详细描述：The MorethanIP Switch solution implements a highly programmable and flexible platform with an embedded RISC processor and support for the emerging IEEE1588 version 2 timing control protocol. The MorethanIP Switch provides an ideal highly integrated platform to develop a wide range of applications (Industrial, AVB) to support emerging standards (AVB, IEEE1588). The Switch implements, per port, up to four prioritized queues, which provide Quality of Service (QOS) to critical class of services. The Switch is programmable to classify traffic from the 4-Bit VLAN priority field on the VLAN info field, 6-Bit DiffServ Layer 3 Code Point (Ipv4) or the 8-Bit Class of Service (Ipv6) and each physical port can also be weighted. To meet the stringent latency requirements of Industrial and AVB (Audio, Video Broadcast) application and to better support triple play application, the Switch implements a low latency cut-through operation option that provides fast, and predictable, Frame forwarding. Advanced domain and storm protection options provide efficient user traffic management and reduce superfluous traffic. For industrial automation, Telecom or AVB applications the IEEE 1588 standard is becoming the main technology for precise time synchronization on Ethernet networks. IEEE1588 provides accurate clock synchronization for distributed control nodes to overcome one of the drawbacks of Ethernet. The Switch provides support for IEEE 1588 version 1 ordinary and boundary clock schemes and also implements IEEE 1588 version 2 transparent E2E (End to End) and P2P (Peer to Peer) The Switch implements full featured 10/100Mbps Ethernet MACs compliant with the IEEE802.3-2002 standard. The MAC layer provides compatibility with Full Duplex Ethernet LANs and legacy Half Duplex Ethernet LANs. The Switch can, optionally, implement an Uplink interface and MorethanIP provides a wide range of system (e.g. PCI Express) and Telecom interfaces (e.g. GMII, RGMII Gigabit, XGMII 10Gigabit interfaces) for unprecedented flexibility. The embedded RISC processor can be used for management (e.g. SNMP), for high level networking functions such as Spanning Tree, Rapid Spanning Tree and can terminate TCP/IP connections. The embedded processor removes the need of an external processor
