Due to the integration of the network safety apparatus and an exchanger into one host, the utility model has the advantages of low cost, powerful function, etc.
Description
Technical field
The utility model relates to Network Security Device.
Background technology
Existing small-sized local area network (LAN) also needs switch except having required Network Security Device such as security gateway.Switch and Network Security Device usually are two separate equipment, and this brings difficulty to management when cost increases.
Therefore, if can when network security capability and function of exchange are provided, reduce number of devices, will be very favorable.
Summary of the invention
The purpose of this utility model is, at above the deficiencies in the prior art, provides a kind of new-type network safety means, and Network Security Device and switch are integrated.
The utility model, be that one of them or several network controller with Network Security Device becomes the exchange network interface through exchange chip, its hardware typically is characterised in that: exchange chip (or hub chip) directly is integrated on the integrated circuit board of Network Security Device, Network Security Device has had the function of switch, the integrated circuit board (or integrated circuit board of concentrator function) that perhaps will have function of exchange is connected to the Network Security Device mainboard by the extrapolation mode, make Network Security Device integrated the function of switch (or hub).
Comprise according to Network Security Device of the present utility model: the network security device of network security capability is provided, is connected with at least one integrated network card or ethernet controller, and have at least one network interface and external network or other subnet links to each other; And at least one switch, each switch is connected respectively on the described integrated network card or on the ethernet controller, and each switch is connected with many computers in the local area network (LAN) by a plurality of network interfaces respectively.
Because the utility model is integrated into Network Security Device and switch in the main frame, have advantages such as cost is low, function is strong.
Description of drawings
Fig. 1 is the schematic block diagram of Network Security Device 1 of the present utility model; And
Fig. 2 is the schematic block diagram of the concrete example of Network Security Device of the present utility model.
Embodiment
Describe the utility model in detail below with reference to accompanying drawing.Fig. 1 is the schematic block diagram of Network Security Device 1 of the present utility model.As shown in Figure 1, Network Security Device 1 of the present utility model comprises: the network security device 2 that network security capability is provided, security gateway for example, it is connected with at least one integrated network card 6 or ethernet controller 3, and has at least one network interface and external network or other subnet links to each other; At least one switch 4, its each be connected respectively to an ethernet controller 3 or integrated network card 6, and be connected with a plurality of network interfaces 5 respectively, wherein each network interface 5 is connected with computer in the local area network (LAN) respectively.As shown in fig. 1, can there be partly integrated network interface card 6 or ethernet controller 3 not to be directly connected to network interface 5 fully by switch.In addition, it will be understood by those skilled in the art that integrated network card 6 can itself just have network interface fully, among Fig. 1 integrated network card 6 is connected to a network interface that separates with it 5 just for the ease of understanding the utility model.Network Security Device 1 can be by network security device 2 network interface or be connected to external network or other subnets by network interface card in the integrated network card 6 or ethernet controller 3.
Current existing multiple network safety device can be used, as fire compartment wall, network cryptographic machine, security gateway, gateway, intruding detection system, PAA etc.Typically, network security device 2 is by device (not shown) be combined intos such as master chip, memory, internal memories, and master chip for example can be POWER PC or INTELP4CPU+845G north and south bridge, reads program stored and data in the memory, and utilize internal memory, realize network security capability.
In addition, current existing multiple available ethernet controller is as Intel 825551QM 10/100Mb ethernet controller.Ethernet controller is connected or directly is integrated into master chip with the master chip of network security device 2 is to well known to a person skilled in the art general knowledge.For example, ethernet controller 3 can be integrated in the master chip, also can adopt independent chip to realize.
Switch 4 in the utility model can be an exchange chip, or hub chip.Link together with network controller.As example, exchange chip can adopt the RTL8305SB exchange chip, hub chip can be the TAMARACK chip, and the MII/GigaMII interface (Media Independed Interface, medium independent interface) of the standard by IEEE definition is received ethernet controller.And expand 4 exchange mouths from a network card chip.It will be understood by those skilled in the art that exchange chip is not limited to the concrete model that provides as example here, ethernet controller and exchange chip also are not limited to has only the MII connected mode, and the quantity of the exchange mouth that expands also is not limited to 4.
Switch 4 also can adopt the function of exchange plate of customization, and integrated circuit board links to each other with ethernet controller by the interface of customization, is directly installed in Network Security Device 1 cabinet,, is connected to ethernet controller 3 by the extrapolation mode that is, realizes the function of exchange.
Perhaps, also can be the mixed mode of aforementioned two kinds of patterns.That is, some switch 4 is exchange chips, connect together with ethernet controller 3 nets, and another part switch 4 is function of exchange plates, is connected to ethernet controller 3 by the extrapolation mode.
Below, as example, the implementation more specifically of Network Security Device of the present utility model is described with reference to figure 2.POWER PC405 chip links to each other with internal memory, memory by bus, and the function of network security is provided.POWER PC405 chip links to each other with a network card chip, and this network card chip is connected to a network interface by transformer.Network Security Device shown in Figure 2 can be connected to external network or other subnet by the network interface that links to each other with this network card chip.Integrated ethernet controller A and integrated ethernet controller B are arranged in the POWER PC405 chip.Integrated ethernet controller A links to each other with exchange chip, and exchange chip is connected to 4 network interfaces by transformer.Integrated ethernet controller B links to each other with Ethernet PHY, and Ethernet PHY is connected to 1 network interface by transformer.Wherein by exchange chip being connected to integrated ethernet controller A, and function of exchange is provided for this Network Security Device.It will be understood by those skilled in the art that the utility model is not subjected to here the restriction with reference to figure 2 described each details.
In the superincumbent description,, provided the model of several chips as example, and concrete connected mode.But the utility model is not limited to the chip of these concrete models, also is not limited to these concrete connected modes.It will be understood by those skilled in the art that the chip that can adopt other suitable model fully,, realize Network Security Device of the present utility model with other concrete connected mode.
