Multiple Network Acceleration employs multi-channel network aggregation technology to bundle multiple network links and treat them as a single large logical network channel. It also supports cross-ISP acceleration and backbone network acceleration. The network topology is shown in the figure below：
Mobile Network Multiple Network Acceleration
Improve network bandwidth and speed: Multi-channel network aggregation enables data transmission over multiple network paths, increasing overall bandwidth and speed. This allows users to access online services more smoothly and quickly, significantly improving the user experience.
Provide higher network reliability and stability: Since multi-channel network aggregation binds multiple network lines, when a certain channel is interrupted or fails during transmission, the system will automatically switch to another channel, effectively avoiding large-scale network interruptions or downtime.
Improve application stability and reliability: Multi-channel network aggregation can balance application load, scatter applications across multiple network channels for transmission, and perform automatic correction of transmission errors, thereby improving application stability and reliability and reducing issues like application lag, crashes, or restarts caused by connecting line problems.
Reduce O&M costs: Network operators can seamlessly deploy network infrastructure through multi-channel network aggregation. By bundling multiple network lines into one large network channel, operators gain greater flexibility in bandwidth allocation, improve network operation efficiency, and reduce the time and cost associated with online deployment and network maintenance.
Mobile phones and various industry terminals can be equipped with this product service, simultaneously using multi-operator cellular networks, Wi-Fi networks, or satellite network internet access. It intelligently aggregates and switches networks to guarantee user network quality in production and daily scenarios, with broad applicability for online games, online meetings, industrial inspection, video-on-demand, live stream, remote control, and autonomous driving.
Cross-Carrier Network Acceleration
In scenarios where the client access network and the origin server are on different networks (for example, a China Mobile home broadband user accessing an origin server deployed in a China Unicom IDC), the access traffic must be relayed through nationwide interconnection nodes or Internet Exchange Points (IXPs).
Traversing nationwide interconnection nodes or Internet Exchange Points (IXPs) may increase latency due to physical detours.
Bandwidth limitation: Some interconnection nodes or Internet Exchange Points (IXPs) may experience bandwidth bottlenecks. This can cause packet queuing, especially during traffic surges, leading to increased latency and packet loss, particularly during evening peak hours.
Cross-network access negatively impacts actual business operations by causing service access stutter, which severely degrades service access quality.
Poor cross-network access quality may cause customers to migrate to the origin server, leading to significant customer churn.
Multi-Network Aggregation Acceleration (Tencent Cloud Jutong) accelerates traffic only to the target origin server. It achieves this through a lightweight acceleration APP (Windows/Android/iOS) on the client side, which requires simple configuration:
Accelerated traffic is routed to the nearest distributed acceleration gateway (deployed across 18 points nationwide) to avoid detours.
The acceleration gateway accesses and egresses traffic on the same network. This avoids network latency jitter and packet loss caused by peak-hour congestion at Internet Exchange Points (IXPs).
Backbone Network Acceleration
When data leaves the "mobile network acceleration" phase and enters the wide-area transmission stage, backbone network acceleration becomes critical. The "aggregation gateway" (deployable on Tencent Cloud, third-party clouds, or self-owned IDCs) uses "global ultra-low-delay transmission dedicated lines" to further forward cross-network integrated traffic at high speed to business servers. These dedicated lines typically feature large bandwidth, high QoS assurance, and low jitter, creating prioritized channels for business traffic at the ISP backbone network level. They drastically reduce delay and packet loss in cross-region and cross-border transmission, underwriting the experience of latency-sensitive services such as IoV real-time control, industry remote operations, and high-definition video conferences.
Acceleration Principle
Multiple Network Acceleration is essentially a "multiplexing tunnel technology". It addresses mobile network access issues in various scenarios by reusing multiple physical links.
Terminal (client)
The deliverable is a cross-platform SDK (Android / iOS / Linux).
Key hardware must have multiple network interfaces (Wi-Fi/cellular/Ethernet, even satellite).
The SDK intercepts accelerated traffic at the terminal. Based on different Business Network requirements, it encapsulates the original message into tunnel packets and dynamically allocates them across multiple physical links.
Aggregation Gateway (server-side)
Aggregation Gateway is a server network element. It terminates tunnel traffic and restores it to original business traffic.
The aggregation gateway has different delivery modes (described later) based on deployment location (Tencent Cloud/third-party cloud/customer IDC).
The aggregation gateway acts as NAT and routes business traffic back to the origin via public network, dedicated line, or private network.
Acceleration mode
Acceleration mode: Different businesses have different network requirements. Some hope for "low latency", some for "deterministic performance", and some require "large bandwidth". To meet these different network requirements, Tencent Cloud Jutong implements different algorithms. It distributes data packets across each physical link with different policies and speeds.
Global Acceleration Network
It refers to a global ultra-low-delay transmission network for backbone segments, achieving a highly reliable data transmission network worldwide.
