Preface
In the multi export link environment, the traditional routing gateway products can only implement QoS protection or drainage through the source "IP address + port" mode. As the network applications continue to enrich, for many ports or encrypted applications flow (such as P2P class, network TV class), relying solely on traditional routers to load more tired, no way to start. Enterprises or operators, whether upgraded bandwidth or increased lines, can not get rid of the link is unrelated traffic filled embarrassing situation. The market needs a sophisticated traffic equipment, according to different applications, routing to different links.
In the multi export link environment, the traditional routing gateway products can only implement QoS protection or drainage through the source "IP address + port" mode. As the network applications continue to enrich, for many ports or encrypted applications flow (such as P2P class, network TV class), relying solely on traditional routers to load more tired, no way to start. Enterprises or operators, whether upgraded bandwidth or increased lines, can not get rid of the link is unrelated traffic filled embarrassing situation. The market needs a sophisticated traffic equipment, according to different applications, routing to different links.
XXX company's Flow flow control system introduces the application routing function in time, which makes up for the shortcomings of the traditional routing. Based on the conventional routing function, intelligent routing, intelligent load and intelligent output can be carried out according to the application.
1.Application routing
The application of Flow routing according to specific application traffic routing, the traffic of different types respectively take different links, to ensure the high quality class application link, non guaranteed application link to another. For example: some operators have two export link, a China Unicom, telecom, a XXX enabled application routing, enable Telecom away games with critical applications such as traffic, download and other non critical applications go Unicom line, non critical applications without sacrificing bandwidth, network bandwidth to achieve intelligent application standard.
1.Application routing
The application of Flow routing according to specific application traffic routing, the traffic of different types respectively take different links, to ensure the high quality class application link, non guaranteed application link to another. For example: some operators have two export link, a China Unicom, telecom, a XXX enabled application routing, enable Telecom away games with critical applications such as traffic, download and other non critical applications go Unicom line, non critical applications without sacrificing bandwidth, network bandwidth to achieve intelligent application standard.
There are two ways to apply routing deployment:
1.1 bridge proxy mode
The bridge proxy model is a way of applying an external network card on the basis of a transparent bridge. AA constructs the idea of encapsulating a specific application into a corresponding IP address and then routing the corresponding IP to the specified line with the router. Note the flow direction select uplink, action execution proxy.
1.2 gateway mode
The gateway mode does not need the cooperation of routers, XXX itself can be used as a multi-functional business gateway, and Flow is used as the seven layer routing gateway.
LAN interface for LAN gateway, WAN interface for ISP assigned address (WAN interface has two access methods: static IP access and PPPOE dial-up access), and finally add policy routing.
2.line group load balancing
2.line group load balancing
Line groups, which polymerize multiple lines to amplify bandwidth (small ISP, low cost, lease ADSL aggregation, achieve fiber link effect, can support 500 ADSL convergence). By adding a plurality of export links into a group, the weight of each line is dynamically allocated by setting weights in the group, so as to achieve the purpose of line balancing. Add as follows:
2.1 application routing - line groups - click "number"
2.2 selectively adding lines to the group, and adjust the weight of each line according to the actual situation
2.3 set group parameters, such as group names, types, and load aging adjustments
2.4add policy routing, according to address, port, and application protocol parameters, in the set of routing groups to perform routing actions.
3. summary
Flow provides enhanced network data processing capability, improve network flexibility and availability of a high performance price ratio, different from the traditional load balancing, load balancing products is the traditional automatic load balancing based on traffic link, and through the Flow configuration strategy is realized according to application protocol flow load sharing, summary it has the following advantages:
1, based on application and destination address combination, according to time scheduling, to ensure real-time application
1, based on application and destination address combination, according to time scheduling, to ensure real-time application
2, determine traffic according to critical applications and non critical applications, and drive different link exits, thereby ensuring user experience and fluency for critical applications
3, the number of low cost link (such as multiple ADSL) polymerization of one or more virtual high-speed link, save cost and make the best use of it, to maximize the bandwidth potential
