An operation request generating method, including a generation device generates a first operation request that requests to perform an operation on a first packet, where the first operation request includes first assignment content and information used to indicate a first assignment location, the first assignment location is a location in the first packet, the first assignment content is data used to assign a value to the first assignment location, and the information used to indicate the first assignment location includes an identifier of a type of a first packet header, a first offset, and a first length, where the first packet header is a packet header in the first packet, and the first offset is an offset relative to a start location of the first packet header, and the generation device sends the first operation request to a description device or a receiving device.

Operation request generating method, device, and system

The application provides an operation request generating method. The method includes: a generation device generates a first operation request that requests to perform an operation on a first packet, where the first operation request includes first assignment content and information used to indicate a first assignment location, the first assignment location is a location in the first packet, the first assignment content is data used to assign a value to the first assignment location, and the information used to indicate the first assignment location includes an identifier of a type of a first packet header, a first offset, and a first length, where the first packet header is a packet header in the first packet, and the first offset is an offset relative to a start location of the first packet header; and the generation device sends the first operation request to a description device or a receiving device.

A network element (NE) comprising a processor configured to transmit a message to a domain names system (DNS) server, wherein the message comprises a virtual service internet protocol (VSIP) version six (VSIPv6) address corresponding to a service associated with an internet protocol version four (IPv4) address. Also disclosed is a method comprising associating a remote host internet protocol (IP) version six (IPv6) address with a private IPv4 address in a stateful binding table, and associating a local service IPv4 address with a local service VSIPv6 address in a stateless binding table.

IPv4 data center support for IPv4 and IPv6 visitors

A network node for detecting failures in a Dual Stack Lite (DS-Lite) tunnel, comprising a processor configured to obtain a domain name that identifies a first node, create the DS-Lite tunnel to the first node using the domain name, initiate a first bidirectional forwarding detection (BFD) session to the first node, transmit a plurality of BFD data packets within the DS-Lite tunnel, and detect a failure within the DS-Lite tunnel using the BFD data packets.

DS-Lite with BFD support

An apparatus comprising a memory, and a processor coupled to the memory and configured to receive a mapping rule that associates a downstream internal Internet Protocol version four (IPv4) address prefix to an upstream external IPv4 address prefix, receive a first IPv4 packet from an upstream network node with a destination address field comprising an external IPv4 address comprising the external prefix, and perform a first network address translation IPv4 to IPv4 (NAT44) process by replacing the external IPv4 address in the first IPv4 packet's destination address field with an internal IPv4 address based on the mapping rule, wherein the internal IPv4 address comprises the internal prefix and a port set identifier (ID) associated with set of destination ports at a downstream node assigned to receive the first IPv4 packet.

Stateless NAT44

The present disclosure relates to the field of communications, and discloses a method for determining path pre-congestion. The method is applicable to an Ethernet path. Pre-congestion is determined and flagged through an ingress node or an intermediate node in the Ethernet path, and a pre-congestion status indication packet is sent by an egress node to the ingress node or a policy server, so that the ingress node or the policy server obtains pre-congestion information of the Ethernet path, and notify an application function entity AF of performing admission control. When the method in the present disclosure is used, problems of packet loss and excessively long time delay caused by the conventional congestion control technology may be avoided, thereby ensuring user experience of existing services.

Method, apparatus, and system for judging path congestion

A management method for network address translation includes: obtaining a network resource section of a client and using state information of the network resource section; adjusting the network resource section according to the using state information of the network resource section, where the adjusted network resource section can provide a network resource for all connections of the client; establishing a network address translation entry for each connection of the client according to the adjusted network resource section; and establishing a corresponding log record for the network resource section.
