Embodiment 1

[0029] Such as figure 1 As shown, the present invention provides a preferred service data transmission device 100, including: a receiving unit 102, configured to receive service data redirected to a specified port in the switch chip for internal loopback, wherein redirected to The data volume of the business data on the designated port does not exceed the rated data volume corresponding to the bandwidth of the designated port for internal loopback; the loopback unit 104 is used to carry out internal loopback to the business data in the designated port; the sending unit 106 uses It is used to send the service data after the internal loopback to the L2VPN through the designated port.

[0030]In the preferred embodiment above, the switch chip redirects the received service data to the specified port inside the switch chip, and after the service data is internally looped back at the specified port, the service data is sent to the L2VPN, and the input port of the switch chip The d...

Embodiment 2

[0040] based on Figure 4 As shown in the preferred service data transmission device, the present invention also provides a preferred service data transmission device, such as Figure 4 As shown, the specific steps of the method include:

[0041] S402: The designated port used for internal loopback in the switch chip receives the business data redirected to the designated port, wherein the data volume of the business data redirected to the designated port does not exceed the corresponding bandwidth of the designated port used for internal loopback The rated data volume;

[0042] S404: Perform an internal loopback on the business data within the specified port;

[0043] S406: Send the service data after the internal loopback to the L2VPN through the designated port.

[0044] In the preferred embodiment above, the switch chip redirects the received service data to the specified port inside the switch chip, and after the service data is internally looped back at the specified ...

Abstract

The invention discloses a business data transmission method and a business data transmission device. The method comprises the following steps of: by using a designated port for internal loop back in an exchange chip, receiving business data redirected onto the designated port, wherein the data quantity of the business data redirected onto the designated port does not exceed the rated data quantity corresponding to bandwidth for internal loop back in the designated port; carrying out internal loop back on the business data in the designated port; and transmitting the business data subjected to the internal loop back to L2VPN through the designated port. With the adoption of the method and the device, the technical problem in the prior art that as data is discarded at an input port of the exchange chip, a system enters slow start to cause low data transmission efficiency is solved, so that the technical effects of improving the data transmission efficiency and improving the bandwidth utilization are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a service data transmission method and device. Background technique [0002] Multiprotocol Label Switching (MPLS for short) Layer 2 Virtual Private Network (Virtual Private Network of 2 Layers, L2VPN for short) provides Layer 2 VPN services based on MPLS networks, enabling operators to Provides Layer 2 VPN based on different data link layers. To put it simply, MPLS L2VPN is to transparently transmit user's Layer 2 data on MPLS network. From the user's point of view, the MPLS network is a Layer 2 switching network, which can establish Layer 2 connections between different nodes. L2VPN includes Virtual Private Wire Service (VPWS) and Virtual Private LAN Service (VPLS). [0003] Transmission Control Protocol (Transmission Control Protocol, referred to as TCP) window (Windowing) works as follows: the client sends an information segment to the service provider edge (Provider Edge...
