Problems solved by technology

[0003] However, the current link bundling only considers the interfaces formed by the bundled links. After bundling these links, the interfaces are also required to have the capability of forwarding Layer 2 packets. It is required that the links bundled together for service forwarding must be of the same type, and multiple links of different types cannot be bundled for service forwarding, such as SDH / SONET-based packet encapsulation (Packet Over SDH / SONET, POS) links and Ethernet links cannot be bundled together

Embodiment Construction

[0018] Embodiments of the present invention provide a method and a communication device for transmitting messages by aggregation links. By forwarding packets received on aggregated link ports into network layer protocol packets for routing and forwarding, the bundling of different types of links is realized.

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] See first figure 1 , figure 1 It shows a schematic structural diagram of a communication device in the implementation of the present invention. The communication device is a routing device or other device. The communication device is provided with one or more aggregation interfaces, and each aggregation interface includes one or more member interfaces. The interface is used to exchange messages with the aggregation link, and the aggregation interface can be used as an outgoing interface or an incoming interface of the communication devi...

Abstract

The embodiment of the invention discloses a method for aggregation link transmission messages, which comprises the following steps: receiving the messages of a first link layer sent by the polymerization link; transforming the received messages of the first link layer into messages of a network layer; sending the messages of the network layer to corresponding outgoing ports according to destination addresses in the transformed messages of the network layer. The embodiment of the invention also discloses a communication device, which comprises a receiving module for receiving the messages of the first link layer sent by the aggregation link; a first transforming module for transforming the messages of the first link layer received by the receiving module into the messages of the network layer; a sending module for sending the messages of the network layer to the corresponding outgoing ports according to the destination addresses in the messages of the network layer transformed by the first transforming module. The method provided by the embodiment of the invention forwards the messages received from the ports of the aggregation link into the messages of the network layer for routing forwarding and realizes the binding of different types of links on the aggregation link.

Description

technical field [0001] The present invention relates to the field of communication applications, in particular to a method and a communication device for transmitting messages by aggregation links. Background technique [0002] Link aggregation (Link Aggregation) in IEEE 802.3ad refers to a method of bundling a group of physical ports together as a logical interface to increase bandwidth. IEEE 802.3ad establishes a link aggregation group ( Link Aggregation Group), which can provide higher bandwidth and higher reliability. The PPP Multilink Protocol (MP) is another link aggregation technology. By bundling multiple Point-to-Point Protocol (PPP) links together, it provides greater bandwidth and realizes Fast forwarding of data. [0003] However, the current link bundling only considers the interfaces formed by the bundled links. After bundling these links, the interfaces are also required to have the capability of forwarding Layer 2 packets. It is required that the links bun...
