Description
Technical field
The present invention relates to the network communications technology, particularly based on the IP Telecommunication Network implementation method in tunnel.
Background technology
Nowadays the high speed development of the Internet, the business on it emerges in an endless stream, but existing Internet architecture transmission data are to adopt the mechanism of doing one's best, management, control ability deficiency.Can't ensure the quality of products to the business demand that bandwidth guarantees, real-time is had relatively high expectations at current speech, video, special line etc.But also produced following several network indeterminacy phenomenons be:
The one, the communication path uncertainty: a plurality of packets from the information source to the stay of two nights may pass through different network paths, and the different time periods also may have different network paths;
The 2nd, the not true property of communication flows: because existing IP network does not have the control ability of network insertion quantity, the control ability that does not also have the network insertion flow, possible certain time point very big flow occurs at certain node of network, the ability that surpasses node, new user inserts or new flow injects but at this moment still may have, this uncertain flow causes network local congestion, causes accessed user's communication to be affected;
The 3rd, the uncertainty of communication delay: because above-mentioned two kinds of uncertainties, data message is subjected to the influence of network path, network congestion situation by the delay of network, has uncertainty.
At above network presence, numerous enterprises and tissue propose various solutions, mainly comprise following three kinds of schemes:
First kind is by introducing QoS (service quality) mechanism on existing network.The research of this respect is a lot, comprise that particularly IntServ (integrated service) and DiffServ (Differentiated Services) dual mode are the most outstanding, but IntServ is subjected to its autgmentability to influence the success that does not obtain in the application, the success that DiffServ has autgmentability preferably and obtained using, but still do not solve the uncertain problem of above-mentioned network, so still do not solve the problem that IP network provides the carrier class business fully.
Second kind is to adopt the new network system to set up brand-new IP network.This mode is feasible technically, but because existing IP network exists in a large number, the jettisoning present networks to set up new network, the huge and serious waste of resources of its cost.Technically, some schemes adopt independent but can with the mode of existing IP network compatibility, this mode obtains still can not dealing with problems fully before QoS ensures in IP network itself.
The third is to introduce new network control layer on existing IP network, and the control of resource management and user admission is provided, and realizes that the controllability of network and IP QoS support.This be current I TU (International Telecommunications Union) just in standardized a kind of mode, but still there are some problems in this mode.Standard recommendation is only disposed borde gateway equipment in network, realize the related functional entities except that disposing but realize real resource control, data equipment itself a lot of new requirements have also been expanded, these new requirements cause deploy resources control may need to dispose the data equipment of new data equipment or transformation and upgrade replacement existing network, may need a large amount of inputs can make bearer network possess fairly perfect resource control ability.The upgrading of actual whole network equipment, the particularly upgrading of some core systems can become a kind of obstacle of enforcement.On the other hand, this technology is set up omnidistance LSP (label switched path) based on MPLS (multiprotocol label switching) technology on existing IP network, data traffic all devices on the network path of process all need to safeguard the relevant mark of bar LSP therewith, existing node has been proposed the requirement of mark capacity, because two communication end point users (as the voice communication between two users) are just corresponding LSP, and original equipment is to be that equivalence class is set up corresponding LSP with the sub-network, comprising under the such service application situation of voice communication, the former scale has enlarged much than the latter, this needs the extending marking capacity could satisfy communication for the IP/MPLS equipment of existing network operation.
Based on present networks, explore more practical approach, reduce the particularly replacing or the upgrading influence of nucleus equipment of existing network as far as possible, reduce the performance difficulty of IP Telecommunication Network, be the significant problem that needs to be resolved hurrily.
Summary of the invention
Technical problem to be solved by this invention, just provide a kind of IP Telecommunication Network implementation method based on the tunnel, with lower cost, under the situation that does not change the existing network framework, seamlessly transit, realize user's service quality assurance end to end, the business of the multiple IP QoS grade that suits the requirements is provided for the user.
The present invention solve the technical problem, and the technical scheme of employing is that the IP Telecommunication Network implementation method based on the tunnel comprises the steps:
A, network is divided into resource domains;
B, set up resource tunnels according to the bandwidth resources in the resource domains; Described resource tunnels can be seized the bandwidth in the network, guarantees that the needed bandwidth of resource tunnels is guaranteed;
C, between resource tunnels inside and resource domains, set up the user tunnel; The bandwidth resources in described user tunnel necessarily are guaranteed;
D, data traffic are transmitted in the inner user tunnel that passes through of resource domains;
Concrete, the user tunnel comprises permanent tunnel and calls out the tunnel that permanent tunnel is the user tunnel of always safeguarding; Calling out the tunnel is according to the interim user tunnel of setting up of service needed, and is released after finishing communication;
Concrete, when carrying out the data traffic forwarding, user's access node shines upon customer flow in the user tunnel, and in network message encapsulation user's tunnel label and resource tunnels mark, node in the middle of the resource tunnels is directly transmitted according to the tunnel label in the message, and the subscriber's outlet node is then removed user's tunnel label and resource tunnels mark;
Further, when carrying out the data traffic forwarding, the resource tunnels Egress node is removed the resource tunnels mark, and to user's tunneling family tunnel label swap operation, then flow is given the Ingress node of follow-up resource tunnels;
Further, user's tunnel label only need be installed at resource domains Egress node and resource domains Ingress node in described user tunnel, need not the installation processing and the exchange process of the middle node perceived user's tunnel label of resource domains;
Further, the described resource tunnels of setting up is to set up other many tunnels of corresponding different IP QoS level according to bandwidth resources and different IP QoS rank between two nodes;
Further, the user tunnel of resource domains inside has identical IP QoS rank with the resource tunnels at its place, and data traffic has same levels in the user tunnel of process in repeating process;
Further, other each the bar resource tunnels of corresponding different IP QoS level in the same resource domains can be passed through different network paths;
Further, resource tunnels the node of fullpath of process can specify.
The invention has the beneficial effects as follows that management, control ability are stronger.Introduce tunneling technique, be convenient to carry out resource management, and be that mode by the network planning designs the tunnel, can strengthen the controllability and the manageability of network like this.Can carry out smooth upgrade on existing IP network, the network after the upgrading can provide guaranteed IP QoS grade service for the user, satisfies professional needs such as quality data private line service and voice, video, realizes the support to carrier class IP service.Technology of the present invention has transitional preferably, can protect the investment of existing IP network preferably, with lower network construction cost upgrading present networks.On the other hand,, effectively reduced participating user communication and set up and the number of nodes of controlling, also helped improving the efficient of call control procedure and maintaining easily by the tunnel technology.

Embodiment
Below in conjunction with drawings and Examples, describe technical scheme of the present invention in detail.
The present invention plans physical network, form a plurality of independently resource domains, in resource domains, set up the resource tunnels of dividing the territory, the data traffic of different business quality requirement is included in the different resource tunnels, the realization user data traffic is transmitted in the resource tunnels that meets User IP QoS class requirement, guarantees the qos requirement of customer service.For the communication service of certain particular user, set up omnidistance user tunnel again in resource tunnels inside, the user passes in the tunnel resource tunnels and forms multi-layer tunnel, and the user tunnel has rigidity characteristic, and promptly the desired resource in user tunnel necessarily is met.The user tunnel carries out the resource access control with regard to strictness when setting up, guarantee that rigidity user tunnel obtains reliable resource and guarantees.
Embodiment
Fig. 1 is the schematic diagram of a physical network, and Fig. 2 is based on this physical network and uses a configuration diagram of the present invention.Below the IP Telecommunication Network implementation method that the present invention is based on the tunnel is described:
One, resource tunnels is set up in the divide resource territory.In this example, at first according to the zone and the management characteristic of physical network, physical network is divided into a plurality of resource domains (RD) of stratification.The division of resource domains forms when the network planning among the present invention, and each resource domains has the management of corresponding explorer (RDM) realization to Internet resources.
In resource domains, bandwidth resources are carried out tunnel, form resource tunnels (RT).The bandwidth resources tunnel is according to the demand characteristic of business to resource, and (other division of IP QoS level is referring to the relevant criterion ITU-TY.1451 of ITU) sets up other many tunnels of corresponding different QoS level between two nodes according to different IP QoS rank.For the resource tunnels that forms, the starting point in tunnel and terminal point are that the network planning forms, even the network path in tunnel also can be formed by the network planning.Simultaneously can make full use of the tunnel signaling mechanism of existing network, and utilize the network protection technology to obtain the high reliability in tunnel.Between two fringe nodes of each resource domains, between the N1 among Fig. 2 and N2, N3 and N4, have many tunnels, as the RT1 among Fig. 2, RT0, they are corresponding to the resource characteristic of different IP QoS grade.These internodal in twos resource tunnels can be passed through different network paths in resource domains.Network Transmission for a complete business datum flow, Web portal node from customer service, or be called user's access node (the N1 node among Fig. 2) beginning, arrive the network edge node that is connecting the purpose user through a plurality of resource tunnels, as the N4 among Fig. 2 (being also referred to as the subscriber's outlet node), this moment the path in related resource territory of process form a multistage tunnel successively by the resource tunnels in the related resource territory.For not by the resource of tunnel, the resource consistence of its resource characteristics and existing internet, its QoS to user data guarantees to be exactly existing " doing one's best " mechanism, and does not have the data isolation characteristic.
The technology of setting up of resource tunnels can be utilized the ripe tunneling technique on the existing IP/MPLS network, as MPLS traffic engineering tunnel technology.MPLS traffic engineering tunnel technology is a kind of route technology that can support explicit route, and it can be by artificial planning, and allowing the tunnel pass through the node that some specific node even entire path pass through can specify, thereby has definite network path.Simultaneously, it also can utilize existing traffic engineering fast reroute techniques, and the high reliability that obtains resource tunnels guarantees, can realize the protection level of 50ms.In concrete enforcement, can be according to the grade of IP QoS, between the fringe node of two resource domains (between the N1 among Fig. 2 and N2, N3 and N4), set up other many resource tunnels of different IP QoS level, and other resource tunnels of these different IP QoS level can make it pass through different nodes by planning.
Resource tunnels the intermediate node of process, need the preferential resource tunnels forwarding of flow that guarantees, and for other a plurality of resource tunnels of different IP QoS level, on the priority of transmitting, distinguished, to guarantee that resource tunnels different IP QoS priority is guaranteed among the present invention, this is supported in existing IP network router.If adopt above-mentioned MPLS traffic engineering tunnel technology, can in tunnel label, be discerned and be distinguished, and be implemented different forwarding priority strategies by different EXP (excellent level marker bit).
Fig. 2 is on physical network basis shown in Figure 1, by the network planning, physical network planning is formed resource domains 1 and 2 two resource domains of resource domains, and disposes the explorer (RDM1 among Fig. 2 and RDM2) in the territory.In resource domains 1, the fringe node that two nodes of N1 and N2 are these resource domains, planning forms resource tunnels RT0 and RT1 between N1 and N2, the IP QoS rank that RT0 is corresponding different respectively with RT1, RT0 and RT1 can pass through identical or different network path, suppose that here they pass through different network paths.Here two kinds of IP QoS ranks are only planned in supposition, corresponding real time business (C0) and non-real-time data business (C1), and RT0 is used for carrying other business of C0 level, and RT1 is used for carrying other business of C1 level.For resource domains 2, same planning has formed resource tunnels RT0 and the RT1 between fringe node N3 and the N4.
Resource tunnels described in the present invention is a unidirectional tunnel, in order to satisfy two-way communicating requirement, sets up the resource tunnels of different directions between two nodes, and the technology that is adopted is just the same, and independently carries out maintenance and management.Resource tunnels shown in Figure 2 has only been illustrated the unidirectional resource tunnels from N1 to N2, from N3 to N4.These resource tunnels are collected and managed to explorer among Fig. 2 (RDM1 and RDM2).
Two, the user tunnel is set up and control.In resource tunnels, set up the user tunnel that has corresponding IP QoS grade end to end.The user tunnel is from access node (N1 Fig. 2) beginning of network, pass through above-mentioned segmentation resource tunnels, arrive the network edge node (N4 among Fig. 2) that target connected, the node (not shown among Fig. 2) in the middle of the resource tunnels also is indifferent to the user tunnel of tunnel internal.According to the IP QoS class requirement in user tunnel, network is realized the control in user tunnel by the resource tunnels of corresponding grade characteristic.The user tunnel has comprised permanent tunnel and has called out the tunnel that permanent tunnel is to continue the user tunnel that maintenance is set up, and is applied to individual line subscriber; Calling out the tunnel is according to the interim user tunnel of setting up of service needed, and is released after finishing communication, is applied to video, voice etc. and has the business of calling out character.No matter be permanent tunnel or calling tunnel, before foundation, all to be subjected to network and admit the restriction of mechanism, resource operating position according to network, check that the tunnel that whether can support new user inserts, guarantee that the network accessed user can obtain necessary resource, avoids influencing accessed user's service quality.In addition, be that permanent tunnel or calling tunnel all are the rigidity tunnels, promptly the bandwidth of network must guarantee.
Reach omnidistance IP QoS effect, require the user tunnel to arise from user's access node (as the N1 among Fig. 2) of certain resource tunnels of network, the receiving node of place, opposite end resource tunnels (as the N4 among Fig. 2) finally.The user tunnel has the important attribute of bandwidth and two aspects of IPQoS class requirement.The user passes in the tunnel one or more resource tunnels with identical IP QoS grade, and the resource tunnels of being passed through forms user's tunnel path (UTP), and it is the continuous resource tunnels of multistage.The formation of user's tunnel path is formed by explorer calculating.The user tunnel is owing to pass through outer field resource tunnels, and resource tunnels can have resist technology to support its feasibility, so the user tunnel obtains reliability thus.Data traffic is transmitted in the user tunnel, and bearing bed can guarantee that by promising to undertake speed (CAR) mechanism meets the bandwidth constraints in user tunnel at Web portal (as the N1 node among Fig. 2) Limit Bandwidth Usage.
The user tunnel has comprised permanent tunnel and has called out the tunnel.Permanent tunnel continues to set up and keep, and it is not controlled by the admittance of network.Just set up when needs are communicated by letter and call out the tunnel temporarily, may exist the user tunnel to set up unsuccessful situation, comprise that the user inserts owing to certain strategy is rejected, or be rejected (call loss of similar PSTN) owing to Internet resources are not enough.When the user when network proposes communication request, carry out the tunnel resource request by user access point (N1 among Fig. 2) to the explorer (RDM1) of place resource domains and calculate, and implement to call out access control (CAC) at this moment according to strategy.Explorer will calculate user's tunnel path (UTP) according to association requests parameter (bandwidth, qos parameter), and carry out the interaction between the network entity, bandwidth resource on UTP.For the calculating of user's tunnel path, can be to calculate omnidistance UTP (adopt strict show route technology) by the access-in resource territory, also can adopt the segmentation calculation mode to calculate UTP (will with loose demonstration route technology).Relevant computational algorithm generally is SPF (SPF) or CSPF (Constraint Shortest Path First) algorithm.
Among the present invention, the user tunnel adopts label switching to come the path in maintenance customer tunnel, forms the user of user tunnel from Web portal to outlet thus and connects switching path.As Fig. 2, user U1 need have communicating by letter that real-time requires with user U2, and U1 communicates to setting up user tunnel (UT) between the U2, and UT passes resource tunnels RT0 in the resource domains 1 and the resource tunnels RT0 of resource domains 2 arrives N4 from N1.The process of setting up and prior art for the user tunnel have following difference:
Ask at the user, when the explorer of each resource domains all calculates can carry out the setting up of user tunnel the time, will be by the Egress node N4 distributing user tunnel label of the resource tunnels that is connected with the purpose user, this mark will be announced head node N3 to respective resources tunnel in this resource domains by explorer RDM2.Because this head node is not the start node of striding resource domains user tunnel, then the node N3 user's mark of will reallocating is given the explorer RDM2 of this resource domains, and at this node user's tunnel label is installed; By the explorer RDM2 of this resource domains this user's mark is notified to the explorer RDM1 of upstream simultaneously.User's mark has comprised going into mark, has gone out mark, next jumps out interface, and it mouthful is corresponding resource tunnels interface that here next jumped out.In above-mentioned user's tunnel label distribution procedure, the not distribution of participating user tunnel label of node in the middle of the resource tunnels, also not perception user tunnel label.
Fig. 3 is that the mark in the user tunnel (N1 is to N4) under Fig. 2 network condition distributes and installation process.This process is all to calculate at RDM1 and RDM2 to set up the process of N1 behind the user tunnel (from U1 to U2) of N4, may further comprise the steps:
(1) N4 distribute labels L1 gives RDM2; And finish in the label L 1 of this locality and install, L1 is ejection in the command code of this locality;
(2) RDM2 transmits label L 1 and gives N3, and its Export resource tunnel is RT0;
(3) N3 distribute labels L2 gives RDM2, and next of L2 jumped and be N3; And at local adjustment notch L2, the command code of L2 goes out to be labeled as L1 for exchange, and its outgoing interface is the interface of resource tunnels RT0 correspondence;
(4) RDM2 transmits label L 2 and gives RDM1, and next of L2 jumped and be N3;
(5) RDM1 transmits label L 2 and gives N2, and it exports next jumping and is N3;
(6) N2 distribute labels L3 gives RDM1, and next of L3 jumped and be N2; And local label L 3 is installed, and its marking operation sign indicating number goes out to be labeled as L2 for exchange, and next is jumped and is N3;
(7) RDM1 transmits label L 3 and gives N1, and its Export resource tunnel is RT0;
(8) N1 adjustment notch L3, the command code of L3 is for being pressed into, and outgoing interface is the interface of resource tunnels RT0 correspondence.
Through said process, set up a user tunnel from access node N1 to Egress node N4, its mark is as follows: L3 → (L3, L2) → (L2, L1).User's tunnel label only the resource tunnels two ends of process install, the node in the middle of the resource tunnels does not relate to the installation processing procedure in user tunnel, thus also not perception user tunnel label.
Three, user data traffic is transmitted.When data traffic enters network, corresponding network access equipment will be mapped to customer flow in the user tunnel according to the feature of customer flow and transmit among the present invention.This comprises two steps:
(1) user's mark encapsulation: customer flow is carried out the mark encapsulation in user tunnel;
(2) resource tunnels encapsulation: the resource tunnels associated according to user's mark, (1) formed encapsulation is carried out once more the mark encapsulation of outer resource tunnels.
In follow-up exchange process, the resource tunnels intermediate node only carries out label switched operation according to outer mark, gives next-hop node on the resource tunnels path with traffic transport.The resource tunnels intermediate node does not carry out any operation to user's tunnel label.
The Egress node of resource tunnels (as the N2 among Fig. 2, N4) will be removed the resource tunnels mark, operate according to the marking operation sign indicating number in inner users tunnel.If not the final stage resource tunnels, node N2 will carry out swap operation to user's tunnel label, send the Ingress node N3 of adjacent next section resource tunnels to; If being subscriber's outlet node N4, final stage resource tunnels, the end-node of resource tunnels will customer flow be transmitted on outgoing interface according to user's mark.
Non-first section resource tunnels head node (as the N3 among Fig. 2) after receiving customer flow, will at first carry out the label switched in user tunnel, and according to going out the associated resource tunnels of mark, flow sent into corresponding resource tunnels transmit.
As Fig. 3, the real time data flow from U1 to U2, its transmitting step is as follows:
(1) at the N1 node with at first packed user's tunnel label L3, the associated resource tunnels of L3 is RT0, the N1 node is the mark of encapsulation resource tunnel RT0 once more, flow is transferred to the N2 node then;
(2) N2 node (first section resource tunnels Egress node) is after removing the resource tunnels mark, and (L3 L2), gives the N3 node with traffic transport then to carry out label switched according to user's tunnel label;
(3) the N3 node according to user's tunnel label L2 carry out user's tunnel label exchange (L2, L1), the N3 node is the mark of encapsulation resource tunnel RT0 once more, flow is transferred to the N4 node then;
(4) the N4 node according to user's tunnel label, is transmitted to user U2 with flow after removing outer resource tunnels mark.
In the said process, as shown in Figure 1 in the physical network, only N1, N2, N3, N4 perception user's tunnel label and exchange handle.
The present invention is based on the IP Telecommunication Network implementation method in tunnel,, dispose corresponding tunnel endpoint device and resource domains management equipment thereon, realize support IP Telecommunication Network mechanism of the present invention based on present networks.Node in the middle of the resource tunnels does not relate to the maintenance and the perception in user tunnel, do not need to guarantee upgrading or replacing to the resource tunnels intermediate node, helps the upgrade application of IP Telecommunication Network on existing IP network.It can be gradual progressively upgrading deployment way, as only between Chengdu and Beijing, disposing, network after the upgrading can provide guaranteed IP QoS grade service for the user, satisfy professional needs such as quality data private line service and voice, video, realize support carrier class IP service.Simultaneously, have technical compatibility preferably based on the IP Telecommunication Network technology of tunnel, some technology of existing network can be applied, thereby as can continue to use the high availability that network is provided based on the MPLS fast reroute techniques.But the characteristics of this smooth upgrade can be protected the investment of existing IP network preferably, with lower network construction cost upgrading present networks.
