Abstract:
An operation method of a first device in a communication system supporting network slicing may comprise receiving a first message requesting capacity planning of a network slice from a second device; obtaining information required for the capacity planning; transmitting a second message including the required information to a third device supporting a function of the capacity planning; receiving a third message including a result of performing the capacity planning from the third device; and performing a reallocation operation or a modification operation of the network slice based on the result of performing the capacity planning
Abstract:
A content system and method in which content may be divided into chunks and distributed and stored in content routers or content servers, content routing information corresponding to information on the distributed and stored content may be provided to a client terminal when a request for the content is received from the client terminal, and the client terminal may receive the distributed and stored content in chunk units based on the received content routing information.
Abstract:
The present disclosure relates to a method and apparatus for control action based on software-defined networking associated with quantum key distribution network (QKDN) management in a quantum key distribution network. A method for performing a control action associated with QKDN management in a QKDN according to an embodiment of the present disclosure may include: receiving, by a first control entity, control action information from a QKDN manager; determining, by the first control entity, a target of the control action based on the control action information; classifying, by the first control entity, the control action sequentially as one of a routing or rerouting-related control action, a provisioning-related control action, a protection or recovery-related control action, and a charge-related control action based on the target of the control action; and transmitting, by the first control entity, information for performing the control action for a target associated with the classified control action.
Abstract:
A network slice interworking method includes receiving a network slice information request from a user equipment (UE), identifying network slice subscription information of the UE, verifying whether the network slice subscription information matches pre-stored network slice selection assistance information (NSSAI), transmitting network slice information including the pre-stored NSSAI to the UE when the network slice subscription information matches the pre-stored NSSAI, transmitting a network slice selection request to a network slice selection function (NSSF) when the network slice subscription information does not match the pre-stored NSSAI, receiving a network slice selection result in response to the network slice selection request, and transmitting network slice information including the received network slice selection result to the UE.
Abstract:
A method and an apparatus for configuring multi-paths that are made by means of MPTCP using a segment list which determine and configure a network path so as to minimize a difference in capability between paths in configuring the multi-paths.
Abstract:
Disclosed are an apparatus and method for inferring a service plan for seamlessly providing an IPTV service. The present invention proposes a context inference algorithm for performing multiple-criteria decision-making using Analytic Hierarchy Process (AHP) for context element evaluation through a context inference apparatus for providing a seamless IPTV service using a context awareness technology for recognizing device change and environmental change in a ubiquitous home networking environment including various types of information terminals.
Abstract:
A segment routing-based MPLS packet forwarding method and a device thereof are proposed. The method includes establishing a forwarding path in a Multiple Protocol Label Switching (MPLS) network by receiving a packet, checking whether processing of a size of a label stack related to each node included in the forwarding path is available or not in each node, generating a first MPLS packet by adding an MPLS header having the label stack to the packet in response to availability of the processing, and generating a second MPLS packet by adding an extension header having the label stack and by adding an MPLS header having a part of the label stack allocated according to the label stack size processable by each node to the packet in response to unavailability of the processing.
Abstract:
The present disclosure relates to a method and apparatus for key relay control based on software-defined networking in a quantum key distribution network. A method of controlling key relay in a quantum key distribution network (QKDN) according to an embodiment of the present disclosure includes: receiving, by a first control entity, a key relay route request from a key management (KM) layer; determining, by the first control entity, whether or not key relay is associated with a plurality of resource groups; and, transmitting a key relay route request from the first control entity to a second control entity, when key relay is associated with the plurality of resource groups, wherein key relay route information produced by the second control entity may be provided to the KM layer.
Abstract:
There are provided a method and an apparatus for transmitting an IP packet using segment routing. A path controller for transmitting an IP packet in a mobile communication system including heterogeneous networks includes a data transmission path establishing module configured to, if a request message for establishing a data path is received from any one of a plurality of mobile nodes, determine transport nodes that the IP packets is traverse between mobile nodes, and transmit segment values corresponding to the determined transport nodes to the mobile nodes sending the request message for establishing the data path, wherein the plurality of mobile nodes are connected to transport nodes and there may be a lot of data paths between them.
Abstract:
Disclosed are a method and a system for providing a context awareness based networking operation in smart ubiquitous networks. The present invention provides a network entity with a networking operation that enables dynamically acquiring context information from various sources (for example, an end user, an end user device, a network, a service, and a content) in smart ubiquitous networks, processing, that is, analyzing and deducing related information in the acquired context information, and thereafter, controlling and managing the network depending on the recognized context.
