In the face of a large number of high-density optical cables in a data center, a data center administrator needs to deal with the following different challenges, which not only affect the work efficiency of the data center administrator and increase the operation cost, but also may cause network downtime and huge economic loss.

Therefore, how to better manage cables is an important issue facing IDC data centers. At present, IDC cables are mainly managed by the following means: 1. recording paper: and recording the conditions of the rack, the cable and the client through the excel, and manually updating the rack, the cable and the client when the service is opened and the daily operation and maintenance are carried out. 2. And (3) fault driving: and after the cable fault occurs, analyzing corresponding cable routing information and making an adjustment measure. 3.

Step S102: resource association:

and associating the resources to form a multidimensional associated view of the resources, the clients and the services, as shown in fig. 2.

Floor-machine room: the floor contains a plurality of computer rooms, and the computer room must belong to a certain floor.

Machine room-floor: the machine room comprises a plurality of floors, and the floors belong to a certain machine room. For floors other than machine rooms, such as hallways, no management is done as there is no involvement of rack/ODF racks.

floor-rack/ODF/DDF rack: the floor is in a many-to-many relationship with the racks/ODF/DDF racks, and one floor can accommodate multiple racks, as can multiple floors.

Rack/ODF Rack-ODF/DDF terminals: the rack comprises a plurality of ODF/DDF modules and a plurality of ODF/DDF terminals, and the ODF/DDF terminals must belong to a certain rack/ODF/DDF rack.

The circuit comprises: the circuit contains the originating and terminating subscriber equipment, the DDF terminals (which may be multiple), and the in-building cables (which may be multiple segments) to which they are connected.

Step S103: and (3) analyzing resources to form a unified view based on the machine room and the cables:

based on the resource unified model established in S101 and the resource association model established in S102, the IDC can be globally analyzed to form a unified view, and early warning is performed on resources. As in fig. 4, the following information is included:

1) machine room rack condition: a total number representing the total number of racks in the room; used, indicates the number of racks used in the room. Through the machine room-floor, the floors in the machine room can be obtained; through the floor-racks, it is possible to obtain that those racks are placed on the floor; thus, the association of machine room-floor-rack can obtain the total number of racks in the machine room. Through customer-orders, it is possible to get which orders the customer has; through the order-racks, it is possible to obtain the racks contained in the order; thus, the customer-order-rack association can obtain the racks occupied by the customer in each machine room, thereby counting the number of used racks in a certain machine room.

2) Optical cable in the machine room: the number represents the number of the connection optical cables between the machine rooms; a total number representing a total number of optical fibers in the optical cable; used, indicates the number of fibers used. According to the initial/termination ODF terminal information of the optical fiber in the building, the number information of the optical cable sections corresponding to the optical fiber in the building can be obtained through the optical fiber-jumping connection/fusion connection-optical fiber-optical cable sections in the building. The total number of fibers can be obtained by summing the cores in each cable segment. Through the incidence relation of the optical path and the optical fiber in the building, the used quantity of the fiber cores can be obtained.

3) Cable between computer lab: the number represents the number of the connecting cables between the machine rooms; a total number representing a total number of cables in the cable; used, indicates the number of cables used. According to the initial/termination DDF terminal information of the cable in the building, the quantity information of the cable sections corresponding to the cable can be obtained through cable-jumping/welding-cable sections in the building. By summing up the cables in the individual cable sections, the total number of cables can be obtained. Through the circuit-cable association, it is possible to obtain how many of these cables have been used.

4) Machine room layout: the machine room is automatically local. The machine rooms on the same floor can be arranged in the same row through the relationship between the floor and the machine rooms; the machine rooms can be arranged on the same horizontal axis in sequence according to the arrangement of the machine room numbers from small to large, such as D401, D402, D403 and D404; meanwhile, the machine rooms with the same machine room number and different floors can be arranged on the same longitudinal axis.

5) Machine room cable connection: connected by a fold line. Connecting lines of the machine rooms are connected through broken lines according to the design drawing requirements of the communication machine room; when the connection lines of the machine rooms are overlapped, the connection lines are displayed in a staggered mode at certain intervals through an algorithm.

6) Resource early warning: including the early warning index, the early warning value and the color. The early warning indexes are early warning indexes to be analyzed and comprise machine room rack utilization rate, optical cable and optical fiber utilization rate, cable utilization rate, optical cable redundancy and cable redundancy;

the utilization rate of the machine room frames is obtained by using the used quantity/total number obtained by calculation in the step 1), and an early warning value and an early warning color are set, wherein if the used quantity/total number is less than 80% of blue, 80% -90% of orange and more than 90% of red, the early warning color is set on the number of the frames displayed in the machine room;

the utilization rate of optical fibers of the optical cable is obtained by the total number of used fiber cores/fiber cores obtained by calculation in the step 2), an early warning value and an early warning color are set, if the light is blue at the rate of 80 percent, orange at the rate of 80-90 percent and red at the rate of 90 percent, the capacity expansion of the optical cable is required to be carried out as soon as possible in the later period, and the early warning color is set on the optical cable connecting line of the machine room;

the cable utilization rate, 3) the number of idle cables in the machine room/the total number of cables obtains the cable redundancy rate, an early warning value and an early warning color are set, if the number of idle cables in the machine room is less than 80% of blue, the number of idle cables in the machine room is 80% -90% of orange, and the number of idle cables in the machine room is more than 90% of red, cable expansion needs to be carried out as soon as possible in the later period, and the early warning color is set on a connecting line of the machine room;

optical cable redundancy, 2) in the machine room optical cable quantity >1 is blue, 1 is orange, which indicates that the machine room can not realize optical cable main use/standby, needs to be expanded as soon as possible, 0 is red, which indicates that no optical cable exists in the machine room, and red warning is given.

And 3) the number of idle cables in the machine room is more than 2 and is blue, the number of idle cables is equal to 2 and is orange, the number of idle cables is equal to 1 or 0 and is red, and the early warning color is set on the machine room connecting line.

Step S104: and abstracting the scheduling rule according to the operation and maintenance scene.

In daily scheduling, in order to ensure the line quality and reduce the routing loss, service scheduling needs to be performed according to a certain rule. The following scheduling scenarios are included:

1) the number of transfer points is minimum: the switching points are the most likely to cause breakpoint faults, and the fewer the switching points ODF/DDF passed by the scheduling route, the better.

2) The shortest route: the length of the optical fiber/cable through which the dispatch route passes is the shortest, usually short, i.e., there is little probability of a failure occurring.

3) And (3) specifying a routing machine room: the scheduled route must pass through a certain designated machine room, usually an MMR (meetmeroom) machine room for the switching of the optical/electrical cables of each machine room, so that the MMR machine room is often set as a designated routing node during scheduling.

4) Cable redundancy selection: when the scheduled route has been determined according to the above rules, there will typically be multiple optical/electrical cables available for selection (the routes are identical). Cable redundancy selection is mainly used to set: the cable can not be selected without redundancy, namely the optical cable redundancy early warning/the cable redundancy early warning can not be selected; cable fiber usage/cable usage > 80% is not selectable, even if rate warning is not selectable.

5) Cable sequence selection of cables: this rule is only applicable to optical path scheduling and does not apply to circuit (cable) scheduling. After the selection is completed according to the four rules, multiple optical fibers of the same optical cable can be selected for a certain section of scheduling route (the route is completely the same, and the optical cables are also the same). The cable sequence selection rule is mainly used for setting: the core order is minimum: the fiber core with the minimum fiber core sequence number in the same optical cable, for example, 4 fiber cores are scheduled, and the 4 fiber cores with the minimum fiber core sequence in the optical cable are found, wherein the fiber core sequence can be discontinuous; the continuous core order is minimum: the fiber cores in the same optical cable have the continuous minimum numbered fiber cores, and the core sequence must be continuous; the continuous core order is maximum: the fiber cores in the same optical cable have the maximum serial numbers, and the core sequence must be continuous.

Step S105: the scheduling rules are encapsulated and set priorities.

And (5) packaging the 5 rules of the S104, selecting a plurality of scheduling rules for packaging and setting priorities, and adopting an AND logic operation rule among the packaging rules on the basis of the priorities. For a rule requiring parameter setting, "routing node designated": the appointed machine room needs to be selected, and the cable sequence selection: it is necessary to select one of "minimum core order", "minimum continuous core order", and "maximum continuous core order".

Step S106: and performing automatic scheduling based on the packaged scheduling rule with the set priority to generate a scheduling result.

And searching the machine rooms where the start end and the stop end are located according to the start end and the stop end of the service requirement, and automatically scheduling the route according to the rule based on the preset rule to search the cable route meeting the requirement. The scheduling result is directly shown on the route in fig. 4.

Step S107: and if the scheduling result is not satisfactory, such as too many transfer points (>3) passed by the cable route generated by scheduling or route repetition, the rule can be modified, and the automatic scheduling is carried out again.

When the result of the scheduling is not satisfactory, the scheduling rule can be modified, and the system carries out rescheduling according to the newly set rule.

In fig. 4, a new designated routing node may be selected, the system automatically reschedules, and the scheduling result is directly shown in fig. 4.

Step S108: and implementing according to the scheduling result, and updating the connection condition, the use condition and the service condition of the resources.

And generating a construction order according to a scheduling result, wherein the construction order comprises jumper connection information, cable routing information and start/stop end information, carrying out field construction by constructors, carrying out construction backfill after the construction is finished, updating the state of resources in time and finishing the closed-loop circulation of services.

Example 2

The invention covers the automatic scheduling of routes such as light paths, circuits and the like, and the example shows the visual automatic scheduling of the light paths.

Fig. 5 is a schematic flow chart of visual automatic scheduling of an IDC room optical path according to a second embodiment of the present invention. FIG. 6 is an example of automatic scheduling, which is needed to automatically schedule an end-to-end dual fiber route from ODF-A-001/002 to ODF-Z-001/002, based on the following rules (rules are ordered by priority):

1) and (3) specifying a routing machine room: d is the machine room that must be passed through.

2) Minimum number of transfer points

3) Shortest route

4) And (3) optical cable redundancy selection: the cables must be redundant and the occupancy cannot exceed 80%.

5) Cable sequence selection: and selecting a continuous core sequence to be minimum in the cable sequence.

The method comprises the following specific steps:

s2001: and uniformly modeling resources, including floors, machine rooms, floors, racks, DDF racks, ODF racks, U bits, optical cables/cables, optical cable sections/optical fibers, optical paths/circuits, orders, work orders, clients and the like. The machine room A (DH304)/B1/B2/C1/C2/D/E1/E2/E3/E4/Z, the optical cable L1/L2, ODF-A (3F/DH304/DD01-ODF-1), ODF-Z and the like in the example are modeled and managed in the system.

S2002: and (4) modeling by a rule base, wherein the rules such as minimum switching points, shortest route, redundant selection of optical cables, sequential selection of cables and the like are modeled and managed in the system.

S2003: rule encapsulation, setting the starting end of a route as 3F/DH304/DD01-ODF-1-001/002 and the terminating end as ODF-Z-001/002, designating a route machine room as D, and automatically scheduling rules according to the priority as follows: the number of transfer points is the minimum, the route is the shortest, the optical cable redundancy selection and the cable sequence selection are the minimum continuous core sequence.

S2004: fig. 7A and 7B are schematic diagrams illustrating operations of start and end terminals in visual scheduling, and an ODF terminal to be scheduled is selected from a machine room plan view. The device where the terminal is located is obtained as 3F/DH304/DD01-ODF-1 and ODF-Z through the starting terminal 3F/DH304/DD01-ODF-1-001/002 and the terminating terminal ODF-Z-001/002.

S2005: the machine rooms where the 3F/DH304/DD01-ODF-1 and the ODF-Z are obtained are machine rooms DH304 and Z respectively.

S2006: and acquiring a designated router room D. And carrying out automatic scheduling among the DH304-D according to rules, carrying out automatic scheduling among the D-Z according to the rules, and completing all scheduling to form the end-to-end route of the DH 304-D-Z.

Route auto-search is performed between the DH 304-D. The presence of DH304-L1 (Cable) -D route, DH304-L2 (Cable) -D route, DH304-B1-C1-D route was found.

And performing automatic route searching between D-Z. D-M1 (fiber optic cable) -E1 (machine room) -Z, D-M2 (fiber optic cable) -E1 (machine room) -Z, D-M3 (fiber optic cable) -E2 (machine room) -Z routing was found to exist.

S2007: according to the transfer point minimum rule.

In the route of DH304-D, DH304-L1-D route and DH304-L2-D route are direct routes, there is no transfer point, DH304-B1-C1-D route has two transfer points, therefore DH304-B1-C1-D is not the best route. Three routes in Z-D are all two transit points and therefore all pass the rule.

S2008: according to the shortest route rule. In the route of DH304-D, the route length L1 of DH304-L1-D is 500 meters, and the route length L2 of DH304-L2-D is 800 meters, so the DH304-L1-D route is selected. Of the routes of D-Z, all three are 600 meters in length and therefore all pass this rule.

S2009: and selecting rules according to the cable redundancy. The cables that are routed must be redundant, and the DH304-D routes are routed so that the rule and subsequent rules are not used because one route has been uniquely identified according to the rule priority. In the D-Z route, M1 and M2 optical cables are optical cables between D-E1 rooms, redundancy exists, that is, switching under a fault condition can be realized, and the D-M3-E2-Z route is not the optimal route because only one M3 optical cable between D-E2 cannot realize redundancy backup.

Further analysis shows that the optical cable occupancy rate of the M1 optical cable is 88%, and the requirement that the optical cable occupancy rate cannot exceed 80% is not met. Thus D-M1-E1-Z failed the rule and D-M2-E1-Z was the best route.
