Embodiment 1

[0053] Such as Figure 5 As shown, in this embodiment, the data packet enters the switch chip from outside the digital microwave device, and the destination MAC address is not the digital microwave device.

[0054] This kind of packet is business data, which does not need to be processed by the digital microwave device. The destination address is not the MAC address of the digital microwave device, and it is directly forwarded at the second layer. The data will not go through the SWITCH layer-3 routing process and will not be sent to the CPU. .

Embodiment 2

[0056] As shown in FIG. 6 , in this embodiment, the data packet enters the switch chip from outside the digital microwave device, the target MAC address is the digital microwave device, and the target IP address is not the digital microwave device.

[0057] These packets are to be routed through the digital microwave equipment, and are processed in two cases: one is that the data packet enters from the broadcast port, as shown in Figure 6 (A); the other is that the data packet enters from the air interface, as shown in Figure 6 ( B) as shown.

[0058] 1. For the first case, the data packet enters from the broadcast port:

[0059] The data packet entering the device initiates an ARP request before sending it; if the requested address exists, the device learns the MAC address corresponding to the destination IP carried in the data packet;

[0060] 2. For the second case, the data packet enters from the air interface:

[0061] At this time, the MAC address of the target device ...

Embodiment 3

[0064] Such as Figure 7 As shown, in this embodiment, the data packet enters the switch chip from outside the device, the destination MAC address is the MAC address of the device, and the IP address is the device.

[0065] This kind of packet is network management data, and the target MAC and IP address are both the device, so SWITCH sends the data packet to the CPU of the device for processing. After the message reaches SWITCH, a layer-3 routing search is performed first, and the destination port is the port connected to the CPU;

[0066] SWITCH sends the data packet to the CPU for local termination.

Abstract

The invention discloses a digital microwave device including a central processing unit (CPU) in charge of generating network-management data of a network element which the CPU is in, searching a route in a data package forwarding process and sending and receiving the network management data through an interface between the CPU and a switching chip; the switching chip which is in charge of data package forwarding and provided with a three-layer routing and two-layer forwarding function; a modem in charge of data package encoding and decoding, sending the data packages to an intermediate-frequency section for transmission and parsing the data received by the intermediate-frequency section; and a route synchronization module in charge of synchronizing route information and ARP protocol information to the switching chip. The invention also discloses a network-management data forwarding method applied to the above-mentioned digital microwave device. Through adoption of the technical scheme of the invention, the single three-layer interface is arranged and a single IP address is used and the three-layer routing function is realized so that IP addresses are saved and networking flexibility of the microwave network management is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a digital microwave device and a network management data routing method thereof. Background technique [0002] As the forerunner of modern wireless communication, microwave communication has always played a pivotal role in the field of communication. As a fast communication method, it plays an indispensable role in mobile networks. No matter in the mobile access network, or in the mobile metro network and core network, microwave equipment can be seen everywhere, especially in emergency communication, microwave is an irreplaceable means. The monitoring and management of microwave network elements has increasingly become the focus of attention, which is the so-called DCN (Data Connection Network, network management data) channel. [0003] The information dissemination between microwave sites is carried out through the ground line-of-sight, which is a point-to-point tr...
