The present invention is described in more detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention,
It is not intended to limit the present invention.
The invention discloses the message transmitting method based on HTTP relaying techniques in a kind of EOC networks, specifically include with
Under step：It is relayed as HTTP Step 1: selecting a proxy management server in EOC networks, the proxy management clothes
Business device is used to manage all devices on its periphery, is built by double layer network between the proxy management server and managed devices
Vertical connection.Step 2: assume that user 1 manages the device A 1 that Vlan ID are VlanA, then user 1 first with proxy management server
Connection is established, proxy management server receives the HTTP request message of user 1, therefrom parses the MAC of managed devices A1
Address MacA1.Step 3: MAC Address Query Information table of the proxy management server according to managed devices A1, information table is as schemed
Shown in 5, the information such as IP, VLAN of managed devices are obtained；If searching failure, Dynamic Host Configuration Protocol server of the proxy server from itself
An IP is distributed in IP address pond（Such as IpA1）Managed devices A1 is given, meanwhile, proxy management server uses LLDP agreements
The vlan information for obtaining managed devices A1 is VlanA, establishes a new information table, MAC, IP of recording equipment A1,
The information such as VALN, and user's access times of setting information table, line duration.When subsequently accessing again, directly basis is managed
The MAC Address of device A 1 obtains corresponding IP and vlan information in record sheet；When facility information list item fails（For example list item is old
Change time-out）When, then release device A1 distribution IpA1.Step 4: proxy management server by newly assigned IpA1 be handed down to by
Management equipment A1, and VlanA identical with managed devices A1 is configured, establish a message Transfer pipe.In this way in EOC networks
In, HTTP relaying techniques are based on, the connection of user 1 and managed devices A1 is just established, realizes the mutual of HTTP message
Forwarding.
Fig. 3 is the realization principle of the HTTP relayings of the present invention.In HTTP relaying techniques and existing HTTP in the present invention
It is after identical：It is required for passing through TCP into http session layer by three-layer network network layers, four layers of transportation level：8080 ports with
Managed devices establish connection；Difference is：HTTP relaying techniques in the present invention establish connection with managed devices also to be needed
To pass through double layer network, the HTTP relayings of invention are to be set according to layer two MAC, vlan information automatic IP address allocation to being managed
It is standby, pass through TCP：80 ports, IP and Vlan and managed devices, which are established, to be connected, and realizes the mutual forwarding of HTTP message.
Web client is to proxy management server（HTTP is relayed）Managed devices are contained in the HTTP request of transmission
MAC information, proxy management server are distributed from the Dynamic Host Configuration Protocol server address pool of itself under an IP address according to MAC Address
Managed device is issued, meanwhile, proxy management server can obtain the Vlan information of managed device, establish an information table, information
Table uses timing aging mechanism, often once accesses, and refreshes corresponding information table ageing time, and ageing time time-out then discharges
The IP of equipment.
Usual administrator needs to carry out authentication, if there is multiple devices need to manage, then managing in access equipment
Reason person should accurately remember the authentication mode of every equipment, again every equipment of frequent certification, give the management band of administrator
Carry out certain burden.
In order to mitigate the administrative burden of administrator, HTTP of the invention relaying uses automatic authority distribution.Automatic permission point
With referring to the Permission Levels of automatic setting management by certain specific properties (such as management domain described below, period etc.)
(generally can divide Permission Levels by different accounts), without the mode of administrator's intervention, administrator is not necessarily to certification, Ke Yizhi
Management equipment is connect, if administrator needs, with the identity authority management equipment of higher level, to need manual authentication.The present invention
The access rights of HTTP relay management persons are distributed by administrator's identity, and administrator's identity can carry out on agent equipment
Configuration, can also be by information such as the topology locations, management domain, time of managed devices come the person's of allocation managing permission.
What is established between HTTP relayings and managed device is the short connections of HTTP, therefore, all sessions is all placed on one
The mode handled in process is difficult to realize.Under normal circumstances, the time of a page request is very short, each session
With in HTTP relaying processes completion handle, until conversation end；But there is also the request time of some pages is longer,
HTTP relays the current session of process long time treatment, causes other sessions can not timely processing.
In view of the presence of the above problem, HTTP relaying techniques of the invention handle session by the way of multi-process.
It handles in conversation procedure, sets the time-out time of session, another subprocess is created if time-out, after the completion of subprocess
Continuous processing, HTTP relay process（Host process is for the time being）It exits, goes to handle other new sessions.This makes it possible to by processing time
Longer session, which is cut into subprocess, to be handled, and host process can handle multiple new sessions simultaneously.
The coefficient and parameter gone out given in the above embodiments is available to those skilled in the art to realize or use
Invention, invention, which does not limit, only takes aforementioned disclosed numerical value, in the case where not departing from the thought of invention, the technology of this field
Personnel can make above-described embodiment various modifications or adjustment, thus the protection domain invented is not by above-described embodiment institute
Limit, and should be the maximum magnitude for meeting the inventive features that claims are mentioned.
