For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The flow chart of the hardware table item installation method that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the present embodiment method comprises:
Step 101, mounted when having more the direction hardware table item when what have in the hardware list that come into force port and the port that comes into force that has more the direction hardware table item to be installed have a common factor, have more the direction hardware table item and come into force port and have more that the direction hardware table item has a common factor mounted to be installed have more that one of them splits at least in the direction hardware table item to be installed, make split have more the direction hardware table item at least on independent action each port in the common factor of the port that comes into force.
In specific implementation process, can according to actual needs hardware table item be installed in the hardware list of ASIC exchange chip usually, carry out various controls, for example flow control, access control etc. with message to the turnover port.For example: when hardware table item is used for message is conducted interviews when control, hardware table item can be Access Control List (ACL) (Access Control List; Abbreviate as: the rule ACL) etc.
For the ASIC exchange chip, it knows that a hardware table item acts on inbound port or acts on outbound port, and knows that also hardware table item acts on a port or acts on a plurality of ports.Wherein, inbound port is meant the port that receives message on the ASIC exchange chip, and promptly message enters the port of ASIC exchange chip; Outbound port is meant the port that E-Packets on the ASIC exchange chip, is about to the port of message output.In present embodiment and follow-up each embodiment, the hardware table item that acts on inbound port is referred to as the Inbound hardware table item, the hardware table item that acts on outbound port is referred to as the outgoing direction hardware table item.In addition, be divided into again according to the number of the outbound port of outgoing direction hardware table item effect and have more direction hardware table item and single outgoing direction hardware table item.Promptly in various embodiments of the present invention, have more the direction hardware table item and be meant the hardware table item that acts on a plurality of outbound ports simultaneously, just act on the hardware table item that a plurality of ports are controlled the message of outbound port direction simultaneously.
Usually, hardware table item mainly comprises matching field, several parts such as port and safety regulation come into force.Wherein, matching field is used for mating with some field of the message that passes in and out port, belongs to the message under that a kind of protocol type to judge message, just determines and need handle message with which type of hardware table item.Wherein, matching field can be the field such as source IP address, purpose IP address in the message.
The port that comes into force is meant the port that this hardware table item will affact.For the Inbound hardware table item, when mounted, the ASIC exchange chip generates the port bitmap automatically according to the port that comes into force of Inbound hardware table item, and the port bitmap is a kind of expression mode of representing port with bit.When the Inbound hardware table item acted on a port, the bit of this port correspondence was changed to 1, otherwise was 0.For the outgoing direction hardware table item, when mounted, the ASIC exchange chip can set out the port number field and the port numbers group field of direction hardware table item according to the port that comes into force of outgoing direction hardware table item, and port table can be set.When the outgoing direction hardware table item was single outgoing direction hardware table item, the ASIC exchange chip can be provided with port number field and come into force, and the port that will come into force is placed in this peer-port field.When the outgoing direction hardware table item when having more the direction hardware table item, the ASIC exchange chip can be formed a plurality of ports that come into force the form of port set (PORT_GROUP), for port set is distributed the port group number (GROUP_ID) that the overall situation is unique, port group number field is set simultaneously to come into force, and the port group number is placed in this port group number field, the corresponding relation of port and its affiliated port set of will coming into force stores in the port table, and port table promptly is set.Wherein, in port table, for each port that comes into force is set up a port group number field be used for representing the coming into force corresponding relation of port and its described port set.
Safety regulation is meant the specific strategy that message is handled, and for example message is carried out flow restriction, and message is filtered, message is transmitted or sent CPU or the like with message.
In the present embodiment, have more the direction hardware table item in the hardware list of ASIC exchange chip the time when installing one, the ASIC exchange chip is at first with the port that comes into force that has more the direction hardware table item to be installed, compares with the port that comes into force that has more the direction hardware table item in the hardware list; Judge whether having more of having installed in the hardware list exists come into force port and the port that comes into force that has more the direction hardware table item to be installed to have the mounted direction hardware table item that has more that occurs simultaneously in the direction hardware table item.If judged result is for existing, then the ASIC exchange chip has more the direction hardware table item and/or come into force port and the port that comes into force that has more the direction hardware table item to be installed exist the mounted direction hardware table item that has more that occurs simultaneously to split to be installed, make split have more the direction hardware table item at least on independent action each port in the common factor of the port that comes into force.Through after the deconsolidation process, each outbound port belongs to a port set at most, also acts on simultaneously and causes part to have more the problem that the direction hardware table item can't come into force on the same port on this port with regard to having solved a plurality of direction hardware table items that have more that act on a plurality of ports.If judged result is not for existing, then the ASIC exchange chip directly is installed to the direction hardware table item that has more to be installed in the hardware list.
Step 102, according to split result, the direction hardware table item that has more to be installed is installed in the hardware list.
When the ASIC exchange chip has more the direction hardware table item and/or come into force port and the port that comes into force that has more the direction hardware table item to be installed exist occur simultaneously mounted to have more after the direction hardware table item carries out deconsolidation process to be installed, the direction hardware table item that has more to be installed is installed in the hardware list according to split result.For example: when asic chip exists occur simultaneously mounted to have more the direction hardware table item when splitting to come into force port and the port that comes into force that has more the direction hardware table item to be installed, the ASIC exchange chip can directly be installed to the direction hardware table item that has more to be installed in the hardware list as a hardware table item.Again for example: when asic chip to the direction hardware table item that has more to be installed when splitting, need and to have more many outgoing direction hardware table items (except comprising single outgoing direction hardware table item, also may comprise having more the direction hardware table item in these outgoing direction hardware table items) that the direction hardware table item splits out and be installed in the hardware list by to be installed.
The hardware table item installation method of present embodiment, when installation has more the direction hardware table item, mounted when having more the direction hardware table item when what have in the hardware list that come into force port and the port that comes into force that has more the direction hardware table item to be installed have a common factor, by having more the direction hardware table item and mountedly have more the direction hardware table item one of them splits at least with the port that comes into force that has more the direction hardware table item to be installed has a common factor to be installed, make split have more the direction hardware table item at least on independent action each port in occuring simultaneously, thereby guarantee that each port can only belong to a port set at most, solve in the prior art many and had more the problem that the part hardware table item that causes when the direction hardware table item acts on same outbound port simultaneously can't come into force, made many hardware table items can to act on same port simultaneously.
The flow chart of the hardware table item installation method that Fig. 2 A provides for another embodiment of the present invention.Shown in Fig. 2 A, the method for present embodiment comprises:
Step 201, ASIC exchange chip compare the port that comes into force that has more the direction hardware table item in the come into force port and the hardware list that have more the direction hardware table item to be installed, judge whether having more in the hardware list exists come into force port and the port that comes into force that has more the direction hardware table item to be installed that the mounted direction hardware table item that has more of common factor is arranged in the direction hardware table item; If judged result is for being execution in step 202; If judged result is for denying execution in step 205.
Step 202, ASIC exchange chip obtain come into force in the hardware list port and the port that comes into force that has more the direction hardware table item to be installed has the mounted of common factor to have more the direction hardware table item, and execution in step 203.
Step 203, ASIC exchange chip are split as the direction hardware table item that has more to be installed the first outgoing direction hardware table item on independent action each port in occuring simultaneously and act on the second outgoing direction hardware table item on other ports each port in occuring simultaneously in the port that comes into force that has more the direction hardware table item to be installed simultaneously.
Wherein, the mounted common factor situation that has more the port that comes into force of direction hardware table item that has more the direction hardware table item and obtain from hardware list to be installed mainly contains three kinds of situations, respectively shown in Fig. 2 B-Fig. 2 D.For ease of statement, the mounted direction hardware table item that has more that will obtain from hardware list in describing below this step abbreviates the mounted direction hardware table item that has more as.
For first kind of situation shown in Fig. 2 B, there be n identical outbound port in to be installed having more in direction hardware table item and the mounted port that comes into force that has more the direction hardware table item, and the direction hardware table item that has more to be installed also comprises m1 other the port that comes into force, and the mounted direction hardware table item that has more also comprises m2 other the port that comes into force.Wherein n, m1 and m2 are respectively the integers more than or equal to 1.The ASIC exchange chip is split as independent action in the first outgoing direction hardware table item on n the port that comes into force with act on the second outgoing direction hardware table item on the individual port that comes into force of m1 simultaneously with the direction hardware table item that has more to be installed.Wherein, the first outgoing direction hardware table item has the n bar, and every first outgoing direction hardware table item is single outgoing direction hardware table item.That is to say that the ASIC exchange chip splits a direction hardware table item that has more to be installed for n bar list outgoing direction hardware table item and one second outgoing direction hardware table item.Wherein, when m1 was 1, the second outgoing direction hardware table item also was single outgoing direction hardware table item; When m1 greater than 1 the time, the second outgoing direction hardware table item is one and has more the direction hardware table item.
For second kind of situation shown in Fig. 2 C, there be n identical outbound port in to be installed having more in direction hardware table item and the mounted port that comes into force that has more the direction hardware table item, and the direction hardware table item of installing that has more also comprises m2 other the port that comes into force.Wherein n and m2 are respectively the integers more than or equal to 1.In this case, the port that comes into force that has more the direction hardware table item to be installed is the mounted subclass that has more the port that comes into force of direction hardware table item.The ASIC exchange chip is split as the first outgoing direction hardware table item of independent action on n the port that comes into force with the direction hardware table item that has more to be installed.Wherein, the first outgoing direction hardware table item has the n bar, and each first outgoing direction hardware table item is single outgoing direction hardware table item.That is to say that the ASIC exchange chip splits a direction hardware table item that has more to be installed for n bar list outgoing direction hardware table item.
For the third situation shown in Fig. 2 D, there be n identical outbound port in to be installed having more in direction hardware table item and the mounted port that comes into force that has more the direction hardware table item, and the direction hardware table item that has more to be installed also comprises m1 other the port that comes into force.Wherein n and m1 are respectively the integers more than or equal to 1.In this case, the mounted port that comes into force that has more the direction hardware table item is the subclass of the port that comes into force that has more the direction hardware table item to be installed.The ASIC exchange chip is split as independent action in the first outgoing direction hardware table item on n the port that comes into force with act on the second outgoing direction hardware table item on the individual port that comes into force of m1 simultaneously with the direction hardware table item that has more to be installed.Wherein, the first outgoing direction hardware table item has the n bar, and each first outgoing direction hardware table item is single outgoing direction hardware table item.That is to say that the ASIC exchange chip splits a direction hardware table item that has more to be installed for n bar list outgoing direction hardware table item and one second outgoing direction hardware table item.Wherein, when m1 was 1, the second outgoing direction hardware table item also was single outgoing direction hardware table item; When m1 greater than 1 the time, the second outgoing direction hardware table item is one and has more the direction hardware table item.
Step 204, ASIC exchange chip are respectively installed to the first outgoing direction hardware table item and the second outgoing direction hardware table item in the described hardware list, finish this fitting operation.
The ASIC exchange chip is installed to the n bar first outgoing direction hardware table item in the hardware list.Concrete, for every first outgoing direction hardware table item, the ASIC exchange chip directly is installed to the matching field and the safety regulation of the first outgoing direction hardware table item in the hardware list, and the port number field that this first outgoing direction hardware table item in the hardware list is set comes into force, the port that comes into force of the first outgoing direction hardware table item correspondence is arranged in the port number field, to finish the operation that the first outgoing direction hardware table item is installed.
When having the second outgoing direction hardware table item, the ASIC exchange chip is installed to the second outgoing direction hardware table item in the hardware list.When the second outgoing direction hardware table item was single outgoing direction hardware table item, its fitting operation was identical with the fitting operation of the first outgoing direction hardware table item, repeats no more.When the second outgoing direction hardware table item when having more the direction hardware table item, in the corresponding list item that the ASIC exchange chip directly is installed to hardware list with the matching field and the safety regulation of the second outgoing direction hardware table item, and with m1 the port generation port set that comes into force, the port group number of distributing overall uniqueness for port set, the port group number field that the second outgoing direction hardware table item is set comes into force, the port group number of distributing is arranged in the port group number field, corresponding relation with m1 come into force port and port set stores in the port table simultaneously, thereby finishes the fitting operation to the second outgoing direction hardware table item.
Step 205, ASIC exchange chip directly are installed to the direction hardware table item that has more to be installed in the hardware list, finish this fitting operation.
Mounted when having more the direction hardware table item when what do not have in the hardware list that come into force port and the port that comes into force that has more the direction hardware table item to be installed have a common factor, the ASIC exchange chip can directly be installed in the hardware list having more the direction hardware table item.Concrete, the ASIC exchange chip directly is installed to matching field that has more the direction hardware table item to be installed and safety regulation in the corresponding list item of hardware list, then n+m1 the port that comes into force generated port set, for port set is distributed the port group number, and the port group number field that the corresponding list item of hardware list is set comes into force, the port group number of distributing is arranged in the port group number field, the corresponding relation of port and the affiliated port set of will coming into force simultaneously stores in the port table, to finish the installation that has more the direction hardware table item to be installed.
Having more after the direction hardware table item is installed in the hardware list to be installed, when message need be transmitted, the ASIC exchange chip carries out the matched and searched of hardware list according to the field value of message, when inquiring the field value hardware table item identical with field value in the message, which is effective for the port number field of inquiry hardware table item and port group number field.When port number field is effective, the ASIC exchange chip is compared the port (being the port of outgoing message) that E-Packets with the port number field of hardware table item, if both unanimities, then this hardware table item comes into force on this port that E-Packets, after by the safety regulation in this hardware table item this message being handled, message is forwarded.When port group number field was effective, the ASIC exchange chip was inquired about port table according to port group number field, and the port that E-Packets is mated in the port table middle port group number field port identical with the port group number field of this hardware table item; If match the port consistent with the port that E-Packets, then this hardware table item comes into force on the port that E-Packets, and after by the safety regulation in this hardware table item this message being handled, message is forwarded.
Further specify, when message is when being forwarded with multicast or broadcast mode, message need forward from a plurality of ports, then in the present embodiment, the ASIC exchange chip need be compared each port and hardware table item middle-end port number fields, perhaps each port is mated in the port table middle port group number field port identical with the port group number field of hardware table item, determining whether hardware table item comes into force on all of the port that E-Packets, and after adopting safety regulation that message is handled on the port that comes into force of hardware table item message is forwarded.
The hardware table item installation method of present embodiment, when installation has more the direction hardware table item, mounted when having more the direction hardware table item when what have in the hardware list that come into force port and the port that comes into force that has more the direction hardware table item to be installed have a common factor, by the direction hardware table item that has more to be installed is split, the direction hardware table item that has more to be installed is split as single outgoing direction hardware table item on a plurality of independent actions each port in occuring simultaneously, thereby guarantee that each port can only belong to a port set at most, solve in the prior art many and had more the problem that the part hardware table item that causes when the direction hardware table item acts on same outbound port simultaneously can't come into force, made many hardware table items can to act on same port simultaneously.In addition, use has more the direction hardware table item when E-Packeting, after obtaining port group number field and coming into force, need further remove to search port table according to the port group number, its efficient that E-Packets is lower, and present embodiment is split as many single outgoing direction hardware table items by having more the direction hardware table item with one, can improve the efficient that E-Packets.
The flow chart of the hardware table item installation method that Fig. 3 provides for further embodiment of this invention.As shown in Figure 3, the method for present embodiment comprises:
Step 301, ASIC exchange chip compare the port that comes into force that has more the direction hardware table item in the come into force port and the hardware list that have more the direction hardware table item to be installed, judge whether having more in the hardware list exists come into force port and the port that comes into force that has more the direction hardware table item to be installed that the mounted direction hardware table item that has more of common factor is arranged in the direction hardware table item; If judged result is for being execution in step 302; If judged result is for denying execution in step 305.
Step 302, ASIC exchange chip obtain come into force in the hardware list port and the port that comes into force that has more the direction hardware table item to be installed has the mounted of common factor to have more the direction hardware table item, and execution in step 303.
The mounted direction hardware table item that has more that step 303, ASIC exchange chip will obtain from hardware list comes into force that port and the port that comes into force that has more the direction hardware table item to be installed have a common factor is split as the 3rd outgoing direction hardware table item on independent action each port in occuring simultaneously and acts on the 4th outgoing direction hardware table item on other ports each port that removes in the mounted port that comes into force that has more the direction hardware table item in the common factor simultaneously.
Wherein, the mounted common factor situation that has more the port that comes into force of direction hardware table item that has more the direction hardware table item and obtain from hardware list to be installed mainly contains three kinds of situations, respectively shown in Fig. 2 B-Fig. 2 D.For ease of statement, the mounted direction hardware table item that has more that will obtain from hardware list in describing below this step abbreviates the mounted direction hardware table item that has more as.
