Analysis: VLAN solution: For high-speed computing networks, different VLAN+ACLs are used to achieve inter-tenant isolation to meet the security requirements of multi-tenant isolation.

Analysis: The headroom cache space occupies the shared cache of the inbound queue, because the cache of the queue is allocated by the port cache, and the cache of the port is allocated by the plane cache, so only when the plane cache is sufficient, can the sufficient headroom be guaranteed Cache space to ensure lossless packet forwarding of lossless queues. The Ranging Headroom check function allows you to calculate the amount of cache space you need based on the configured port long-haul mode (i.e., link distance) and port rate.

Parsing: iNOF packets are TCP-encapsulated packets with TCP port numbers ranging from 10000 to 57999 and 19516 by default , which contains key iNOF information in the Data field of TCP packets. The client can send key iNOF information to the reflector through the iNOF packet, and the reflector summarizes it and then sends it to other clients. Through iNOF messages

The following types of information can be transmitted: Connection information: ▫ The iNOF reflector and the client need to exchange iNOF packets to establish an iNOF connection, similar to TCP connection. ▫ Domain configuration information: In the iNOF system, the device can manage the connected host through the zone, and after the iNOF domain configuration is completed on the iNOF reflector, it will pass through the iNOF The packet sends the domain configuration information to each client. ▫ Host dynamic information: When a new host connects to the client or leaves the client, the host will actively send LLDP packets to the client, and the LLDP will be recorded in the packet The change of neighbor information allows other devices in the iNOF system to perceive the host dynamic information. ▫ Interface Error-Down Information: Interface Error-Down is triggered when the iNOF device is triggered due to a PFC deadlock or a CRC error packet that reaches the alarm threshold After that, the iNOF packet will carry the interface Error-Down information, so that other devices in the iNOF system can quickly sense it and adjust the path information in time. •After the iNOF system is established, all devices in the system can perceive the changes of the access host at the first time, so that the information can be fed back to each intelligent lossless network function, and the relevant configuration can be intelligently adjusted, so that the network can finally achieve low latency, no packet loss, and high throughput performance.
