It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in this description belong to the protection scope of this document.
An application scenario of the present specification is exemplarily described below with reference to fig. 1.
In one application scenario, comprising: gateway 101, switch 102, service platform 103, firewall 104 and public network 105, wherein:
the gateway 101 performs distribution processing on the full traffic through the switch 102, including: on one hand, the effective service flow is distributed to the router of the service platform 103; referring to fig. 2, the Service platform 103 includes an integrated Gateway (ISG) Router (Router, RT) 1031, an ISG Firewall (FW) 1032, an ISG Switch (Switch, SW) 1034, and an ISG Load Balancer (LB) 1033, where the ISG RT 1031 receives traffic from the Gateway 101 and transmits the traffic through the ISG FW1032 and the ISG SW 1034; on the other hand, the invalid traffic is shunted to the public network 105 through the firewall 104.
The Gateway 101 may refer to a System Architecture Evolution Gateway (SAEGW) of a core Network, or may refer to a Public Data Network Gateway (PGW); the switch 102 may refer to a Customer-side router connected by a service provider, preferably a Customer Edge router/switch (CE); the firewall 104 is preferably a Gi/SGi firewall, a Gi/SGi interface is an interface between GPRS and an external packet data network, a Gi interface is an interface between GGSN and PDN, and an SGi interface is an interface between PGW and PDN; the service platform refers to a specific platform for processing service traffic, and service platforms corresponding to different services may be different, and a toolbar TOOL BAR platform is commonly used.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
Fig. 3 is a flowchart of a flow splitting processing method provided in an embodiment of this specification, which may be executed by the ISG RT router 1031 in the service platform 103 in fig. 3, where a route between the router and the gateway 101 is configured as a dynamic route, and the method specifically may include the following steps:
the routing configuration information refers to dynamic routing configuration, and may be based on a distance vector routing protocol and a link state routing protocol, where a RIP protocol and an OSPF protocol are representative, and for convenience of description, the OSPF protocol is taken as an example to be described later.
it should be noted that, referring to fig. 4, the first dynamic routing manner of step 204 may be:
the network type network-type of the Open Shortest Path First (OSPF) of the router and the gateway are both configured as a Point-to-Point (P2P) mode; the router establishes OSPF neighbor relation with the gateway, and the source address of the tunnel of the router is configured as an interface IP; and issuing the specified service traffic route to the gateway through the OSPF. Assuming that the specified traffic flow route is a TOP-N ip detail route, the first dynamic routing manner may specifically be as follows:
the method comprises the steps that the router comprises a main router and a standby router, and the OSPF network types of the routers are all configured to be P2P; the main router, the standby router and the gateway establish OSPF neighbor relations, and the OSPF routing issuing priority corresponding to the main router is greater than the OSPF routing issuing priority corresponding to the standby router.
Then, in a normal state, the routing configuration information may be configured on the main router, and the main router issues TOP-N ip detailed routing to the gateway in a 32-bit host routing manner through OSPF; when the link between the main router and the gateway is abnormal, the cost value of the OSPF is increased, and the TOP-N ip detailed route can be issued to the gateway by the standby router through the OSPF, namely the TOP-N route is issued to the PGW from the GRE router standby equipment; the cost value refers to the cost of reaching the destination address indicated by a certain route.
Referring to fig. 5, the second dynamic routing manner of step 204 may be:
the OSPF network types of the router and the gateway are respectively configured as P2P and point-to-multipoint master stations (point 2multiple point, P2MP); the router establishes OSPF neighbor relation with the gateway, and the source address of the tunnel of the router is configured as a loopback address; and the router distributes the specified service traffic route to the gateway through OSPF. Assuming that the designated traffic flow route is a TOP-N ip detail route, the second dynamic routing manner may specifically be as follows:
the router comprises a main router and a standby router, and the OSPF network types of the routers are configured to be P2P; when the link between the main router and the gateway is normal, the loopback address only survives active in the main router, an OSPF (open shortest path first) neighbor relation is established between the main router and the gateway, the TOP-N ip detailed route can be configured in the main router, and the main router informs the TOP-N ip detailed route to the PGW gateway through OSPF (open shortest path first) in a 32-bit host routing mode;
when the link between the main router and the gateway is abnormal, the loopback address survives in the standby router, and the standby router and the gateway establish OSPF neighbor relation; the TOP-N ip detail route can be configured at the main router and the standby router, so that the standby router can inform the PGW gateway of the TOP-N ip detail route in a 32-bit host routing mode through OSPF.
Referring to fig. 6, the third dynamic routing manner of step 204 may be:
the OSPF network types of the router and the gateway are both configured to be P2P; establishing OSPF neighbor relation with the gateway, configuring the source address of the tunnel of the router as a loopback address; and issuing the specified service traffic route to the gateway through OSPF. Assuming that the specified traffic flow route is a TOP-N ip detail route, the third dynamic routing manner may specifically be as follows:
the router comprises a main router and a standby router, and the OSPF network types of the routers are all configured as P2P;
when the link between the main router and the gateway is normal, the loopback address survives the main router; a service platform side tunnel starts keepalive, adjusts the single-pass state of the tunnel from the standby router to the gateway to be closed, and establishes an OSPF (open shortest Path first) neighbor relation between the main router and the gateway; TOP-N ip detailed routing can be configured in the main router so as to inform the PGW gateway of the TOP-N ip detailed routing through OSPF in a 32-bit host routing mode;
when the link between the main router and the gateway is abnormal, the loopback address survives the standby router, the single-pass state of the tunnel from the standby router to the gateway is adjusted to be open, and the standby router and the gateway establish an OSPF neighbor relation; the TOP-N ip detail route can be configured at the standby router so as to inform the PGW gateway of the TOP-N ip detail route in a 32-bit host route mode through OSPF by the standby router.
The embodiment of the present specification shows three specific implementations of the step 204. Of course, it should be understood that step 204 may also be implemented in other ways, and this is not limited by this embodiment.
And step 206, receiving the specified service flow distributed by the gateway.
The following takes a specific toolbar service platform as an example to exemplarily explain the effects of the embodiments in this specification:
because the enhanced WAP gateway and the toolbar service can be developed only in http browsing traffic of users, the traffic occupies a small proportion in the total traffic, and the video picture traffic occupying a larger proportion in the total traffic is completely ineffective for developing the service. Therefore, by implementing the ISG GRE Router distribution scheme and subsequent optimization, only TOP 1000ip of http browsing services is distributed to the enhanced WAP gateway, the access flow is greatly reduced to 11.9% of the full flow, and about 96% of users can be covered; shunting TOP 500ip to the enhanced WAP gateway reduces the incoming traffic to 5.8% of full traffic, but still covers more than 87% of users, see table below:
to sum up, in the embodiments of the present description, a dynamic routing offloading scheme between a router and a gateway is configured to screen out high-value traffic and offload the high-value traffic to a service platform, and most of invalid traffic is communicated to a public network, so as to reduce consumption of a transmission bandwidth and the service platform; moreover, the dynamic routing is issued on the service platform side digital communication equipment (namely, ISG router), so that the security is higher, and even if a fault occurs, only the service platform is influenced, and other service platforms in the whole network cannot be influenced; moreover, the flow is shunted according to the IP without charging processing on the service platform side, so that the conflict with the content charging on the SAEGW gateway is avoided; moreover, the dynamic route is issued at the rear end centralized node side, and compared with the configuration of route details at the front end scattered SAEGW/CE nodes, the workload is greatly reduced.
In another possible embodiment, a plurality of disaster recovery mechanisms are also proposed, and referring to fig. 1 and fig. 2, specific examples may be as follows:
example 1 Single-sided failure of Integrated gateway data communications device
In the case of a single-side failure of the data communication device, if the ISG primary router 1031 fails, the device will automatically switch to the standby side disaster recovery, i.e., the ISG standby router (1031', not shown in the figure). If automatic switching cannot be achieved in an extreme case, a scheme of manual switching or direct closing of a tunnel between a gateway and a router is adopted for disaster recovery, and all traffic is directed out of the firewall 104.
Example 2, simultaneous failure of active/standby firewalls or simultaneous failure of active/standby router 1031 (1031') on the service platform side
The active and standby firewalls fail simultaneously or the active and standby routers fail simultaneously, OSPF will automatically fail under normal circumstances, and all traffic is directed out of the firewall 104. In an extreme case, a scheme of manually closing the tunnel is adopted for disaster recovery (the tunnel is closed preferentially from the integrated gateway side, and if the integrated gateway side cannot be closed in a special case, the tunnel is closed by the PGW side), and all traffic is directed from the firewall 104.
Example 3, the primary and standby switches 1034 (1034 ') fail simultaneously or the primary and standby load balancing areas 1033 (1033') fail simultaneously
The primary and secondary switches and the primary and secondary LB simultaneously fail, the PSPF does not automatically fail, and only a scheme of manually closing the tunnel is used for disaster recovery (the primary switch and the secondary switch are preferably closed from the integrated gateway side, and if the integrated gateway side cannot be closed under a special condition, the primary switch and the secondary switch are closed from the PGW side), and all the traffic is directly sent out from the firewall 104.
The embodiments of the present specification show a plurality of specific examples of the disaster recovery mechanism described above. Of course, it should be understood that the disaster recovery mechanism may also be implemented in other manners, and the embodiment of the present application is not limited thereto. Based on this, the embodiment of the present specification makes more flexible and efficient disaster recovery means based on the dynamic routing manner disclosed in the embodiment corresponding to fig. 3, so as to achieve the purpose of automatic disaster recovery under a general fault condition and manual and fast disaster recovery under an extreme fault condition.
