Description
Technical field
The present invention relates to a kind of MoCA terminal, particularly a kind of MOCA multiport terminal can realize it is managed.
Background technology
The MoCA technology is based on coaxial cable and realizes interconnected international standard between the household internal network equipment; It is operated in high band; Higher physical layer transmission bandwidth can be provided; The MoCA technology is used for the broadband access (being c.LINK-Access) of hfc plant, can well solves that the access bandwidth that existing network exists is low, network connective stability difference gets problem.
Owing to the MoCA technology is formulated for home networking, portion within the family, a plurality of terminals of local side band, a network equipment only need be with in each terminal.
And be used for Access Network, and be a plurality of terminals of local side band equally, but a terminal but need be with a user, and a user have multiple business, this just needs the terminal to have a plurality of ports to support multiple business.
And multiple business and deposit; (Quality of Service is a service quality to need the network equipment to have higher QoS; Being a kind of security mechanism of network, is with solving a kind of technology of problems such as network delay and obstruction) assurance, this just needs operator that parameters such as the bandwidth of MoCA terminal prot, priority are carried out reasonable configuration; Just can make the message that requires to have higher prior have preferential forwarding power; And,, need upgrade the configuration of user terminal constantly in order to adapt to professional variation along with further the carrying out of business.
Thus, each port at multiport terminal must carry out the setting of information such as port bandwidth restriction, VLAN, priority through remote modes such as SNMP, web, Telnet.
Summary of the invention
The purpose of this invention is to provide a kind of manageable multiport MoCA terminal, the multiport at MoCA terminal is managed with realization.
In order to realize above-mentioned purpose, the manageable multiport MoCA of the present invention terminal comprises MoCA master chip, MCU and exchanger chip.
The MoCA master chip is connected with exchanger chip through the MII interface to be accomplished forwarding of data and becomes PHY pattern or MAC pattern to the MII interface configuration through configuration register.
MCU links to each other through the SMI bus with the MoCA master chip; The MoCA master chip uses the SMI bus to download code to its startup of guiding in the MoCA master chip through MCU; And be configured through SMI bus operation register and accomplish whole initial work; When normal operation, the operating state of monitoring MoCA master chip.
MCU also links to each other with exchanger chip through another group SMI bus, comes control exchanger chip separately.
Said exchanger chip is connected with a plurality of RJ485 interfaces.
The MoCA master chip at the manageable multiport MoCA of the present invention terminal can have big flexibility with the exchanger chip butt joint of nearly all band MII interface on the hardware designs.The present invention can conveniently realize the management to switch through the cooperation of MoCA management channels.On the MII of MoCA master chip interface, connect the switch of difference in functionality, can realize different configuration features, can satisfy multiple services demand.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is single port terminal MOCA master chip and PHY connection layout;
Fig. 2 is a manageable multiport MoCA terminal connection layout;
Fig. 3 is the hardware catenation principle figure of MOCA master chip and exchanger chip, MCU part.
Embodiment
As shown in Figure 1, because MoCA single port terminal is MII (Medium Independent Interface GMII) interface through the MoCA master chip realization forwarding of data that is connected with the PHY chip.MII is the Ethernet industry standard of IEEE-802.3 definition, and it comprises a data interface, and the management interface between MAC and the PHY.
Data-interface is made up of 16 holding wires altogether, comprises two independent channels that are respectively applied for transmitter and receiver, and every channel all has data, clock and the control signal of oneself.
SMI (Serial Management Interface) bus is used in management, and it is a dual signal interface: be respectively MDC and MDIO, one is clock signal, and another is a data-signal.Through the register of SMI bus read-write PHY, PHY can kept watch on and control in the upper strata.
Utilize this function, the MoCA master chip can dock with the exchanger chip that has the MII interface equally, substitutes PHY with exchanger chip and accomplishes forwarding of data; And the MoCA master chip can become PHY pattern or MAC pattern to the MII interface configuration through configuration register, can have big flexibility on the hardware designs with the exchanger chip butt joint of nearly all band MII interface like this.
The MoCA master chip is that 8 MCU through the outside use the SMI buses to download code to reboot its startup in the MoCA master chip, and is configured through SMI bus operation related register and accomplishes whole initial work; When normal operation, monitor the operating state of MoCA master chip constantly.
This shows that the MOCA master chip is from slave mode.And in MoCA single port terminal, the SMI interface of PHY is and the public same group of bus of the SMI interface of MoCA master chip, and is as shown in Figure 1, just do not conflict mutually through becoming the address configuration of PHY with the address of MoCA master chip on the hardware.After connecting exchanger chip, though the register address of MoCA master chip can still conflict with the register of exchanger chip through the external hardware configuration mutually.So, adopt another group SMI bus to come control exchanger chip separately in the present invention, as shown in Figure 2, scheme is following:
The MoCA master chip is connected with exchanger chip through the MII interface to be accomplished forwarding of data and becomes PHY pattern or MAC pattern to the MII interface configuration through configuration register.
MCU links to each other through the SMI bus with the MoCA master chip; The MoCA master chip uses the SMI bus to download code to its startup of guiding in the MoCA master chip through MCU; And be configured through SMI bus operation register and accomplish whole initial work; When normal operation, the operating state of monitoring MoCA master chip.
MCU also links to each other with exchanger chip through another group SMI bus, comes control exchanger chip separately.
As shown in Figure 3, in the concrete design of the present invention, being connected with RXD0 [0..3] bus of exchanger chip behind exclusion of the EMAC_RXD [0..3] of the MII interface of MoCA master chip connection; Being connected with TXD0 [0..3] bus of exchanger chip behind exclusion of EMAC_TXD [0..3] connection; Two groups of middle exclusions of bus play the impedance matching effect.Link to each other through a resistance MoCA master chip EMAC_RX_DV, EMAC_TXCLK, EMAC_TXCLK_IN with RXDV0, MIIO_TXCLK, MIIO_RXCLK, the TXEN0 of exchanger chip respectively.And be set to the MAC pattern through software arrangements MoCA master chip, be arranged to the PHY pattern to switch through Hardware configuration, thereby accomplish whole data path.
Simultaneously, two I/O mouth simulation MDC/MDIO buses MCU link to each other with the MAC_MDIO bus with the EMAC_MDC of MoCA master chip, realize the control to MoCA; Also be modeled to another group MDC/MDIO bus to two I/O mouths in addition of MCU, link to each other with MDIO0 with exchanger chip MDC0, when the information of configuration switch is received through issuing passage in the MoCA terminal; MCU is set to configuration information through this bus the related register of exchanger chip; Realize configuration feature, simultaneously, MCU can obtain the state of exchanger chip in real time through these two buses; Such as port connection state etc., thereby realized control to exchanger chip.Exchanger chip is connected with a plurality of RJ485 interfaces.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
