Description
Technical field
The present invention relates to be applied to Ethernet passive optical network (EPON) technology, be meant the register method of optical network unit among a kind of EPON (ONU) especially.
Background technology
Along with the internet develop rapidly and Web TV new business such as (IPTV), new interface applications are gone into bandwidth and are proposed more and more higher requirement, optical fiber inserts the inevitable direction that becomes the broadband access network development.Consider that from the maturity and the operation cost aspect of technology EPON is the main implementation method that optical fiber inserts, and also is the most potential access technology.
The EPON system adopts the topological structure of the shared point in broadband to multiple spot, each optical line terminal (OLT) connects a plurality of ONU by Optical Distribution Network (ODN), wherein descending employing broadcast transmission, up employing time division multiple access inserts (TDMA) mode, come coordination data effectively to send and reception with Multi-point Control Protocol (MPCP), to guarantee that up direction only allows an ONU transmission professional at any time in system's running.
OLT supports MAC Address based on ONU to the ability that the ONU legitimacy authenticates, and refuses the access of illegal ONU.
Referring to shown in Figure 1, Fig. 1 has represented in the prior art that the register flow path of defined illegal ONU in IEEE 802.3 standards mainly may further comprise the steps:
Under the initial situation, ONU is in " waiting for (Wait) " state, waits for that OLT finds gating (Discovery Gate) message to all one of ONU broadcasting, opens ONU and finds window, as step S1.
Control under the control of indicator (MACR) at the MAC of ONU higher level protocol suite, ONU enters " registration (Registering) " state, as step S2; And in new discovery window, send " register requirement (Register_REQ) " message to OLT, and as step S3, comprising its mac address information in this message, ONU waits for that OLT sends " registration Register " message then:
If judging ONU is illegal ONU, OLT will send " refusal registration (NackRegister) " message, and the flag field of this message is Nack and not in the discovery window; ONU controls the high level of Indication message (MACI) notification protocol stack with unaccepted incident by MAC, and enters " registration is rejected " state, as step S6 after receiving this " refusal registration (Nack Register) " message; (UCT UnConditionalTransfer) to " waiting for (Wait) " state of step S1, restarts registration process, as step S11 in unconditional branch then;
If ONU is that another finds that window arrives at " register requirement (Register_Request) " state, then ONU enters " retry (RETRY) " state, as step S7, and to the high level transmission MAC of its protocol stack control Indication message (MACI) message, ONU gets back to unconditional branch " register requirement (Register_REQ) " state then, as step S10;
If receiving the MAC control indicator of sending from its higher level protocol suite (MACR) when " register requirement (Register_Request) " state, ONU make it separate registration, then ONU transfers to " waiting for (Wait) " state, restart registration process, as step S4.
If ONU receives that when " register requirement (Register_Request) " state " registration (the Register) " message sent from OLT and the Flag value of this message are " ACK ", then ONU transfers to " queued for log-on result (Register_Pending) " state, as step S5;
If having received from the MAC control indicator (MACR) of higher level protocol suite and the status field value in this message, ONU is " ACK " under " queued for log-on result (Register_Pending) " state, then ONU enters into " confirming registration (Register_Ack) " state, as step S8; ONU unconditional branch is to " (Registered) succeeds in registration " state, as step S12 then;
If having received from the MAC control indicator (MACR) of higher level protocol suite and the status field value in this message, ONU is " NACK " under " queued for log-on result (Register_Pending) " state, then ONU enters into " denying registration (NACK) " state, as step S9; ONU to " waiting for (Wait) " state, restarts registration process, as step S13 with unconditional branch then.
When ONU is in " (Registered) succeeds in registration " state,, then transfer to " queued for log-on result (Register_Pending) " state, as step S14 if receive " re-registering " message that OLT sends; If receive " separating registration (Deregister) " message that OLT sends, then transfer to " long-range separate registration (RemoteDeregister) " state, as step S15, ONU unconditional branch immediately is to " waiting for (Wait) " state then, restart registration process, as step S17; If ONU receives the status field value from MAC control indicator (MACR) message of higher level protocol suite and this message and is " Deregister ", then ONU enters " registration (Local Deregister) is separated in this locality " state, as step S16, ONU unconditional branch immediately is to " (Registered) succeeds in registration " state, as step S18 then.
ONU is under any state except step S1 " wait (Wait) " state, if receive MPCP timer expiry signal, then enter " MPCP timer expiry (Watchdog Timeout) " state, unconditional branch is to step S1 " wait (Wait) " state then, restart registration process, as step S19.
In the prior art, after ONU receives Nack Register message from OLT, can enter the state of re-registering at once, this can cause constantly re-registering of illegal ONU to take network bandwidth resources, constantly attempt registering the negative effect that brings to system in order to reduce ONU, the convenience of considering engineering simultaneously and safeguarding is still given this ONU the chance of certain trial registration, therefore need the registration process of existing ONU be further improved.
Summary of the invention
In view of this, the present invention proposes a kind of register method of optical network unit, reduces continuous, the high-frequency trial of illegal ONU and registers the burden of bringing to system.
Register method based on above-mentioned purpose optical network unit provided by the invention comprises: after OLT sends login request message, if receive refusal registration message from OLT, then send a notification message to higher level protocol suite in the ONU registration process; After the ONU higher level protocol suite is being received this notification message, start a timer; When timer surpassed set point, ONU entered into wait state, restarts new register flow path.
The described ONU higher level protocol suite of this method starts described timer by MAC control Indication message.
After the described ONU of this method receives the refusal registration message, notify described higher level protocol suite by MAC control Indication message.
The time-out time of timer shown in this method is to enter the ONU time delay of registration process next time.
It is unconditional branch that the described ONU of this method enters into the wait state process.
This method is consistent with flow process among the IEEE802.3 for the register flow path of legal ONU.
From above as can be seen, the register method of the optical network unit that the present invention proposes, after the ONU higher level protocol suite is being received this MAC control Indication message, start a timer, make in the ONU registration process, increased the mechanism of mourning in silence of illegal ONU, reduced continuous, the high-frequency trial of illegal ONU and registered the negative effect that brings to system, constantly registration can increase the expense in the system, reduces the bandwidth usage efficient of system.Taking into account system construction simultaneously of the present invention and the facility of safeguarding are still given this ONU the chance of certain trial registration.The present invention can with existing IEEE 802.3 operating suchs, do not need additionally to define other message, thereby can not increase the weight of load according to the system of IEEE 802.3 standard operations.
