Problems solved by technology

Since the IOAM entry node needs to complete the insertion of the IOAM header, it needs to determine which IOAM function option TLVs and the length of each IOAM function option TLV are included in the IOAM data content. These information are added by the network administrator according to the configuration on each IOAM transmission node Determine and deliver to the IOAM entry node. As mentioned above, the configuration on the IOAM transmission node is usually more complicated and easy to change, so this method of manually sending information to the IOAM entry node to achieve IOAM encapsulation increases network management. burden on staff and error-prone

Embodiment 1

[0095] Figure 4 It is a schematic diagram of automatically implementing IOAM encapsulation by extending DHCP in an embodiment of the present invention. In this embodiment, the IOAM entry node and the IOAM centralized configuration point will perform the following steps:

[0096] Step 11: The network administrator performs IOAM configuration on the IOAM transmission nodes through the network management system, and saves the IOAM configuration information of each IOAM transmission node in the IOAM centralized configuration point.

[0097] In this embodiment, the IOAM centralized configuration point is an IOAM configuration server connected to the network management system, and the server also serves as a DHCP server for dynamically assigning IP addresses.

[0098] Step 12: The IOAM entry node sends a DHCP request message carrying the IOAM transport node identifier and IOAM configuration request information to the IOAM configuration server.

[0099] Figure 5 Is the format di...

Embodiment 2

[0105] Figure 7 It is a schematic diagram of automatic realization of IOAM encapsulation by extending PCEP. In this embodiment, the IOAM entry node and the IOAM centralized configuration point will perform the following steps:

[0106] Step 21: The network administrator configures the IOAM for the IOAM transmission nodes through the network management system, and saves the IOAM configuration information of each IOAM transmission node in the IOAM centralized configuration point.

[0107] In this embodiment, the centralized IOAM configuration point is the network management itself.

[0108] Step 22: The IOAM entry node sends a PCEP request message carrying the IOAM transport node identifier and IOAM configuration request information to the network manager.

[0109] Figure 8 is the format diagram of the PCEP message, such as Figure 8 As shown, the PCEP request message includes a group of objects (Objects) in TLV form, by adding a new object TLV, wherein the Type field repr...

Abstract

The present invention discloses a method and device for automatically implementing IOAM package. The method includes the following steps that: an IOAM ingress node transmits a first message carrying IOAM configuration request information to an IOAM centralized configuration point; the IOAM ingress node receives a second message which is sent by the IOAM centralized configuration point and carriesthe IOAM configuration information of each IOAM transmission node; and the IOAM ingress node performs IOAM package on a service data message according to the IOAM configuration information of each IOAM transmission node.

Description

technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for automatically encapsulating In-situ Operations, Administration and Maintenance (IOAM, In-situ Operations, Administration and Maintenance or In-band Operations, Administration and Maintenance). Background technique [0002] IOAM is a data communication network operation, management and maintenance (OAM) technology newly proposed by the industry. This technology is currently in a rapid development stage under the joint promotion of the industry, and is being developed by the Internet Engineering Task Force (IETF, Internet Engineering Task Force) of the International Organization for Standardization. Carry out standardized work. [0003] IETF's IOAM series proposals draft-brockners-inband-oam-requirements, draft-brockners-inband-oam-transport, and draft-brockners-inband-oam-data respectively describe the source of IOAM requirements, encapsulation for...
