Provided are a method and apparatus for processing a router advertisement message, a storage medium, and an electronic apparatus. The method includes acquiring, on a current node, a border gateway protocol (BGP) router advertisement message transmitted by a previous node, the BGP router advertisement message indicates a BGP next-hop node in a forwarding direction, and the forwarding direction is a direction from the network ingress node to the network egress node; and determining, in a case that the BGP next-hop node and the current node are two adjacent nodes on the propagation path, an underlying transport path from the current node to the BGP next-hop node according to instruction information corresponding to the current node of the information of the propagation path. According to examples of the disclosure, the technical problem that an underlying transport path cannot be flexibly determined in the related art is solved.

The present disclosure refers to methods and systems to reduce delays in VoWI-FI handover and packet switching registration. The method includes triggering a Router Solicitation Router Advertisement (RSRA) procedure to establish a Transmission Control Protocol / Internet Protocol (TCP / IP) interface based on a determination that the VoWi-Fi handover of a user equipment (UE) is to be performed, determining if a router advertisement (RA) is received within a first time interval, and obtaining a full Internet Protocol version 6 (IPv6) address previously used by the UE in response to determining that the RA is not received within the first time interval, the full IPv6 address being for establishing the TCP / IP interface with a network.

The embodiment of the invention provides an intelligent router and an address allocation method, and the method can respond to a change event of network configuration, search an initial notification message generated based on superior equipment, and generate a target notification message according to the initial notification message. Wherein the initial notification message is a sent router notification message, the key information field of the target notification message is the same as the key information field of the initial notification message, and the life cycle of the target notification message is smaller than the life cycle of the initial notification message. And the target notification message is sent to the subordinate equipment, so that the subordinate equipment sends a request message according to the life cycle of the target notification message and requests the router notification message again. According to the method, when the change event of the network configuration is detected, the subordinate equipment is notified to re-request the router notification message through the target notification message, so that the subordinate equipment can update the IP address in time according to the router notification message, and the accuracy of the IP address is ensured.

The invention relates to the technical field of computer networks, in particular to an ONU gateway IPv6 address allocation method and device of a PON network, equipment and a medium. In addition, the ONU problem solution obtaining method of the PON network can also be applied to a fiber to room (FTTR), an enterprise-level fiber to room (FTTR-B) and a broadband fusion terminal product, and the ONU problem solution obtaining method of the PON network can also be applied to the FTTR, the enterprise-level FTTR-B and the broadband fusion terminal product. The ONU gateway obtains an association mapping table, and records a multi-WAN link PD prefix and a binding relationship between the multi-WAN link PD prefix and an LAN bridging group comprising at least one LAN port; expanding a router announcement function based on the table, and directionally distributing an announcement message containing a matched PD prefix to an LAN port access terminal; and meanwhile, a DHCPv6 function is expanded, a terminal request message is received, an interface identifier is extracted, a PD prefix is matched in combination with the corresponding relationship between the bridging group and the port, and the two are combined to generate a complete IPv6 address and returned through a response message. According to the invention, the problem that the LAN port and the IPv6 address under the multi-WAN link cannot be accurately bound and allocated in the prior art is solved.

Provided in an embodiment of the present application are a Locator allocation method, apparatus, device and storage medium, the method comprising: receiving a first message sent by an ICMPv6 server, the message type of the first message being a router advertisement (RA) message, and the first message comprising a first option field, the first option field is used for indicating a segment routing (Srv6) network node identifier (Locator) based on the IPv6 (Internet Protocol Version 6) of the ICMPv6 client side. By adopting the method, the client device can automatically obtain the Srv6 Locator from the upstream server device by expanding the NDP and utilizing the RA message of the ICMPv6 message.

The present disclosure provides a system (108) and a method (600) for handling at least one data packet between a visited network and a home network. The system (108) includes at least one visited network function (NF). The at least one visited network function (NF) is configured to receive at least one router advertisement (RA) message from at least one home NF and extract at least one information element (IE) associated with a user equipment (UE) (104) from the RA message. The extracted IE is stored in a memory (204) associated with the visited NF for subsequent processing. The visited NF receives at least one data packet from the home NF and handles the data packet towards the UE (104) based on the stored IE.

The invention discloses a message transmission method and device for a congestion scene, and the method is applied to a core network, and the method comprises the steps: transmitting a router notification message to user equipment at a first frequency, the router notification message carrying a network prefix required for the user equipment to access a network; in response to determining that the network congestion occurs, determining a congestion level value representing a network congestion degree, the congestion level value being in positive correlation with the network congestion degree; and sending a router notification message to the user equipment according to a second frequency corresponding to the congestion level value, the second frequency being greater than the first frequency, and the second frequency being in positive correlation with the congestion level value. According to the scheme, when the network congestion occurs, the issuing frequency of the router notification message is improved, and the probability that the user equipment successfully receives the router notification message in the network congestion scene is improved, so that the success rate that the user equipment accesses the network in the network congestion scene is improved.
