一、Physical distance and network routing are fundamental factors. Data is transmitted back and forth between users and servers, and the farther the distance, the higher the basic latency. The actual network transmission still needs to go through multiple routing nodes, and if the routing planning is poor, the delay will further increase.

International bandwidth and network congestion are also key factors. China's Internet export bandwidth is limited. During the peak access period, a large amount of data crowd the export bandwidth, which is easy to cause congestion, leading to increased latency and even packet loss.

Server performance and configuration are equally important. If the hardware configuration of the overseas server itself is insufficient, it will be difficult to handle a large number of concurrent requests, which will lead to slower response times. The size of the export bandwidth directly determines the speed of data transmission, and small or shared bandwidth is prone to bottlenecks during peak traffic periods.

The efficiency of transmission protocols can also affect access speed. The traditional TCP protocol experiences significant performance degradation when encountering high latency or packet loss. Unoptimized HTTP requests, such as those without compression enabled or multiple small file requests, can also increase unnecessary transmission overhead.

Network layer optimization, selecting high-quality lines and architectures

Optimizing the network layer is the most direct and effective way to improve access speed, with the core being to reduce latency and avoid congestion.

Choosing high-quality network connections is a fundamental but crucial step. When selecting servers, priority should be given to data centers that provide CN2 GIA (Global Internet Access) lines. This is a high-quality network of China Telecom, which is directly connected to Chinese Mainland with low latency, low packet loss rate and high stability.

Deploying CDN (Content Delivery Network) is a highly effective solution. CDN caches the static resources of a website to edge nodes around the world, allowing users to obtain content from the geographically nearest nodes, greatly reducing the loading time of static resources.

For websites with a lot of static content, such as news, blogs, and e-commerce, the effect is particularly evident. It should be noted that traditional CDN has limited acceleration effect on dynamic content.

Building an efficient network architecture can further enhance performance. For enterprises with multiple overseas nodes, BGP multi line access can be used to automatically select the optimal path for users of different domestic operators, solving the problem of cross operator access.

A more advanced solution is to use SD-WAN (Software Defined Wide Area Network), which can monitor the quality of multiple network links in real time and intelligently allocate data flows based on preset policies to ensure the smoothness of critical business operations.

Upgrading server configuration and bandwidth is a fundamental guarantee. Ensure that the server hardware resources (CPU, memory) are sufficient to quickly process requests. Upgrading shared bandwidth to exclusive bandwidth can effectively avoid network speed drops caused by resource competition during peak hours.

Enabling modern network protocols can significantly improve transmission efficiency. Enable HTTP/2 or HTTP/3 (QUIC) protocol on the server. HTTP/2 supports multiplexing, allowing multiple requests to be sent over a single connection, reducing the overhead of establishing multiple TCP connections.

HTTP/3 is based on UDP, further reducing the latency during connection establishment and maintaining good performance even in poor network conditions. Adjusting the TCP congestion control algorithm to BBR can intelligently cope with network congestion and increase throughput by 15% -20% in cross ocean links.

Implementing data compression can reduce transmission volume. Enabling GZIP or Brotli compression on the server side can effectively reduce the transmission volume of text resources (HTML, CSS, JS), typically reducing data volume by 30% -70% and speeding up loading speed.

Application layer optimization cannot be ignored either. Optimizing website content and code, compressing and optimizing images (using WebP format), merging CSS and JavaScript files, and removing redundant code can all effectively reduce the amount of data transmitted.

04 Azure Specific Optimization Solution, Utilizing Platform Features

The Azure platform provides a range of unique features to optimize access speed, and utilizing these features effectively can significantly enhance the user experience.

Use Adjacent Placement Groups (PPG) to reduce latency. When deploying applications in Azure, network latency can be created by distributing virtual machine instances across regions or availability zones, which may affect application performance.

Adjacent placement group is a logical grouping used to ensure that the physical locations of Azure computing resources are close to each other. For applications that require low latency, such as games, engineering simulations, and high-frequency trading, neighboring placement groups can be considered for the node pool of the cluster.

Optimizing FHIR routing can improve network paths. When there are multiple FHIR lines, they can be connected to Microsoft through multiple paths. The result is that the routing used may not be the most ideal - the longer the network path, the more severe the delay.

By implementing the 'local preference' attribute, it can be ensured that traffic sent to Azure through FHIR traverses the optimal path.

Implement Quality of Service (QoS) policies to prioritize handling critical traffic. By utilizing QoS in Azure Virtual Desktop, real-time RDP traffic that is sensitive to network latency can take priority over less sensitive traffic.

QoS uses Windows Group Policy Objects to identify and label all packets in real-time streams, helping the network allocate a portion of dedicated bandwidth for RDP traffic.
