Abstract
The present invention is adapted to network technologies and the field of communications, and provides a method for routing data streams in a network with respect to multiple different operators. In order to overcome deficiency of conventional load balancing, the present invention provides the following steps: performing a proper arithmetical operation via two elements, i.e., a source IP address and a target IP address, to form a SESSION; when performing routing for link load balancing, using the SESSION as a unique calculation standard; defining the two elements as a basic condition for one SESSION, and adding a certain hash algorithm to establish a connection for the SESSION in an internal storage; when the connection does not exist in the internal storage, performing dynamic routing for the SESSION and writing a routing result in an item of the internal storage of the SESSION in the form of a tag; positioning subsequent messages to the SESSIION via HASH; and then routing according to the tag. The solution is a compromised solution based on a conventional strategy routing and five-element load balancing, keeps a high efficiency, and is also simple at the same time.
Description
Technical field
The present invention is suitable for network technology and the communications field, provides a kind of for when having multiple different operators, the data flow in network is carried out to the method for routing.
Background technology
At present, there is multiple operator providing Internet exportation in China, as UNICOM, telecommunications, movement, education network etc.Along with the development of network technology, a lot of enterprise network can access many different operator's links, after connecting these links, if along with and what come is how to select best link to carry out the hot standby and balancing link load of link.This method provides a kind of new link load route selecting method on traditional load balancing basis, efficiently solves the balanced masty problem of the conventional load such as load balancing, redundancy, session maintenance.Traditional method has following several:
1 policybased routing.Advantage is simple, and shortcoming is when circuit is fully loaded time, still can send data on circuit, cause circuit overload.
2 based on the balancing link load of five elements.Be a little comparatively balanced, shortcoming is to some specific websites, when have recorded source IP address after certification is passed through, if other follow-up communication messages are come from other IP, can think it is reconnect or attack by mistake.
Summary of the invention
In order to overcome the deficiency of conventional load equilibrium, the invention provides and carry out suitable mathematical operation by source IP address and object IP address Was Used, forming a SESSION, when carrying out balancing link load routing, with this SESSION for uniquely to calculate standard.
Concrete technical scheme is: basic condition Was Used being defined as a session, add certain hash algorithm, for this session sets up a connection in internal memory, when there is not this in internal memory and connecting, carry out dynamic routing then to this SESSION, and by the internal memory entry of the result of routing with this SESSION of mark write, follow-up message navigates to this SESSION by HASH, then routing is got final product according to this mark, this kind of scheme has done a half-way house on traditional policybased routing and five elements load balancing, namely keep efficient, simultaneously also comparatively simple.
Accompanying drawing explanation
Nothing
Embodiment
Embodiment realizes this method, generally in bottom layer realization, to obtain higher efficiency by coding and hardware computation on outlet load-balancing device.
Claims (4)
1. using source/destination IP address as routing basic element during balancing link load, it is characterized in that: usually carry out HASH distribution by source IP address and object IP address binary, instead of traditional five elements, the method is applicable to ipv4/ipv6 network.
2. the method in right 1, it is characterized in that: HASH algorithm preserves the record of session in internal memory, when coordinating link Route Selection, identical source IP address and object IP address are identified as identical SESSION within the close time period, even if agreement, source port and destination interface are inconsistent.
3. the method in right 1, it is characterized in that, session has the time-to-live in internal memory, and pass through without movable message when exceeding this session of special time, then this session is by Automatic clearance.
4. the method in right 1, is characterized in that, when showing IP address linking number entry, only shows source IP, object IP or other subsidiary parameter, and not display protocol, source port and destination interface.
