Method and device for handling of exception at side of intelligent network interface card

Abstract

The invention discloses a method and a device for handling of an exception at side of an intelligent network interface card. The method comprises the following steps that a central processing unit applies for a memory space and transfers information of the memory space to the intelligent network interface card; the intelligent network interface card obtains the information of the memory space, obtains exception information when the exception occurs and writes the exception information into the memory space; and the central processing unit obtains the exception information in the memory space. According to the method, the intelligent network interface card directly writes the exception information into a memory of a host and stores an exception log at the side of the intelligent network interface card on the host. The exception information at the side of the intelligent network interface card is recorded, so that a technical person can refer to the exception information to remove a fault, and thus the solution speed of an exception problem is improved. The method of the invention has universality and can be suitable for the existing servers or cloud systems.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for handling exceptions on the smart network card side. Background technique [0002] Cloudification is an important development direction of telecommunications equipment at present, and network and computing virtualization is one of the foundations of cloudization. The current servers are basically based on the central processing unit (such as X86) + network interface card (Network Interface Card, NIC) platform to realize network and computing virtualization. Traditional network interface cards, such as Intel's network card chip i350 / 82599, do not support network traffic protocol processing, and have certain restrictions on the support provided by network virtualization. When the network traffic is relatively large, it will consume the central processing unit. Lots of resources to process. In view of this situation, based on virtualization te...

Problems solved by technology

However, the application on the smart network card sometimes has an abnormality. When an abnormality occurs on the smart network card side, the host side may appear to be abnormal in communication with the smart network card. However, it is impossible to know what abnormality occurred on the smart network card.

Due to not knowing the abnormal information on the side of the smart network card, the abnormal problem cannot be quickly resolved
