Embodiment Construction

[0061] The core of the present invention is: in a network system where the carrier's Ethernet is connected to the customer network, the customer network accesses the carrier's Ethernet through the service access port on the edge device of the carrier's Ethernet, and the carrier's Ethernet is the The network assigns a MAC address that can uniquely identify the service access port, which is called the service access MAC address here. In order to support different customer services, the operator allows multiple service access MAC addresses to be allocated to the same service access port, and these MAC addresses will be used when encapsulating the outer MAC header of the data packet.

[0062] The addressing mode and address space of the above-mentioned service access MAC address may be independent of the address space and addressing mode of the client MAC address. These service access MAC addresses can be controlled and managed by the carrier Ethernet, and their number is limited ...

Abstract

This invention discloses a method and a system for transmitting data between the Ethernet of a business runner and a customer network including: the Ethernet of a business runner configures service access MAC address for customer network , which is the address of a service access port on the Ethernet edge device, before a data packet is sent into the Ethernet of the business runner from a customer network, it is packaged with an outer MAC head, the source address of which is the source service access MAC address, the destination address is the objective service access MAC address, said data packet is sent to another customer network via the business runner Ether net. This invention realizes that the Ethernet of a business runner screens the MAC address in the customer network and becomes a manageable one.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and a system for transmitting data between an operator's Ethernet and a client network. Background technique [0002] Due to its advantages of low cost, mature standard and flexible technology, Ethernet technology has not only been widely used in enterprise LAN environment, but also provided to customers as a new access service by telecom operators. However, the traditional Ethernet forwards and exchanges data through learning the MAC address. Since the MAC address does not have a hierarchical structure like the IP address, when different customer networks transmit data through the carrier Ethernet, according to the existing In the Ethernet data forwarding method, the carrier Ethernet network must store and process the MAC address inside the customer network in order to transmit and forward data. In fact, the operator's network will provide services for a large numb...
