A packet processing method and device are provided, to save CPU resources consumed by parsing a packet. The method includes: parsing, by an intelligent network interface card, a received first packet to obtain an identifier of the first packet; updating, by the intelligent network interface card, a control field of a first memory buffer based on the identifier of the first packet; storing, by the intelligent network interface card, a payload of the first packet or a packet header and a payload of the first packet into the first address space through DMA based on an aggregation position of the first packet; aggregating, by a host, the first address information and at least one piece of second address information based on an updated control field in the first mbuf; and reading, by a virtual machine, address information, to obtain data in an address space indicated by the address information.

The disclosed technology relates to forwarding a packet in a network. The packet is received at a node, where the packet is encapsulated by a network service header (NSH) including a service path header that identifies a service path. The service path is associated with a treatment value that directs subsequent nodes to treat the encapsulated NSH packet with a quality of service treatment. A forwarding table stored in the node is evaluated to identify the service path and the treatment value of the encapsulated NSH packet and a quality of service treatment is determined for the encapsulated NSH packet. The encapsulated NSH packet is forwarded to the subsequent nodes based on the service path indicated in the forwarding table and in accordance with the quality of service treatment corresponding to the treatment value identified in the forwarding table.

This application relates to a distributed software-defined network (“DSDN”) for dynamically configuring and managing a wireless communication network. A plurality of DSDN nodes are connected to each other via a plurality of communication paths. Each communication path directly connects two DSDN nodes. Each DSDN node can provide DSDN configurations across diverse and disparate networks by normalizing its data plane network traffic through translation and packet encapsulation. Furthermore, the DSDN node can provide an architecture tolerant of network interruptions and network system fluctuations. For example, in the case of any one of the DSDN node's network interruptions from other DSDN nodes, the DSDN can provide network reconfiguration using network configuration rules stored in a control plane of each DSDN node. Therefore, various embodiments can increase network reliability by the multiple nodes within a software-defined network independently managing its control plane in response to changed network conditions.
