Description
Technical field
The present invention is a kind of Network Access Method and device about field of network communication specifically.
Background technology
In the prior art; At existing network terminal product; In products such as PC, various host, mobile phone, when facing the situation that multiple network uses simultaneously, as: maybe be in visit Internet internet through VPN VPN visit intranet intranet.The IP stack at existing terminal is divided into two kinds, and a kind of is the IPv4 protocol stack, and another kind is the protocol stack of IPv4 and IPv6, and corresponding is the routing table of an IPv4 routing table or an IPv4 and an IPv6.The method of supporting many networks in the prior art simultaneously is to form different list item in the routing table through address planning, and the packet of upper layer application sends to according to different list items that various network realizes.
In realizing process of the present invention, the inventor finds to have following problem in the prior art at least: when landing a plurality of network simultaneously, the IP address of each network needs to coordinate each other; And could communicate by letter according to network segment configuration route, but when reality was used, these IP addresses can't be coordinated each other; And each network configuration all is default route; These routes are conflicted each other, cause supporting multiple network simultaneously, promptly when using a kind of application, can't use other a kind of application simultaneously.
Summary of the invention
The embodiment of the invention provides a kind of Network Access Method and device, can solve the problem that can't land a plurality of networks in the prior art simultaneously.
To achieve these goals, the embodiment of the invention provides a kind of Network Access Method, and this method comprises: receive the request of a plurality of application process visit heterogeneous networks; From each self-corresponding routing table of described application process, search described request link corresponding and send data to this link.
To achieve these goals, the embodiment of the invention also provides a kind of network access device, and this device comprises: the request receiving element receives the request of a plurality of application process visit heterogeneous networks; Link is searched the unit, is used for searching described request link corresponding and sending data to this link from each self-corresponding routing table of described application process.
The beneficial effect of technique scheme is, a kind of Network Access Method and device are provided, and makes application program can visit a plurality of networks simultaneously, and is user-friendly.

Embodiment
For making the object of the invention, technical scheme and advantage clearer,, the present invention is explained further details below in conjunction with execution mode and accompanying drawing.At this, exemplary embodiment of the present invention and explanation thereof are used to explain the present invention, but not as to qualification of the present invention.
Embodiment one
In the present embodiment, a plurality of processes that are used for visiting respectively a plurality of networks are bound an IP stack separately, the corresponding routing table of each protocol stack.As two application processes and two IP stacks have been shown among Fig. 1, for example the IPv4 protocol stack of an internet network and an intranet network IPv4 protocol stack; Or the IPv6 protocol stack of an internet network and an intranet network IPv6 protocol stack; Also can be IPv4 protocol stack and the IPv6 protocol stack of an internet network, intranet network IPv4 protocol stack and IPv6 protocol stack.Each corresponding routing table of each IP stack, described two IP stacks can be identical IP agreements, also can be different IP agreements.Wherein, application process bundlees with IP stack, after application layer IP data arrive the IP layer through transport layer; Bind the definite corresponding routing table of the network information at place according to process and carry out route querying; For example application process is a visit internet network, and the routing table in the IPv4 protocol stack that then definite corresponding routing table is the internet network finds a route in this network through routing table then; According to finding corresponding link, carry out data and send.
After adopting the scheme in the above embodiment of the present invention; Can make the user use multiple network (for example Internet and Intranet) simultaneously and do not produce conflict; Because the present invention has corresponding independent IPv4 protocol stack routing table or IPv6 protocol stack routing table to each network; Each routing table can have the default route of oneself, and the process of each application program can correspond to different IP stacks, visits various network respectively.
Embodiment two
In the present embodiment, a plurality of processes that are used for visiting respectively a plurality of networks are bound a routing table separately, the corresponding a plurality of routing tables of IP stack.Bind a routing table separately as two application processes have been shown among Fig. 2, two corresponding same IP stacks of routing table for example comprise internet network routing table and intranet network routing table in an IPv4 protocol stack; Or comprise internet network routing table and intranet network routing table in an IPv6 protocol stack.The application process of visit internet network is bound the application process of internet network routing table, visit intranet network and is bound the intranet network routing table; After application layer IP data arrive the IP layer through transport layer; Routing table according to process is bound is carried out route querying; Thereby find a route, to corresponding link, carry out data and send according to route querying.
After adopting the scheme in the above embodiment of the present invention; Can make the user use multiple network (for example Internet and Intranet) simultaneously and do not produce conflict; Because the present invention has corresponding independent IPv4 protocol stack routing table or IPv6 protocol stack routing table to each network; Each routing table can have the default route of oneself, and the process of each application program can correspond to different routing tables, visits various network respectively.
