Abstract: Provided is a method and device for implementing Virtual Private Network (VPN) cross-domain, and a border node. The method includes that: a border node receives a advertisement message which carries VPN route information and is sent by a first node to a second node, wherein the border node supports Internet Protocol Version 6 Segment Routing (SRv6) capability, and the first node and the second node belong to different domains; and the border node assigns VPN identity information to a VPN route corresponding to the VPN route information, adds the VPN identity information into the advertisement message and sends the advertisement message to the second node, wherein the VPN identity information includes at least one of: a VPN Segment ID (SID) and a VPN label.

Abstract: The present disclosure provides a transmission control method, a node, a network system, and a storage medium. The transmission control method includes encapsulating, by a node, overlay service identification information corresponding to a packet in the packet, and transmitting, by the node, the packet to a next hop using an underlay network resource dedicated to a service corresponding to the overlay service identification information.

Abstract: A message sending method, a binding relationship advertising method, a message sending apparatus, a binding relationship advertising apparatus, a storage medium and an electronic device are provided. The message sending method includes: receiving a first message on a first node subjected to route aggregation; in a case where the first message matches a first Incoming Label Map (ILM) table entry preset on the first node, swapping a label of the first message into an outgoing label corresponding to a detailed Forwarding Equivalence Class (FEC) to obtain a second message; and forwarding the second message to a downstream node according to a Label Switched Path (LSP) corresponding to the detailed FEC.

Abstract: A pigment dispersant can be obtained by reacting amine-rich moieties C with at least one polymer P having one or more amine reactive groups. The amine-rich moieties C have an amine density of at least 600 mg KOH/g and are obtainable from repetitive self-reaction of at least one type of substance B and/or from cross-reaction of at least one B with at least one substance A. B is an adduct of at least one substance A and at least one linker D. The amine-reactive functionality in B and D are reacted with reactive amines in B and/or A; and if B has only one amine reactive group, then additional D and/or mixture of B and A is reacted to a previously formed C, where such an additional reaction of D and/or mixture of B and A to a formed C is repeated for 1 to 10 times.
