A mechanism to control cooperative actions in multi-agent systems for network management systems that consists of agents managed by different network management authorities (NMAs), such as ISPs and universities, is presented. In spite of cooperative work among NMAs being indispensable for Internet management, NMAs do not always trust or coordinate with each(More)
Verifying whether the routing information originating from an AS is being correctly distributed throughout the Internet is important for stable inter-AS routing operation. However, the global behavior of routing information is difficult to understand because it changes spatially and temporally. Thus, rapid detection of inter-AS routing failures and(More)
Many studies have focused on developing Transmission Control Protocol (TCP) flow control mechanisms to enable more effective use of bandwidth in data center networks. However, the studies cannot achieve total optimization of bandwidth use for data center networks. This is because they do not take into account the path design of TCP flows and the(More)
Two sibling cases of facioscapulohumeral dystrophy (FSHD) are described. One was characterized by sensorineural hearing loss, marked tortuosity of retinal arterioles, an early onset and progression of severe restrictive-type pulmonary dysfunction, and cor pulmonale. The other had a mild course of FSHD without involvement of any other organ than muscles at(More)
To manage the changing conditions of the Internet and diagnose the cause of anomalies within it, network operators must obtain and analyze information from network devices such as routers and network monitoring tools. Of that information, route information exchanged by Border Gateway Protocol (BGP) is essential for understanding the Internet at an(More)
The Internet consists of several thousand interconnected autonomous systems (ASes). For enabling the autonomous network management that ensures stable access at the inter-AS level and flexible inter-domain routing control, it is important to know how the routing information originated from an AS spreads throughout the Internet and to control inter-AS(More)
A 14-year-old boy with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) is reported. He had suffered blepharoptosis and cataracts prior to the stroke-like episodes, and was thus reported in 1984 as having Kearns-Shy (Sayre) syndrome. After his death, an A-to-G mutation of the mitochondrial DNA (mtDNA) at bp 3243 was(More)
