Abstract
The invention discloses a multi-service access method based on DHCP protocol extension. With regard to a network access device and an application terminal, definition and extension are carried out on an Option 60 field based on a DHCP protocol; when the terminal operates a specific service and sends DHCP DISCOVER, a specific service tag is labeled on the Option 60 field in the DHCP DISCOVER and then the labeled Option 60 field is sent to the network access device; the network access device carries out parsing and determination on the filed as well as carries out forwarding to a specific service subnet according to the service tag; according to the above-mentioned processes, the application terminal can obtain an IP address that is distributed by the service subnet as well as service data are transmitted to a service application server terminal and are received by the IP address, so that a mechanism in which the application terminal accesses a plurality of service subnets can be realized. According to the formed mechanism, it can be ensured that application services carried by the plurality of service subnets can be utilized under circumstances that it is only necessary to establish one physical link between the application terminal and the network access device.
Description
Technical field
The present invention relates to Internet technical field, be meant a kind of multi-service access method especially based on the DHCP protocol extension.
Background technology
Along with the development of communication service, the development of particularly various communication service technology, communication user is more and more, how to become the problem of putting forth effort to consider in the current business development process for the user provides more better service and the efficient that improves service.
The network of various application terminal access communications operator uses all kinds of business; Different demands and specification requirement according to all kinds of business; In order to ensure professional stable, safe operation, operator is divided into each professional subnet with its network usually simultaneously, isolates unreachable between each professional subnet each other.
The terminal connects through wired or wireless, takes to dial or the mode access network of DHCP or static IP or the like; When using different application or business, need carry out network configuration and network switching, need user's interventional procedure usually using the terminal.
In view of this, the objective of the invention is to propose a kind of simple, be prone to row, be implemented under the situation of only setting up a physical connection between application terminal and the network access equipment, can insert a plurality of professional subnets simultaneously, use the method for the applied business that each subnet carries.
Summary of the invention
Saidly can find out from top; The mechanism that realizes visit multi-service subnet in application terminal based on the DHCP protocol extension provided by the invention; To network access equipment and application terminal, define and expand based on Option 60 fields of DHCP agreement, thereby realize that the application terminal visits the mechanism of a plurality of professional subnets; Only need set up under the situation of a physical connection applied business that can use a plurality of professional subnets to carry between application terminal and the network access equipment.
Have the following advantages specifically:
1) expand based on Option 60 Option Fields of DHCP agreement, compatible to existing protocol.
2) under the situation of only setting up a physical connection (wired or wireless) between application terminal and the network access equipment, can realize that a kind of application terminal visits the mechanism of a plurality of professional subnets.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the system principle sketch map.
Fig. 2 is the professional process description sketch map that uses.
Embodiment
With reference to the accompanying drawings the present invention is more comprehensively described, exemplary embodiment of the present invention wherein is described.
For realizing above-mentioned purpose, a kind of multi-service access method based on the DHCP protocol extension has been proposed.
Below in conjunction with the drawings, execution mode of the present invention is described.
The key point that realizes a kind of multi-service subnetwork access based on the DHCP protocol extension is following:
The client of Option60 is when initiating DHCP discover bag; Can add the Option60 option; DHCP relay equipment and DHCP server can be through this options of identification; Thereby know that client is any type of service, distribute suitable IP address and mandate accordingly, control user's accessed content and QOS.
When using certain subnet applied business to obtain the subnet services addresses on the application terminal; Fill in the Service Tag that represents business in the OPTION of DHCPDISCOVER 60 fields; Network access equipment is transmitted DHCP DISCOVER according to this Service Tag to the different business subnet; And transparent transmission is handled follow-up DHCP message; Network access equipment transmits the DHCP message to professional subnet according to DHCP OPTION 60 extension, is the professional subnet of ip address of terminal distribution by the Dynamic Host Configuration Protocol server of professional subnet.
Give one example below the workflow of system of the present invention is described, among this embodiment, business may further comprise the steps:
Step 1: application terminal and network access equipment have been set up wired or wireless physical connection, at first get access to private net address (192.168.1.x);
Step 2: when using certain subnet applied business to obtain the subnet services addresses on the application terminal; Fill in the Service Tag that represents business in the OPTION of DHCP DISCOVER 60 fields; Network access equipment is transmitted DHCP DISCOVER according to this Service Tag to the different business subnet, and transparent transmission is handled follow-up DHCP message;
Step 3: after the application terminal gets access to the dhcp address of professional subnet, use this address and operation system interactive service data;
Step 4: the application data for need not to the specified services subnet is transmitted then connects forwarding to acquiescence WAN by network access equipment after NAT handles.
Description of the invention provides for example with for the purpose of explaining, and is not the disclosed form that exhaustively perhaps limit the invention to.A lot of modifications and variation are obvious for those of ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present invention and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment that have various modifications that the present invention's design is suitable for special-purpose.
Claims (4)
1. the multi-service access method based on the DHCP protocol extension is characterized in that the application of a plurality of different sub-networks of carrying on a physical connection.
2. define based on Option 60 fields of DHCP agreement and expand, insert service label at OPTION60, label has comprised service attribute.
3. of claim 2, network access equipment is transmitted DHCPDISCOVER according to this Service Tag to the different business subnet, and transparent transmission is handled follow-up DHCP message.
4. multi-service subnetwork access method as claimed in claim 1 is characterized in that:
The client of Option60 can be added the Option60 option automatically and add Service Tag when being initiated DHCP discover bag.
Network access equipment is transmitted DHCP DISCOVER according to this Service Tag to the different business subnet, and transparent transmission is handled follow-up DHCP message.
Realize application terminal visit multi-service subnet through the DHCP protocol extension; Only need set up under the situation of a physical connection between application terminal and the network access equipment; The applied business that can use a plurality of professional subnets to carry, the different service that belongs to different sub-network convenient for users.
