Description
Technical Field
The application relates to communication equipment, in particular to a message sending method and equipment.
Background
When the intelligent lossless network of the data center is based on a RoCEv2 (RDMA over Converged Ethernet Version 2, second-generation remote direct memory access is carried on the Ethernet), the intelligent lossless algorithm integrating PFC (Priority-based Flow Control ) and other technologies can realize packet loss-free, low-delay and high-throughput flow transmission on the Ethernet, meet the requirements of a storage system and realize the integration of calculation and storage networks.
However, in order to store a large amount of data, a storage system often needs to manage a huge number of hosts, and there are cases where new hosts sequentially access network devices. In order to make the intelligent lossless network technology better serve the storage system, an iNOF (Intelligent Lossless NVMe Over Fabric, intelligent lossless storage network) technology is provided, a newly accessed host can be known at the first time through quick control of the accessed host, relevant configuration of the intelligent lossless network is intelligently adjusted, and the iNOF technology supports the notification of host information to the storage system, so that the storage system can be assisted in managing the host.
In the iNOF composition, the switch is used as a network core to realize the IP service domain management function, manage the access equipment information, monitor the network state, and realize the synchronization of the IP (Internet Protocol ) service domain and the equipment state information between the switches in the network, thereby timely notifying the nodes subscribing the change of the network equipment state information in the IP service domain. When the host is used as a storage service user and accesses the network, the host sends equipment access information and periodically announces, subscribes to the network state change information, and receives and processes the network change information. And when the device is stored as a service provider and accessed to the network, sending device access information and periodically notifying. The message interaction process in the enof network is shown in fig. 1.
In a practical application scenario, the format definition of the host/stored state notification message of the iroftechnique is inconsistent with the format of the state notification message in the ODCC standard. When the state of the host/storage in the irif network changes, the switch will send a state change notification message to the host/storage in the domain, and the existing switch mostly implements the state notification message according to the ODCC (Open Data Center Committee open data center committee) standard, where the 4-byte device state field is different from the 1-byte device state field of the host/storage using SNSD open source software, which will cause the host/storage not to reply to the ACK message. It becomes important to solve the problem that the switch is compatible with the open source software message format standard of ODCC and SNSD.

FIG. 3 is a flowchart of a method for sending status notification messages compatible with different formats provided in the present application; the embodiment is applied to the switch equipment of the INOF network, and comprises the following steps:
step 301, enabling an intelligent lossless storage network function;
step 302, receiving an LLDP message;
in the application, in a reserved field of an LLDP notification message sent by a host/storage, a high 2 bit field of a 1 st byte is a device status byte length flag bit; the bit 01 of the flag bit indicates the length of a device state field in a state message which can be identified by the current support SNSD of the host/storage, namely the device state field in the state message sent by the opposite terminal is 1 byte; the flag bit 00 indicates that the length of the device status field byte in the state message of the host/storage supporting ODCC standard, i.e. the device status field in the opposite end sending state message is 4 bytes.
Step 303, judging whether to enable the forced compatibility standard OCDC standard function; if yes, go to step 304; if not, go to step 305;
step 304, ignoring the device status byte length flag bit in the check LLDP message;
in the application, after the switch enables the iroffeature, the network administrator can remotely or locally configure the switch to force the function compatible with the ODCC standard. The switch enables the standard OCDC standard function in the forced establishment, receives the LLDP message sent by the host/storage device, and ignores the device status byte length flag bit in the LLDP message.
Step 305, sending a status notification message with a byte length of 4 bytes for the status field of the device;
in a status notification message sent by the switch to the peer (host/storage device), the length of the device status field is 4 bytes.
Step 306, checking whether the device status byte length flag in the LLDP message is 01; if yes, go to step 307, if no, jump to step 305;
in the present application, if the switch does not enable the function of forcing compatibility with the ODCC standard, it will check whether the device status byte length flag bit in the reserved field T-L-V of the LLDP message is 01. If the device status byte length flag bit in the reserved field T-L-V of the LLDP message is 01, the byte length of the device status field is 1 byte in a status notification message which is required to be sent to a host/storage device at the opposite end; if the device status byte length flag bit in the reserved field T-L-V of the LLDP message is 00, it is 01. If the device status byte length flag bit in the reserved field T-L-V of the LLDP message is 01, the byte length of the device status field is 4 bytes in the status notification message to be sent to the host/storage device at the opposite end.
Step 307, send a status notification message with a byte length of 1 byte for the device status field.
The embodiment shown in fig. 3 has the beneficial effects of effectively solving the problem that the switch in the actual application scene of the iNOF is compatible with the SNSD open source software and the ODCC standard protocol format, so as to ensure the normal operation and maintenance of the iNOF network.
