Embodiment Construction

[0067] The core of the present invention is to use the physical layer multiplexing chip and the characteristics of the physical layer multiplexing cascading device composed of multi-level physical layer multiplexing chips to make the MAC layer forwarding chip on the line interface card in the network access equipment directly communicate with the One or more physical layer multiplexing chips or physical layer multiplexing cascading devices are connected to provide users with a variety of different rate interfaces, and use the physical layer multiplexing chip to aggregate the services of multiple low-speed physical ports into one MAC layer forwarding chip high-speed interface, thereby simplifying the design of equipment line cards and reducing network access costs.

[0068] For this connection mode, when receiving an uplink signal, the physical layer multiplexing chip / physical layer multiplexing cascading device records the corresponding relationship between the uplink signal an...

Abstract

The invention relates to a network access device, which comprises interface card. Wherein, said interface card comprises media access control MAC layer transfer chip, at least one connected physical layer complex chip, or at least one group of connected physical complex connector. Said invention also provides a method for transferring data at network access device, which marks the physical interface mark on the service data frame when the low-speed physical interface service is collected to the high-speed interface, the MAC layer transfer chip based on the MAC address transfer list replaces the physical interface mark of data frame, to transfer the service data correctly. The invention can simplify the wires of network access device, and reduce access cost.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network access device and a data forwarding method thereof. Background technique [0002] Ethernet has the advantages of high transmission rate, rich network software, simple installation and connection, convenient use and maintenance, etc., so it has become one of the international popular LAN standards. With the maturity of Gigabit Ethernet and the emergence of 10 Gigabit Ethernet (10Gb / s, IEEE802.3ae), coupled with the low-cost direct architecture of Gb and 10Gb Ethernet technologies on optical fibers (fiber-optic Ethernet) and some related Standards and protocols: With the emergence of rapid spanning tree (802.1w), Ethernet has begun to enter the field of MAN and WAN. Currently, the specifications of physical layer access chips on the market include chips such as 10 / 100 Mbps adaptive, GE (Gigabit Ethernet), and 10GE (10 Gigabit Ethernet). The main function o...
