This application provides a method for forwarding a packet in an SRv6 service function chain, an SFF, and an SF device, and belongs to the field of communication technologies.

System and method for unmarshalled routing

In distributed object computing, messages from a source node to a destination node are often required to be routed via one or more intermediate nodes. In order to enhance efficiency of the relay process, a message envelope of a message may include a node list field that specifies the routing path of the message. The communication protocol for communicating the message may specify that when a message is received into a particular node, the node analyzes the node list field. If the identity of the node is last in the node list field, then the node is the destination node and thus the node unmarshals the message. Otherwise, the node forwards the message to the next node in the field list without unmarshalling the message.

NAME-BASED ROUTING SYSTEM AND METHOD

An advanced routing system and protocol (referred to herein as “Route Exchange” or “REX”) hides familiar IPv4 and IPv6 addresses and replaces traditional routing logic with words and relationships between named elements. Among other things, this makes IP routing tables significantly easier to understand. In addition, a single routing scheme can be used for any combination of private networks, public networks, IPv4 addressing models, and IPv6 addressing models. Underneath the words lie real IP addresses that move the packets from place to place. These routing addresses abstract away the underlying network.

Packet flow control in a header of a packet

Techniques for controlling packet flows are described. In an example, a packet is sent on a virtual network. The packet's header includes scoping data that indicates a network boundary within which the packet is permitted and/or prohibited to flow. A network virtualization device of a substrate network receives the packet. The network virtualization device determines the scoping data from the header and, based on network configuration information, determines the forward flow of the packet. If the forward flow falls within a permitted network boundary indicated by the scoping data, the network virtualization device sends the packet forward. Otherwise, the packet is dropped.

Computational accelerator for storage operations

A system includes a host processor, which has a host memory and is coupled to store data in a non-volatile memory in accordance with a storage protocol.

The NIC processes the data records in the data packets that are received in order in each flow from a peer computer and extracts and writes the data to the host memory, and when a data packet arrives out of order, writes the data packet to the host memory without extracting the data and processes the data packets in the flow so as to recover context information for use in processing the data records in subsequent data packets in the flow.
