eCPRI Message Format • Four byte eCPRI common header followed by a variable length eCPRI payload 27. Common Header Format • "Protocol Revision" indicates the protocol version # (v1.0 → 000b) • "Message Type" indicates the type of conveyed service • "C" is eCPRI message concatenation indicator • "Payload Size" is the ...The coexistence of 4G and 5G will mean that operators need to serve a mix of RAN architectures with converged mobile transport to avoid costly overlays. This includes supporting existing fronthaul protocols (CPRI, OBSAI) and new 5G-specific protocols (eCPRI, NGFI). Figure 1: RAN evolution with different architectures in the mix
The eCPRI function for RXT-6200 and RXT-6000e modules support eCPRI standard compliant test traffic at Layer2 and Layer4 (UDP) with up to 32 independent test streams. The dual test port platform ...eCPRI v1.1, havevery stringent requirements for fronthaul networks. Thus, to relax the requirements, there have been many proposals to split the fronthaul, such as centralizing and/or virtualizing some functions while others remain distributed and co-located with the remote radio head (RRH) at the cell site .Comcores is a Key supplier of digital IP-cores and design services for digital subsystem solutions. Comcores is a world-class technology company delivering the most cost-effective and reliable IP cores for ASIC, FPGA and Embedded Systems. The IP cores are extensively interoperability tested and thoroughly verified by state-of-the-art tools.For that reason, eCPRI is a more suitable candidate for 5G, being able to match the requirements of the 5G mobile networks. From Table 1, it becomes evident why the eCPRI's inter-PHY layer splits are the main candidates for the 5G functional split. Reduction of fronthaul data by 10 to 50 times is important, while the support for E split remains.
eCPRI is the latest radio access network fronthaul standard. eCPRI messages can be just UDP/IP packets.
I now have v4.97 firmware with eCPRI technology enabled. I have tried to send an eCPRI message from one port on the STC to another port but the Rx counter on the Stream block results view is not incrementing, the Tx counter is incrementing every time the message is received.The new specification, known as eCPRI, or CPRI over Ethernet, introduces improved efficiency to match the speed and bandwidth requirements of 5G Fronthaul networks.CPRI - HuaweieCPRI Message Format • Four byte eCPRI common header followed by a variable length eCPRI payload 27.
