1. The IPTV (television TV, Unicom TV, etc.) standard system has been further improved
With the country’s release of relevant documents for the comprehensive promotion of “triple play†and the continuous improvement of policy controls on Internet TV and other services, product intelligence upgrades and service expansion in IPTV service systems have become a trend for telecom operators to drive broadband networks and promote digitalization. The core mission of establishing an operating system.
The recent meeting of the China Communications Standards Association IP and Multimedia Communications Technology Working Group IP Business and Applications Working Group (WG2) reviewed the technical requirements for the telepresence videoconferencing system protocol - Part 3: Media transmission, multi-screen interaction - Based on local Inter-terminal interactive technical requirements of the network, Smart TV--Technical requirements and test methods for network access, etc. Three drafts of the communications industry standards for review, discusses the collection and analysis methods of IPTV terminal-side service quality parameters and IPTV user data analysis and recommendation platform. Two draft specifications for technical specifications, two testing methods for intelligent voice interaction technologies, and two technical requirements for smart TVs.
The WG2 meeting determined that in 2016, the latest technical development results in the current “triple play†field will be combined to further refine and revise the IPTV standard system to meet the needs of domestic related business development in the new era.
2. In addition, CDN (Content Delivery Network) series of standards have also been further improved
The China Communications Standards Institute IP and Multimedia Communications Technology Working Party Source Code Coding Working Group (WG3) reviewed and approved the drafting of the metadata framework for policy-based content distribution network. The relevant background is as follows:
With the continuous development of Internet networks and applications, it is becoming more and more important to use the network for storing, searching, and using digital information. At the same time, the service provider provides information content processed by using different coding technologies in order to adapt to the use of various terminal information retrieval services. Therefore, user metadata is required to support the provision of services with adaptive functions.
Making full use of network metadata to provide users with media services adapted to different networks, different terminals, personalization, and high service quality is a hot topic currently researched and developed by service providers and network providers.
After thorough deliberation, the participating experts considered that the formulation of the standard is very necessary, and that the specified metadata framework can be applied to all kinds of content distribution, not just the content distribution network. It is recommended that the name of the standard be modified to be metadata for content distribution. frame.
In addition, WG3 and WG2 jointly discussed the relevant industry standards for content delivery network technology requirements, covering “application scenarios and requirements for content delivery network technology requirementsâ€, “functional network architecture for content delivery network requirementsâ€, and “content delivery network technology requirements for content routingâ€. , "Content delivery network technology requirements edge service node" and so on.
3. In addition, the open data standards for big data, telecommunication and internet industry are discussed
The China Communications Standards Association IP and Multimedia Communication Technology Working Committee New Technology and International Standards Working Group (WG4) discussed 2 drafts, 11 drafts of drafts, 2 drafts submitted, and 25 new proposals.
Which involves the future network (SDN - software-defined network), data center, big data, cloud computing, data open and other technical fields.
The review passed the technical requirements for the server management subsystem of the entire rack and the cloud distribution technology requirements based on the CDN (Content Delivery Network).
It also discusses the transfer of 7 research topics including pre-made power module technical requirements for data center infrastructure and virtualized software testing requirements of cloud computing servers to the review drafts for the two communications industry standard consultation papers and reconfigurable data networks. As a standard project of China Communications Standards Association Association.
In addition, 20 proposals and 3 research projects were approved. The project proposal contains 15 aspects of basic data platform testing for big data, openness of telecommunication and Internet industry data, and so on, indicating that the standardization of big data has been fully implemented in the association.
4. Partial research results based on the FDN (Future Data Network) series of standards
The China Communications Standards Association IP and Multimedia Communications Technology Working Committee's Future Data Network (FDN) Working Group (SWG3) discussed six FDN domain standard manuscripts and one new project proposal.
Final review of the review of technical requirements for network service chains based on FDN, reviewing the technical requirements for deep packet inspection equipment based on FDN and the FDN-based network model and the technical requirements for northbound interface requirements The technical requirements of the business chain are recommended by the project.
The rapid growth of current Internet traffic has become a major bottleneck for network development. Network service providers urgently need sophisticated traffic management capabilities, and content-aware systems with DPI capabilities at their core as capacity providers are the basis for traffic management.
The current content-aware system is implemented independently by each manufacturer, lacks interoperability and openness, and there is no uniform standard to regulate internal implementation and evaluate device-sensing effects. In the existing network applications, problems such as the inability to uniformly perceive the results and meet the scalability requirements for scale deployment have arisen.
Against this backdrop, the technical requirements for deep packet inspection equipment based on FDN are one of a series of standards for future data networks. The series of standards also plans to include "FDN application scenarios and requirements", "FDN architecture", and "FDN communication protocol". "Wait.
The industry standard aims to use software-defined network and network functions to virtualize data processing and forwarding ideas, and feature modules such as feature-aware system feature management, device control, analysis and recognition, and image forwarding are standardized in a standard form and unified interface. The centralization and standardization of perception enhances the flexibility and scalability of device deployment and awareness policies, and provides a unified and reusable data source for various upper-layer capabilities related to traffic management.
Through the analysis of the technical requirements of the content-aware system in this standard, the overall requirements for future content-aware systems based on new technologies such as software-defined networks and network function virtualization are summarized.
