Problems solved by technology

[0018] In response to the above-mentioned problems, the present invention proposes a forwarding device and a flow output interface adjustment method, which increases the calculation of the bandwidth usage rate of member interfaces and the calculation of the bandwidth usage rate corresponding to each HASH value. According to the calculated bandwidth usage rate, Dynamically adjust the output interface corresponding to the HASH value, so that the business will not be affected when the HASH is unevenly abnormal, and effectively protect the business from being unaffected in the case of HASH unevenness

Embodiment 1

[0067] This embodiment is a flow output interface adjustment method, and the adjustment method includes:

[0068] Create an index table, where the index table includes Index values ​​and member output interfaces assigned to each Index value. The creation of the index table is specifically:

[0069] An index table is created when an Eth-Trunk is created or an ECMP route is generated. The index table includes the following fields: Type value, Key value, and Index value table. The Type value is an index type, and the Key value points to the Index value table. The Index value table includes an Index value and an output interface. Each Index value is assigned an output interface.

[0070] The simple process of creating an index table is as follows image 3 , an Eth-Trunk is created on the device or an ECMP route is generated, an index table is created correspondingly. The index table contains the index table type Type, Key and 0~1023 Index values, and each Index value is proporti...

Embodiment 2

[0087] This embodiment is a forwarding device, and the forwarding device includes:

[0088] An index table creation module, the index table creation module is used to create an index table, and the index table includes an Index value and a member output interface assigned by each Index value; the index table creation module is created when an Eth-Trunk is created or an ECMP route is generated index table, such as image 3 , Figure 4As shown, the index table includes the following fields: Type value, Key value and Index value table, the Type value is the index type, the Key value points to the Index value table, and the Index value table includes the Index value and the output Interface Each Index value is assigned an output interface.

[0089] The index table query module, the index table query module obtains the next hop index type according to the traffic destination IP address, obtains the index table corresponding to the current flow according to the next hop index type...

Abstract

The invention provides a forwarding device and a flow output interface adjusting method, according to the technical scheme of the invention, an index table is created according to each Eth-Trunk interface or each ECMP route, the index table comprises index table types Type and Key and 0-1023 Index values, each Index value is correspondingly allocated with a member interface, and the flow output interface adjusting method comprises the following steps of: establishing an index table according to each Eth-Trunk interface or each ECMP route; meanwhile, the equipment calculates the bandwidth utilization rate of the corresponding Eth-Trunk or ECMP member interface and the bandwidth utilization rate corresponding to the Index value in real time, and once the condition of ultra-bandwidth of the member interface is found, the member output interface corresponding to the Index value is dynamically adjusted according to the bandwidth utilization rate corresponding to each Index value; and adjusting part of member ports with ultra-bandwidth corresponding to the original Index values into member ports with sufficient bandwidth. According to the scheme, the service can be effectively protected from being influenced under the condition that the HASH is not uniform. The problem of HASH non-uniform interface ultra-bandwidth packet loss caused by complex traffic in the network is solved, and the service is effectively protected from being influenced.

Description

technical field [0001] The invention relates to the technical field of network communication, and relates to a forwarding device and a method for adjusting a flow output interface. Background technique [0002] In actual network applications, the traffic exceeds the bandwidth of a single interface due to factors such as complex network environment, unstable network, and too much specific traffic. Currently, the current solution is generally to bind multiple interfaces into a logical interface Eth-Trunk, such as figure 1 shown, or expand the output interface from a single interface to a multi-interface by ECMP, such as figure 2 shown, thereby increasing the bandwidth of the corresponding traffic output interface. When traffic is forwarded, a HASH value is calculated according to the HASH factor, and then the corresponding physical interface is selected according to the HASH value for forwarding, so as to realize load sharing among multiple physical interfaces. [0003] Eth...
