Abstract
The method includes steps: client end protocol, server end protocol and message format protocol; thus, in optical transmission device. Network management can obtain IP address of Ethernet port of gateway and cells of network. The method is suitable to optical transmission device managed through Ethernet port and based on TCP/IP protocol stack.
Description
Technical field:
The present invention relates to field of network communication, especially the discovery protocol method of IP address.
Background technology:
When webmaster need pass through the NEIP managing network, must guarantee that at first the communication of webmaster and Gateway Network Element is normal.Connect by Ethernet interface between general webmaster and the Gateway Network Element, their Ethernet interface IP address of ICP/IP protocol stack requirement must be at the same network segment, so webmaster is when the configuration communication setting, need a kind of privately owned agreement to find the Ethernet interface IP address of Gateway Network Element, no matter whether they are at the same network segment.
The objective of the invention is to: the implementation method that a kind of Gateway Network Element Ethernet interface IP address discovery protocol is provided.
Summary of the invention:
It comprises: client protocol; Server-side protocol and message format agreement;
A, client protocol:
Trigger when being subjected to certain, this end is 5333 request package to multicast group 224.0.0.33 transmission udp port; The arrival of wait acknowledge bag then; If on udp port 5333, receive packet, just resolve the content in this bag; If response packet just obtains the Ethernet interface IP address/netmask of the webmaster network element in the bag and the NEIP of correspondence, and show by certain mode; If not, then do not process, abandon quietly;
B, server-side protocol:
On udp port 5333, wait for the arrival of request package,, just resolve the content in this bag if receive packet; If request package, just to multicast group 224.0.0.33 send udp port be in 5333 the bag information comprise protocol package type, webmaster network element Ethernet interface IP address/netmask and for the response packet of NEIP; If not request package, then do not process, abandon quietly;
C, message format agreement:
Be 32 bytes; Its content comprises: TYPE: protocol type; NEIP: the NEIP of Gateway Network Element; ETHIP: the Ethernet interface IP address of Gateway Network Element; ETHIP: the Ethernet interface IP address of Gateway Network Element.
Description of drawings:
Accompanying drawing is 1 server end of the present invention and client-requested-response relation figure;
Accompanying drawing is the 32 bit bytes definition distribution diagram of 2 message formats of the present invention.
Execution mode:
Client (webmaster):
Trigger when being subjected to certain, it is 5333 request package that this end sends udp port to multicast group 224.0.0.33, and the content of request package includes only the protocol package type, is request type, then the arrival of wait acknowledge bag.If on udp port 5333, receive packet, just resolve the content in this bag: at first judge whether to be response packet, if just obtain the Ethernet interface IP address/netmask of the webmaster network element in the bag and the NEIP of correspondence, and show by certain mode; If not, just do not process, abandon quietly.
Server end (Gateway Network Element):
On udp port 5333, wait for the arrival of request package, if receive packet, just resolve the content in this bag: at first judge whether to be request package, if, just sending udp port to multicast group 224.0.0.33 is 5333 response packet, in the bag information comprise protocol package type, webmaster network element Ethernet interface IP address/netmask and for NEIP; If not request package, do not process, abandon quietly.
Message format:
Word length is 32 bytes, and wherein the 0-7 position is TYPE; The 8-15 position is NEIP; The 16-23 position is ETHIP; The 24-31 position is ETHIPMASK.
TYPE: protocol type is an integer number, the network preface, and optional value replys-1 for request-0;
NEIP: the NEIP of Gateway Network Element is an integer number, the network preface, and when protocol type was request, its value should be 0;
ETHIP: the Ethernet interface IP address of Gateway Network Element is an integer number, the network preface, and when protocol type was request, its value should be 0;
ETHIPMASK: the Ethernet interface netmask of Gateway Network Element is an integer number, the network preface, and when protocol type was request, its value should be 0.
This agreement is a kind of application level protocol, is used for the Ethernet interface IP address that webmaster is found Gateway Network Element, also is a kind of REQUEST/RESPONSE agreement simultaneously.A client (for example webmaster) sends the set form request package to server (Gateway Network Element) end, server receives request package, self Ethernet interface IP address/netmask and corresponding NEIP are encapsulated in the respond packet, send to client then, client is resolved this bag after receiving response packet, thereby obtain the Ethernet interface IP address/netmask and the corresponding NEIP of Gateway Network Element, shown in figure one.Server end need be integrated in the host software, and client can be integrated in the webmastering software, also can independently be a little application (small tool).
Consider that the Ethernet interface IP address that links to each other between Gateway Network Element and the webmaster may be at the same network segment, can't carry out communication by clean culture, so the mode of agreement employing multicast is guaranteed communication and under any circumstance can both be carried out, and no matter their Ethernet interface IP address whether at the same network segment, server end and client all add the multicast group of 224.0.0.33.Simultaneously, in order to receive and dispatch multicast message, agreement is based on insecure udp protocol, and the udp port that server end and client are all used number is 5333.Owing to be based on insecure udp protocol, agreement does not adopt any reliable mechanism to guarantee the correct transmission and the reception of the bag of asking/replying yet simultaneously, so this agreement equally also is an insecure agreement.
This agreement is a stateless agreement, and it does not need any end of communication to safeguard that any state guarantees synchronously.
