Unicast-Based Multicast Communication in Wormhole-Routed Networks
TLDR
This paper presents efficient algorithms to implement multicast communication in wormhole-routed direct networks, in the absence of hardware multicast support, by exploiting the properties of the switching technology. Expand

Dynamic SDN controller assignment in data center networks: Stable matching with transfers
TLDR
We consider dynamic controller assignment as a stable matching problem with transfers, and propose a hierarchically two-phase algorithm that integrates key concepts from both matching theory and coalitional games. Expand

  • Mathematics, Computer Science
  • Int. J. Approx. Reason.
  • 1 February 1996
TLDR
In the existing evidential networks applicable to belief functions, the relations among the variables are always represented by joint belief functions on the product space of the variables involved. Expand

Carbon-Aware Load Balancing for Geo-distributed Cloud Services
TLDR
We propose a carbon-aware online control framework, which makes online decisions on geographical load balancing, capacity right-sizing, and server speed scaling. Expand

  • Artif. Intell.
  • 1 March 1995
TLDR
This paper presents a method for computing the marginal for a subset which may not be contained in one vertex of the Markov tree, but is a subset of the union of several vertices. Expand

Moderated Online Communities and Quality of User-Generated Content
TLDR
We show that when being moderated with different probabilities based on their reputations, commentators might display a pattern of reputation oscillation, in which they generate useful content to build up high reputation and then exploit their reputation. Expand
