Marvell Introduces Carrier-Optimized Ethernet Access and Edge Switches
Innovative radio access network (RAN) disaggregation and virtualization solutions depend on the network's ability to deliver high-performance deterministic connectivity for fronthaul streams within ubiquitous and flexible Ethernet-bridged networks. To support the new RAN deployment models for radio access fronthaul applications, the Prestera DX 7300 family integrates highly accurate time synchronization, 802.1CM Time-Sensitive-Network (TSN) for fronthaul, network slicing and native eCPRI-aware processing. The switches are part of
Ever-increasing processing demands in the metro data center are driving the need for high-bandwidth data movement at an economical cost. The Prestera DX 7300 series of switches integrate 56Gbps SerDes, high-capacity MACsec and advanced processing that can be matched with pluggable 400G-ZR optical modules. This functionality enables system manufacturers to develop solutions for multi-access edge computing (MEC) and data center interconnect (DCI) applications that benefit from traffic efficiency, openness and the optimized cost structure of packet Ethernet networks.
"As 5G brings rigorous data protection and performance demands to the transport network, the infrastructure has to meet the requirements for secured communications at higher speeds and data rates to support emerging use cases," said
"The emerging carrier solutions spanning edge, metro data center and 5G depend on strong and scalable network performance and security," said
The Prestera DX 7300 devices are
Powered by a modern Marvell Software Development Kit (SDK), the Prestera DX 7300 switches share a set of common application programming interfaces (APIs) with other Marvell switching products. This interoperability is designed to simplify the development effort and accelerate system introduction.
