Specific embodiment
To keep the purposes, technical schemes and advantages of the embodiment of the present disclosure clearer, below in conjunction with the embodiment of the present disclosure The technical solution in the embodiment of the present disclosure is clearly and completely described in middle attached drawing, it is clear that described embodiment is only It is disclosure a part of the embodiment, instead of all the embodiments.The disclosure being usually described and illustrated herein in the accompanying drawings is real The component for applying example can be arranged and be designed with a variety of different configurations.Therefore, below to the disclosure provided in the accompanying drawings The detailed description of embodiment is not intended to limit claimed the scope of the present disclosure, but is merely representative of the selected reality of the disclosure Apply example.Based on embodiment of the disclosure, those skilled in the art institute obtained without making creative work There are other embodiments, belongs to the range of disclosure protection.
In view of being provided in the scheme across data center's interconnection in the related technology, all data messages of data center are equal It needs to be handled by the edge device (Edge Device, ED) of the data center, the processing pressure of ED is larger.
In order to alleviate the processing pressure of ED, a kind of double ED load balancing technologies are provided in the related technology, as shown in Figure 2 Double ED networking schematic diagrams, can each data center edge dispose two ED (such as ED1 of the first data center deployment and ED2 an equipment), and by two ED is invented, in this way, ED can establish tunnel using virtual IP address and VTEP1, distal end ED, then Using the equivalent route mechanism of Underlay network, VTEP2 can will be sent to the flow of ED virtual IP address while be sent to two ED, To realize load balancing.
As shown in Fig. 2, the edge of the first data center and the second data center is deployed with two ED, in the first data For the heart, two ED (i.e. ED1 and ED2) can pass through Underlay network and opposite end data center (the second data center) ED establish connection.Such as when the ED1 of the first data center data center interconnection (Data Center Interconnect, DCI when) the Underlay network of side (corresponding transmission link DC1-1) breaks down, due to being assisted on ED1 for establishing borde gateway Discuss too net Virtual Private Network (the Ethernet Virtual Private of (Border Gateway Protocol, BGP) Network, EVPN) state of loopback mouth in neighbours and tunnel is always to open (up), so Interior Gateway Protocol (Interior Gateway Protocol, IGP) routing always exists, and data center's internal network can not perceive the failure again, In this way, VTEP (expansible Virtual Local Area Network endpoint of a tunnel (the VXLAN Tunnel End in the first data center Point, VTEP) VTEP2 of (i.e. VTEP 1) into the second data center when sending datagram, can still forward the stream of VTEP 1 ED1 is measured, but ED1 is to the outlet of the second data center failure at this time, the relevant technologies are due to lacking corresponding troubleshooting Mechanism is unable to satisfy data center and transmits to data in this way, all flows for being forwarded to this ED1 will be all dropped under this state The requirement of integrality.
In order to solve above-mentioned technical problem present in the relevant technologies, the embodiment of the present disclosure provides a kind of data message biography Transmission method, apparatus and system, with can ED break down when, it is ensured that flow forwarding do not lose under the premise of, further ensure that The efficiency of flow forwarding.
Data message transmission method and device that the embodiment of the present disclosure provides in order to facilitate understanding, first to a kind of reality of the disclosure The data-message transmission system for applying example offer is illustrated.
The embodiment of the present disclosure provides a kind of data-message transmission system, which is applied to different numbers According between center data transmission, wherein each data center include at least the first ED and the 2nd ED, the first ED and the 2nd ED it Between establish have edge device interface extensible Virtual Local Area Network (ED Interface Virtual eXtensible Local Area Network, EDI-VXLAN) tunnel；
First ED, for if it is determined that the transmission link of itself generates failure, then being sent out transmitting terminal using the tunnel EDI-VXLAN The data message forwarding sent is to the 2nd ED；And the routing for reaching the corresponding next-hop of transmission link from the first ED is set to not Available mode；
2nd ED, for receiving and sending the data message of the first ED forwarding；And it is transmitted determining to reach from the first ED When the routing of the corresponding next-hop of link is unavailable, routing update information is sent to transmitting terminal；Wherein, routing update information is used for Indicate that the IP address of the 2nd ED is updated to real ip address from virtual ip address by transmitting terminal.
Here, precisely in order to solving when the transmission link of ED itself generates failure, all flows for being forwarded to this ED are all The problem of by being dropped to be unable to satisfy data center the requirement to data transfer integrity, the embodiment of the present disclosure is just first The tunnel EDI-VXLAN has been pre-established between ED and the 2nd ED, it, can be with to ensure when the transmission link of the first ED generates failure Data message forwarding transmitting terminal sent using the tunnel EDI-VXLAN is to the 2nd ED.
Here, the entire data-message transmission system institute when the transmission link of the first ED generates failure is mainly considered Corresponding network topology structure will change therewith, the variation of network topology structure will so that data message from source address (such as The BGP address 1.1.1.1 of VTEP1 shown in Fig. 3) to be sent to destination address (the BGP address 6.6.6.6 of VTEP2 as shown in Figure 3) right The routing table answered also changes therewith.
Learn to need certain time up to stabilization however, routing table re-establishes transmission and arrives again, it is stable reaching Before (i.e. routing convergence), still can some data traffic loads to there are the first ED of transmission link failure, at this moment, first ED generates failure in the transmission link that data forwarding layer has perceived itself, therefore can enable the EDI- pre-established The tunnel VXLAN, and flow forwarding is carried out using the tunnel EDI-VXLAN, thus avoid when the transmission link of ED generates failure, All flows for being forwarded to this ED1 will all be dropped to be unable to satisfy asking for requirement of the data center to data transfer integrity Topic.
The first ED and the 2nd ED is carried out it is worth noting that the above-mentioned tunnel EDI-VXLAN can be a kind of of definition The characteristics of VXLAN tunnel type of EVPN network connection, the tunnel type is can both to forward expansible Virtual Local Area Network The network flow in the tunnel (Virtual eXtensible Local Area Network, VXLAN), and can forward expansible The network in Virtual Local Area Network data center interconnection tunnel (VXLAN Data Center Interconnect, VXLAN-DCI) Flow.In the embodiment of the present disclosure, while establishing the tunnel EDI-VXLAN, it can also increase between the first ED and the 2nd ED One direct connected link carries the tunnel EDI-VXLAN defined above using the direct connected link.In addition to this, in order to support double ED The automatic identification of (such as the first ED and the 2nd ED) and the automatic foundation in the tunnel EDI-VXLAN, the embodiment of the present disclosure can also be to more Protocol boundary gateway protocol (Multi Protocol-Border Gateway Protocol, MP-BGP) Layer 2 virtual private network Network (Virtual Private Network, VPN) EVPN address family is extended, and increases the subaddressing race of EVPN ED, the ground newly Location race can carry the virtual ip address attribute of the true next hop address attribute of BGP and double ED, pass through identification neighbours between double ED The two attributes carried are compared with being locally configured, it is determined whether using neighbours ED as oneself ED group member (GROUP).
Based on above-mentioned deployment, the first ED is when the transmission link that data forwarding layer has perceived itself generates failure, just The tunnel EDI-VXLAN can be enabled, and can use the extended method of above-mentioned MP-BGP L2VPN EVPN address family for direct-connected chain Road corresponds to destination address of the real IP of next-hop as the tunnel EDI-VXLAN, so as to using the tunnel EDI-VXLAN into The forwarding of row flow.
With the propulsion of fault time, the first ED can also perceive link failure in upper layer, at this point, this first The routing for reaching the corresponding next-hop of transmission link from the first ED can be set to down state by ED.In the embodiment of the present disclosure, First ED, which can be directly arranged by routing, be set to above-mentioned routing unavailable, can also be transmitted by deleting to reach from the first ED The routing iinformation of the corresponding next-hop of link is to realize the not available setting of routing.Which kind of either above-mentioned implementation, is setting After the completion of setting, instruction can be generated and route not available route withdraw message, so as to other equipment (such as the 2nd ED, transmitting terminal Deng) know above-mentioned routing unusable state, and can timely make a response.
For the 2nd ED, when determining unavailable from the routing that the first ED reaches the corresponding next-hop of transmission link, Routing table information can be refreshed, and transmitting terminal will be used to indicate, the IP address of the 2nd ED is updated to practical IP from virtual ip address The routing update information of address is sent to transmitting terminal, so that transmitting terminal can be according to after the update that the transmitting terminal reaches the 2nd ED Routing iinformation data message transmission.Here, the 2nd ED can route not available route withdraw receiving the first ED instruction Message is unavailable to determine the routing for reaching the corresponding next-hop of transmission link from the first ED.
For transmitting terminal, when determining unavailable from the routing that the first ED reaches the corresponding next-hop of transmission link, The first ED can be specified can not carry out data transmission to the corresponding next-hop of transmission link, can refresh the routing of itself at this time Outlet, and the routing update information sent according to the 2nd ED carries out the transmission of data traffic to the 2nd ED.That is, in routing convergence Later, data traffic directly can be forwarded to the 2nd ED, Jin Erti by the data-message transmission system that the embodiment of the present disclosure provides Rise the efficiency of transmission of data traffic.Similarly, transmitting terminal can also route not available route withdraw receiving the first ED instruction Message is unavailable to determine the routing for reaching the corresponding next-hop of transmission link from the first ED.
In the embodiment of the present disclosure, transmitting terminal can be the VTEP that data center includes, and can also be for connecting different numbers According to the core equipment at center, next above-mentioned two situations are illustrated respectively.
First aspect: transmitting terminal is the VTEP that data center includes, at this point, between VTEP and the first ED and the 2nd ED respectively Foundation has the tunnel VXLAN.It can also include for connecting different numbers in the data-message transmission system that the embodiment of the present disclosure provides According to center core equipment when, the core equipment can between the first ED and the 2nd ED respectively establish have the tunnel VXLAN-DCI.
The tunnel VXLAN, the tunnel EDI-VXLAN and the tunnel VXLAN-DCI based on above-mentioned foundation, VTEP can be by data Message is forwarded to core equipment.
For VTEP: on the one hand, VTEP can obtain data message, the datagram that will acquire using the tunnel VXLAN Text is forwarded to the first ED, so that the first ED receives the data message of VTEP forwarding；On the other hand, which can also receive After the routing update message that first ED instruction routes not available route withdraw message and the 2nd ED is sent, sent according to the 2nd ED Routing update message the address of the 2nd ED is updated to real ip address from virtual ip address, so as to directly by VTEP's Data traffic is forwarded to the 2nd ED so that data traffic is forwarded to core equipment by the 2nd ED, and then promotes the biography of data traffic Defeated efficiency.
It is worth noting that since the address in relation to the 2nd ED in routing iinformation has been updated to reality from virtual ip address IP address, at this point, the tunnel the VXLAN needs between the VTEP and the 2nd ED that establish dependent on address information re-establish, that is, VTEP can re-establish the tunnel VXLAN between the 2nd ED based on routing update information, and utilize the VXLAN re-established Tunnel is by data message forwarding to the 2nd ED.
For the first ED, the first ED can determine itself transmission link generation failure between core equipment When, the VTEP data message sent is encapsulated as the first encapsulation of data message convenient for EDI-VXLAN tunnel transmission, and utilize First encapsulation of data message is forwarded to the 2nd ED by the tunnel EDI-VXLAN.
For the 2nd ED, on the one hand, the 2nd ED can receive the first encapsulation of data message of the first ED forwarding, to first Encapsulation of data message is decapsulated, and the first decapsulation data message is obtained；On the other hand, the 2nd ED can also be by the first solution The second encapsulation of data message that encapsulation of data message is encapsulated as convenient for VXLAN-DCI tunnel transmission, will using the tunnel VXLAN-DCI Second encapsulation of data message is forwarded to core equipment.
Above-mentioned data-message transmission system in order to facilitate understanding, spy lift a specific example and are illustrated.
As shown in figure 3, two different data centers are respectively the first data center and the second data center, in the first data Pericardium includes the first ED group (ED1 and ED2) and VTEP1, be respectively present between VTEP1 and ED1 and ED2 VXLAN-1 link and VXLAN-2 link is respectively present DCI-1 link and DCI-2 link between core equipment P and ED1 and ED2；Second data center Including the 2nd ED group (ED3 and ED4) and VTEP4, data transmission is realized by core equipment P between two ED groups.Assuming that data The routing direction of flow is the VTEP2 from the data center of VTEP1 to second of the first data center.
When DCI-1 link (transmission link between corresponding first ED and core equipment) breaks down, VTEP1 is arrived The data traffic of VTEP2 can still be sent to ED1 in a manner of load balancing, at this point, ED1 forwarding plane has perceived DCI-1 Failure, will can star the tunnel EDI-VXLAN as over run tunnel forward the flow from VTEP1, flow reach ED2 after Decapsulation is executed, ED2 utilizes the tunnel the VXLAN-DCI continuation transmitting data flow amount between the ED2 and core equipment after encapsulating again To core equipment, data traffic is forwarded to the 2nd ED group again for core equipment so that the 2nd ED group continues transmitting data flow amount extremely VTEP2。
After the upper-layer protocol of ED1 and the second data center perceive DCI-1 link failure, ED1 can delete second The EVPN for the VTEP2 that data center synchronizes is routed, it can the corresponding next-hop of transmission link will be reached from the first ED (i.e. Core equipment) routing be set to down state, while instruction can also be routed not available route withdraw message and be sent to VTEP1 and ED2, ED2 refresh routing iinformation, i.e., it is true route next jump address (i.e. virtual ip address) 1.2.3.4 to be changed into BGP Real next hop address (i.e. real ip address) 3.3.3.3, in this way, data traffic can be from after VTEP1 refreshes routing outlet VTEP1 directly arrives ED2 and continues to forward.
Second aspect: transmitting terminal is the core equipment for connecting different data center, at this point, core equipment and first Establishing respectively between ED and the 2nd ED has the tunnel VXLAN-DCI.When the data center can also include VTEP, the VTEP Can establish respectively between the first ED and the 2nd ED has the tunnel VXLAN.
The tunnel VXLAN, the tunnel EDI-VXLAN and the tunnel VXLAN-DCI based on above-mentioned foundation, core equipment can incite somebody to action Data message forwarding is to VTEP.
For core equipment: on the one hand, core equipment can need to be transmitted to a data center receiving After data message, using the tunnel VXLAN-DCI by the first ED of received data message forwarding to the data center, so that first ED receives the data message of core equipment forwarding；On the other hand, which can also receive the first ED instruction routing After the routing update message that not available route withdraw message and the 2nd ED are sent, according to the routing update message of the 2nd ED transmission The address of 2nd ED is updated to real ip address from virtual ip address, so as to directly turn the data traffic of core equipment The 2nd ED is sent to so that data traffic is forwarded to VTEP by the 2nd ED, and then promotes the efficiency of transmission of data traffic.
It is worth noting that since the address in relation to the 2nd ED in routing iinformation has been updated to reality from virtual ip address IP address, at this point, the tunnel VXLAN-DCI between the core equipment and the 2nd ED established dependent on address information needs to build again It is vertical, that is, core equipment can re-establish the tunnel VXLAN-DCI between the 2nd ED, and benefit based on routing update information With the tunnel VXLAN-DCI re-established by data message forwarding to VTEP.
