A generic routing platform in cloud computing environment

Cloud computing has greatly expanded the range and scope of IT services, serving as a link between cloud computing service providers and consumers, and the pan-routing platform provides high-speed, reliable, scalable, and Easy-to-use wide-area data transfer platforms for cloud computing. This paper discusses the architecture and characteristics of the future development of the pan-linked routing platform.

The characteristics of the generic routing platform

Cloud computing mainly includes public cloud and private cloud, cloud computing center is connected with end users through wide area data transmission platform, providing cloud service for public users or enterprise internal users. Because of the large number of terminal users using cloud services, the wide distribution and the variety of access modes, the data transmission platform hosting cloud computing is called a generic routing platform. As shown in Figure 1:

Fig. 1 schematic diagram of a generic routing platform

Although the type of cloud service provided by the public cloud and the private cloud is different from the object, the network connection mode and the architecture model are different, but from the characteristics of cloud computing itself, the generic routing platform hosting cloud computing services has some common characteristics:

High availability: To ensure the high availability of cloud computing services, in addition to the high reliability of the cloud computing Center, the generic routing platform must ensure the high reliability of the network access Service, the network connection "forever online", so that cloud computing for the end users to provide the most reliable and safest data storage center to provide a guarantee problem. ；

Easy to use: the pan-link routing platform must be compatible with a variety of terminals, multiple access methods, so that more users to use cloud computing services, maximize the scope of the expansion of cloud computing services, will be the user terminal equipment requirements to minimize, use to simplify, so that users can through "any terminal, any location, any way" Access to cloud computing services;

Scalable: With the development of cloud computing, the pan-link routing platform must be scalable, accessible to new cloud computing centers, new user terminals, and fast service delivery.

Ii. the framework of the pan-linked routing platform

The generic routing platform needs to organize the network architecture according to the public cloud, the private cloud traffic model, and to meet the high availability, ease of use and scalability of the cloud Computing data Center to the end-user service through the access and business processing capability of the routing devices at all levels.

1. Public cloud generic Routing platform architecture

The public cloud is targeted at users, who connect to cloud computing centers via Internet access. Therefore, the public cloud-linked routing platform is for all Internet users, providing large capacity, fast, high availability, secure Internet access platform. Its platform architecture is shown in Figure 2:

Figure 2 Public cloud generic routing platform architecture for all Internet users

Public cloud is usually large, with 2 or more data centers, with a number of high-speed Internet exports, its pan-routing platform is mainly composed of core-level routers, external layer routers:

Core Layer Router: Connect cloud computing Data center with Internet exit, perform high-speed data forwarding;

Outer layer Router: Connect the operators ' Internet outlets, perform bulk routing and session processing.

The main features of the public cloud-associated routing platform are:

Full-network routing processing: The outer-layer router and the operator's high-speed Internet connection, and with the operator Internet full network routing (about 17~20 million), conducive to improving the speed of Internet access, the implementation of more efficient flow streaming and load strategy;

High-speed convergence: The trans-link routing platform must have the reliability of the telecommunication level, and can complete the seamless switching in connection fault, equipment failure, internet routing convergence and so on, ensure the cloud computing service is uninterrupted;

Routing cascade: The core layer of multiple cloud computing data centers is routed through a dedicated line cascade to enable high-speed data exchange and backup in multiple data centers through a flexible and scalable distributed architecture, providing a more high-performance and reliable cloud computing service.
