Background
With the development of technologies such as internet, cloud computing, internet of things, and mobile internet, especially with the arrival of mobile internet, the requirement for the transmission performance of the network is higher and higher. Users desire faster and lighter-weight network communications, which places higher demands on the bandwidth and latency of network transmissions. Rdma (remote direct Memory access) technology is called remote direct Memory access (rdma), and is generated to solve the delay of client and server data processing in network transmission. It transfers data directly from the memory of one computer to another without the intervention of both operating systems. This allows high throughput, low latency network communications, particularly suitable for use in massively parallel computer clusters. To be ethernet compatible, RDMA defines both rock (a network protocol that allows Remote Direct Memory Access (RDMA) over ethernet), IWARP implementations over ethernet, making RDMA applicable over traditional ethernet.
However, RDMA is still a new concept for users and operation and maintenance personnel, and cannot be used, managed and monitored by the hands quickly.

Claims (10)
1. A method for managing ROCE network card resources is characterized by comprising the following steps:
responding to the system startup, and checking whether the ROCE network card is changed and whether the initialization is successful;
responding to the condition that the ROCE network card is not changed and the ROCE network card is successfully initialized, polling a connection event of a network port and detecting whether the network port of the ROCE network card is newly connected or not;
responding to the new connection of the network port of the ROCE network card, applying for resources required by the new connection and judging whether the IP address of the new connection is a new IP address or not;
Responding to the new IP address of the new connection, establishing a record for the new IP address, counting the applied resources into the total number of the resources, and judging whether the total number of the resources reaches a preset threshold value;
and responding to the total number of the resources reaching a preset threshold value, sending out a corresponding warning and deleting the applied resources.
2. The method of claim 1, further comprising:
responding to the change of the ROCE network card, and detecting whether the change is a newly added network card;
and reporting the information of newly-added hardware and activating the newly-added network card in response to the fact that the newly-added network card is changed.
3. The method of claim 2, further comprising:
and reporting a warning of hardware loss in response to the fact that the change is not the newly added network card.
4. The method of claim 1, further comprising:
and reporting an initialization failure warning in response to the unsuccessful initialization of the ROCE network card.
5. The method of claim 1, further comprising:
and reading the resource limit of the ROCE network card port, and setting a preset threshold value based on the resource limit.
6. The method of claim 1, wherein the resources required for the connection include a completion queue, a queue pair, a protection domain, and a memory region.
7. The method of claim 1, further comprising:
responding to the situation that the network port of the ROCE network card has no new connection, and detecting whether the existing connection has new resource change;
in response to a new resource change for an existing connection, the corresponding change is accumulated into the corresponding IP record and into the total resource pool.
8. An apparatus for ROCE network card resource management, the apparatus comprising:
the checking module is configured to respond to system startup and check whether the ROCE network card is changed and whether initialization is successful;
the detection module is configured to poll a connection event of an internet access and detect whether the internet access of the ROCE network card has new connection or not in response to the ROCE network card not changing and the ROCE network card being successfully initialized;
the judging module is configured to respond to the situation that a new connection exists at the network port of the ROCE network card, apply for resources required by the new connection and judge whether the IP address of the new connection is a new IP address;
the statistical module is configured to respond to the fact that the newly connected IP address is a new IP address, establish a record for the new IP address, count the applied resources into the total number of the resources and judge whether the total number of the resources reaches a preset threshold value;
And the warning module is configured to send out corresponding warning and delete the applied resources in response to the total number of the resources reaching a preset threshold value.
9. A computer device, comprising:
at least one processor; and
a memory storing computer instructions executable on the processor, the instructions when executed by the processor implementing the steps of the method of any one of claims 1 to 7.
10. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 7.
