Description
Technical field
The present invention relates to the communications field, more particularly to a kind of control method and device of DCN passages.
Background technology
At present, in Packet Transport Network（Packet Transport Network, PTN）In, typically by positioned at convergence-level
NM server be pointed to each PTN network elements of Access Layer and be managed, as shown in Figure 1.
Fig. 1 is PTN networking structures schematic diagram of the prior art, and 10 PTN network elements, respectively PTN nets are had in Fig. 1
Member 1 ~ 10, this 10 network elements are located at the Access Layer of PTN network.NM server is located at the convergence-level of PTN network.Primary gateway 1,
Primary gateway 2, standby gateway are located at Access Layer and the intersection of convergence-level, for being that NM server and each PTN network elements turn
Send out data communication network（Data Communication Network, DCN）Message.
In Fig. 1, PTN network elements 1 ~ 5 have been mounted under primary gateway 1, wherein, the PTN network elements 1 ~ 3 being linked in sequence constitute one
Chain is accessed, or for access ring, the PTN network elements 4,5 being linked in sequence also constitute an access chain.It is articulated under the primary gateway 1
PTN network elements 1 ~ 5 and primary gateway 1 constitute a DCN domain, or for management domain, be designated as the first DCN domains.Primary gateway 1 is used
In all PTN network elements in the case where being articulated to its own（PTN network elements 1 ~ 5 in first DCN domains of primary gateway 1 itself connection）With
DCN message is forwarded between the NM server of convergence-level, NM server is managed PTN network elements 1 ~ 5 by primary gateway 1.
Similar, PTN network elements 6 ~ 10 have been mounted under primary gateway 2, wherein, PTN network elements 6 ~ 8 constitute an access chain, PTN
Network element 9,10 constitutes an access chain.The PTN network elements 6 ~ 10 and primary gateway 2 being articulated under primary gateway 2 constitute a DCN
Domain, is designated as the 2nd DCN domains.Primary gateway 2 is used for all PTN network elements in the case where being articulated to its own（Primary gateway 2 itself is connected
The 2nd DCN domains in PTN network elements 6 ~ 10）DCN message is forwarded between the NM server of convergence-level, leads to NM server
Cross the primary management PTN of gateway 2 network elements 6 ~ 10.
And the standby gateway being connected with above-mentioned two DCN domains is then used for when primary gateway 1 breaks down simultaneously, instead of master
It is that PTN network elements 1 ~ 5 forward DCN message with NM server with gateway 1, or when primary gateway 2 breaks down, instead of primary
Gateway 2 is that PTN network elements 6 ~ 10 forward DCN message with NM server.
However, either primary gateway or standby gateway, the disposal ability of its own is limited, therefore, it is possible to mount
The quantity of PTN network elements under primary gateway or standby gateway is also limited, for example, primary gateway or standby can be articulated in
The quantity of PTN network elements under gateway is at most 64.
And in PTN network as shown in Figure 1, standby gateway is connected with the first DCN domains and the 2nd DCN domains simultaneously, if
The quantity of the PTN network elements included in the two DCN domains is more, for example, be 50, then in order to avoid mounting under standby gateway
The quantity of PTN network elements exceed its maximum mounting NE quantity 64, be typically by standby gateway to the first DCN domains in the prior art
DCN passages close, or the DCN passages of standby gateway to the 2nd DCN domains are closed, that is, only opening standby gateway to one
The DCN passages in individual DCN domains.
But, when a DCN passage in standby gateway is only opened using method of the prior art, if in closing
Primary gateway in the DCN domains that the DCN passages of state are connected breaks down, then occurs without any gateway can be to be somebody's turn to do
PTN network elements in DCN domains forward the situation of DCN message, and now, all PTN network elements in the DCN domains will take off pipe.
For example, in the PTN network shown in Fig. 1, only opening standby gateway to the DCN passages in the first DCN domains, closing standby
Gateway, can be due to standby gateway to the 2nd DCN if now primary gateway 2 breaks down to the DCN passages in the 2nd DCN domains
The DCN passages in domain have been closed and all PTN network elements in the 2nd DCN domains have occurred（PTN network elements 6 ~ 10）The situation of de- pipe,
That is, NM server can not manage all PTN network elements in the 2nd DCN domains.
Now, in the prior art can only be manually be positioned to de- pipe PTN network elements, and opens standby by NM server
With the DCN passages that the 2nd DCN domains are connected in gateway, to recover the management to PTN network elements in the 2nd DCN domains, this may result in the
The time of the de- pipe of PTN network elements is longer in two DCN domains, and the speed of recovery management is slower.

The embodiment of the present invention is described in detail with reference to Figure of description.
Fig. 2 is DCN passages control process provided in an embodiment of the present invention, specifically includes following steps：
S201：Standby gateway is detected to the primary gateway in each DCN domains of connection.
In embodiments of the present invention, visited by the primary gateway in each DCN domains to connection of standby gateway active
Survey, whether the primary gateway in each DCN domains to detect connection breaks down.Specific method can be：Standby gateway pin
To the primary gateway in each DCN domains of connection, based on the annexation of the primary gateway in convergence-level, according to setting
Time interval, sends detection inquiry message, and judge whether to receive the master in the time span of setting to the primary gateway
The probe response message returned with gateway, if, it is determined that detect the primary gateway and do not break down, otherwise, it determines detection
Broken down to the primary gateway.
Wherein, the detection inquiry message that standby gateway is sent to primary gateway can be specifically pre-defined
Can carry the identification information of the standby gateway in IFONLINE_MSG message, the IFONLINE_MSG message, be sent to should
The identification information of primary gateway, message type information.The probe response message that primary gateway is returned to standby gateway specifically can be with
It is that can carry the identification information of the primary gateway in pre-defined ONLINE_MAG message, the ONLINE_MAG message, wait to return
The identification information and message type information for the standby gateway being back to.
For example, still being illustrated by taking the PTN network shown in Fig. 1 as an example, due to standby gateway and primary gateway 1 and primary net
Close 2 has direct-connected relation in convergence-level, therefore, and standby gateway is directed to the first DCN domains（Including PTN network elements 1 ~ 5 and primary gateway
1）In primary gateway 1, based on the direct-connected relation of the primary gateway 1 in convergence-level, at set time intervals to master
IFONLINE_MSG message is sent with gateway 1, it is similar, for the 2nd DCN domains（Including PTN network elements 6 ~ 10 and primary gateway
2）In primary gateway 2, based on the direct-connected relation of the primary gateway 2 in convergence-level, also at set time intervals to
Primary gateway 2 sends IFONLINE_MSG message.
For primary gateway 1, if primary gateway 1 does not break down, primary gateway 1 receives detection inquiry and disappeared
Breath（IFONLINE_MSG message）Afterwards, ONLINE_MAG message can be returned to standby gateway（Probe response message）, so that standby
Gateway knows that the primary gateway 1 does not break down, if primary gateway 1 breaks down, and primary gateway 1 would not be to standby net
Close and return to ONLINE_MAG message.Therefore, standby gateway can decide whether to receive primary net in the time span of setting
The 1 ONLINE_MAG message returned is closed, if, it is determined that primary gateway 1 does not break down, otherwise, it determines primary gateway 1 occurs
Failure.
Similar, for primary gateway 2, standby gateway equally judges whether to receive in the time span of setting primary
The ONLINE_MAG message that gateway 2 is returned, if, it is determined that primary gateway 2 does not break down, otherwise, it determines primary gateway 2 goes out
Existing failure.
S202：When the primary gateway at least one the DCN domain for detecting connection breaks down, standby gateway is opened certainly
The DCN passages in the DCN domains where body to the primary gateway broken down, close standby gateway itself primary to what is do not broken down
The DCN passages in the DCN domains where gateway.
In embodiments of the present invention, primary gateway of the standby gateway at least one the DCN domain for detecting its connection goes out
During existing failure, illustrate that all PTN network elements in the DCN domains where the primary gateway broken down take off and manage, now need by this
Standby gateway is the PTN network elements forwarding DCN message in the DCN domains where the primary gateway of failure, so that positioned at convergence-level
NM server can pass through the standby gateway continue manage PTN network elements.Therefore, standby gateway opens itself to failure
Primary gateway where DCN domains DCN passages, turn for the PTN network elements in the DCN domains where the primary gateway of the failure
DCN message is sent out, to recover management of the NM server to PTN network elements in the DCN domains.
Also, for the primary gateway not broken down detected, illustrate the primary gateway institute do not broken down
DCN domains in all PTN network elements do not take off pipe, without where the primary gateway that is not broken down for this by the standby gateway
DCN domains in PTN network elements forwarding DCN message.Therefore, standby gateway closes itself to the primary gateway place do not broken down
DCN domains DCN passages, to reduce the quantity of PTN network element of the carry under the standby gateway as far as possible, reduce the negative of standby gateway
Carry.
, can if primary gateway of the standby gateway in all DCN domains for detecting its connection does not break down
To open itself to the DCN passages in all DCN domains connected, it is of course also possible to close itself to all DCN domains connected
DCN passages.
Continue to use the example above, it is assumed that standby gateway detects primary gateway 1 and broken down, detect primary gateway 2 and do not go out
Existing failure, then can open the standby gateway itself to the DCN passages in the first DCN domains at the primary place of gateway 1, close this standby
The DCN passages in the 2nd DCN domains where gateway itself to primary gateway 2.If standby gateway detects primary gateway 1 and primary
Gateway 2 does not break down, then can open itself simultaneously to the DCN passages in the first DCN domains and the 2nd DCN domains, can also be same
When close itself to the DCN passages in the first DCN domains and the 2nd DCN domains.
By the above method, standby gateway can automatically control itself according to the result of detection to each primary gateway
DCN passages to each DCN domains are turned on and off, without PTN network elements by the way that de- pipe is positioned manually, without manually passing through net
DCN passages of pipe server controls standby gateway, therefore effectively shorten the de- pipe time of de- pipe PTN network elements, are improved pair
The speed of de- pipe PTN network element recovery managements.
Preferably, the quantity in order to further reduce PTN network element of the carry under the standby gateway, when standby gateway detection
When being broken down to the primary gateway in two or more DCN domains of connection, that is, detecting the primary net of failure
When closing in the presence of two or more, standby gateway can be set according in advance for the primary gateway in each DCN domains of connection
Priority, the primary gateway of highest priority is determined in the primary gateway of failure, and standby gateway itself is opened extremely
The DCN passages in the DCN domains where the primary gateway of the highest priority determined, close standby gateway itself to other DCN domains
DCN passages.
For example, standby gateway is connected with four DCN domains altogether, the primary gateway in this four DCN domains is primary gateway 1 respectively
~ 4, it is assumed that be followed successively by advance for the priority order from high to low of this four primary gateways settings：Primary gateway 1, primary net
Close 2, primary gateway 3, primary gateway 4, then it is standby when standby gateway detects primary gateway 2 and the failure of primary gateway 3
Gateway is according to the priority for being in advance this four primary gateway settings, it is determined that highest priority in the primary gateway broken down
Primary gateway is primary gateway 2, therefore, and standby gateway opens itself to the DCN passages in the DCN domains where primary gateway 2, closes
Itself to other DCN domains DCN passages, that is, closing itself to where primary gateway 1, primary gateway 3, primary gateway 4
The DCN passages in DCN domains.
Further, in order to make the quantity of the PTN network elements of standby gateway carry be hung no more than the maximum of the standby gateway
On the premise of connecing NE quantity, the utilization rate of standby gateway is improved as far as possible, in embodiments of the present invention, when standby gateway is detected
, can also be according to each DCN in advance for connection when primary gateway in two or more DCN domains of connection breaks down
The priority of primary gateway setting in domain, according to the order of priority from high to low, selects the primary net broken down successively
Close, wherein, the quantity sum of the PTN network elements included in the DCN domains where each primary gateway of selection is not more than the standby gateway
Maximum mounting NE quantity, and open the DCN in the DCN domains where standby gateway itself to each primary gateway selected and lead to
Road, closes standby gateway itself to the DCN passages in other DCN domains.
For example, standby gateway is connected with four DCN domains altogether, respectively the first DCN domains, the 2nd DCN domains, the 3rd DCN domains, the
Primary gateway in four DCN domains, this four DCN domains is primary gateway 1 ~ 4 respectively.
Assuming that the quantity of the PTN network elements included in this four DCN domains is 30, the maximum mounting NE No. of standby gateway
Measure as 64, be followed successively by advance for the priority order from high to low of this four primary gateways settings：It is primary gateway 1, primary
Gateway 2, primary gateway 3, primary gateway 4.
When standby gateway detects primary gateway 1, primary gateway 2 and the failure of primary gateway 4, then according to priority
Order from high to low, selects these three the primary gateways broken down successively.When selecting primary gateway 1, due to primary net
The quantity for the PTN network elements that the first DCN domains where closing 1 are included is 30, less than the maximum mounting NE quantity of the standby gateway
64, therefore continue to select primary gateway 2 in order.It has selected after primary gateway 2, the first DCN domains and master where primary gateway 1
The PTN NE quantities sum included with the 2nd DCN domains where gateway 2 is 60, still less than the maximum mounting of the standby gateway
NE quantity 64, therefore continue to select primary gateway 4 in order.But, it have selected after primary gateway 4, where primary gateway 1
The PTN NE No.s included in the 4th DCN domains where the 2nd DCN domains, primary gateway 4 where first DCN domains, primary gateway 2
It is 90 to measure sum, has exceeded the maximum mounting NE quantity 64 of standby gateway, therefore, standby gateway only selects primary gateway 1
With primary gateway 2, primary gateway 4 is not selected.Follow-up, standby gateway then opens itself to the place of primary gateway 1 selected
The first DCN domains DCN passages, open itself to the DCN passages in the 2nd DCN domains where the primary gateway 2 selected, close
Itself is to other DCN domains（3rd DCN domains and the 4th DCN domains）DCN passages.
In addition, in embodiments of the present invention, in order to ensure standard that management server is managed each DCN domains by standby gateway
DCN ports in the DCN passages for connecting each DCN domains can also be divided in same port set by true property, standby gateway, and be prohibited
DCN message is only interacted between each DCN ports in the port set.That is, standby gateway is for the DCN ports in each DCN passages,
DCN message is only forwarded between DCN ports and NM server, without interaction DCN message between each DCN ports of permission.
Continuation is illustrated by taking Fig. 1 as an example, it is assumed that the DCN port-for-ports that standby gateway is connected with PTN network elements 5 in Fig. 1
1st, the DCN port-for-ports 2 being connected with PTN network elements 3, namely standby gateway connect the DCN ends in the DCN passages in the first DCN domains
Mouth is port 1 and port 2；DCN port-for-ports 3 that standby gateway is connected with PTN network elements 6, the DCN ends being connected with PTN network elements 9
Mouthful be port 4, namely standby gateway connect the 2nd DCN domains DCN passages in DCN port-for-ports 3 and port 4.It is then standby
Port 1, port 2, port 3, port 4 can be divided in same port set by gateway, and forbid each DCN ends in the port set
Interaction DCN message between mouthful, that is, forbid interaction DCN message between port 1, port 2, port 3, port 4.
