Member's every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Multiprotocol label switching (MPLS, Multi-Protocol Label Switching) is a kind of in open communication
It is online to utilize label guidance data high-speed, the technology of high efficiency of transmission.MPLS uses label distribution technology, and IP address is mapped as letter
Single label with regular length, MPLS network carry out data forwarding using label.
Section Routing Protocol (SR, Segment Routing) is a kind of source-routed protocol, is referred to by source node for application message
Determine path, and path integration is encapsulated into heading at an orderly Segment list, the intermediate node in path only needs
It is forwarded according to the path specified in heading.
EVPN (Ethernet Virtual Private Network) is a kind of VPN for realizing network double layer intercommunication
Technology.By extend bgp protocol NLRI, increased the BGP EVPN route-type of several types newly, for different websites it
Between notice host MAC Address and IP address information.
Referring to Fig. 1, Fig. 1 is the flow diagram for the service bearer method that one embodiment of the application provides, this method master
Want the following steps are included:
S101, Label Forwarding Information Base is established using IGP agreement, the label in the Label Forwarding Information Base includes the node of device node
Label and adjacent label；
Node label (Prefix/Node Segment) is the label distributed for equipment itself, an equipment i.e. one section
Point, label are globally unique.Each equipment has the MPLS label range of each self-supporting, and the equipment for supporting SR need to reserve one section of label segment
As global node label SRGB (Segment Routing Global Block).Equipment extends notice SRGB's by IGP
Label segment limit and the global I ndex of oneself, the corresponding node label of each device node is SRGB+Index.
Adjacent label (Adjacent Segment) indicates the single-hop path of certain link in equipment, and only equipment is local for label
Effectively.Each equipment extends the adjacent label of notice by IGP to oneself the adjacent equipment of a jump, or passes through SDN controller
Directly label distribution is carried out for each of the links in the domain SR.
S102, when receiving message, label stack is specified on the source node of message according to adjacent label；
In SR agreement, path be indicated by an orderly segment list (being label stack in MPLS), and by
It is encapsulated in heading and is forwarded, therefore, the path SR is no longer dependent on the signaling protocol (LDP or RSVP-TE) of hop-by-hop to build
It is vertical, but a label stack is directly specified by message source node or controller, intermediate forwarding device only need to be by label
The information of stack is forwarded, very simply.
The application in one embodiment, before step S102 further include:
According to SDN path computation result, message forwarding path is determined；
According to the message forwarding path, relevant device node is searched；
The adjoining label of the device node is searched in the Label Forwarding Information Base.
In the present embodiment, such as since R1 to the message of R6, process flow is as follows:
First node (R1): according to SDN path computation result, determine that packet route is figure Green line.For example, according to neighbours
Label information stamps [204,405,506] label stack at R1.
Forward node (R2, R4, R5): pop-up stack top label selects outbound to be forwarded according to this label.
Tail node (R6): it is forwarded according to common message normal flow.
S103, the stack top label for obtaining the label stack, and search node label node identical with the stack top label；
S104, the node is forwarded the packet to.
The application in one embodiment, forward the packet to the node include: search reach the node most
Short path；According to the shortest path, which is sent to the node.
As shown in Fig. 2, R6 node is 6, SRGB since 7000 by the Index that IGP extension has issued oneself, then R6
Node label is 7006.Therefore when other equipment receive the message that stack top label is 7006 in net, it directly can search one and arrive
Message is sent to R6 by the routing shortest path of R6.
To the message of R6 since R1, process flow is as follows:
First node (R1): according to SDN path computation result, determine that message needs that node label stack 7006 is added by R6.
Forward node (R2): it is consistent with common MPLS Message processing, Tag switching processing is carried out, label remains as 7006.
The last two jump (R3): when such as IGP advertisement SR information, notice needs to carry out the last two jump pop-up, then saves herein
Click through row label pop-up.
Tail node (R6): it is forwarded according to common message normal flow.
In the embodiment of the present application, Label Forwarding Information Base is established using IGP agreement, the label in the Label Forwarding Information Base includes setting
The node label of slave node and adjacent label specify mark according to adjacent label when receiving message on the source node of message
Stack is signed, the stack top label of the label stack is obtained, and search node label node identical with the stack top label, which is forwarded
The node is given, simplifies the design and management of network, is quickly obtained network service, optimizes the performance of whole network.
For EVPN, control layer is MP-BGP, and EVPN can regard the application constructed on MP-BGP as.Such as figure
The realization of 3EVPN, the write-in of MAC forwarding table in the transmitting and MAC-VRF that control layer realizes MAC forwarding information.Specifically,
It is exactly the MAC Address of CE1, how is sent to PE2, and then PE2 is allowed to receive the Ethernet that purpose MAC is CE1 MAC Address
When Frame, it is known that PE1 should be sent to by Tunnel.After but data Layer realize CE2 how ping to CE1.Following base
The application is illustrated in EVPN:
It includes: 1, CE1- > PE1 that the MAC Address of control layer CE1, which is sent to PE2,；2, PE1- > PE2/MP-BGP.
1, CE1- > PE1
Usually or by data Layer mac learning is carried out between CE-PE.That is, PE1 is needed through parsing CE1 hair
The data packet come, in the MAC forwarding table for reading source MAC therein, and being recorded in MAC-VRF.These usual data packets
It is first data packet, such as DHCP, ARP etc. that equipment issues.Using it is this it is traditional by the way of, first is that CE do not need be concerned about SP
The realization of network, the other is CE equipment can be preferably compatible with.MAC-VRF has also corresponded to a RD (Route
) and one group of RT (Route Target) Distinguisher.RD is used to distinguish the information of EVPN example, and RT is used to filter the road MAC
By.This had detailed introduction when introducing BGP/MPLS L3 VPN before, did not just say here.It is good, the MAC in relation to CE1
Forwarding information has reached PE1, is specifically the MAC-VRF reached in PE1.
2, PE1- > PE2/MP-BGP
MAC forwarding information transmitting between PE is to be carried out by MP-BGP, that is, inside EVPN, MAC forwarding is believed
Breath is transmitted by control layer.This is EVPN and VPLS most crucial difference.Because inside EVPN being SP network, SP think why
Object for appreciation is ok.MP-BGP is the extension of BGP-4, and correcting is multiple, and newest version is defined by RFC4760.MP- in EVPN
A BGP substantially still IBGP.Present PE1 has the MAC forwarding information of CE1, need to do is to be packaged into the transmitting of BGP data
To PE2.EVPN first defines the address family (AFI 25, SAFI70) of oneself in MP-BGP.Under this address family, but it is fixed
Justice different NLRI (Network Layer Reachability Information).
This MAC/IP route is sent PE2 by PE1.As the effect in L3 VPN, PE2 passes through MAC/IP
The RT of the RT of band and the MAC-VRF of itself are matched in route, navigate to which MAC-VRF receives this routing.Due to
There may be multiple forwarding tables by MAC-VRF, it is thus possible to need ET ID also to determine which forwarding table routing is specifically written to.
So far, MAC forwarding information has been write PE2 by MP-BGP by PE1.MAC-VRF on present PE2 knows
, corresponding MAC should be forwarded on PE1.
Data Layer CE2 ping to CE1 includes: 1, CE2- > PE2；2, PE2- > PE1；3, PE1- > CE1.
1, CE2- > PE2
Before ping, CE2 is not because know the MAC Address of CE1, it is necessary to first send ARPrequest, pass through CE1's
The MAC Address of IP address inquiry CE1.PE2 said before can configure ARP proxy, such PE2 receive ARP request it
Afterwards, directly the MAC Address of CE1 is placed in ARP response and is passed back to CE2.CE2 takes MAC Address, assembles Ethernet
Ping packet is sent PE2 by Header.
2, PE2- > PE1
The MAC-VRF of PE2 has recorded the forwarding information of MAC, therefore PE2 knows, purpose MAC is CE1 MAC
Ethernet Frame should be sent to PE1.This part PE2- > PE1 is actually to run on SP network.
3, PE1- > CE1
The ping packet with VPN Label that PE1 is received.This VPN Label is that PE1 by MP-BGP is sent to PE2.Cause
This, PE1 necessarily knows this VPN Label should correspond to which MAC-VRF of oneself.So VPN Label is stripped,
Ping coating is sent to corresponding MAC-VRF, by the MAC forwarding table in reading MAC-VRF, is sent to corresponding port, that is,
CE1.In this way, CE2ping has arrived CE1.
The application is illustrated below based on SR technology:
SR is a provenance route technology, by head node maintenance strategy state, the intermediate node Maintenance free plan of forward-path
Slightly state, greatly simplifying network is complexity signaling protocol needed for maintenance strategy status information.It is extended by IGP and BGP to complete
Net floods the segment marks such as prefix, node, link label (segment identifier, SID) information, is not necessarily to additional signaling protocol
(such as LDP, RSVP-TE) distributes label.SR technology inherits the advantage of MPLS technology well, but can adapt to IPv6,
The development of the technologies such as SDN provides a kind of flexible and efficient control means for SD-WAN network, has and is expanded using simple, easy
The characteristics of exhibition, preferably realizes flow scheduling and path optimization, provides the network service of application drive, ensures key business matter
Amount simplifies the design and management of network, is quickly obtained network service, optimizes the performance of whole network.
From the point of view of controlling plane, SR is the simplification and optimization to existing MPLS, and network only needs support IGP agreement, no longer
It needs to dispose LDP or RSVP-TE agreement, is in particular in the following aspects:
1. the distribution and distribution of label: traditional MPLS network needs the protocol synchronizations such as LDP and distributes the mark of each node
Information is signed, SR no longer needs LDP agreement, it is only necessary to synchronize by the SR extension of IGP agreement (ISIS or OSPF), or by controlling
Device processed is uniformly allocated and issues, and enormously simplifies the number of protocols of equipment operation.
2. the foundation of Label Forwarding Information Base: same tradition MPLS needs to form label turn after distributing label by LDP agreement
It delivers, and the scale of Label Forwarding Information Base can be very big, and SR only needs IGP agreement that can complete building for Label Forwarding Information Base
It is vertical, and it is very easy to extension, also very little, entry number are N (node label quantity, generally the whole network number of nodes)+A to scale
(adjacent label data, generally equipment interface quantity).
3. the mark and foundation in path: in an mpls network, the path that a message passes through is LSP, by specified by hand
Or established using LDP, RSVP-TE agreement hop-by-hop dynamic, it is extremely complex and be difficult to safeguard.In SR agreement, path is by one
Orderly segment list (being label stack in MPLS) indicates, and is encapsulated in heading and is forwarded, therefore, SR
Path is no longer dependent on signaling protocol (LDP or RSVP-TE) Lai Jianli of hop-by-hop, but directly by message source node or control
Device specifies a label stack, and intermediate forwarding device need to be only forwarded by the information of label stack, very simply.
SR advantage:
1, the agreement towards SDN architecture design has merged equipment autonomously forwarding and has concentrated the advantage of programming Control, Neng Gougeng
The network of good realization application drive.Meanwhile can naturally support traditional network and SDN network, and compatible existing equipment, ensure ne
Network smooth evolution.
2, simplify equipment and control plane, reduce Routing Protocol quantity, simplify operation management, cut operating costs；Label turns
Deliver simple, be easy extension, scale also very little, the forwarding table number safeguarded in an equipment be N (node label quantity, generally
The whole network number of nodes)+A (adjacent label data, generally equipment interface quantity), and traditional MPLS network is then N^2.
3, the scenes such as extensive deployment scenario, including backbone network, DCI network and DC network are supported, and can be propped up simultaneously
Hold MPLS and IPv6 network.
4, the functions such as TE, FRR, OAM can be realized in a simpler manner, to simplify the design and management of network, quickly
Network service is obtained, the performance of whole network is optimized.
