In the beginning of 2018, Huafei Tech HF-Ring V2 Loop Redundancy Protocol Software, HF-Ring Sub-Ring Sub-net Redundancy Protocol Software, Managed SDI Video Transmission operation system（HF-MSDIEOS）three Software Certifications have been registered in National Copyright Administration of China, Huafei Tech ‘s development and researching ability was agreed once again.

HF-Ring Loop Network Redundancy Protocol improve the convergence performance after the network broken.

On Ethernet, for backup the link, improve the reliability of network, usually will use redundancy link. Due to redundancy will create loop on the internet, may cause broadcast storm and MAC table not stable and other phenomenon, so that the users communication quality will be effected, even break the communication.

For improving the convergence performance after network broken, HuaFei propose HF-Ring,HF-Ring v2(new version of HF-Ring) loop network redundancy protocol, and HF-Ring Sub-Ring Sub loop protocol and other loop protocol, Sub-Ring could realize HF-Ring tagent ring and other topological structure, could have  configure complex group network more flexible. Now obtain national computer software athurity certification.

HF-Ring Technology have below advantages than STP/RSTP/MSTP and other layer 2 loop protocol:

>High spped convergence rate 

>Network expansion without quantity limit

>Not cut back after broken link recovery

>Simple configuration

Managed SDI video transmitter installation operation system, which is convenient to cusotmer to monitoring the transmitter and receiver equipment information.

Managed SDI video transmitter installation operation system, which is HF-MSDIEOS software, support network management function, customer could access and manage equipment through WEB,Telnet and CLI, and realize below functions:

>All digital, uncompressed, high definition optical fiber transmission

>Support 12G/6G/3G/HD/SD multiple serial digital signals

>Support ST2082-1,ST2081-1,ST-424,ST-292,ST-259 serial digital video standard, and compatible to support DVB-ASI, AES10.

>Support 270Mbps, 1.485Gbps, 2.97Gbps, 5.94Gbps, 11.88Gbps

>Support remote internet management function through WEB/TELNET/SNMP network.

>Support 4U chassis Integrated Management Platform, and provide platform management function based on Ethernet.

>10G optical fiber transmission technology, large switching fabric, and easy to upgrade.

>Industrial design, modularization design make the equipment more reliability and flexible.
