摘要： A method for determining metrics of a content delivery and global traffic management network provides service metric probes that determine the service availability and metric measurements of types of services provided by a content delivery machine. Latency probes are also provided for determining the latency of various servers within a network. Service metric probes consult a configuration file containing each DNS name in its area and the set of services. Each server in the network has a metric test associated with each service supported by the server which the service metric probes periodically performs metric tests on and records the metric test results which are periodically sent to all of the DNS servers in the network. DNS servers use the test result updates to determine the best server to return for a given DNS name. The latency probe calculates the latency from its location to a client's location using the round trip time for sending a packet to the client to obtain the latency value for that client. The latency probe updates the DNS servers with the clients' latency data. The DNS server uses the latency test data updates to determine the closest server to a client.

摘要： A dynamic image delivery system receives a client request for an image at an image caching server. The image caching server measures the client's network access speed and looks for an appropriate pre-rendered copy of the requested image that is rendered for the client's network access speed in local storage. If the appropriate rendered copy is found, then the image caching server sends the rendered image to the client. If it is not found, then the image caching server dynamically renders a copy of the image and sends it to the client.
摘要翻译： 动态图像传送系统在图像缓存服务器处接收对图像的客户端请求。 图像缓存服务器测量客户端的网络访问速度，并查找为本地存储中的客户端网络访问速度呈现的请求映像的适当预呈现副本。 如果找到适当的渲染副本，则图像缓存服务器将呈现的映像发送到客户端。 如果没有找到，则图像缓存服务器会动态呈现图像的副本并将其发送给客户端。

摘要： A method and apparatus for serving content requests using global and local load balancing techniques is provided. Web site content is cached using two or more point of presences (POPs), wherein each POP has at least one DNS server. Each DNS server is associated with the same anycast IP address. A domain name resolution request is transmitted to the POP in closest network proximity for resolution based on the anycast IP address. Once the domain name resolution request is received at a particular POP, local load balancing techniques are performed to dynamically select the appropriate Web server at the POP for use in resolving the domain name resolution request. Approaches are described for handling bursts of traffic at a particular POP, security, and recovering from the failure of various components of the system.

摘要： A distributed DNS network includes a central origin server that actually controls the zone, and edge DNS cache servers configured to cache the DNS content of the origin server. The edge DNS cache servers are published as the authoritative servers for customer domains instead of the origin server. When a request for a DNS record results in a cache miss, the edge DNS cache servers get the information from the origin server and cache it for use in response to future requests. Multiple edge DNS cache servers can be deployed at multiple locations. Since an unlimited number of edge DNS cache servers can be deployed, the system is highly scalable. The disclosed techniques protect against DoS attacks, as DNS requests are not made to the origin server directly.

摘要： A network of point of presence servers allows a customer to organize their web site by functions where functions are mapped into domain names. The functions have requirements that define what is needed by a server to satisfy the function. The domain names are mapped into resources or servers that can be addressed by the domain name and that satisfy requests for the function that domain name has been defined to support. This method of organization allows individual elements of a web page to be retrieved from different resources and gives the name server the control to direct users to an available and optimal server for a given resource.
