Abstract
A communication method for interworking of local heterogeneous link protocols, includes the following steps: when the type of an input interface of a data packet is a predefined type, remove link layer information of the data packet according to a link protocol of the input interface; transmit the data packet to an output interface; a Provider Edge (PE) encapsulates the data packet according to a link protocol of the output interface and transmits the encapsulated data packet through the output interface. The present invention also discloses a communication apparatus for interworking of local heterogeneous link protocols, including: an input interface, an output interface and a data processor. The present invention processes data packets from specific interfaces and directly transmits the data packets to output interfaces, thereby implementing the interworking of local heterogeneous link layer protocols and smooth upgrading of networks.
