    Abstract: A system and method for processing network packets based on NFV for ensuring high availability are disclosed. The disclosed system may include: at least one server, where a multiple number of VNF's for performing particular service functions are formed in the at least one server, each of the VNF's including at least one VNF instance; and a control apparatus that sequentially selects an M number of VNF's and selects one VNF instance from each of the selected M number of VNF's to configure an SFC, where the control apparatus may calculate an availability cost ratio value associated with each of the at least one VNF instance within VNF i+1 with respect to a VNF instance selected from VNF i (i being an integer from 1 to M) and may select a VNF instance within the VNF i+1 corresponding to the maximum value among the availability cost ratio values.

    Abstract: A method of constructing and maintaining a circle-mesh overlay network is disclosed. The method of constructing a circle-mesh overlay network includes: (a) determining a reference member number of a circle overlay by using a total number of participating peers; (b) creating a new circle overlay and adding member peers from among the participating peers to the new circle overlay in consideration of the reference member number; and (c) forming a circle-mesh overlay network by way of interconnection between the new circle overlay and a different circle overlay.

    Abstract: Provided is a method for managing an address for an application of a LISP (Locator ID Separation Protocol) network system in a distributed container-based virtualization environment, and the method comprises detecting, by a service discovery agent of a container platform, generation of an application in a corresponding cluster; querying, by the service discovery agent, a service IP address to be assigned to an application to be generated by transmitting a service name to a central control plane; searching, by the control plane, for a service IP address matching the service name and transmitting the service IP address to the service discovery agent; and transmitting, by the service discovery agent, the service IP address to a manager of the container platform to complete the generation of the application, and mapping the service IP address to a public IP for the generated application to register it in the control plane.

    Abstract: The present disclosure provides a method for processing data by an edge node including: receiving a data request from an application; confirming whether first data corresponding to the data request is included in a content storage of the edge node; confirming whether there is second data having a correlation with the first data which is equal to or higher than a predetermined threshold value based on a previously stored mapping table when the first data is not included in the content storage of the edge node; and transmitting the second data to the application when there is the second data having the correlation with the first data which is equal to or higher than the threshold value.

    Abstract: A method and system for providing flow mobility in a distributed mobility management network are disclosed. The method of controlling data flow mobility can include: (a) receiving session information in correspondence to a connection to each mobile access router from said mobile access router and storing the session information, which may include terminal information, an allotted address, and data flow information; (b) determining a target data flow to be moved by analyzing the session information according to a flow movement policy; and (c) transmitting a flow movement request, which includes the allotted address corresponding to the determined target data flow, to a new mobile access router.

    Abstract: Provided are a mobile evolve packet core (EPC) and a paging method using the same. The mobile EPC includes: a mobile EPC server providing an environment for operating a set of virtual machines (VMs), each of the virtual machines serving as a functional entity of a core network of a mobile communication system; a transmission module transmitting/receiving between the mobile EPC server and components of the mobile communication system or between the mobile EPC server and another mobile EPC server; and a mobile means with the mobile EPC server and the transmission module and providing mobility, wherein the mobile EPC moves to a disaster area to form a public safety network (PSN).
