethnic minorities in the new environment.

We approximately analyze the performance of the MIN's for interconnecting N processors or N processors to N commonly shared memory modules in a multiprocessor system. The performance of the MIN's with respect to their memory bandwidth is approximately analyzed and is compared to that of a crossbar under the hierachical model. It shown that for a higher rate of favorite requests the delta networks perform close to a crossbar.

러시아의 크림 병합과 벨라루스의 언어상황 연구

정경택 한국슬라브어학회 2019 슬라브어연구 Vol.24 No.2

The Republic of Belarus is the only post-Soviet country that has chosen Russian as its state language even after independence in 1991. In addition, since the inauguration of President Lukashenka in 1994, it was the most Russianized country to promote national integration with the Russian Federation. As a result, the Belarusians did not seek their own ethnic identity, and the Russia acknowledged that Belarusian language is a dialect of Russian. However, with Putin's emergence, the annexation of Crimea led the Belarusian government, especially President Lukašenka, to push for a de-Russianization policy, advocating the ideology of a single Russian nation, the Russian-led unification of the East Slavic people, and expanding its influence on Belarus, Crimea and eastern Ukraine, based on the economic development of Russia, political and social sector stability of Russia. The restoration of influence during the Soviet period of Russia, the preservation of identity in the local residence of overseas diaspora, the opposition to territorial search, and the flexible Belarusification by the ambition of President Lukašenka's individual began to be seen little by little since 2010 and the reality was revealed in earnest before and after the Russian annexation of Crimea in March 2014. This is the most obvious gradual exclusion of Russian, the most basic language in the social public sector, education system, and the media, which is causing a lot of confusion because it seems that legal and concrete enforcement methods are not prepared and improvised. Also, it is likely to be subject to economic sanctions and concerns of the Russian Federation, which is the most influential neighboring country, which is under the criticism, neglect, and criticism of the Russians, including the Russians in Belarus, or the majority of Belarusians. Belarus is an inland country bordering Latvia, Lithuania, Poland, Ukraine and Russia, and has always been influenced and influenced by neighboring powers from ancient times to the present. After independence in 1991, it promoted national integration as the closest country to Russia, and the change of language policy of the use of Belarusian in the recognition and expansion of the use of Russian language and the exclusion of Russian language at the same time was mainly influenced by President Lukašenka's own personal remorse. The revival of Belarusian national identity and the expansion of the use area of Belarusian as a Korean language in the Republic of Belarus and the restoration of its function and status as a first language should be based on the search and recognition of Belarusian national identity, establishment of writings, and changes in perception of More of Belarusian people, but it is clear that the influence of Russia, Russians and Russian will continue due to geopolitical situation. .

ATM ABR의 공평성들을 위한 새로운 스케쥴링 알고리즘

정경택,박준성,박현,전병실,Chung, Kyung-Taek,Park, Jun-Seong,Park, Hyun,Chon, Byoung-Sil 대한전자공학회 2002 電子工學會論文誌-TC (Telecommunications) Vol.39 No.4

The WRR scheduling algorithm is widely used in ATM networks due to its simplicity and the low cost of hardware implementation. It guarantees minimum cell rate according to the weight of each queue. The fairness is a important factor for ABR service. That is, scheduling algorithm allocates network resources fairly to each VC. However, WRR algorithm shows worse performance on bursty traffic. Because it schedules input traffics according to predetermined weight, it can not satisfies fairness criteria, MCR plus equal share and Maximum of MCR or Max-Min share, defined by ATM Forum TM 4.1 specification. The Nabeshima et al algorithm is not adapt to network status rapidly because it is not compensate the weights of unused bandwidth to VCs and assign the unused bandwidth to VCs by RR method. In this paper, we propose a scheduling algorithm for satisfying the two fairness criteria, MCR plus equal share and Maximum of MCR or Max-Min share, among the six criteria defined by ATM Forum TM 4.1 specification. The WRR, Nabeshima et al, and the proposed scheduling algorithms are compared with respect to fairness and convergence time throughout experimental simulation. According to the simulation results, the proposed algorithm shows higher fairness and more rapid convergence than other algorithms. WRR 스케줄링 알고리즘은 계산의 단순성과 저 비용 구현의 장점을 가지고 있어서 고속 패킷 스위칭 네트워크에서 널리 쓰이고 있지만 버스티한 트래픽에 대해서는 입력 트래픽을 일정 비율로 스케쥴링하기 때문에 효율성이 낮다는 문제점이 있다. 또한, WRR 알고리즘은 ABR 서비스 클래스의 공정성 기준인 MCR plus equal share와 Maximum of MCR or Max-Min share 공평성을 만족시키지 못한다. 또한 Nabeshima et al의 기법은 여분 대역에 대한 weight 값을 보정하지 않고 RR 방식으로 각 VC에 할당을 해주기 때문에 네트워크의 변화에 신속하게 적응하지 못할 뿐 만 아니라 대역폭을 효율적으로 이용하지 못한다. 따라서 ABR 서비스를 위한 공평성 기준을 만족시키고 빠르게 적응할 수 있는 스케줄링 알고리즘이 필요하다. 본 논문에서는 ABR 서비스를 위한 6가지 공평성 기준들 중 MCR plus equal share와 Maximum of MCR or Max-Min share 두 기준을 만족시키는 스케줄링 알고리즘을 제안한다. 제안된 알고리즘이 공평성 기준을 만족시키고, 네트워크 자원을 각 ABR VC들에게 신속하고 공평하게 할당해 주는지를 컴퓨터 시뮬레이션을 통하여 WRR, Nabeshima et al 알고리즘들과 비교, 분석한다.

THE RELATIONSHIP BETWEEN SHORT-RANGE MOVES AND LONG-RANGE MOVES

정경택,정동호 동양대학교 산업기술연구소 2001 東洋大學校 産業技術硏究所 論文集 Vol.3 No.1

We study the relationship between short-range moves and long-range moves by considering the first bifurcation point of r as a function of m in the game of life type automata network which is the two-dimensional probabilistic automata network model whose rule consists of two subrules. The first subrule, applied synchronously, is a local transition rule of nonzero sites characterized by the interaction with a neighborhood. The second one, applied sequentially, describes the motion of nonzero sites. The second subrule has been used to model complex systems when the movement of nonzero sites plays an important role. A new parameter r is introduced to represent the rare of long-range moves. When r is equal to zero or one, the motion of the nonzero sites is, respectively, purely short-range or purely long-range. In the game of life type automata network, as r increases, the stationary density of nonzero sites follows a route to chaos through the familiar cascade of period-doubling bifurcations. The first bifurcation point of r changes with m. Both limits of r, r → 0 and r → 1, gives the m for the purely short-range moves and the purely long-range move. The models of both range moves shows the same physical nature.
