Embodiment
The formation of RPR loop and professional configuration:
Fig. 2 is a RPR networking schematic diagram.The typical Cheng Huantu of RPR loop is as shown in the figure: website S1 (the website MAC Address is 0x000000000001), S2 (the website MAC Address is 0x000000000002), S3 (the website MAC Address is 0x000000000003), S4 (the website MAC Address is 0x000000000004) form the closed loop of a 1.25G, logical professional between website S1 and the website S3, website S1 configuration reserved bandwidth is 200M, limiting bandwidth is the A service of 300M, it is 200M that website S3 also disposes reserved bandwidth, and limiting bandwidth is the A service of 300M.
Fig. 1 is the graphical flow chart of steps that dynamically shows the RPR topology of the present invention, comprises the steps:
Step 101: determine the required information of dynamic display network topology.
The RPR network topology of drawing need know the geographical position of each website, MAC Address, guard mode, from by the distance of query point; For making things convenient for the inquiry business state, also need type of service, the bandwidth of knowing that each website disposes; For guaranteeing the version consistency, also need to provide soft, the hardware version information of each website.
Step 102: the transmission of network topological information and exchange.
The state information of website is transmitted by TP (transaction) frame and ATD (asynchronous time-division multiplex) the frame mode by standard code, geographical position, version and partial service type information are not to stipulate in the standard, these information are appended to as " customized information " in the payload of ATD frame and transmit, each website is received behind the ATD frame in the topological database of these information being deposited separately.
The foundation of step 103: initial topology figure.
Fig. 3 is an initial condition topology schematic diagram.Inquiry mode is adopted in the foundation of initial topology figure.Each website will be realized the inquiry of network topology, because each website is all safeguarded the topological database of portion oneself, all network topological informations can obtain from topological database, protocol requirement is deferred in the definition of topological database fully, realizes the inquiry of RPR network topology by increasing querying command.The information that the website of being inquired about reports is sequenced preface according to each website distance by query point distance from the near to the remote; the information of the website of being inquired about is as article one record in the reporting information; webmaster writes down each website that draws one by one according to these, and indicates different guard modes with different colors.During the unprotect state, link to each other with blue solid lines between each website, each SPAN (switching port analyzer) port is represented with green, exists guard mode then to link to each other with neighbors with red dotted line as if current website, and indicates the current guard mode of span port with color.
Step 104: the dynamically updating of topological diagram.
Fig. 4 is the RPR network topology schematic diagram after upgrading.The dynamically updating to take the initiative of topological diagram reports mode, and following situation will trigger the automatic renewal of topology:
1, each website detects the configuration change of this point, disposes Forced Switch, Manual Switch as the change of jumbo attribute, protected mode change, user.
2, the our station point detects the alarm generation or disappears, as the generation and the disappearance of Signal Fail, Signal Degrade.
3, the our station point detects that neighbors lost efficacy or the guard mode of this website is seized.
Above situation occurs, this website just reports one " topology change " notice message to give webmaster, and webmaster is sent out querying command to this website then, obtains the latest network topology from veneer, and upgrades the interface topological diagram.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all contained by claim of the present invention.
