Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 is a schematic diagram of some embodiments of a value added service providing method according to the present invention. Preferably, this embodiment may be performed by the customer premise gateway CPE of the present invention. The method comprises the following steps:
and step 11, the user side gateway provides the value-added service list capable of being purchased and the current access equipment list to the user terminal, so that the user terminal displays the value-added service list capable of being purchased and the current access equipment list to the user, and the user subscribes corresponding value-added services for different current access equipment.
In some embodiments of the present invention, different current access devices in the current access device list correspond to different MAC addresses.
And step 12, adding a Service Type field and a Service Code field for the VxLAN message by the user side gateway according to the value added Service ordered by the user.
Fig. 2 is a schematic diagram of a free field of a VxLAN message in some embodiments of the present invention. As shown in fig. 2, 4 bytes in the message header of the VxLAN 8 bytes are reserved bytes, which are not used so far, and the above-mentioned embodiment of the present invention uses these 4 bytes to implement the subscriber subscription service gateway side management. The upper 1 byte is defined as a "Service Type" field to indicate a Service Type selected by the user. The lower 3 bytes are defined as a "Service Code" field to identify different value added services provided in the metro network. As shown in FIG. 3, the "Service Code" field can identify a range of 0 ~ 2^24 (about 1677 ten thousand), representing the value added Service ID of the MAN.
FIG. 3 is a diagram illustrating assignments of a Service Type field and a Service Code field in some embodiments of the invention. FIG. 3 defines several common service types, where type 0(00000000) indicates that the user has not subscribed to the service, and the message is forwarded directly to the Internet; type 1(00000001) indicates a single service, i.e. the user is subscribed to only a single value added service; type 2(00000010) indicates a composite service, i.e. a user subscribes to a composite service, which may include two or more services; type 3 (00000011) represents a local Private Network (VPN) interconnection user; type 4(00000100) represents a wide area network VPN interconnection user; type 5(00000101) represents a wide local inbound cloud user.

In the case where the user subscribes to the composite Service, the "Service Type" fields are 00000010, and different "Service Code" fields may be used to represent different types of composite services, for example: enterprise monitoring combination services, enterprise security combination services and other combination services.
It should be additionally noted that the collocation configuration of the composite service is not defined by the user, but is combined by the provider of the metro network value added service (usually the telecom operator). For example, an enterprise user wants to order a traffic cleansing and big data analysis service for a portal web server, which is a typical security combination service, an operator provides a combination after testing according to a single service provided in a metropolitan area network, and provides a service Code for the combination, so that a more convenient choice is provided for the user, and a certain benefit can be provided from the cost by a packaging selling mode.
