面向大规模容器集群的网络控制技术

针对容器技术在网络层面缺乏控制的问题,设计一套面向大规模容器集群的网络控制架构,分别从容器集群网络的灵活组网、智能适配以及安全隔离三个方向进行研究,主要解决大规模容器集群部署中的网络适配和隔离控制等关键问题。实验结果表明,设计的网络控制架构可以根据网络特点有针对性地实现虚拟局域网的快速划分、网络节点的稳定迁移和节点通信的精确隔离控制。     

Local perceptions of the EU’s role in peacebuilding: The case of security sector reform in Palestine

ABSTRACT

Perception research can make a valuable contribution to the study of the local dimension in EU peacebuilding. The conceptual framework developed in this article distinguishes between perceptions of the “legitimacy,” “effectiveness,” and “credibility” of EU peacebuilding practices, which are crucial factors for successful peacebuilding. Relying on the case of the EU’s support for security sector reform (SSR) in Palestine, this article shows that local stakeholders—which participate in various EU-sponsored training and capacity-building programs—display considerable support for liberal peacebuilding norms. Yet, perceived discrepancies between the EU’s peacebuilding rhetoric and its SSR activities have severely undermined the potential of the EU’s liberal peacebuilding model in the eyes of Palestinian stakeholders. Critical local perceptions are frequently articulated with reference to the EU’s own liberal peacebuilding discourse, pointing to a lack of inclusiveness of the SSR process and deficits in terms of democratic governance and the rule of law.     

Security,structural factors and sovereignty: Analysing reactions to Kenya’s decision to close the Dadaab refugee camp complex

Kenya’s decision to close the Dadaab refugee camp complex highlights structural flaws in the international refugee regime. While much attention has been paid to Kenya’s reasoning, less has been given to the reactions of organisations and states. Given the state’s primacy in the international system and uncertainty about refugees, Kenya’s decision is perhaps unsurprising. It is contended that the stakeholders were unprepared because of path dependence and disbelief that Kenya would repatriate the refugees. While stakeholder reactions arguably demonstrate concern for refugees, the international refugee regime remains unquestioned, sustaining revenue streams that may fuel corruption, encourage lengthy encampment and prolong conflict.     

Safety in international security: a view point from the practice of accident investigation

While security points to a deliberate harming of humans and/or the environment, safety refers to unintended damage. In this view point, I will analyse how the distinction between safety and security matters in the practice of accident investigation and I will argue that the division between the fields is problematic for the assessment of security-related safety risks. Drawing on the case of the our accident investigation into the downing of flight MH17 above Ukraine in 2014, I highlight key dilemmas the Dutch Safety Board dealt with.

军队政治工作信息资源元数据标准

随着政治工作信息资源管理的需要,运用元数据来描述政治工作信息资源正逐渐成为普遍趋势,由于政治工作信息资源来源广泛种类复杂,如果缺乏顶层设计,势必会造成元数据标准不统一不规范的现象,从而影响政治工作信息资源管理。文章研究军队政治工作信息资源元数据标准的内涵,阐述其在政治工作信息化建设中的作用价值,提出具体设计应该遵循的原则和步骤。     

A Dangerous Method: How Mali Lost Control of the North,and Learned to Stop Worrying

Abstract

This article analyses changes and failures in the northern Mali system of security governance, taking into account the period running from the declaration of the Malian Third Republic (1992) to the present. Considering northern Mali as an area of limited statehood, the article develops a comparative diachronic analysis, distinguishing between three phases, namely Militiarisation (1992–2002), Fragmentation (2002–2012) and Multiplication (2013–ongoing). For every phase the focus is on (1) the mechanisms of coordination among actors, (2) the distribution of coercive capacities and ruling power and (3) the forms of authority. Unintended consequences and collective problems are highlighted, in order to understand the current situation of insecurity in the area.     

Recognizing Fragmented Authority: Towards a post-Westphalian Security Order in Iraq

Abstract

The rollback of Daesh’s territorial control during 2017 has (re-)established an area of limited statehood in large parts of Iraq that may endure for many years. The government of Iraq projects its authority into a large geographical and political space that it shares with a multitude of other state, non-state and hybrid actors, competing and collaborating to achieve advantageous security and political outcomes. This paper examines the heterarchy of actors in post-Daesh Iraq to develop a typology and start a critical discussion about post-Westphalian alternatives for security governance in Iraq during the coming period of reconstruction and reconciliation.     

Hizbullah’s Shaping Lebanon Statehood

Abstract

Since the end of the civil war in 1990, the Lebanese second Republic has experienced a dual security governance in the southern borderland region. Up to the Syrian military withdrawal in 2005, the territorial and functional ‘areas of limited statehood’ between the State and Hizbullah worked as a cooperation. After the Syrian withdrawal, various forms of cooperation appeared, raising the theoretical interest for the ‘mediated state’ framework. It is conceptualizing the cooperation between the state and the non-state actor as an interdependency – with case study ranging from the marking of the Blue Line to the struggle against the jihadists groups.     

Security gradient and national defense – the optimal choice between a draft army and a professional army

The earlier work on the optimal design of the national security has focused on the opportunity cost of the draft in terms of foregone human capital formation. The current paper introduces the national security into the welfare analysis missing from the earlier work. This creates a trade-off between the private goods and the security as a public good in the social cost–benefit analysis. There are three major results. First, and arising from the intergenerational interaction, it is optimal to introduce a pay to the young generation when in duty even by resorting to a distortive tax. Second, when optimizing the size of the army, the optimal choice between the draft army and the professional army depends on the risk class of the country. A security gradient arises. Third, the choice is linked to the size and the quality of the reserve generated by the two approaches.
