Overview & features
KDDI Global Content Accelerator is a content delivery service that uses the service of CDNetworks.
Using edge servers located in more than 80 cities and 30 countries worldwide, the service provides efficient and stable content delivery.
- * This service is provided through collaboration between CDNetworks and KDDI.
KDDI Global Content Accelerator consists of the services described below.
This service boosts website performance.
Speed is improved with advanced cache functions that deliver static (cacheable) content from the edge servers closest to the end-users. In addition, the geographically distributed network of edge servers ensures stable content delivery during unexpected traffic surges or if there is ever any trouble at a particular edge server or delivery point.
This service is the best solution for improving the performance of websites and web applications distributed across the globe. By utilizing advanced cache functions and optimizing communication protocols between content providers and their users, the performance of dynamic (non cacheable) content, two way communication, and uploads, are improved.
This service improves the performance of mission-critical applications using the TCP, such as SSL-VPN.
By utilizing a secure delivery platform with optimized communications protocols, this service boosts cost-effectiveness and performance without undermining security.
- [1] This service is available only in USA and Europe.
Cloud DNS is a highly reliable cloud-type DNS service. Reliable and scalable DNS service is provided from 23 DNS servers distributed around the world.
- China Acceleration (Optional Service)
This service supports the high-speed delivery of content to China, where web performance is relatively low. CDNetworks is the only global CDN provider that possess their own delivery platform enabling high performance in China.
Content Acceleration
Advanced cache function improves website performance
Service overview
Content Acceleration accomplishes the improvement in speed, stability and reliability of websites by delivering static (cacheable) content (images, movies, Flash, etc.) via edge servers that are geographically distributed around the world.
This service is the best solution for improving the speed of websites that deliver content over long distances, in large volumes, and those that experience high traffic loads.
Features
Speedy performance achieved by optimized routes and shorter delivery distances
Responses to static content requests are handled by the most suitable edge servers in terms of distance, server load, and other factors.
Stability and speed improved with redundancy
Content is delivered to domestic and overseas end-users via a globally distributed network of servers and delivery points.
Even under constant high-volume traffic loads or during unexpected traffic surges, the result is stable content delivery.
Better cost-effectiveness for your web platform
As much as 80 to 90 percent of static content delivery is handled by edge servers, freeing up your web servers to handle only the delivery of dynamic content, such as some of the cache misses or query processing. This reduces and balances the load in your web server environment.
Support for domestic and international content delivery
Content Acceleration supports both domestic and international content delivery. Because delivery distance is the primary cause of latency, this service is particularly beneficial to international content delivery.
Dynamic Web Acceleration
Cache functions and protocol optimization improves performance of international content delivery
Service overview
Dynamic Web Acceleration (DWA) is a service that dramatically improves the performance of websites and web applications distributed across the globe.
This service improves the delivery of dynamic content (unique pages based on particular requests by the end-user, or content that needs to be processed on your own web servers, such as product searches or user registration) for websites and web applications, and it enhances content upload performance.
With cache functions and optimized communications protocols, DWA improves the performance of dynamic content and two-way communication between the origin and the end-user. This service is ideal for improving the performance of international websites and web applications that require speed, such as those that make use of two-way communication and dynamic content.
Features
Optimized The Internet communication
The optimization of TCP and HTTP/HTTPS greatly improves web performance by minimizing packet loss and retransmission delays, and by boosting the speed of The Internet, which is a bottleneck of communication speed.
Optimized round-trip time (RTT)
Communication is performed via edge servers located closer to the end-user, reducing the frequency of access to your web servers.
This improves web performance by reducing the number of times that international communication is performed.
Advanced cache functions
Most cacheable content is processed using the Content Acceleration service's advanced cache functions. The use of cacheable content greatly reduces the frequency of access to your web servers, thereby improving web performance.
Cost-effectiveness for your web platform
Customers do not need to prepare their own dedicated web servers at overseas. In addition, because edge servers deliver static content, you can streamline the cost of maintaining your web platform.
Dynamic Network Acceleration [1]
Faster mission-critical applications
- [1] This service is available only in USA and Europe.
Service overview
Dynamic Network Acceleration (DNA) is a service that improves the performance of mission-critical applications
that make use of the Internet.
With a secure platform that incorporates technology to optimize The Internet, DNA improves the performance of applications that rely on TCP, such as SSL-VPN.
This service is ideal for organizations that make use of remote international access to mission-critical applications, such as ERP, SFA, CRM, and HR solutions.
Features
Secure communication
DNA complies with the requirements of PCI DSS, a security standard established to ensure the security of information such as credit card and transaction data. Optimizing the communication between edge servers improves the performance and reliability of applications.
TCP optimization: Connection pooling/Keepalive
TCP places a high priority on reliability, thereby reducing the efficiency of communication. However, by sustaining or reusing connections, this service minimizes the number of TCP handshakes and improves application performance.
TCP optimization: Increased window size/Data compression
There is a limit to the amount of data that can be transmitted with each packet. However, this service uses a larger segment and window size than that of standard TCP. Furthermore, the addition of data compression improves data transfer efficiency.
TCP optimization: Fast recovery
Ordinarily, when packet loss occurs due to high traffic congestion, slow-start must be performed again beginning with the minimum window size. However, this service improves transfer efficiency by quickly retransmitting packets and maintaining the largest possible window size.
Cloud DNS
DNS service offering high performance, reliability, and scalability
Service overview
DNS takes an extremely important role in the functioning of the Internet, and DNS performance directly affects the performance of a website. End-user requests are initially directed to a DNS service, which must always be available and needs to answer DNS queries reliably and correctly so that visitors can actually reach the website.
The Cloud DNS service is built on a distributed platform based in more than 30 countries around the world, ensuring a high degree of security, reliability, and scalability. Optimized routing ensures high performance, regardless of the end-user's geographical location.
Features
High performance
Name resolution is performed on DNS servers located closest to the end-user.
High performance is achieved with advanced routing technology and DNS servers distributed around the world.
Reliability
The globally distributed DNS servers minimize the risk of failure, ensures consistent availability, and provides highly reliable service.
High security
The globally distributed DNS servers provide greater protection from DDoS attacks and other cyber threats, minimizing the risk of costly outages.
Excellent scalability
The globally distributed DNS servers can support a virtually unlimited number of domains and any amount of traffic, making it easy to handle traffic increases.
