Description
Technical field
The utility model relates to a kind of network service router.
Background technology
Router connects each local area network (LAN) in internet, the equipment of wide area network, it can automatically be selected according to the situation of channel and set route, with optimal path, signal is sent by tandem, router is the hinge of internet, " traffic-police ", current router is widely used in all trades and professions, the product of various different class become realize various backbone network inside connect, the main force of key internetworking and backbone network and internet interconnection business, the main distinction between routing and swiching machine is exactly that switch occurs in the OSI Reference Model second layer (data link layer), and route occurs in third layer, i.e. network layer, this difference determines routing and swiching machine and needs to use different control informations in the process of mobile message, the mode that both realize respective function is thus different.
Router is for connecting multiple network separated in logic also known as gateway device, so-called logical network represents an independent network or a subnet, when data are transferred to another subnet from a subnet, routing function by router has come, therefore, router has the function judging the network address and select IP path, it can in Multi net voting Interconnection Environment, set up and connect flexibly, available diverse packet is connected various subnet with media access method, router only accepts the information of source station or other routers, belong to a kind of InterWorking Equipment of network layer.
Router divides local router and remote router, and local router is used to interconnection network transmission medium, as optical fiber, coaxial cable, twisted-pair feeder; Remote router is used to connect remote transmission medium, and requires to establish the router in simulator standby accordingly, as auxiliary tone modulator-demodulator wanted by telephone wire, wirelessly will pass through wireless receiver, transmitter.
Current existing router knot is complicated, and install inconvenient, stability in use is poor.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to use, good stability, safe and reliable network service router.
For solving the problem, the utility model adopts following technical scheme: a kind of network service router, comprise CPU, AC/DC power supply adaptor, filter and synchronous DRAM, described CPU, filter and AC/DC power supply adaptor are electrically connected successively, described filter is active filter, described CPU is connected by signal with synchronous DRAM, described synchronous DRAM side is provided with FLASH flash memory, described FLASH flash memory is connected by signal with CPU, clock-signal generator and reset circuit is provided with above described CPU, described clock-signal generator and reset circuit are electrically connected with CPU respectively, exchange control unit and ethernet controller is provided with below described CPU, described CPU is electrically connected with exchange control unit and ethernet controller respectively.
As preferably, described exchange control unit side is connected with LED light, conveniently shows working condition.
As preferably, described LED light is provided with more than one, keeps display effect good.
As preferably, described ethernet controller side is connected with hub, and ethernet controller is convenient to be linked in network by hub.
As preferably, described ethernet controller is provided with more than one RS-232 interface, keeps easy installation and reliable.
The beneficial effects of the utility model are: the AC/DC power supply adaptor of setting conveniently regulates power supply, filter can keep stable operating voltage, synchronous DRAM can be real-time storage data, clock-signal generator can carry out synchronously, keep synchronous DRAM constantly to refresh to ensure that data are not lost, reset circuit conveniently automatically resets.
