On August 11, Tencent Cloud announced a major upgrade of the VPC (Virtual Private Cloud, cloud private network) architecture. The new architecture adopts a number of Tencent's core self-developed technologies, which can support users to build the industry's largest ultra-large-scale single VPC network with 3 million nodes, and maximize the forwarding performance to an industry-leading 200Gbps. At the same time, Tencent Cloud VPC is also the first in the industry to realize millisecond-level network fault perception and has fast self-healing capabilities.
VPC is a network space dedicated to users on the cloud. In this private environment, users can freely manage and configure the network, including IP addresses, routing rules, etc. At present, VPC is widely used in scenarios such as building large-traffic video, live broadcast services, Internet of Things services, game acceleration services, and hybrid cloud construction.
At present, with the acceleration and deepening of the "cloudization" process of enterprises, more stringent requirements are put forward for the scale, performance and stability of VPC in scenarios such as comprehensive cloud native, cloud-edge integration, and high-performance computing.
Tencent Cloud's newly upgraded VPC architecture effectively solves these challenges by applying a number of self-developed technologies such as HARP network transmission protocol, Yinshan DPU system, and software-defined routing access system.
Among them, Tencent Cloud's self-developed software-defined routing access system innovatively uses "controller delivery technology based on separation of cold and hot data", etc., which can support users to build the industry's largest 3 million node single node under the premise of ensuring overall performance. VPC greatly reduces the complexity of multi-VPC management and O&M. It is worth mentioning that this set of core technologies has won the Top Ten Future Leading Science and Technology Innovation Achievement Awards in China's communications field.
Through the self-developed high-performance DPU chip and software-hardware collaborative architecture, Tencent Cloud realizes network forwarding with a packet rate of 50 million pps, bandwidth of 200 Gbps, and low-latency forwarding of less than 10 microseconds under the session specification of over ten million levels. leading.
In addition, Tencent Cloud's self-developed network protocol HARP, using multi-path adaptive transmission strategies and self-developed congestion control algorithms, can realize millisecond-level perception of physical network failures and congestion, and automatically block abnormal paths. Even in extreme scenarios such as abnormal switch failures and fiber cuts, Tencent Cloud VPC can intelligently process cloud network traffic scheduling to ensure that user services are not affected, and the availability of virtual networks is higher than that of physical networks.
Chen Kang, deputy general manager of Tencent Cloud Network Product Center, said that continuous breakthroughs in self-developed core technologies are rapidly driving the comprehensive upgrade of Tencent Cloud's VPC service capabilities, and the new generation of VPC will provide a strong boost to the business expansion of enterprise customers.
Statistics show that Tencent Cloud VPC has gone through several generations of evolution since its birth, and has now served millions of enterprise customers.
