Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Fig. 1 is a schematic diagram illustrating a conventional measurement method of end-to-end link metrics of two-layer to three-layer services. As shown in fig. 1, two-layer pseudo wires are deployed between an access layer and a convergence layer of an IPRAN bearer network, and L3VPN deployment is employed above the convergence layer. Traditional end-to-end service measurement adopts different measurement technologies according to a service deployment mode: the mobile bearer service carries out link index measurement on the current network online measurement of a two-layer access section based on Y.1731; the on-line Measurement of the three-layer service segment is based on TWAMP (two-way Active Measurement Protocol) to perform link index Measurement, and TWAMP can meet the end-to-end Measurement requirement of the existing network link, so TWAMP can also be called as a three-layer Measurement technology. After the operation and maintenance personnel obtain the segmented measurement results through two measurement methods realized by different technologies, the Service support system splices the measurement indexes of the segments and outputs an end-to-end SLA (Service Level Agreement) report index.
However, the 5G network needs to have high reliability, and currently, the link indexes finally obtained by the end-to-end service online measurement method implemented by two different technologies can only be spliced according to the segmented measurement result, so that the link indexes finally output are inaccurate, have large errors, are complex in implementation process, and are difficult to maintain various protocols. In order to solve the above problems, the present disclosure provides a packet transmission method, which implements an improved end-to-end service measurement scheme based on TWAMP in an L2+ L3VPN service mode, and a schematic diagram of the scheme is shown in fig. 2, and the scheme can enhance network performance measurement means and simplify the use of measurement technology, thereby providing an end-to-end SLA measurement report for a client.
Some embodiments of the disclosed message transmission method are first described in conjunction with fig. 3.
Fig. 3 illustrates a flow diagram of a message transmission method according to some embodiments of the present disclosure. As shown in fig. 3, the present embodiment includes steps S301 to S304.
In step S301, the core layer device performs IP encapsulation on the TWAMP test packet of the bidirectional active measurement protocol to obtain a UDP test packet, and sends the UDP test packet to the three-layer virtual ethernet interface of the convergence layer device.
In an MPLS (Multi protocol Label Switching) forwarding network, L3 layer (core layer) devices serve as transmitting terminals, and PDU padding of TWAMP test packets is performed according to a packet field rule defined in a TWAMP protocol. Table 1 shows a schematic structural diagram of a UDP test packet. The UDP test message comprises a two-layer protocol header, a multi-protocol label switching protocol header, a destination MAC address, a source MAC address, a destination IP address, a source IP address, a destination UDP port, a source UDP port and a TWAMP test message. When three-layer forwarding is performed between the core layer device and the convergence layer device, the fields of the destination MAC address, the source MAC address, the destination UDP port, and the source UDP port in the newly defined UDP test message are not required to be filled, and are directly IP-encapsulated and forwarded to the L3VE interface of the convergence layer device (bridge device).

Figure BDA0002340919050000061
In step S302, the convergence layer device performs address resolution according to the destination IP address of the UDP test packet to obtain a destination MAC address and a destination UDP port, fills the destination MAC address and the destination UDP port into the UDP test packet, and sends the filled UDP test packet to the access layer device through the two-layer virtual local area network interface.
The convergence layer device performs ARP (Address Resolution Protocol) Resolution according to a target IP Address (i.e., an IP Address of a base station), searches for an MAC Address and a target UDP port of a two-layer VLAN interface in a network, correspondingly fills a UDP test packet to perform packet repackaging, and forwards the repackaged packet to the access layer device through a two-layer channel from the convergence layer device to the access layer device.
In step S303, the access stratum device identifies the UDP test packet according to the destination MAC address and the destination UDP port of the UDP test packet; exchanging the destination MAC address and the source MAC address of the UDP test message, exchanging the destination IP address and the source IP address of the UDP test message, exchanging the destination UDP port and the source UDP port of the UDP test message and sending the UDP test message back to the core layer device through the base station access port of the access layer device.
After the UDP test packet reaches the access layer device, the access layer device identifies that the UDP test packet is a test stream according to the destination MAC address and the destination UDP port number, and needs to send the UDP test packet back to the core layer device along the original path of the service. When the access layer device sends the UDP test message back to the core layer device, the access layer device may send the UDP test message to the two-layer vlan interface of the convergence layer device, perform address resolution by the convergence layer device according to the destination IP address of the UDP test message to obtain the destination MAC address and the destination UDP port, fill the destination MAC address and the destination UDP port into the UDP test message, and send the filled UDP test message to the core layer device through the three-layer vlan interface.
In step S304, the core layer device determines an end-to-end link indicator of the two-layer to three-layer service according to the returned UDP test packet.
For example, the core layer device may determine the end-to-end bidirectional link delay of the two-layer to three-layer service according to the receiving timestamp of the returned UDP test packet.
In this embodiment, link index measurement of the access segment of the two-layer virtual private network is implemented by improving a TWAMP-based link index measurement technology of the three-layer virtual private network, so that link index measurement technologies applied to the two-layer virtual private network and the three-layer virtual private network are unified, the link index measurement technologies between the two-layer virtual private network and the three-layer virtual private network are seamlessly connected, and end-to-end link index online measurement of services from the two layer to the three layer of the bearer network is implemented. The embodiment reduces the alternate use of different measurement technologies, thereby simplifying the network deployment and maintenance work; due to the fact that segmented measurement and measurement result splicing are not needed, the end-to-end link index of the two-layer to three-layer service can be determined more accurately and efficiently.
The following describes how to determine the end-to-end link metrics for layer two to three services. The present embodiment includes steps S3041 to S3043.
In step S3041, the core layer device exchanges the destination IP address and the source IP address of the UDP test packet sent back.
In step S3042, the core layer device matches the sent UDP test packet according to the exchanged destination IP address and source IP address of the sent back UDP test packet;
in step S3043, the core layer device determines an end-to-end delay, jitter, and packet loss rate of the two-layer to three-layer service by using the TWAMP test message in the returned UDP test message and the TWAMP test message in the UDP test message.
For example, the core layer device may determine the end-to-end bidirectional delay of the two-layer to three-layer service by using the receiving timestamp carried in the TWAMP test message in the returned UDP test message and the sending timestamp carried in the TWAMP test message in the sent UDP test message. Those skilled in the art should understand that, according to the TWAMP test packet in the returned UDP test packet, the measurement of jitter and packet loss rate may also be implemented based on the TWAMP protocol.
