Data Center Fast CNP Congestion Notification Technology White Paper 1 Background In data center and high-performance network environments, network congestion is a critical issue affecting data transmission efficiency and service quality.As shown in the figure below, traditional congestion control mechanisms require network devices to detect congestion, mark the ECN field in packets, and forward them to the traffic receiver. After receiving the marked packets, the receiver sends a CNP(Congestion Notification Packet)[1] to the traffic sender through upper-layer protocols (such as...

IPT (In-band Path Telemetry) Technology Whitepaper: Network Quality Monitoring for AI Data Centers 1 Overview With the rapid development of high-performance applications such as AI large model training and distributed computing, AI computing networks face increasingly stringent requirements for end-to-end path quality monitoring. Traditional network monitoring technologies (such as SNMP) are limited by their “pull-only” collection mode and insufficient granularity, making them inadequate for monitoring micro-burst anomalies in network-wide path latency and packet loss. INT...

INT Technology: Buffer Drop Capture (BDC) and High Delay Capture (HDC) 1 Overview With the rapid development of high-performance applications such as AI large model training and distributed computing, AI computing networks face increasingly stringent requirements for real-time performance and stability. Issues such as network latency and buffer overflow directly impact training efficiency and model accuracy. Traditional monitoring technologies (e.g., SNMP) struggle to meet complex scenario demands due to limitations such as low collection precision and insufficient granularity. INT...

NETCONF XML Management Protocol 1 Overview Traditional network device configuration management methods, such as CLI (Command Line Interface) and SNMP (Simple Network Management Protocol), have various limitations in handling complex network environments. To address these challenges, the IETF standardized NETCONF (Network Configuration Protocol) based on RFC 3535. NETCONF is a network configuration management protocol defined by IETF RFC standards, designed to replace SNMP. It provides a standardized mechanism for installing, manipulating, and deleting network device configurations,...

Data Center Bridging Exchange Protocol Technology 1 Overview DCBX (Data Center Bridging Exchange) is a protocol defined by IEEE 802.1Qaz standard. DCBX uses LLDP (Link Layer Discovery Protocol) as the transport mechanism to enable automatic negotiation and configuration of DCB (Data Center Bridging) features between network devices, thereby achieving lossless Ethernet transmission and enhanced QoS (Quality of Service) capabilities. 1.1 Functional Scenarios DCBX protocol is a key enabling technology for implementing data center network automation. In data center network convergence...

Power over Ethernet (PoE) for CX-M Campus Switches: Capabilities and Configuration Guide 1 Introduction PoE (Power over Ethernet) is a technology that provides electrical power to network devices through network cables. PoE technology can transmit power and data signals simultaneously, eliminating the need for additional power cables. The principle of PoE technology is to add DC power to Ethernet cables, allowing network devices to receive power directly through network cables. PSE (Power Sourcing Equipment): PSE devices are network equipment that support PoE technology and...
