While standard Ethernet multi-port Ethernet Switches can be used to meet a number of applications, the MorethanIP programmable switch platform can be configured to provide more flexibility. For example, standard Ethernet Switches typically only implement physical Ethernet interfaces such as MII (Fast Ethernet ports) or GMII (Gigabit Ethernet port) and therefore require an adaptation device (e.g. FPGA, ASIC) if one port needs to be connected to, for example, a PCI bus, a SONET / SDH framer for POS (Packet Over SONET / SDH) or EOS (Ethernet Over SONET / SDH), DSL line processors or voice processors for VoIP (Voice over IP) applications.
For advanced switching scenarios where various types of traffic like voice, video and data are mixed the switch can offer quality of service treating the various traffic classes with different priorities ensuring better service quality. The Switch with Quality-of-Service (QoS) support enables to handle complex traffic scenarios for improved network service.
The MorethanIP switch engine implements a programmable number of generic FIFO interface (Atlantic) ports, which connect seamlessly to any Interface Core from MorethanIP, for example the Ethernet MAC Cores, or to any third party Core supporting the Atlantic SOC (System on a Chip) standard. This allows flexible interfacing to e.g. Ethernet using Ethernet MAC Cores. The MorethanIP switch is implemented as a System on Chip (SOC) and it embeds a Hardware switch engine, for performance, and a 32-Bit embedded processor, which performs address learning, aging, migration tasks and which can be used to implement further control and management functions such as e.g. Spanning Tree.
