The fire wall is characterized by further comprising a switching chip, a protocol converting chip, a PHY (Physical Layer) chip and a back panel. The switching chip is connected with the network card chip through an XAUI (X Attachment Unit Interface); the switching chip is connected with the bridge chip through a PCI (Programmable Communications Interface); the switching chip is connected with an input end of the protocol converting chip; an output end of the protocol converting chip is connected with eight gigabit electric interfaces; the switching chip is connected with four gigabit optical interfaces; the switching chip is connected with the PHY chip; the PHY chip is connected with two 10-gigabit optical interfaces; and the switching chip is connected with the back panel. The fire wall provided by the utility model uses a design structure of a fire wall and a switchboard, uses the high-property gigabit switching chip, and provides the two 10-gigabit optical interfaces, the eight gigabit electric interfaces and the four gigabit optical interfaces. For a user, the fire wall provided by the utility model not only improves the use ratio of the equipment but also solves the problems of complex network layout, poor expansibility and the like.

Description

A kind of fire compartment wall

Technical field

The utility model relates to network communication field, especially a kind of fire compartment wall.

Background technology

At present; X86 is the standard numbering abbreviation of an intel universal computer series; Also identify a cover general calculation machine instruction set, the X86 platform typically refers to one of use or many host CPUs come processing service data, and network card chip and CPU then transmit data through the PCI/PCIE bus.Because of its high flexibility and extensibility are used as main fire compartment wall development platform always.The firewall functionality that depends on the X86 framework is mainly realized by software, can adjust accordingly according to user's actual needs, increases or reduce functional module, and this is more flexible for product, and function is also very abundant.

The fire compartment wall of prior art comprises CPU, bridge chip (PCH), network card chip etc., confirms the port speed of this fire compartment wall according to the difference of the speed of network card chip.Because the restriction of the PCI/PCIE bus standard of cpu is so the limited amount of its network card chip causes the limited of its port number.

Therefore, need a kind of firewall box that a plurality of ports can be provided, to reduce the complexity and the operation cost of general plan.

The utility model content

In the utility model content part, introduced the notion of a series of reduced forms, this will further explain in the embodiment part.The utility model content part of the utility model does not also mean that key feature and the essential features that will attempt to limit technical scheme required for protection, does not more mean that the protection range of attempting to confirm technical scheme required for protection.

The main purpose of the utility model is to provide a kind of fire compartment wall, comprises central processing unit, bridge chip and network card chip, it is characterized in that also comprising exchange chip, protocol conversion chip, PHY chip and backboard; Said exchange chip is connected through the XAUI interface with said network card chip; Said exchange chip is connected through pci interface with said bridge chip, the input of exchange chip connection protocol conversion chip, and the output of protocol conversion chip connects 8 gigabit electrical interfaces; Exchange chip connects 4 gigabit optical interfaces; Exchange chip connects the PHY chip, and the PHY chip connects 2 10,000,000,000 optical interfaces, and exchange chip connects backboard.

Said backboard can be arranged to 12 10,000,000,000 optical interfaces.

Said exchange chip adopts BCM56314.

Said PHY chip adopts BCM8726.

Said gigabit electrical interface is the RJ-45 interface.

The utility model has adopted the design architecture of fire compartment wall+switch; Adopt high performance gigabit exchange chip; Two 10,000,000,000 optical interfaces, eight gigabit electrical interfaces, four gigabit optical interfaces are provided; For the user, both improved usage ratio of equipment, solved problems such as network design complicacy, autgmentability difference again.

Further feature of the utility model and advantage will be set forth in specification subsequently, and, partly from specification, become obvious, perhaps understand through implementing the utility model.The purpose of the utility model can realize through the structure that in the specification of being write, claims and accompanying drawing, is particularly pointed out and obtain with other advantages.

Description of drawings
