Description
Technical Field
The invention relates to a method for realizing resource management in an IP telecommunication network system, in particular to a resource management method based on a signaling mechanism in the IP telecommunication network system, belonging to the technical field of communication.
Background
Currently, the Internet is the second largest network system to telecommunication networks. IP networks have gained widespread use because of the success of the Internet. An extremely large number of application services have been opened on the Internet and have entered the field of conventional telecommunication services, thereby causing a great impact on the monopoly of telecommunication. On the other hand, the conventional TDM (Time Division Multiplexing) technology cannot meet the requirement of the vigorous development of the multimedia service, and particularly, it has difficulty in scheduling resources and cannot meet the requirement of the multimedia service having the characteristics of broadband, narrowband, real-Time and non-real-Time at the same Time. Based on the existence of these real problems, the telecom experts are beginning to review the development direction of the telecom network.
Currently, most experts in the communication and information fields recognize the IP network as the development direction of the next generation network. However, the current IP network is based on the existing Internet technology and design concept. One of the biggest technical obstacles presented by the IP network is the "quality of service" (QoS) problem. Although the research work for solving the problem of the "quality of service" of the IP network has never been stopped since the american began to propose the concept of the next generation internet (ngi) in 1996, technical schemes such as "inter-serv", "diff-serv", traffic engineering, RSVP, MPLS, etc. have been proposed in sequence, and in recent years, resource management schemes based on signaling have been proposed again. However, all the technical solutions proposed so far are not ideal solutions, either too complicated or poor in scalability.
With the current telecommunications network technology in the context of fundamental transformation procedures, it is increasingly recognized that next generation telecommunications networks should employ IP networks based on packet-switched technology and non-connection oriented operation. For this reason, the present inventors proposed a technical idea of an IP telecommunication network and applied for an invention patent (patent application No. 200410037641.0, application date: 2004, 4/28/2005, and publication date: 2005, 2/9/2005). Compared with the existing Internet, the IP telecommunication network has the advantages that the telecommunication network provides trust and security mechanisms, has high stability, reliability and manageability of the telecommunication network, and can manage and control resources, so that the IP telecommunication network is a safe, trusted, controllable and manageable network.
In the technical scheme of the IP telecommunication network, a special double-address technology is adopted, and a complex address connectionless data network (hereinafter, referred to as NCT data network) and an address mapping device ADT for realizing double-address mapping are introduced, so that a new resource management technology is caused. Therefore, the technical means for implementing resource management in an IP telecommunications network is very different from the prior art. The invention provides a technical scheme for realizing resource management in the IP telecommunication network system.

and after the communication is finished, the connection is dismantled, and the released resources are added back to the resource table of the virtual private network.
In the process of establishing the connection, if the resources belonging to the virtual private network cannot meet the resources required by the connection in the nodes along the path, the connection cannot be established.
In the communication process, access control is only carried out at the edge gateway equipment, and the node equipment participating in the virtual private network does not carry out resource control and management.

Detailed Description
As shown in fig. 1, in the invention patent application "IP telecommunication network system and its implementation method", the inventor proposes a specific implementation scheme of IP telecommunication network. The IP telecommunication network includes a complex address connectionless data network (hereinafter abbreviated as NCT data network) as an "internal network" and an IP network as an "external network", and the NCT data network and the IP network are connected by an edge gateway device ED. The NCT data network of the inner layer and the IP network of the outer layer use the NCT address and the IP address respectively for addressing, and the address mapping device ADT stores the mapping relation between the two sets of addresses in the internal address mapping table. All devices and edge gateway devices in the NCT data network are allocated with NCT addresses, all devices and edge gateway devices in the IP network are allocated with IP addresses, and the edge gateway devices are connected with the address mapping devices after being authenticated. In an IP telecommunication network system, NCT data networks adopt a hierarchical architecture similar to the existing telecommunication switching network, and are composed of a core layer device CR, a convergence layer device MR, an access layer device AR, a network management device and an address mapping device, and communication among the NCT data networks is realized through the respective core layer device CR. The addressing is done inside the NCT data network using the NCT address.
The above-mentioned IP telecommunication network as the implementation scheme of the next generation telecommunication network must adopt a new resource management mechanism in order to fully utilize the hardware resources of the IP telecommunication network, flexibly and efficiently meet the requirements of telecommunication users in many aspects, and ensure that all telecommunication services running on the IP telecommunication network obtain the expected service quality guarantee. For this reason, the present inventors propose a resource management method based on a signaling mechanism, aiming at technical characteristics of an IP telecommunication network. The method is particularly suitable for telecommunication users and enterprise users who only have a small amount of resources. In this case, the resource requirement of the telecommunication users can be directly satisfied by a technical means of establishing a plurality of virtual private networks, that is, services in the IP network are divided into several types, each type of service includes a plurality of virtual private networks, and different telecommunication users are respectively satisfied. Each virtual private network has independent resources, and the resources in each virtual private network are managed through signaling, so that the resource requirements of users are guaranteed.
As shown in fig. 2, the resource management method based on the signaling mechanism can be divided into two main stages, which are: 1. establishing a VPN to realize resource allocation; 2. and performing access control and resource management through signaling. This is explained in more detail below.
One feature of the IP telecommunication network is that a virtual private network with independent resources is established for resource management. The process of resource allocation and the process of establishing the virtual private network are carried out synchronously. For a detailed description of the process, reference may be made to the inventor's prior patent application "method for implementing a virtual private network in an IP telecommunication network system" (application No.: 200410062652.4, application date: 7/8/2004). The following is only a brief description of the procedure for establishing a virtual private network.
In an IP telecommunication network, there are two methods for configuring resources (i.e. establishing a virtual private network) for network node devices, which are respectively described as follows:
the first method comprises the following steps:
) A user needing resources puts forward network resource requirements to network management equipment;
the network resource requirement is very specific network resource configuration information, including traffic among nodes, flow direction table, and service category content.
) The network management equipment calculates the resources required by each link of the network node equipment according to the resource requirements of the telecommunication users and determines the number of the virtual private network. The network management equipment sends a resource configuration command with information of service types, virtual private network numbers, resource requirements and the like to network node equipment in the NCT data network;
) And the network node equipment receives the resource configuration command and sends out a confirmation response or a rejection response according to the condition of each link resource of the network node equipment.
And if the resources owned by the network node equipment can meet the resources required by the resource configuration command, sending a confirmation response, and otherwise, sending a rejection response.
) After receiving the confirmation responses of all the related network node devices, the network management device sends a command with parameters such as service types, virtual private network numbers and the like to the address translation device ADT, and after the ADT device returns the confirmation responses, the virtual private network is established.
The second method comprises the following steps:
) Telecommunication users needing resources put forward network resource requirements to network management equipment;
the network resource requirement is very specific network resource configuration information, including contents such as traffic, flow table, service category, and the like between nodes.
) The network management equipment sends a resource configuration command with service type and resource requirement to the ED equipment;
) The source end ED equipment sends a virtual private network configuration request to the destination end ED according to the main route of the NCT data network, or starts a standby route of the NCT data network to send the virtual private network configuration request at the same time;
) Each NCT data network node equipment which passes through responds according to own resource conditions after receiving the request: if the resource condition of the node can be supported, the NCT data network node equipment configures link resources according to the request and forwards the request to the next node until the destination end ED equipment; the destination ED device sends an acceptance response to the source ED device if the resources of the destination ED device can support. If the source ED device receives the acceptance response of the destination ED device, the source ED immediately sends an acknowledgement response back to the network management device.
) And the network management equipment receives the confirmation responses of all ED equipment participating in the virtual private network and sends a command with parameters such as service types, virtual private network numbers and the like to the ADT equipment. The ADT receives the command from the network management device, i.e. sends back an acknowledgement response. The network management device receives the confirmation response. The virtual private network is successfully established.
And if the resource condition of the node equipment or the destination ED equipment is not supported, the NCT node equipment or the destination ED equipment sends a rejection response to the source ED equipment. The configuration is invalid. If the start timing of the source ED device is overtime, the source ED device does not receive the accept/reject response, and the source ED device also considers that the configuration is invalid. Both of the above cases consider the establishment of the vpn unsuccessful.
The method for establishing the virtual private network by forwarding each node after the source end ED equipment sends out the virtual private network configuration request can establish the virtual private network according to the current network condition and realize resource configuration.
It is clearly inappropriate to employ a link resource threshold alarm mechanism for VPN users with a small amount of resources, since even if the alarm threshold is set at 50%, for example: a certain link resource in the VPN is set to be 2M and occupies 900K at present, because the VPN obviously cannot alarm when the alarm threshold is not reached, if a call requiring 1.2M is to be accessed, it cannot be known at the network access end that a certain link resource in the network is insufficient, because there is no resource alarm information, the access end still accesses the call, and obviously, the VPN "crowds" resources of other people, which is not allowed, because it cannot ensure resource allocation of the network.
In this case, a signaling mechanism is required to accurately allocate the resources.
Specifically, for a VPN user with a small amount of resources, each time a service (call) is connected, a connection needs to be established between an ED (sending end) and an ED (receiving end), and in the connection establishment process, the resources required by the service are determined. If the link resource along the way can satisfy the requirement of the service, the connection can be established, and if the resource can not be satisfied, the connection can not be established.
The specific steps of the signaling mechanism are as follows:
) The ED (sending end) equipment directly sends out a connection establishment request command with parameters such as the ED address of the receiving end, the resource requirement and the like according to the resource requirement of a user.
) After receiving the command, each node device through which the connection establishment request command passes makes a corresponding reaction according to the condition of VPN stock resources, the VPN stock resources of the node can support the resources required by the connection establishment request command, the connection establishment request command is sent to the next node device, and if the VPN stock resources of the node cannot support the resources required by the connection establishment request command, a connection establishment failure response is sent to an ED (sending end) device.
) When the ED (receiving end) device receives the connection establishment request command, indicating that the resources of the VPN in the whole process can meet the resource requirement of the call, the ED (receiving end) device sends a connection establishment confirmation response to the ED (transmitting end) device.
) The node device through which the connection establishment confirmation response passes deducts the resource used by the connection from the VPN resource table, and the ED (sending end) device receives the connection establishment confirmation response, and the connection establishment is successful.
V) entering a normal communication phase.
Completion of the communication will proceed to a connection teardown procedure.
VI) both the ED (sending end) device and the ED (receiving end) device may initiate a connection teardown procedure, taking the example where the ED (sending end) device initiates the connection teardown procedure: the ED (sending end) device sends a connection removal request command with parameters such as the receiving end ED address and resources.
VII) after each node equipment passing the connection removal request command receives the command, releasing the resource occupied by the connection, correspondingly increasing the part of resource in the VPN resource table, and sending the connection removal request command to the next node equipment
VIII) when the ED (receiving end) device receives the connection removal request command, the ED (receiving end) device sends a connection removal confirmation response to the ED (sending end) device, the ED (sending end) device receives the connection removal confirmation response, and the connection removal is successful.
In the process of communication, access control is only carried out at the edge gateway equipment, and the node equipment participating in the virtual private network does not carry out resource control and management.
The above has described in detail a resource management method based on a signaling mechanism in an IP telecommunication network, but it is obvious that the specific implementation form of the present invention is not limited thereto. It will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit of the process of the invention and the scope of the claims.
