Application delivery platform TongADC
Product features

  • Easy to deploy and maintain

    The product supports single arm, transparent, routing, dual machine, triangle transmission and other deployment modes. It can be configured and managed intuitively through the graphical interface of WebUI. SNMP can also be used to facilitate management. Various templates and network analysis tools are built in. It supports rich log and data statistics functions and very convenient to use, maintain and troubleshoot. 

  • Strong security

    It adopts the encryption means such as HTTPS and SSH to manage the network, and has built-in protection functions against DDoS attacks such as SYN-FLOOD, ICMP-FLOOD, UDP-FLOOD, PING FLOOD, etc., such as high-performance access control list (ACL), network address translation (NAT) and state-based packet detection means, so the network application has high security. 

  • High availability and load balancing

    Support rich L3-L7 application server load balancing to improve the availability of enterprise application and network.

  • Complete functional support

    It can achieve load balancing of local servers and links, global load balancing of multiple data centers, and load balancing of DNS and cache servers. 

  • Integrate the next generation data center

    Fully supports virtualization technology, including virtualization operating system based on server running environment, which can make more efficient use of system resources. At the same time, it can provide management functions based on the role and virtualization. 

  • Strong processing power

    The system adopts multi-core technology and original super parallel processing architecture, which makes the processing performance of L4-L7 greatly improved. Combined with various application optimization technologies: TCP connection multiplexing, HTTP compression, fast caching and SSL acceleration, significantly improved the user experience. 

Product functions

Security protection

Supports anti DDoS attack, connection speed limit and flow control, IP anomaly detection, DNS application firewall and mail security processing, and supports system security protection. 

Application optimization and acceleration

Through TCP connection multiplexing, content caching, HTTP caching, SSL acceleration and other functions, the comprehensive acceleration and application optimization can be achieved. 

Link load balancing

It can solve the problem of traffic sharing under multi link, provide the best solution for users' multi link network application, solve the problems of North-South telecommunication interconnection, link redundancy, link intelligent switching, link load, speed up traffic processing speed and improve service response speed. 

Global server load balancing

According to the policy, users' requests can be distributed to the sites providing the same service, so as to achieve the traffic balance among multiple sites. 

Comprehensive load balancing technology

Support L4-L7 server load balancing, including TCP, UDP, HTTP, HTTPS, FTP, SMTP, SIP, SMTP and other dozens of protocols, including VoIP and streaming media, mail security, network security, authentication and billing, remote disaster recovery, content caching and other specific applications. 

Multiple session persistence technologies

Provides support for session persistence based on source IP address, Cookie, destination IP or SSL ID. 

Advanced health examination technology

All kinds of applications and servers can be detected to ensure the reliability of all applications and equipment. The existing or customized health check strategies can be used to monitor the health status of the server and its application to ensure that the failure of a single application service will not affect the access.

Rich application load balancing algorithm

Supports rich load balancing algorithm, use VIP (virtual IP) to connect with multiple real services

According to the performance and health status of the real server, it selects the best server to respond to the user's application request, and provides more than ten kinds of flexible load balancing algorithms, such as polling, weighted polling, minimum connection, weighted minimum connection, priority, minimum response time, IP address hash, URL hash, etc. 

Product architecture

Tongadc adopts multi-core CPU and integrates advanced software and hardware technology to achieve the perfect combination of rich functions and high performance.

SPOS is a self-developed operating system, which makes full use of the advantages of multi-core CPU in application traffic processing. It can optimize the data packets running on each L4-L7 multi CPU, realize the dynamic and robust allocation and processing of application traffic among multiple CPUs, no locking, memory contention and copy slowness among multiple CPUs, which allows optimizing the L4-L7 protocol and service management in real time. 


The system adopted original multi CPU parallel supercomputing architecture, combined with rich 2-3 layer network functions and 4-7 layer optimization acceleration technology, which can use custom scripts to process 4-7 layer application traffic, so as to accelerate and expand all applications and ensure application security. By balancing packet allocation to high-performance CPU and high-speed memory, SPOS can avoid the performance bottleneck problem caused by overload of one or more CPU cores, which makes the system perform strongly. When multiple functions are enabled at the same time, the performance of the device will not be significantly reduced.
