Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a system for managing service resources.
Background
In the transmission device, a global system port (SysPort) is generally used to represent a channel of a single disk chip, so as to implement control and management of various services. The existing service resource management scheme performs static allocation on the SysPort resource, for example, the SysPort resource is 32K, and for a single disk with jericho chips and arad chips, 64 slots each have 512 channels (channels) on average. Due to the fact that the capacity of a single disk is increasing, for example, a single disk with double jericho chips and double G5 theoretically supports ODU0 cross (800 channels) of 1TG, due to the limitation of SysPort resources, if SysPort resources are allocated to each slot on average, each slot only supports ODU0 cross (480 channels) of 600G, and the access of a large-capacity single disk cannot be met. With the future increase of the capacity of a single disk and the difference of the types of the capacity of the single disk in each slot, a more effective service resource management scheme is urgently needed.

On the basis of the technical scheme, the method further comprises the following steps: and the main control disk adaptation layer calculates to obtain a channel number according to the SysPort ID, creates a single disk identifier Fapid and a single disk port number FapPort according to the single disk capacity type and the channel number, and sends the single disk identifier Fapid and the single disk port number FapPort to a corresponding single disk.
On the basis of the technical scheme, according to the capacity type of the single disk, dividing all the channel numbers of the single disk into n levels from small to large, wherein in the ith level:
160 < i > stage the total number of said channel numbers < 200,

the SysPort ID ═ (slot number-1) × 1000+ the backplane port number;
the channel number is (SysPort ID-1)% 1000+ 1.
On the basis of the technical scheme, after receiving the deletion instruction of the channel information, the main control panel adaptation layer finds and deletes the keywords corresponding to the channel information in a keyword list, wherein the keyword list is used for storing the created keywords and the corresponding channel information.
On the basis of the technical scheme, the main control panel adaptation layer reports and issues the SysPort ID through a UDP message.

Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
A first embodiment of the present invention provides a method for managing service resources, which is used in a communication Network, for example, a Packet Optical Transport Network (POTN) Network, a Packet Transport Network (PTN) Network, and an Optical Transport Network (OTN).
The service resource management method comprises the following steps: the main control disk adaptation layer receives the configuration information of the single disks in each slot position, assembles keywords according to the channel information in the configuration information, and creates a global system port number SysPortID based on the keywords and sends the global system port number SysPortID to the corresponding single disks, wherein the channel information, the keywords and the SysPortID have a one-to-one mapping relationship between each two.
Specifically, the single disk capacity types of the slots may be the same or different, for example, the single disk chip may be: 200G (Single ARAD) disks, 400G (Dual ARAD) disks, 400G (Single jericho plus Dual 4) disks, 500G (Single jericho plus Single G5) disks, and/or 1T (Dual jericho plus Dual G5) disks, the number of channels and corresponding SysPort IDs for each single disk is different due to the different types of capacities of the single disks, see Table one below:
table one: single disc capacity type
| Single disc chip | Channel |
| 200G (Single ARAD) disc | 1-160； |
| 400G (double ARAD) disc | 1-320 |
| 400G (Single jericho plus double 4) disc | 1-320 |
| 500G (Single jericho plus Single G5) disc | 1-400 |
| 1T (double jericho and double G5) disc | 1-800 |
Referring to fig. 1, the method for managing service resources includes the following steps:
s110, the main control disk adaptation layer receives the configuration information of the single disk on each slot position issued by the network management or the control plane, and identifies the channel information and the creation instruction in the configuration information.
S120, the main control disk adaptation layer searches keywords corresponding to the channel information in a pre-created keyword list.
Specifically, the Channel information includes a slot number, a port number, and a service Data identifier of the Channel, where the service Data identifier may include a service serial number and an Optical Channel Data Unit (ODUk) value sent by a network manager or a control plane.
S130, judging whether the keyword is found, if not, entering the step S140; if yes, the process is finished.
S140 assembles the keyword according to the channel information.
A first mapping relation exists between the channel information and the keywords, and the first mapping relation is as follows:
the format of the keyword is: slot number + port number + traffic data identifier,
for example, when the service data identifier is a service serial number and an ODUk value issued by a network manager or a control plane, the first byte number is 4, the service serial number is offset by a second byte number, the second byte number is 8, and the ODUk value is offset by 12 bytes relative to the slot number.

The configuration information sent by the network manager or the control plane further includes single-disk capacity information, where the single-disk capacity information includes a single-disk capacity Type, a total number of ports, and a Value range of a backplane port on each port, where the backplane ports correspond to the channels one to one, as shown in table two, each slot entry includes a slot number, a capacity Type, a number of ports, and a Value range of an initial backplane port number, and the single-disk capacity information in table two may be in the form of Type, Length, and Value (Type, Length, Value) TLV.
For the sake of distinguishing from the backplane port number redistributed by the following master control disk adaptation layer, the backplane port number issued by the network manager or the control plane is the initial backplane port number, and since the backplane ports are in one-to-one correspondence with the channels, the initial backplane port number is also in one-to-one correspondence with the channel information. The value range of the initial backboard port number is the initial backboard port number and the termination backboard port number.
Table two: single disc capacity information
In step S150, the one-to-one mapping relationship between the keywords and the SysPort ID is the second mapping relationship, and since the backplane port corresponds to the channel, the backplane port number corresponds to the channel information. Therefore, a one-to-one mapping relationship between the backplane port number and the key and between the backplane port number and the SysPort ID can be respectively established to obtain the second mapping relationship.
Specifically, the main control disk adaptation layer allocates a unique backplane port number to each backplane port of the single disk in sequence according to the total number of the ports and the value range of the backplane port on each port, and establishes a one-to-one mapping relationship between the keywords and the SysPort ID through the backplane port number, for example:
SysPort ID (slot number-1) 1000+ backplane port number.
The master control disk adaptation layer uniformly allocates and manages the SysPort ID of the global system port number according to the received configuration information of the single disk on each slot position, thereby not only realizing dynamic allocation of service resources and meeting the access of the single disks with various capacities, but also simplifying the process of issuing configuration information by the network manager and the control plane, and not influencing the management of the service resources even if the network manager and the control plane simultaneously carry out service configuration and the configuration information has resource conflict.
A second embodiment of the present invention provides a method for managing service resources, where on the basis of the first embodiment of the present invention, a master adapter layer calculates a channel number according to a SysPort ID, and creates a single-disk identifier FapId and a single-disk port number faport according to a single-disk capacity type and the channel number, and sends the single-disk identifier FapId and the single-disk port number faport to a corresponding single disk.
Channel number (SysPort ID-1)% 1000+ 1.
Dividing all channel numbers of a single disk into n stages in descending order according to the capacity type of the single disk, wherein in the ith stage:
160 < i > stage < total number of channel numbers < 200,
fapid ═ (slot number-1) × 4+ n-1,
FapPort is (lane number-1)% of the total number of lane numbers in the i-th stage,
wherein n is more than or equal to 1, and i is more than or equal to 1 and less than or equal to n.
The mapping formulas for Fapid and FapPort are shown in Table three:
table three: fapid and FapPort mapping tables
A third embodiment of the present invention provides a method for managing service resources, where on the basis of the second embodiment of the present invention, after receiving a deletion instruction of channel information, the master control panel adaptation layer finds and deletes a keyword corresponding to the channel information in a keyword list, where the keyword list is used to store the created keyword and the corresponding channel information.
The management method of the service resources comprises the following steps:
s210, the main control disk adaptation layer receives the configuration information of the single disk on each slot position issued by the network manager or the control plane, and identifies the channel information and the deleting instruction in the configuration information.
S220, the main control disk adaptation layer searches the keyword corresponding to the channel information in the keyword list.
S230, judging whether the keyword is found, if so, entering the step S240; if not, ending.
And S240, deleting the key words and the corresponding channel information according to the channel information, and ending.
A fourth embodiment of the present invention provides a method for managing service resources, where on the basis of the third embodiment of the present invention, a master control disk adaptation layer reports and issues a SysPort ID through a User Datagram Protocol (UDP) message.
Specifically, the designated fields of the UDP packets are written in by preset command keywords between the master control disk adaptation layer, the network manager, the control plane, and the individual disks, and a Node Management Unit (NMU) -individual disk Management Unit (BMU) protocol is used to report and issue SysPort ID, FapId, and FapPort through an existing NMU-BMU communication channel, where the reporting format of the service resources is shown in table four:
