Abstract: An edge synchronization platform that facilitates mesh network routing via dynamic routing tables is disclosed. A node in the mesh network obtains a network communication. The node performs a wrapping operation on the network communication to generate a wrapped data packet. The wrapped data packet includes a destination indicator. The node identifies a recipient node for the wrapped data packet using a dynamic routing table. The node then sends the wrapped data packet to the recipient node.

Abstract: A system described herein may provide a technique for the rate-controlled forwarding of traffic to a base station of a radio access network (“RAN”). The rate of the forwarding of the traffic may be based on a latency sensitivity of the traffic, metrics associated with the base station, and an ingress capacity of the base station. The metrics associated with the base station may include congestion and/or load metrics, radio frequency (“RF”) metrics, or other suitable metrics. The latency sensitivity of the traffic may be determined based on a source and/or destination of the traffic, a network slice associated with the traffic, or other suitable traffic attributes. After receiving the rate-controlled traffic, the base station may perform scheduling and/or queueing of the traffic in order to wirelessly provide the traffic to one or more User Equipment (“UEs”).

Abstract: A method includes: A control plane of a network device obtains a first MAC entry, and sends the first MAC entry and a first identifier to a forwarding plane of the network device. The forwarding plane stores the first MAC entry in a first MAC table, and a state of the first MAC entry is set to a valid state. The forwarding plane changes the state of the first MAC entry to an invalid state after first preset duration elapses and when a first preset condition is met, and sets invalid duration for the first MAC entry. The first preset condition is that the forwarding plane does not receive traffic corresponding to a first MAC address within the first preset duration after storing the first MAC entry.
