Abstract
The invention discloses a method of forming a correct forwarding table through periodic broadcasting or multicast of a CPU (Central Processing Unit). The method comprises the following steps that a CPU unit forms a forwarding table which is unidirectional to the CPU unit through periodic broadcasting or multicast, when a PC (Personal Computer) unit follows the correct forwarding table to transmit a data packet to the CPU unit, the CPU unit forms the correct forwarding table to the PC unit. According to the method, the correct forwarding table can be formed by a switch and the PC without adopting a manner of bidirectional broadcast, so that broadcast is unnecessary for switching, the CPU unit cannot receive the unnecessary broadcast, the CPU unit concentrates on the related functions and cannot waste on discarded broadcast packets, so that a high-performance CPU chip is not needed, and only the CPU chip with the common performance is adopted; through modifying a register, an MAC (Media Access Control) unit controls the broadcast flow direction, so that implementation is convenient and any function of the MAC unit cannot be affected.
Description
Technical field
The present invention relates to electronics field, specifically a kind ofly to be broadcasted by cpu cycle or multicast forms the method correctly transmitted.
Background technology
At Ethernet switch, router, in protocol converter and metering device, often adopt independent CPU element and MAC unit, two unit are connected by CPU-MAC interface, main employing MII interface, gmii interface or Ethernet interface interface shape, the effect of MAC unit has been the forwarding of Ethernet bag, the effect of CPU element is from MII interface, gmii interface or Ethernet interface are accepted business ether bag, to go forward side by side row relax, by MII interface, MII interface or Ethernet interface provide web to configure, these functions of the equipments such as telnet configuration, CPU element accepts clean culture, the business such as multicast, network management data bag, also receive a large amount of broadcast data packet simultaneously, although broadcast data packet is not the packet wishing to want, but this is PC unit access CPU element communication needs, be generally used for web, telnet webmaster, form correct the transmitting and corresponding table of on-line apparatus, need to rely on broadcast.
Processing mode now for broadcast packet is that MAC unit does not limit the broadcast packet being dealt into CPU element, allows CPU oneself go process; CPU element is come, even if the broadcast packet received is useless, also must processes and abandon.When a large amount of broadcast packets impacts CPU element, often allow CPU element process in time abandon, the disposal ability consumption making CPU element a large amount of is in this useless work, also normal process is allowed to have no chance to carry out, often take high performance cpu chip now, even if when broadcasting impact, also normal process broadcast packet can be abandoned, therefore actual this high-performance impacts for useless broadcast to prepare, waste resource.
Summary of the invention
The object of the present invention is to provide a kind of to be broadcasted by cpu cycle or multicast forms the method correctly transmitted, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
To be broadcasted by cpu cycle or multicast forms the method correctly transmitted, comprise the steps: that (1) closes the One-to-All Broadcast from MAC unit to CPU element in the register of MAC unit, keep the One-to-All Broadcast from CPU element to MAC unit; (2) there is a broadcast packet or multicast packets at set intervals in CPU element, and broadcast packet or multicast packets can flood; (3) MAC unit, switch and all PC unit all define the correct list of CPU element; (4) when administration PC unit sends web unicast data to CPU element, through switch and MAC unit, transmitting of PC unit is just formed into; (5), when web unicast data arrives CPU element, wherein source mac and source ip, will form the mac-ip correspondence table of CPU element.
As the present invention's further scheme: described CPU element, every 250s, a broadcast packet or multicast packets occurs.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention does not take the mode of bidirectional broadcast, also switch and PC unit can be made to form correct transmitting, making to broadcast does not become the necessary of exchange, CPU element would not receive unnecessary broadcast, CPU element is absorbed in relevant function, and do not waste and abandoning on broadcast packet, therefore need not adopt high performance cpu chip, adopt the cpu chip getting general performance; By amendment register can make MAC unit controls broadcasting stream to, it is convenient to realize, and does not affect any function of MAC unit itself.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
To be broadcasted by cpu cycle or multicast forms the method correctly transmitted, comprise the steps: that (1) closes the One-to-All Broadcast from MAC unit to CPU element in the register of MAC unit, keep the One-to-All Broadcast from CPU element to MAC unit; (2) there is a broadcast packet or multicast packets every 250s in CPU element, and broadcast packet or multicast packets can flood; (3) MAC unit, switch and all PC unit all define the correct list of CPU element; (4) when administration PC unit sends web unicast data to CPU element, through switch and MAC unit, transmitting of PC unit is just formed into; (5), when web unicast data arrives CPU element, wherein source mac and source ip, will form the mac-ip correspondence table of CPU element.
CPU element is formed into unidirectional the transmitting of CPU by periodic multicast or broadcast, and follow correct packet of transmitting when PC unit and be dealt into CPU element, CPU element just defines correct the transmitting of PC unit.
The present invention does not take the mode of bidirectional broadcast, also switch and PC unit can be made to form correct transmitting, making to broadcast does not become the necessary of exchange, CPU element would not receive unnecessary broadcast, CPU element is absorbed in relevant function, and do not waste and abandoning on broadcast packet, therefore need not adopt high performance cpu chip, adopt the cpu chip getting general performance; By amendment register can make MAC unit controls broadcasting stream to, it is convenient to realize, and does not affect any function of MAC unit itself.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned execution mode, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
