When business disk startup initializes, packet filtering module creates caching and message queue first, and completes protocol module note
Volume, specifically includes following steps：
S110. when business disk startup initializes, caching and message queue are created, the caching is for storing what main control unit issued
Protocol massages, each type of message correspond to a message queue.
S120. when configuration module and each service protocol Module registers are to packet filtering module, packet filtering module will match
Module and each service protocol module one message queue of each auto correlation are set, and is configured in allocation list is filtered in the reception of establishment
It is associated with list item, association list item includes type of message, forwarding switch, VLAN ACTION switches and VLAN ACTION operations, is received
It is as shown in table 1 to filter allocation list：
Table 1：Receive filtering allocation list
Forwarding switch includes the enabled of forwarding capability or goes to enable.
VLAN ACTION switches, which include that VLAN is pretreated, to be enabled or goes to enable.
VLAN ACTION operations include VLAN strippings or VLAN transparent transmissions.
The present embodiment is illustrated by taking configuration message and multicast protocol message as an example, wherein the VLAN of configuration message
ACTION switches are enabled, and the VLAN ACTION switches of multicast protocol message is go to enable, and shown in Figure 2, service board is to master
The processing method of the protocol massages issued of manipulating stock quotations includes the following steps：
S210. transceiver module receives the protocol massages that main control unit issues, and is transmitted to packet filtering module.
S220. packet filtering module obtains type of message after carrying out Preliminary Analysis to protocol massages, specifically, to protocol massages
Ethernet type judged, if the TAG value of the configuration message type of master-slave communication, be then judged as configuration message；To association
Second bit (bit) for discussing the target MAC (Media Access Control) address of message is judged, if second bit is 1, is judged as multicast
Protocol massages.
S230. according to type of message, the corresponding table item for receiving filtering allocation list is searched.
S240. judge whether corresponding forwarding switch goes to enable, if so, entering step S250；If it is not, entering step
S260。
S250. protocol massages are abandoned, are terminated.
Packet filtering module is after transceiver module gets protocol massages, according to the message class received in filtering allocation list
Type notifies corresponding configuration module or service protocol module protocol massages to be treated, if receiving filtering allocation list to this
The protocol massages of type are configured to inhibit (that is, not forwarding), then do not transmit the protocol massages, avoid the CPU of waste service board
Resource.
S260. according to type of message, judge whether corresponding VLAN ACTION switches enable, if so, entering step
S270；If it is not, entering step S280.
S270. judge whether VLAN ACTION operations are VLAN strippings, if so, entering step S290；If it is not, entering step
Rapid S280.
S280. multicast protocol message is made no modifications, is put into caching, enters step S291.
S290. the VLAN of configuration message is removed, modified configuration message is put into caching.
Pretreatment to protocol massages includes determining whether to make VLAN according to its type of message and VLAN ACTION switches
Processing shells the VLAN of the protocol massages specifically, when the VLAN ACTION switches of protocol massages are pretreated enabled
It is cached from rear deposit；When the VLAN ACTION switches of protocol massages go enabled for pretreatment, protocol massages are directly stored in slow
It deposits.
S291. packet filtering module packet storage information is stored in after corresponding message queue notify associated configuration module or
Person's service protocol module.Packet storage information includes the packet length and protocol massages place cache location of the protocol massages.
S292. configuration module and service protocol module extract packet storage information from associated message queue, and according to
Packet storage information obtains pretreated protocol massages from caching and carries out subsequent protocol processing.
Service board is extracted the packet storage information in each message queue according to the processing priority of setting and is handled,
Under normal conditions, the processing priority of configuration message is higher than issuing service protocol massages, therefore, service board priority processing configuration report
The corresponding message queue of text, it can be ensured that configuration message obtains timely processing, improve service board and main control unit communication efficiency and
Reliability.Multicast protocol message, line identification protocol massages, RSTP protocol massages and ospf protocol message processing priority not
With or it is identical.
In addition, service board can also forward each issuing service protocol massages of threshold value extraction corresponding according to the message of setting
Packet storage information in message queue is simultaneously handled.
Specifically, configuration module carries out subsequent protocol processing to pretreated configuration message, multicast protocol module is to pre-
Treated, and multicast protocol message carries out subsequent protocol processing.Protocol massages need not move through each configuration module and service protocol
Module, effectively reduces the processing links of protocol massages, and being isolated can between configuration module and each service protocol module
What can be generated influences each other, and improves the reliability of Message processing.
For the same protocol massages, step S291 and S292 are successively executed, for different protocol massages, step S291
Can be successively to execute, or be performed simultaneously with S292.
Service board is extracted the packet storage information in each message queue and is handled simultaneously or successively.Specifically,
In step S292, each service protocol module can extract the packet storage information in associated message queue and be located simultaneously
Reason can also make each service protocol module extraction is associated to disappear by poll or according to the processing priority mode of setting
It ceases the packet storage information in queue and is handled.When service board simultaneously to the packet storage information in each message queue into
When row processing, the Message processing efficiency of service board and the communication efficiency of network are improved.
When receiving protocol massages, packet filtering module uniformly carries out VLAN strippings or the operation of transparent transmission, reduces configuration message
Amount of storage, save cache resources；Configuration module and each service protocol module only need processing protocol task, need not be to agreement
The VLAN processing that message is decapsulated further improves the Message processing efficiency of configuration module and each service protocol module.
