Design and deployment of secure, robust, and resilient SDN Controllers

The scale of the Software-Defined Network (SDN) Controller design problem has become apparent with the expansion of SDN deployments. Initial SDN deployments were small-scale, single controller environments for research and usecase testing. Today, enterprise deployments requiring multiple controllers are gathering momentum e.g. Google’s backbone network, Microsoft’s public cloud, and NTT’s edge gateway. Third-party applications are also becoming available e.g. HP SDN App Store. The increase in components and interfaces for the evolved SDN implementation increases the security challenges of the SDN controller design. In this work, the requirements of a secure, robust, and resilient SDN controller are identified, stateof-the-art open-source SDN controllers are analyzed with respect to the security of their design, and recommendations for security improvements are provided. This contribution highlights the gap between the potential security solutions for SDN controllers and the actual security level of current controller designs.

Multilateralism and the Multinational Enterprise

How do multilateral institutions influence the strategic choices and actions of international managers? This paper addresses the question by exploring the impact of the World Trade Organization's (WTO) decision-making process on multinational enterprises (MNEs). We discuss the three phases of the WTO decision-making lifecycle - the formulation of trade rules, the implementation of those rules, and the enforcement of the rules – and propose a strategic adjustment framework for understanding how companies alter their strategies and structures in response to the WTO's rules and operations. We argue that the increased relevance of multilateral rules and enforcement mechanisms – embodied in the WTO - is an important influence on MNE strategies and structures because of the increasing embeddedness of the WTO in national levels of regulation. We illustrate this through examples taken from the pharmaceutical, textiles and sugar industries sectors that have witnessed substantial multilateral regulation.

China's Enterprise Bankruptcy Law (EBL 2006): Cross-Border Perspectives

With China's new Enterprise Bankruptcy Law (‘EBL 2006’) having come into effect on 1 June 2007, a critical issue arises as to the extent to which Article 5, as a cross-border provision, will strengthen creditors' rights across jurisdictions. In this paper attention will be paid in particular to how the Chinese People's Court is likely to exercise its discretion to grant recognition to a foreign court ruling, and vice versa. The paper will start with a brief introduction to the circumstances under which Article 5 came into being. The evolution of China's cross-border insolvency practices will be examined through an analysis of an inbound case of B&T (2002) as well as an outbound one of GITIC (2005). In spite of the fact that China has not adopted the UNCITRAL Model Law, essential factors deemed necessary to be considered by China's court and its counterparts in US and UK are to be highlighted throughout the paper. Although the effect of Article 5 remains to be seen, it will be critically analysed focusing on some controversial issues.
