-- A Time-Division Multiple Access (TDMA) Media Access Control (MAC), which provides guaranteed bandwidth and low latency for applications that have strict Quality of Service (QoS) requirements, such as IPTV. G.hn's MAC also includes support for multiple priority levels, to ensure that an application, such as peer-to-peer file transfers, do not impact the performance of higher-priority applications like IPTV, VoIP, or online gaming. -- A Logical Link Control (LLC) sub-layer that ensures delivery of data over home electrical wiring. G.hn's LLC employs an advanced selective ARQ (Automatic Retransmission Request) protocol that automatically re-transmits data affected by noise and provides error-free end-to-end Ethernet services to any G.hn device on the network connected to power lines, phone lines, or coaxial cables. -- A procedure for efficient aggregation of multiple Ethernet messages over a single MAC Protocol Data Unit (MPDU). This significantly increases network throughput to support applications such as High-Definition IPTV that have large bandwidth requirements. G.hn specifies line data rates up to 1 Gbit/s, significantly higher than current generation wired networking technologies. -- State-of-the-art security based on AES (Advanced Encryption Standard - FIPS-PUB-197) and CCM (Cipher Block Chaining Message Authentication Code - NIST-SP-900-38C).The functional areas of the DLL that are now adopted as Baseline Text ensure that G.hn can support applications with strict QoS requirements (such as high-definition video), and that G.hn can be used in products for the service provider, consumer electronics, and PC markets. "The United Nations' ITU-T continues to make rapid progress towards a single unified standard for delivering multimedia content around the home," said Matthew Theall, president of the HomeGrid Forum. "Additionally, this next-generation standard has been actively driven by some of the world's leading service providers, consumer electronics manufacturers and PC companies." HomeGrid Forum is actively promoting and developing compliance and interoperability test programs for the G.hn standard. These programs will simplify the development, purchase, installation, and use of HomeGrid Forum-Certified products through the entire ecosystem of silicon providers, services providers, consumer electronics companies, personal computer companies, and retailers. The group continues to seek new members that can help drive the success of G.hn. About HomeGrid Forum HomeGrid Forum is a global, non-profit trade group promoting the International Telecommunication Union's G.hn standardization efforts for next-generation home networking. HomeGrid Forum promotes adoption of G.hn through technical and marketing efforts, addresses certification and interoperability of G.hn-compliant products, and cooperates with complementary industry alliances.
