Definitions

• PID Partition ID: This is merely a mapping of IP prefixes at the AS level to integers. This is a one-to-one mapping. This is a very coarse partitioning of IP prefixes.
• LRU Least Recently Used It is an example of replacement algorithm or a replacement policy. LRU discards the least recently used items first. Often used to pre- place caches, in this invention, it is used this to replace files on a disk.
• the CDN manager hosts the Content Manager API, the DNS API and the Network Topology API (all APIs are on this server). There is one instance of the CDN manager for the entire CDN.
• the CDN manager may reside at one of the publishing points or in a separate server.
• the CDN manager may reside in OB0 or any one of the OBs.
• Tracker The tracker is the key entity that enables intelligence and coordination of the CDN infrastructure. In order to do this, a tracker maintains (1 ) information about content at each end point through consistent hashing and (2) collects resource usage statistics periodically from each end point. As part of this, the tracker maintains information like number of outbound bytes, number of inbound bytes, number of active connections for each bucket, size of content being served etc.
• a region must have exactly one tracker and DNS server authoritative for that region.
• the Live stream on the other hand defines meta-data for source URL of the live stream, the live-splitter, geo-blocking, whitelist / blacklist, etc.
• Partitions The API defines methods to create a partition object that returns a PID, return a collection of partitions, retrieve information about (subnets in) a PID, update / create a PID and delete a PID.
• a network edge defines the cost of transporting one unit of data between two PIDs (or simply, the weight of an edge).
• the API defines methods to get the costmatrix (a matrix that defines the cost between every partition pair), create, update and retrieve the cost between two PIDs. As a default, the cost between two PIDs is set to a large value.
• the API also defines methods to retrieve all edges with a given origin PID, retrieve all edges to a destination PID.
• the topology described at a Topology Server can extend far beyond its OB boundaries. Only the OB point of view of the network topology is described. As an example, an OB in Spain creates a partition that defines all the subnets in USA while another OB in Argentina creates partitions that defines all of the subnets of USA.
• DNS server This allows the DNS manager to remotely manage the SQL database at the TLD DNS server.
• DNS server authoritative for t-cdn.net domain may also be authoritative for the sub-zone "es".
• the DNS server detects that and will attempt to send the DNS query to one of the endpoints to first resolve the closest datacenter that may best serve the request.
• the CDN incorporates the latest network cost in identifying end points that are best located to serve content to requesting end users based on least network cost.
