困21示出由现有的IP/MPLS节点构成的网络.在IP/MPLS内的网络中,节点接口的交換能力全部是PSC (能分组交换).MPLS结构是为了支持以标签为基础的数据传送而定义的(例如,参照非专利文献l).在RFC3031中,LSR (标签交换路由器)是指具有能识别IP分组或小区(带标签的IP分组)边界的数椐传送面并与IP分组标趙或小区标題的内容对应进行数据传送处理的节点.在GMPLS中,LSR不仅仅是与IP分组标甩或小区标題的内容对应进行数据传送处理的节点.GMPLS中的LSR还包含以时咪、波长、光纤的物理端口的信息为基础进行传送处理的设备. 21 shows a network configuration trapped by a conventional IP / MPLS node in the network IP / MPLS, the exchange capacity of all the PSC node interface (capable of packet switching) .mpls structure to support a label based data defined transmission (e.g., refer to Non-Patent Document l). in the RFC3031, the LSR (label Switch router) refers to the number noted transfer surface has to identify cells or IP packets (IP packets with labels) and the IP packet boundaries Zhao or standard cell header corresponding to the content data transfer processing node in the GMPLS, just LSR node .GMPLS data transfer processing in the IP packet LSR rejection standard cell header corresponding to the content or further contains when the microphone, the wavelength information of the physical port of an optical fiber transmission processing apparatus is based.

另一方面,GMPLS中的LSR的接口将每一个交换能力分成PSC (能分组交换)、TDM(能时分多路)、LSC(能入交換)、FSC(能光纤交换) 4类.此外,困22A~困22D示出GMPLS中的标签的概念. On the other hand, in the GMPLS LSR interface into each of the PSC-exchange capacity (capable of packet switching), the TDM (time division multiplexing can), the LSC (the energy exchange), the FSC (optical energy exchange) class 4. Further, sleepy 22A ~ 22D conceptually illustrates trapped in a GMPLS label.

(PSC的说明) (PSC explanation)

PCS的接口可以识别IP分组或小区的边界,与IP分组标趙或小区标題的内容对应进行数据传送处理.在困22A中,在分组层定义对每一个链路唯一定义的标签,对IP分组赋予标签,形成LSP(标签交换路径),困22A的链路是为了传送IP分组而在LSR间定义的链路. 当在SDH/SONET上传送IP分组时,是SDH/S0冊T路径,当在以太网(登录商标)上传送时,是以太网路径. (TDM的说明) PCS interface boundary may be identified IP packet or cell, and IP packet content or Zhao standard cell header corresponding to the data transfer process. Trapped in 22A, the packet link layer defines a uniquely defined for each label on the IP packet labels are assigned, form the LSP (label switched path), trapped link 22A and the link is defined for transmission between the LSR IP packets. when the IP packet is transmitted on the SDH / SONET, a SDH / S0 register T path, when transmitted over Ethernet (registered trademark), Ethernet path. (TDM explanation)

TDM的接口根据在时间上周期重复的时咪进行数据传送处理。 TDM interface for data transfer processing according to the period of repetition in time imidazole. 在闺22B中,在TDM层,标莶变成时味.作为TDM接口的例子,是DXC (数据交叉连接)的接口,将分配给输入側的时隙和分配给榆出側的时隙连接起来,形成TDM路径、即SDH/SONET珞径.链路有波长路径的情况,也有单单是光纤的情况. (LSC的说明) In Gui 22B, the TDM layer, when the scale becomes Siegesbeckiae taste. Examples of the TDM interface is the DXC (cross-connect data) interface, and a time slot assigned to the input side of the dispensing slot to an elm side is connected together to form TDM path, i.e. SDH / SONET Luo diameter. wavelength path link case, there is just the case of the optical fiber. (description of the LSC)

LSC的接口根据传送数振的光纤中的波长进行数振传送处理。 LSC interface for digital processing in accordance with the wavelength of the vibration transmitting fiber transmission number of vibration. 在困22C中,在X层,标签变成波长.作为LSC接口的例子,是OXC (光交又连接)的接口,将分配给输入側的波长和分配给输出側的波长连 In trapped 22C, the X layer, the wavelength of the tag becomes. Examples of LSC interface, is OXC (optical cross-connect in turn) interface, and a wavelength distribution assigned to the input side to the output side of the wavelength even

接起来,形成X路径.具有LSC的OXC的接口以波长羊位进行交换. (PSC的说明) Connected together to form X path. OXC interface having a wavelength of LSC sheep bits exchanged. (PSC description)

FSC的接口与传送数据的光纤的实际物理端口的位置对应进行数据传送处理.在闺22D,在光纤层,标签变成光纤.作为PSC接口的例子,是0XC的接口,将输入側的光纤和输出倒的光纤连接起来,形成光纤路径.具有FSC的0XC的接口以光纤单位进行交换.链路意味着光纤的物理集合,有电统管道(3 - ,卜)等. FSC position corresponding interface with the actual physical data transmission port data transfer processing of an optical fiber. In the Inner 22D, the fiber layer, the fiber becomes the label. Examples of the PSC interface is 0XC interface, and an input side optical fiber inverted output optical fiber connected to form an optical fiber path having the interface to the FSC 0XC fiber units means that the physical exchange link of the set of optical fibers, electrical conduit system. (3 -, Bu) and the like.

上述交换能力的接口可以分层使用.从上位层开始依次是FSC、 LSC、 TDM和PSC.在GMPLS中,将对上述各交换能力的路径称作LSP, 困23示出LSP的分层结构.PSC-LSP属于TDM-LSP, PSC-LSP的链路变成TDM-LSP. TDM-LSP厲于LSC-LSP, TDM-LSP的链路变成LSC-LSP, LSC-LSP变成FSC-LSP, LSC-LSP的链路变成FSC-LSP,此外,当考虑省略TDM层的愔况时,PSC-LSP属于LSC-LSP, PSC-LSP的链路变成LSC-LSP. LSC-LSP和PSC-LSP的关系和困22B的情况一样,越往下位层,LSP的带宽越宽. Interface said switching capabilities may use a hierarchical Starting from the upper layer followed by FSC, LSC, TDM and the PSC. In the GMPLS, each exchange capacity will be referred to as a path LSP, the LSP trapped 23 shows a hierarchical structure. PSC-LSP belongs TDM-LSP, PSC-LSP link becomes TDM-LSP. TDM-LSP in li LSC-LSP, TDM-LSP link becomes LSC-LSP, LSC-LSP becomes FSC-LSP, LSC-LSP link becomes FSC-LSP, in addition, be omitted when considering the TDM case yin layer, PSC-LSP belongs LSC-LSP, PSC-LSP link becomes LSC-LSP. LSC-LSP and PSC- 22B the relationship between the LSP and trapped as in the case, the down-level layer, the wider the bandwidth of the LSP.

在这样的现有技术中,例如,如困24所示,当具有PSC的交换能力和LSC的交换能力的GMPLS节点2、 3、 4、 5、 6和只具有PSC的功能IP/MPLS节点1、 7混存时,IP/MPLS节点与GMPLS协议不匹配. 因此,对于只具有PSC的功能IP/MPLS节点,为了使其与GMPLS协议匹配,如图25所示,在现有技术中,必须将所有的节点替换成按GMPLS 协议工作的GMPLS节点.因此,对于GMPLS节点的导入,使导入费用增加. In such prior art, e.g., as the storm 24, when the GMPLS node exchange capacity and exchange capacity of LSC having a PSC 2, 3, 4, 5, 6, and only a function of the PSC IP / MPLS node 1 , 7 coexist, IP / MPLS and GMPLS protocol does not match the node. Thus, the function for the IP / MPLS node having only the PSC, in order to match the GMPLS protocol, shown in Figure 25, in the prior art, must be replace all nodes operating according to the GMPLS node GMPLS protocol. Thus, the GMPLS node for introducing the import cost increase.

在GMPLS中,有将IP/MPLS扩展后的GMPLS用的路由协议和信令协议.对于GMPLS用的硌由协议,在GMPLS中,将所有层的LSP看成是上位层的链路,广告链路状态,因此,GMPLS网络内的节点保持所有链路的状态,并具有各层的拓朴结构.该拓朴结构的数据库为通信工程而作,称作GMPLS 'TED(通信工程数振库).各节点保持GMPLS 'TED, In GMPLS, the routing protocols and the GMPLS signaling protocol IP / MPLS with extended for use by Ge GMPLS protocol in the GMPLS, the LSP all layers upper layer as a link, chain advertising road state, nodes within the network GMPLS holding state of all links, and each layer having a topology. this topology database is made and communication engineering, known as GMPLS 'TED (the number of vibration communication Engineering library) each node maintains a GMPLS 'TED,

[实施例2〗 [Example 2〗

当实现链路的接口时,有通过分配IP地址来表现的号码方式和通过将作为节点识別符的IP地址和已在节点内分配固有的链路识別符组合来表现的非号码方式.将使用号码方式表现的链路称作号码链路,将使用非号码方式表现的链路称作非号码链路(例如,参照非专利文献7X When implemented interface link, there are number of ways to represent an IP address assigned by the number and manner by a non-node identifier assigned IP address and unique identifier of the link within the node to the performance of the composition. the embodiment represented using numbers called link link number, the number of non-used way to show a link called a non-link number (e.g., refer to non-Patent Document 7X

说明非号码链路.MPLS网络中的链路接口通常分配IP地址》通过IP地址可以识别网络内的链路.但是,在GMPLS中,l根光纤可以容纳100个以上的波长,若对各波长的接口分配IP地址,则需要的! Description "Link Link interface typically assigned an IP address non-link number .MPLS network IP address can be identified within the network. However, in the GMPLS, l fibers can hold more than 100 wavelengths, each wavelength for when interface to assign IP addresses, you need! P 地址将是一个庞大的数.此外,因各层的LSP作为TE链路对上位层广告,故若对各TE链路分配IP地址,则有IP地址资源枯竭之度. P address will be a large number. Further, because LSP of each layer as an upper layer TE link advertising, so if the TE link allocation to each IP address, the IP address of the depletion of resources.

因此,在GMPLS中,为了识别链路(以下,有时也将TE链路称作链路),导入对链路接口分配的链路识别符.IP地址虽然有必要对全球分配,但链路识別符只要在各路由器内是唯一的即可,通过(节点识别符、链路识別符)的組合,可以识别网络中的链路。 Thus, in the GMPLS, in order to identify the link (hereinafter sometimes referred to as the TE links link), although it is necessary to import the global identifier assigned to the link .IP link interface address assignment, but the link identification as long as the other symbol is unique to each router, by (node ​​identifier, link ID), a combination of network link may be identified.

由(节点识别符、链路识別符)的组合表现的链路称作非号码链 A (node ​​identifier, link ID) a combination of non-performance numbers called chain link

路.非号码是指不对链路的接口分配IP地址.因此,在GMPLS中, 要解决即使波长数增加或TE链路数增加IP地址资源也不枯竭的问趙. Road number refers to the non-IP address assigned to the interface does not link. Therefore, GMPLS, the number of wavelengths to be solved even if the increase in the number of links increase or TE IP address resources are not depleted asked Zhao.

基于这样的理由,在GMPLS群内通常使用非号码方式.但是,在IP/MPLS节点只处理号码链路而不处理非号码链路的情况下,当在GMPLS + IP/MPLS节点(边缘)之间设定了PSC-LSP时,有必要使其为非号码链路. For these reasons, in the group often using GMPLS number mode. However, in the case of IP / MPLS node only process without processing the number of non-link number of the link, when the GMPLS + IP / MPLS node (edge) of when set between the PSC-LSP, it is necessary to link non-number.

在困7A和困7B中,示出了号码链路和非号码链路的例子.如困7A所示,对于GMPLS群内的GMPLS + IP/MPLS节点或GMPLS节点,各层的链路除了PSC-LSP,都是非号码链路.PSC-LSP设定为号码链路-如困7B所示,对于GMPLS群外的IP/MPLS节点,在PSC-LSP的情况下,使用已对GMPLS群内使用的号码链路, 7A and 7B trapped in trapped in the example shown and the number of non-link number of the link. As shown trapped 7A, GMPLS + IP / MPLS or GMPLS node node, link layers except for the PSC group GMPLS -LSP, are non-link number .PSC-LSP link set number - eg stranded FIG. 7B, the outer group GMPLS IP / MPLS nodes using GMPLS group used for the PSC-LSP in the case of the number of links,

在困8A和困8B中,示出了号码链路和非号码链路的例子。 8A and 8B trapped in trapped in the example shown and the number of non-link number of the link. 如图8A所示,对于GMPLS群内的GMPLS + IP/MPLS节点或GMPLS节点,GMPLS 群内的所有层的链路都是非号码链路.如困8B所示,对于GMPLS群外的IP/MPLS节点,在PSC-LSP的情况下,将已对GMPLS群内使用的号码链路变换成非号码链路后再使用, 8A, the inner group GMPLS GMPLS + IP / MPLS or GMPLS node node, the link layer in all the groups are non-GMPLS link number as shown trapped 8B, the outer group GMPLS IP / MPLS node, when the PSC-LSP, and the number of links have been used in the GMPLS group into a non-link number before use,

这样,即使IP/MPLS节点只能处理号码链路,通过将PSC-LSP作为号码链路设定,IP/MPLS节点也可以不按照GMPLS协议动作。 Thus, even if the IP / MPLS node can handle link number, by the PSC-LSP is set as a link number, IP / MPLS node may not follow the GMPLS protocol operation.

[实施例3】 [Example 3]

当将PSC-LSP作为号码链路处理时,GMPLS + IP/MPLS节点(边蝝) 有必要将IP地址分配给该链路的接口, IP地址在网络内必须是固定的值.分配给各节点的PSCHLSP的接口的IP地址不能重复. When the PSC-LSP link treated as a number, GMPLS + IP / MPLS node (edge ​​young locust without wings) it is necessary to assign an IP address to the interface of the link, IP addresses must be a fixed value within the network. Assigned to each node PSCHLSP IP address of the interface can not be repeated.

如困9所示,假定PSC-LSP是动态设定的情况,各GMPLS + IP/MPLS As trapped 9, the PSC-LSP is assumed that the dynamic set, each GMPLS + IP / MPLS

节点(边缘)将能分配给本节点的IP地址预先存储在IP地址池16 中.存储在IP地址池16中的IP地址在网络内是固定的值.若在设定PSC-LSP时,各节点从IP地址池16中选择1个向链路分配的IP地址,并作为该链路的接口的IP地址取得.在两端的GMPLS + IP/MPLS 节点(边緣)进行该动作.通过发消息,将本节点取得的IP地址通知给对方的GMPLS + IP/MPLS节点(边缘). Node (edge) will be assigned to the local node IP address stored in advance in the IP address pool 16. IP address stored in the IP address pool 16 is a fixed value within the network. If the setting PSC-LSP, the respective from node 16 the IP address pool of IP addresses to link an assigned IP address of the interface as the link is made. in the ends of the GMPLS + IP / MPLS node (edge) of the operation performed by a message , the IP address of the node of the acquired notification to each other GMPLS + IP / MPLS node (edge).

困10示出具有IP地址池16的GMPLS + IP/MPLS节点(边缘)的构成.闺10的构成与困7A和困7B的设定例对应.即,在困7A和图7B的设定例中,如困7A所示,即使在GMPLS群内,也对PSC-LSP利用号码方式进行识別.困11示出具有IP地址池16和号码/非号码变换部15的GMPLS + IP/MPLS节点(边緣)的构成.困11的构成与困和困8B的设定例对应.即,在困8A和困8B的设定例中,使用号码/ 非号码变换部15,如困8A所示,在GMPLS群内,可以完全是非号码方式. 10 illustrates a GMPLS + trapped configured IP / MPLS node (edge) constituting the set 10 of the Inner trapped Example 7A and 7B trapped 16 having a corresponding IP address pool. That is, difficulties in setting example 7A and 7B , as shown trapped, even if the GMPLS group, also using a PSC-LSP mode number identified 7A. 11 shows trapped GMPLS + IP / MPLS node 16 and having the IP address pool number / number converting portion 15 of the non- (edge) configuration. configuration setting example 8B trapped trapped trapped and 11 corresponds That is, the trapped 8A and 8B trapped setting example, the use of numbers / number converting portion 15 non as shown trapped 8A in the GMPLS group, it can be completely non-number mode.

这样,即使PSCHLSP动态设定,通过预先将IP地址存储在IP地址池16中,链路的IP地址也可以动态地分配, Thus, even if the dynamic PSCHLSP set in advance by the IP address pool 16, the IP address of the link can be dynamically allocated IP address is stored,

[实施例4〗 [Example 4〗

在以上说明的实施例1~实施例3中,对于GMPLS网络,将能处理IP/MPLS协议的GMPLS + IP/MPLS节点限定在能与IP网络直接连接的边缘节点.在实施例4中,即使是不与IP网络直接连接的核心节点,也能如困12所示那样,将能处理GMPLS协议和IP/MPLS协议的GMPLS + IP/MPLS节点配置在GMPLS网络内. GMPLS + IP / MPLS node Example 3 In the above described embodiments 1 to embodiment, for GMPLS network, will be able to handle IP / MPLS protocol is defined in the edge nodes directly connected to the IP network. In Example 4, even core node is not directly connected to the IP network, it can be trapped as shown in FIG. 12, and will be able to handle GMPLS protocol IP / MPLS protocol GMPLS + IP / MPLS in the GMPLS network node configuration.

参照闺13A〜困13C说明实施例4的LSP设定的设定状况.在GMPLS + IP/MPLS节点(边缘)32和GMPLS+IP/MPLS节点(核心)36之间设定PSC-LSP.此外,在GMPLS + IP/MPLS节点(核心)36和GMPLS + IP/MPLS节点(边缘)39之间设定PSC-LSP.因PSC-LSP经LSC-LSP 设定,故在PSC-LSP设定之前,设定LSC-LSP*因此,GMPLS + IP/MPLS 节点(边缘)作为IP/MPLS的通常链路,对GMPLS网络外的IP/MPLS 节点使用. Referring Gui 13A~ trapped Example 13C and the LSP set by the setting condition 4 embodiment. PSC-LSP is set in the GMPLS + IP / MPLS node (edge) 32 and the GMPLS + IP / MPLS nodes 36 (core). Further , GMPLS + IP / MPLS node (core) 36 + IP / MPLS node set between the PSC-LSP 39 and the GMPLS (edge). by PSC-LSP by LSC-LSP setting, before it is set in the PSC-LSP setting LSC-LSP * Thus, GMPLS + IP / MPLS node (edge) as the IP / MPLS links generally, outside the IP network GMPLS / MPLS nodes.

当对IP/MPLS节点31和IP/MPLS节点41设定MPLS-LSP时, MPLS-LSP对IP/MPLS节点,将PSC-LSP作为通常的链路使用,因此, IP分组通过JIPLS-LSP内. When IP / MPLS node 31 and IP / MPLS node 41 set MPLS-LSP, MPLS-LSP as the PSC-LSP commonly used to link IP / MPLS node, therefore, the IP packet through the JIPLS-LSP.

此外,IP/MPLS节点31也有不经过MPLS-LSP对IP/MPLS节点" 传送IP分组的情况.这时,将在GMPLS + IP/MPLS节点(边缘)32和GMPLS + IP/MPLS节点(核心)36之间和在GMPLS + IP/MPLS节点(核心)36和GMPLS + IP/MPLS节点(边緣)39之间设定的PSC-LSP作为通常的链路,对IP/MPLS节点使用. In addition, IP / MPLS node 31 has not elapsed MPLS-LSP transmit IP packets to the IP / MPLS node. "At this time, the GMPLS + IP / MPLS node (edge) 32 and the GMPLS + IP / MPLS node (core) and, generally used as a link for IP / MPLS node GMPLS + IP / MPLS node (core) 36 and GMPLS + IP / MPLS node (edge) PSC-LSP 39 between the set 36.

困14示出由IP/MPLS节点、GMPLS + IP/MPLS节点和GMPLS节点构成的网络中的链路状态信息的管理状况.在闺14中示出IP/MPLS 节点保持的拓朴信息.实施例4和实施例1的不同点在于,即使GMPLS + IP/MPLS节点(核心)36不和IP/MPLS网络直接连接,也可以作为IP/MPLS路由器对IP/MPLS网络动作, 14 shows a management status trapped link state information network including IP / MPLS nodes, GMPLS + IP / MPLS and GMPLS node node. Gui 14 shown in topology information IP / MPLS node remains in Example and 4 differs from Example 1 in that, even if the GMPLS + IP / MPLS node (core) 36 and not IP / MPLS network is directly connected, as may be IP / MPLS router IP / MPLS network operation,

GMPLS群内的GMPLS节点管理GMPLS的链路状态.例如,当使用GMPLS用的路由协议在GMPLS内广告链路状态时,使用OpaqueLSA (例如参照非专利文献2、 4、 8 ).象对IP/MPLS路由器将在GMPLS + IP/MPLS 节点间设定的PSC-LSP作为通常的链路进行处理那样,以和IP/MPLS 节点间的链路相同的形态广告,例如,当使用OSPP路由协议时,使用路由器LSA(例如,参照非专利文献2), GMPLS GMPLS node link state managed in the GMPLS group. For example, when a GMPLS routing protocol used in the link state advertisement GMPLS, used OpaqueLSA (for example, see Non-Patent Document 2, 4, 8). Like for IP / MPLS router is set between GMPLS + IP / MPLS node as a PSC-LSP for processing as a normal link, the link between the same and the IP / MPLS node advertising form, e.g., when using OSPP routing protocol, router LSA (e.g., refer to Non-Patent Document 2),

GMPLS十IP/MPLS节点(边緣)具有GMPLS . TED和IP/MPLS . TED, IP/MPLS节点具有IP/MPLS ' TED. GMPLS + IP/MPLS节点(核心)具有GMPLS - TED. GMPLS群内的PSC-LSP在IP/MPLS节点中,和IP/MPLS 间的通常的链路同样对待.在IP/MPLS节点中,不广告由GMPLS的路由协议广告的链路状态. Ten GMPLS IP / MPLS node (edge) having the TED and GMPLS IP / MPLS TED, IP / MPLS node with IP / MPLS 'TED GMPLS + IP / MPLS node (core) having a GMPLS -.... TED group within GMPLS PSC-LSP in the IP / MPLS node, and a general link between IP / MPLS treated the same. in the IP / MPLS node, the advertisement is not GMPLS routing protocol link state advertisement.

实施例4和实施例1比较,因即使不是GMPLS + IP/MPLS节点(边缘),也可以作为IP/MPLS路由器动作,故可以灵活地实施通信工程, Example 4 and Comparative Example 1 embodiment, because if not GMPLS + IP / MPLS node (edge), as may be IP / MPLS router operation, it is possible to flexibly implement communications engineering,

[实施例5】 [Example 5]

在实施例1和实施例4中,当向IP/MPLS网络广告PSC-LSP时, 在使用OSPF路由协议的情况下,使用路由器LSA。 In Example 1 and Example 4, when the IP / MPLS network advertising PSC-LSP, in the case of using the OSPF routing protocol, router LSA. 作为另外的例子也可以使用不使用GMPLS扩展的MPLS参数范闺内的OpaqueLSA(例如, 参照非专利文献8).这时,将GMPLS标莶路径作为IP/MPLS节点中的通常的链路,利用MPLS路由器能处理的OpaqueLSA向IP/MPLS节点广告该链路状态信息,因此,在IP/MPLS网络中》可以实施MPLS通信工程. As another example may be used without the use of an MPLS GMPLS extended parameter range within OpaqueLSA Gui (e.g., refer to Non-Patent Document 8). In this case, the standard Siegesbeckiae path as GMPLS IP / MPLS node in a normal link, using OpaqueLSA MPLS router can handle the link status information to the IP / MPLS node advertising, and therefore, in IP / MPLS networks "Engineering MPLS communication may be implemented.

The difficulties illustrated by the IP / MPLS nodes 71 and 72, GMPLS ten IP / MPLS node (edge) 73 and 74, GMPLS + IP / MPLS node (core) Example 75 constituting the network. in addition, the storm path network 19 is a diagram of the embodiment according to the present embodiment is set trapped order.

使用路由器LSA广告GMPLS网络的C-plane拓朴,已接收到上述广告内容的IP/MPLS节点识別GMPLS网络的C-plane拓朴,在具有该拓朴信息的IP/MPLS节点指定GMPLS网络的C-plane并输出了设定MPLS标签路径的要求的情况下,当由该要求指定的路径上的C-plane 的链路的两端节点存在一致的GMPLS标签路径时,对该GMPLS标签路径分配指定的路径.

通过安装上述功能,从GMPLS网络的外部的IP/MPLS节点经GMPLS 网络,在设定MPLS路径时指定GMPLS网络内郜的路径,这样可以进行珞径的设定. By mounting the above-described functions, the path specified in Gao GMPLS MPLS network when setting up the IP path from an external network GMPLS / MPLS node is GMPLS network, which can be set Luo diameter.

假如,当IP/MPLS节点71指定的路径是GMPLS网络的C-plane 的链路时,GMPLS网络中的GMPLS + IP/MPLS节点(边缘)73和路径上的GMPLS + IP/MPLS节点(核心)75将C-plane的指定改为读出与该C-plane对应的D-plane的链珞(标莶路径),再设定路径。 If, when the specified path 71 IP / MPLS node is a link C-plane of the GMPLS network, GMPLS network GMPLS + IP / MPLS node (edge) GMPLS + IP / MPLS node 73 and the path (core) the C-plane 75 is designated to read out the C-plane of the corresponding D-plane Luo chain (superscript Siegesbeckiae path), the path is reset.

C-plane原本是用来传送控制信号的网络,不一定确保能传送大容量数据的带宽,因此i在本实施例中,具有上述功能,即使从IP/MPLS 节点能见到的GMPLS网络的C-plane被作为路径指定,通过在同一路径上自动地将其换成对应的D-plane,也可以分配用来传送数据的合适的网络. C-plane control network was originally used to transmit signals, are not necessarily guaranteed bandwidth capable of transmitting large amounts of data, so i in this embodiment, having such a function, even if the IP / MPLS in the GMPLS network node can see the C -plane is designated as the path, on the same path by automatically replaced with its corresponding D-plane, it may be assigned to the appropriate network data transmission.

Further, when the subscript Siegesbeckiae MPLS path setting request transmitted sequentially to the IP / MPLS node 72, in response thereto, IP / MPLS node 72 generates an MPLS label path setting request response (the RESV message) transmitted sequentially to the IP / MPLS node 71,
