Media Grid Engines (or MGEs) are Media Grid Objects of one of the following types :

  • Media Grid Engine = Origin Server
  • Media Grid Engine = Cache Server
  • Media Grid Engine = Mediation Controller
  • Media Grid Engine = Edge Server

The Media Grid Engines offer overlapping subsets of the functionalities listed below.

  • MGE = Origin Server : Ingests content,Wraps it into a Content MGO (CMGO), Stores, creates, and forwards CMGOs. Authenticates MGEs requesting CMGO decryption, serves decryption ISTPs
  • MGE = Cache Server :Accepts, stores, creates, and forwards CMGOs
  • MGE = Mediation Controller : Manages, accelerates and mediates ISTP traffic from "best-effort" traffic. Inter operates with other Media Grid Engines, foreign routers
  • MGE = Edge Server :Accepts, disassembles CMGO; delivers content to consuming client

NOTE: Creating a CMGO generates a decryption ISPK, which resides with the corresponding MGO = OS. The encryption ISTP resides as part of the CMGO,and is used to authenticate requests for decryption.

Origin servers may be hosted in cloud services infrastructure or other virtualized environments. Cache and edge servers will be typically deployed on dedicated hardware subsystems or using Network Function Virtualization (NFV). These hardware subsystems must have a minimum of 2 petabytes of storage and equivalent server processing power (e.g.3.2GHz Intel Quad Core XEONs). Currently, the media grid engine software runs on Fedora 16 operating system with 8 Gigabytes of memory. The project may be ported to other Linux operating systems as deemed appropriate by the working groups. InterStream expects these servers to be deployed with 10 Gigabyte Ethernet interfaces.
