Abstract: Embodiments of present disclosure relate to a method and an electronic device for determining a storage node (SN) for a network element (NE) in a communication network. The method comprises detecting addition of a NE to a plurality of NEs, wherein each of the plurality of NEs is dynamically allocated to a virtualization unit of a plurality of virtualization units, obtaining context information associated with each of a plurality of storage nodes and the NE upon detecting the addition of the NE to the plurality of NEs, wherein the plurality of storage nodes is located in the communication network and configured to store data associated with the plurality of NEs, and determining a storage node from the plurality of storage nodes for the NE, based on the context information associated with each of the plurality of storage nodes and the NE, wherein the virtualization unit of the plurality of virtualization units allocated to each of the plurality of NEs is updated upon selection of the storage node for the NE.

Abstract: A Method and a system for securing a SDN controller from denial of service attack are provided. A SDN controller receives, from a networking device, data packets pertaining to a flow in Packet_IN messages, if the flow does not match flow entries in a first flow table of the networking device. A table miss flow entry pertaining to the flow is created in a second flow table of the networking device for sending the Packet_IN. The SDN controller installs a flood prevention flow entry in the second flow table to enable the networking device to drop subsequent data packets pertaining to the flow until the SDN controller installs, in the first flow table, a flow entry matching the flow. The flood prevention flow entry is deleted from the second flow table after the installation of the flow entry matching the flow.

Abstract: Embodiments herein provide a method for managing a network slice load in a wireless network. The method includes: sending, by a CN device, a request message for network slice load information to a base station of the wireless network; determining, by the base station, the network slice load based on the parameter; sending, by the base station, the response message comprising the network slice load information to the core network device for managing the network slice load; determining, by a CN device, the network slice load at the base station based on the response message; and managing, by a CN device, the network slice load at the base station.

Abstract: A method for controlling a User Equipment (UE) policy by a UE is provided. A method includes receiving the UE policy from a Policy Control Function (PCF), performing a first action in response to receiving the UE policy from a successful execution of the received UE policy, a failed execution of the received UE policy, and storing of the received UE policy, and transmitting a feedback message to the PCF based on the first action.

Abstract: The present disclosure relates to method and system for user equipment (UE)-initiated network slice registration and traffic forwarding in telecommunication networks. In an embodiment, for network slice registration, UE transmits a registration request to an AMF via a base station of telecommunication network. In response to the registration request, the AMF transmits a registration accept response comprising network slice selection assistance information (NSSAI) to the UE. For traffic forwarding, the UE transmits a PDU session establishment request comprising single NSSAI to the telecommunication network. The base station of the telecommunication network maps the single NSSAI to a Flow Label field of IPv6 header and transmits to DPAF via specific SLF of the telecommunication network.
