Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] A method for protecting HQoS using multiple boards, used to protect the HQoS configuration policy of the Ethernet convergence layer device, the device, such as figure 1 As shown, it includes a main board (main business processing board) and multiple spare boards (standby business processing boards), and the service interface card is connected to multiple business processing boards through connectors at the same time. When the service processing board is in the normal working state, the connector will follow the default access relationship, and the packets entering from the port of the servic...

Abstract

The invention discloses an HQoS protection method and an HQoS protection device through multiple board cards. According to the method, an VOQ-ID is coded for all business board cards in turn via a main board card; then the allocated VOQ-ID and HQoS configuration information are synchronized to all standby board cards, and all the business board cards respectively apply for VOQ resources and complete HQoS configuration; and when a fault occurs on the main board card, the fault main board card is offline, port protection switching is performed, and the standby board cards are updated to the VOQ-ID of the offline fault main board card and selected to be the main board card through competition. The device is corresponding to the method. When the fault occurs on the main board card, rapid traffic protection switching to the standby board cards can be realized by only changing the NODE-ID position in the VOQ-ID so that realization is easy and operability is high.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a method and device for protecting HQoS by using multiple boards. Background technique [0002] With the development of science and technology and the times, Ethernet technology has increasingly become an important technical means for social production and office work. With the rapid growth of smart terminal holdings, the mobile Internet industry is also becoming increasingly mature. The wireless network is developing towards ALLIP (all-network IP), which requires a large capacity of the aggregation layer equipment and a fast service recovery mechanism to ensure that the service will never be interrupted and highly reliable. [0003] Traditional Ethernet aggregation layer devices are usually equipped with one service processing board and multiple service interface cards, which pose certain security issues. When the service board of the aggregation layer device fails...
