Softswitch actual product development , the same protocol stack often been used in different products , the products for specific applications in different environments , leading to the requirements of the protocol is not the same . Although the protocol stack are many commonalities , but for different products with different solutions based on the same protocol led to the same commercial code, the difference is increasing. A lot of human and financial resources wasted in duplication of effort , and the solution can not be a good accumulation and sharing. More serious is now common protocol devices often requires several parts, but combine them often brings conflict of the common parts of each agreement . Now the system has brought a large capacity requirements of distributed demand , high-reliability redundant bring demand and bring practical and easy management needs , but also because there is no unified program and has been unable to effectively resolved. In order to solve the current problems faced by softswitch equipment , this paper presents a common protocol platform solution , the program meets the soft switching equipment functional requirements , maintainability requirements , scalability requirements , high availability requirements and flexibility deployments. Based on the proposed unified protocol architecture , protocol stack layers can be developed independently , in the same operating environment, and for the system management module , each protocol layer is a separate module , thus either a protocol layer on the overall architecture are able to maintain the same shape , to facilitate the development of a protocol layer . This paper extends the Trillium layer management functions, using the master agent and subagent hierarchical network structure, management data can be directly distributed to various target entity , thereby eliminating the configuration of the coupling between the various modules , making the system has good scalability and maintainability. This paper presents a dual plane DFT / HA architecture , a common protocol nodes are divided into the main plane and the backup plane , the main plane node traffic load sharing and data processing , the backup node plane as the main plane of the standby node , with the main plane nodes form 2 * N mode of operation , improve the system's switching speed and switching reliability. Finally, this paper through the use of pre-paid business model, the common protocol platform solutions were tested to achieve results , and gives the test results.
