Abstract: Provided is a congestion control method for controlling message flooding between nodes in response to situation information in information centric network environment with delay tolerant networking, and a recording medium and a device for performing the same. The congestion control method includes, when a first node contacts a second node, exchanging information associated with stored messages with the second node, identifying whether an anti-flag is stored in the first node, the anti-flag being assigned when each message arrives at a destination node, flooding of a non-anti-flagged message among the messages stored in the first node to the second node, and flooding of an anti-flagged message among the messages stored in the first node to the second node according to at least one of situation information including a hop count, a Time-To-Live (TTL) and a number of requester nodes of the corresponding message and a mobility of the first node, or restricting the flooding to the second node.

Abstract: A method for scheduling a virtual machine monitor having a scheduler, a task characteristic evaluation unit, and a credit management unit is provided. The virtual machine monitor drives at least two domains. The method includes scheduling, by the scheduler, the at least two domains, if an I/O event of each of the at least two domains in which the scheduling is performed is delayed, evaluating, by the task characteristic evaluation unit, a characteristic of a task of the at least two domains based on at least one of a central processing unit (CPU) intensive degree and an input/output (I/O) intensive degree of the at least two domains, differentially determining, by the credit management unit, an amount of credit in which each of the at least two domains retains according to the characteristic of the task, and determining, by the scheduler, an application frequency of a boost mechanism applied to the at least two domains according to the amount of credit.
