Abstract:
In a content network over which a plurality of smart nodes is coupled, a content network management system receives information response messages including pieces of management interface base (MIB) information from smart nodes. Next, the content network management system classifies the pieces of MIB information included in the received response messages into server resource information, topology information, and network resource information, and stores and manages the pieces of information.
Abstract:
Disclosed is a network service system including a terminal selectively providing packets of an information centric networking (ICN) protocol and an Internet protocol, a smart digital unit (DU) identifying whether the packets provided from the terminal correspond to an ICN protocol packet or an Internet protocol packet to transfer the packets through different paths depending on a type of the identified packet, and an ICN node receiving the ICN protocol packet from the smart DU to provide contents.
Abstract:
Disclosed is a virtual file system for interworking between a content server and an information-centric network server, the system including: a file system function processing unit configured to process a file operation for a predetermined content requested from a plurality of content service protocols; a cache control unit configured to process the content requested through the file operation by managing a cache in a node; and a protocol matching unit configured to process the content requested through the file operation by interfacing with a plurality of content transfer protocols.
Abstract:
The present invention relates to a content providing system and method combining a transparent Internet cache (TIC) server and a content delivery network (CDN), and more particularly, to a content providing system and method that may overcome limitation on capacity of a cache storage found in a TIC service and may also overcome limitation on service transparency found in a CDN service. According to the present invention, it is possible to overcome limitation on capacity of a cache storage found in an existing TIC service and to overcome limitation on service transparency found in a CDN by combining a TIC server and the CDN.
Abstract:
An apparatus for integrally managing a route between terminals of a multi-network and a method of setting a route between terminals of a multi-network are provided. The integrated route management system apparatus includes: a network route management processor that manages a route that is included in an individual network of the multi-network; a route state and performance monitoring unit that collects information about a route state and route performance from a network node that is included in the route; and an integrated route management processor that sets a route between terminals of the multi-network based on a route that is included in the individual network.
Abstract:
Disclosed are an apparatus for configuring an overlay network and a method thereof. An apparatus for configuring an overlay network may include a network configuring device collecting topology information and bandwidth information of a physical network and configuring one logical network including a plurality of predetermined nodes by using the collected topology information and bandwidth information of the physical network; and a storage device storing the topology information and bandwidth information of the physical network.
Abstract:
A synchronization method performed by a first communication node may include: receiving, from a second communication node of the communication system, a first synchronization information signal including information on a first synchronization reference time and information on a first offset; identifying information on a first time at which the first synchronization information signal is transmitted and information on a target synchronization time configured by the second communication node, based on the information included in the first synchronization information signal; setting a synchronization timer based on the information on the first offset; and when the synchronization timer expires, determining that time synchronization with the second communication node is acquired.
Abstract:
In a content network over which a plurality of smart nodes is coupled, each smart node receives advertisement messages broadcasted by adjacent smart nodes. The advertisement message may be one of a link state advertisement (LSA) message including link state information indicative of a link that is a network interface, a server state advertisement (SSA) message including server state information indicative of a data storage state and a processing state of a processing unit of the smart node, and a content state advertisement (CSA) message including content state information indicative of content stored in the smart node. Each smart node updates its own database based on the information included in the received advertisement message.
Abstract:
In order to easily prevent traffic of a content data server, which provides an arbitrary content, from being overloaded, the content transmission system according to an exemplary embodiment includes a content data server which provides an arbitrary content to a plurality of terminals when a request signal for the arbitrary content is input from the plurality of terminals, a data control server which when the arbitrary content is provided, monitors whether the traffic of the content data server is overloaded and if the traffic is overloaded as a result of monitoring, generates a traffic distribution request signal, and a node control server which when the traffic distribution request signal is input from the data control server, controls to provide the arbitrary content to an arbitrary distribution node, which satisfies a setting standard among a plurality of distribution nodes, to be provided to an arbitrary terminal among the plurality of terminals.
