Method and device for protecting HQoS by using multiple boards

Technical field

The present invention relates to the field of network communications, and more particularly to a method and apparatus for protecting HQoS using a multi-board.

Background technique

With the development of technology and the times, Ethernet technology has increasingly become an important technical means of social production and office. With the rapid growth of smart terminal holdings, the mobile Internet industry is also becoming more mature. The wireless network is developing to ALL IP (all-network IP), which requires a large capacity of the aggregation layer device and a fast service reply mechanism to ensure that the service is never interrupted and highly reliable.

A traditional Ethernet aggregation layer device is usually equipped with a service processing board and multiple service interface cards. This has certain security problems. When the service card of the aggregation layer device fails, all services connected to it will be interrupted. At the same time, a single service processing board will cause the service to be interrupted when upgrading the aggregation device.

For this reason, some inter-board protection technologies such as LAG (Link Aggregation Group) have been deployed. Users need to deploy HQoS (Hierarchical Quality of Service) policies on LAGs and multi-boards to ensure more. Unified management and hierarchical scheduling of users, multiple services, multiple traffic. When the motherboard card fails, the backup board is switched to the standby board in a short time. The backup board continues to provide the expected HQoS. This avoids the HQoS redeployment and may cause important service delays and congestion. This ensures the QoS (Quality of Service).

Preferred embodiment of the invention

The embodiments of the present invention are described in detail below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The embodiment of the invention provides a method for protecting HQoS by using a multi-board to protect the HQoS configuration policy of the Ethernet aggregation layer device. The VOQ-ID is encoded for all service boards in turn by the motherboard card, and then the allocated VOQ-ID is synchronized with the HQoS configuration information to all the standby boards. All service boards apply for VOQ resources and complete HQoS configuration. When the motherboard card fails. The faulty motherboard card is offline, the port protection is switched, the spare board is updated to the VOQ-ID of the offline faulty motherboard card, and the board is elected as the motherboard card.

The Ethernet aggregation layer device device, as shown in FIG. 1 , includes a motherboard card (main service processing board) and multiple spare boards (alternative service processing boards), and the service interface card simultaneously connects multiple services through the connector. Handle the board. When the service processing board is in the normal working state, the connector enters the service processing card that belongs to the current port according to the default access relationship. Each service processing board not only allocates VOQ (Virtual Output Queue) resources for the local forwarding service, but also allocates VOQ resources for forwarding services to other service processing boards. Each HQoS policy is configured for each user. The business processing boards each apply for VOQ resources.

In the embodiment of the present invention, the method for protecting HQoS by using a multi-board, as shown in FIG. 2, includes the following steps:

In step S10, the HQoS configuration information is sent to all the boards for storage.

In step S10, the main control board sends the user HQoS configuration information to all service processing boards. (The following is a brief description of the board), the board receives and saves the configuration information.

In step S11, the VOQ identifier (VOQ-ID) is encoded by the motherboard card as a spare board.

In step S11, the motherboard card globally manages the VOQ-ID, and the VOQ-ID is expressed as:

VOQ-ID=XXX: Node-ID: PHB;

The XXX is an arbitrary value. The Node-ID uniquely identifies the board in the system. The per-hop behavior (PHB) indicates that the packet is forwarded within the device. The PHB is different. The VOQ of packets sent to different boards is entered. It is also different. The role of VOQ-ID is: when a certain board in the system fails, only need to change the NODE-ID bit in the VOQ-ID to achieve fast traffic protection switching. The VOQ-ID resource is global. The motherboard card logically divides the VOQ-ID into bit numbers and then allocates them to the standby board to ensure that the VOQ-ID resources of each board in the system do not conflict.

Step S12: After the motherboard card synchronizes the encoded VOQ-ID and the HQoS configuration information to the standby board, the HQoS configuration of the board is completed.

In step S12, the standby board will only configure the HQoS policy after receiving the HQoS configuration information and the VOQ-ID synchronization information sent by the motherboard card. If the HQoS configuration information or the VOQ-ID synchronization information is not received, the standby card is in the Waiting for the sync status. The motherboard card and the standby board maintain the same configuration information for the HQOS configuration information delivered by the master. When the user deletes the HQoS policy, each board releases the VOQ resources. The processing of each board is independent and does not require any interaction.

Step S13: detecting whether the motherboard card is faulty, if yes, executing step S14, and if not, performing step S11 again.

Step S14: The faulty motherboard card is offline, and after the port is protected and switched, the standby board competes for the VOQ-ID of the faulty motherboard card.

In step S14, when the motherboard card fails, the connector disconnects the board from the board and accesses the standby board that is working normally. Because the encoded VOQ-ID is used to distinguish the service processing board bridged by the service interface card port, that is, when a certain service processing board in the system fails, only the NODE-ID bit in the VOQ-ID needs to be changed to achieve fast traffic. Protection switching. At this point, the access processing board is accessed. Elected as a new motherboard card, all subsequent VOQ-ID management is performed on the new motherboard card.

At this point, the system completes the troubleshooting of the faulty board and repeats step S10.

In the embodiment of the present invention, when the motherboard card is faulty, the backup card does not need to be reconfigured, and the HQoS requirement of the user is satisfied while ensuring fast switching of the traffic, and the implementation is simple and operability is strong.

The method for protecting the HQoS by using the multi-board is as follows. Referring to FIG. 3, before the step S11, the method may further include:

Step S20: Identify the roles of the motherboard card and the backup board in all the boards.

In order to facilitate the re-use of the subsequent card or the faulty card, the method for protecting the HQoS by using the multi-board is as follows. Referring to FIG. 4, after step S14, the method may further include:

Step S30: Determine whether the offline faulty board is repaired; if yes, execute step S31.

In step S30, the offline faulty board includes the faulty motherboard card in the offline line in step S14.

In step S31, the repairing board is re-routed to the standby board.

In step S31, after the offline faulty motherboard card is re-launched after the fault is repaired, as the standby board role, step S10 is re-executed.
