WebCache
NGAA WebCache pushes the Internet hotspot content to the operator's network, relieving hotspot content from taking up bandwidth on the backbone and interconnection.
WebCache aims at different application scenarios, divided into three major products, including: 1, Http access to accelerated HAA products; 2, mobile terminal accelerated MAA products; 3 , P2P protocol to accelerate the PAA products.
HAA System
Through the cache technology, the Internet access hotspot Web browsing, file download, video playback and other static content to speed up the rapid introduction to the operator network, effectively alleviating the backbone network and interoperability bandwidth occupied by Internet users to enhance the experience of Internet access experience.

MAA system (mobile terminal acceleration)
Relying on Cache technology, focusing on solving the mobile Internet network bandwidth is small, the user visits, hot spots repeated access, the Internet resource distribution is uneven and other reasons caused by the user access to Internet resources slow response to support through TCP and the preferred source station and other means To speed up the content of mobile Internet.
- Powerful HTML code optimization techniques and request merging techniques
- Efficient image compression and optimization techniques
- Efficient video optimization and stream adaptation technology
PAA system (P2P access acceleration)
P2P cache system, storage Internet hotspot P2P protocol-related streaming media and file downloads, etc., to guide users to access requests to the P2P Cache system, thereby reducing the customer access to the Internet delay, to solve the problem of Internet export congestion and reduce the cost of Internet export expansion.
- Support of public agreement :

- And the industry's mainstream private agreement manufacturers have a good cooperation
- Support the mainstream private protocol to crack the cache service
XCache system architecture
Through the cache technology, the Internet access hotspot Web browsing, file download, video playback and other static content to speed up the rapid introduction to the operator network, effectively alleviating the backbone network and interoperability bandwidth occupied by Internet users to enhance the experience of Internet access experience.
- Redirection system: through DNS forward and splitting DNS/HTTP redirection boot mode, users in the network are directed to the cache system for Internet access hotspots or specific content access.
- Cache system: web pages, downloads, videos, support mobile terminal acceleration, crack and drag the security chain of video websites, support TCP optimization and origin site optimization, and introduce the automatic content stripping function.
- Background support system: business discovery system, internal operation and maintenance system, monitoring and alarm system, portal display system.
Content Distribution Network XCDN Series
NGAA CDN is a new generation of content distribution platform based on edge cloud, users can rapid create personalized business systems and deploy business applications to the edge, reducing the delivery cycle for efficient and seamless connection between CDN and software.

XTV Video
XTV(IPTV/OTT) Combining CDN technology, audio/video coding and decoding technology, content distribution network technology, streaming media transmission technology and other core technologies such as source stations, build a cloud video platform. It realizes two major service modes: full terminal service (PC, Pad, Phone, STB, etc.) and full content service (live broadcast, live recording, on-demand, time shift, review, etc.). Customized development can be carried out according to the actual business needs of customers.

DNS Error correction
Background：Background: Some domestic broadband users' home routers are set to the designated DNS instead of using the LDNS automatically issued by the operator, resulting in inaccurate CDN scheduling and access errors, which not only increases the operator's inter-network settlement costs but also affects the user's online experience.
Overall logic:
- DNS error correction system is divided into error detection and implementation of the main module, log query module and Portal report to show three parts
- The main error correction system currently has a response capacity of 10 billion/day; Use big data platform to record and query logs.
- Using the Web interface to provide the overall management of the system and query; error correction system using error correction response system for users of different network DNS error correction response
- LDNS query, scheduling communication sub-module through the interaction with the LDNS to correct the basis; by monitoring the alarm and strategy to match, monitor and control the operation of the system and strategy
Log data analysis system
- Deployment purpose：
- From the third-party system perspective on the operator cache log for large data collection and analysis, analysis of the cache system business status, traffic trends and hot spots, etc.
- Overall logic:
- Content discovery system: through the DPI system, the crawler system analysis of cacheable content
- Caching System: Stores data service users and generates user access logs
- Scheduling system: through the redirection system will meet the cache rules of the user request to the system
- Presentation system: Collect logs, analyze and store, Portal display data
