The present disclosure provides a packet encapsulation method, including: determining a segment routing-traffic engineering (SR-TE) path; generating, according to a segment identifier (SID) of each node in the SR-TE path, an SID list, where each node supports a plurality of unified-SID encapsulation types (UETs) corresponding to SIDs of different lengths, and in the SID list, the SID of at least a node serving as an intermediate node of the SR-TE path is the SID having the non-longest length in the plurality of SIDs corresponding to the node; forming a segment routing header (SRH) from the SID list; and encapsulating an initial packet with the SRH to obtain a final packet. The present disclosure further provides a packet forwarding method, a UET announcement method, an electronic device, and a computer-readable storage medium. The final packet obtained by the packet encapsulation method has a higher load rate.

Technologies for managing network traffic through heterogeneous fog network segments of a fog network include a fog node deployed in a fog network segment. The fog node is configured to receive a fog frame that includes control instructions. The fog node is further configured to perform a route selection action to identify a preferred target fog node based on the control instructions, perform action(s) based on the control instructions and network characteristic(s) of the fog network segment relative to corresponding network characteristic(s) of the different fog network segment, and generate updated control instructions based on at least one network characteristic of the different fog network segment. Additionally, the fog node is configured to replace the original control instructions of the received fog frame with the updated control instructions and transmit the received fog frame with the updated control instructions to the preferred target fog node. Other embodiments are described and claimed.

Some embodiments of the invention provide a method of facilitating routing through a software-defined wide area network (SD-WAN) defined for an entity. A first edge forwarding node located at a first multi-machine site of the entity, the first multi-machine site at a first physical location and including a first set of machines, serves as an edge forwarding node for the first set of machines by forwarding packets between the first set of machines and other machines associated with the entity via other forwarding nodes in the SD-WAN. The first edge forwarding node receives configuration data specifying for the first edge forwarding node to serve as a hub forwarding node for forwarding a set of packets from a second set of machines associated with the entity and operating at a second multi-machine site at a second physical location to a third set of machines associated with the entity and operating at a third multi-machine site at a third physical location. The first edge forwarding node serves as a hub forwarding node to forward the set of packets from the second set of machines to the third set of machines.

A method for cross datacenter service-to-service communication over a shortest network route using mesh gateways. A mesh gateway receives a protocol message from a first service directed to a second service, identifies destination information associated with the second service, recognizes a routing configuration for routing the protocol message, determines a network route based on the routing configuration, and forwards the protocol message to another gateway associated with the second service over the determined network route.
