Background technology
Along with the fast development of Network and progressively refinement, traditional network equipment becomes no longer handy when handling these business.Such as, require equipment can do data forwarding and not only can insert voice, require equipment can finish load balancing but also can carry out content safety and filter.At this moment, a family independently technology producer be difficult to offer simultaneously desired all services of user.For this reason, the user need buy the equipment of a plurality of producers usually, and those equipment are linked together.So not only interoperability often goes wrong, equipment room cooperates and to be not easy especially to consult, and the equipment of giving administer and maintain the burden of bringing on the cost.
With switching equipment (described switching equipment comprises switch and router) is example, and at present according to position in the network and effect, switching equipment is divided into low and middle-end switching equipment and core switching device usually.The major function of low and middle-end switching equipment is to compile and carry out service management, and the major function of core switching device is quick forwarding, makes packet pass through IP backbone as far as possible apace.The low and middle-end switching equipment generally is in the marginal position of network.The low and middle-end switching equipment, can rely on inner Ethernet data message to transmit as simple professional Ethernet switch and realize function of exchange with ASIC (application-specific integrated circuit (ASIC)), but, in the face of the traffic performance requirement that becomes increasingly abundant, as IPSec (IP Security agreement), IPS (IntrusionProtect System intrusion prevention system), voice and wireless etc., simple professional Ethernet switch can not satisfy those professional demands.
For this reason, consider whether the business components of finishing the miscellaneous service function to be integrated into and form an integrated equipment on the basic components, thereby reduce the appearance of inter-communicating problem and reduce the maintenance and management cost, and then provide more high quality-of-service for the user.Still be example with simple professional Ethernet switch, the business components such as intelligent interface board that carry processor (CPU) can be integrated in the simple professional Ethernet switch, allow the software or the hardware of business components to provide by each producer, like this, on simple professional Ethernet switch, can finish the miscellaneous service function, thereby the equipment that makes satisfies various abundant business demands.
The applicant has proposed a kind of OAA framework, the equipment of different vendor is integrated into the system of a loose coupling.A system that meets the OAA framework comprises NFC and the IAC (seeing also Fig. 1) that connects by ILC (Interface LinkageComponent, interface link).NFC is the above-mentioned basic components of mentioning, IAC is the above-mentioned business components of mentioning.Wherein NFC is the main body of OAA system, is responsible for carrying out message and transmits, and the function of complete router and switch is arranged, and also is the core of user management control; IAC is the business service main body that is used to provide the additional function of various application, generally shows as a veneer or button card in the OAA system; ILC need transmit and the path of control information transmission for NFC and IAC provide message, yet, do not have existing ILC at present and realize communication between NFC and the IAC.
With simple professional Ethernet switch is example, sees also Fig. 2, and it is the structured flowchart of a simple professional Ethernet switch.Be provided with a plurality of distributed Ethernet data messages forwarding ASIC in the inner integrated Ethernet data message forwarding of simple professional Ethernet switch with ASIC (special integrated chip) or switch inside.ASIC realizes the reception, identification, forwarding lookup of Ethernet message and to functions such as outbound port transmissions.Host CPU (processor) is realized the management maintenance of system and to the functions such as control of ASIC in this equipment.Various port is used to receive and dispatch message, is integrated with physical layer block in port usually.Physical layer block (PHY 0-PHY n) is used to provide the physical layer link of a plurality of ethernet ports to connect, and the flow that is implemented in the network inserts and converges.The logic diagram of above-mentioned simple professional Ethernet switch in fact also is a part of distributed Ethernet switch structure.Be connected to each other together by a plurality of such functional modules among the last figure, just formed more jumbo distributed Ethernet switch.
It is reception processing and the forwarding that core is carried out the Ethernet data message that present simple professional Ethernet switch all is based on ASIC.And in fact Internet development is very fast, has a lot of novel applied business to need to handle, as intrusion detection and protection, prevent malicious attack, fire compartment wall, anti-virus, network flow monitoring and applied business processing etc.ASIC after owing to dispatch from the factory has solidified some function in advance, the difficulty of carrying out reprogramming on this basis is very big, therefore the demand of these Business Processing tells irrealizablely for the ASIC of simple professional Ethernet switch, promptly allows to realize also to be to be subjected to bigger restriction on function and performance in other words.And industry has had a lot of producers to may be provided in ripe applied business process software, but handle special-purpose ASIC and realize that these softwares based on autonomous system are difficult on the simple professional Ethernet switch integrated because simple professional Ethernet switch is based on the hardware structure of particular design and Ethernet.It is a problem that presses for solution at present that intelligent interface board how to realize having the independent processor system is connected on the simple professional Ethernet switch.
That is to say how to make to communicate between NFC and IAC two parts, and then make IAC to be integrated into to become possibility on the NFC, thereby can provide high quality services, become the present problem that solves of needing for the user.

Embodiment
Below in conjunction with accompanying drawing, specify the present invention.
Figure 1 shows that a kind of typical structure of the OAA system that the present invention uses.The ILC that connects NFC and IAC among the OAA generally includes control interface and datum plane interface, control interface can be the interface that asynchronous serial port, synchronous serial interface etc. are supported stream mode, also may be an independent Ethernet physical port, perhaps shared physical port with datum plane.Control interface on the NFC is connected with control interface on the IAC, is used to carry out the communication of control information, and the datum plane interface on the NFC is connected with datum plane interface on the IAC, is used to carry out the communication of data message.In addition, can comprise a plurality of IAC that finish difference in functionality in an OAA system.
In the OAA system, the function of forwarding is finished by NFC, and professional additional treatments is finished by IAC.At different application, the applicant defines 4 kinds of mode of operations, can finish communicating by letter between NFC and the IAC by one of these 4 kinds of patterns or wherein several combinations.
1, main frame (Host) pattern
IAC resembles a main frame on the network, has the IP address of oneself, exists as the network tip.The IP message all is that the Ethernet interface of logical ILC is transmitted.This mode, NFC only finishes simple message and transmits, and IAC then as the promoter and the recipient of data message, receives and dispatches various messages, and NFC is exactly the gateway of IAC.
2, mirror image (Mirror) pattern
NFC as requested, duplicates a IAC of giving to specific message in the process that message is transmitted, original message continues to finish normal forwarding.Analyze later on and handle and IAC receives this message, then with packet loss.Under this pattern, mirror image message also is to transmit by the ILC Ethernet interface.
3, be redirected (Redirection) pattern
Under this pattern, NFC as requested, gives IAC specific message redirecting in the message repeating process.After IAC handles, or abandon, or pass through.If pass through, then message is by the intact NFC that returns, and NFC then continues to continue to handle from the place of interrupting originally, finishes follow-up forwarding work.Under this pattern, the message that is redirected also is to transmit by the Ethernet interface of ILC.
4, penetrate (Pass-Through) pattern
Under this pattern, IAC does not have configuration of IP address, and external Ethernet interface must be arranged, and data flow into from this interface, pass IAC, and the Ethernet interface of process ILC is to NFC, perhaps in the other direction.As if at NFC, external data similarly is the Ethernet interface that has directly arrived ILC, and IAC does not exist the same.
In order to realize above-mentioned disclosed four kinds of patterns, need NFC can finish communicating by letter between data and the control information with IAC.Below how to realize comprising communicating by letter of data and control information between NFC and the IAC with regard to explanation earlier.
See also Fig. 3, it realizes the structural representation of the system that communicates by letter between first parts and second parts for the present invention is a kind of.Described first parts are forwarded parts NFC, and described second parts are separate traffic parts IAC, and described system is ILC, and ILC comprises:
Data channel: be used to set up and transmit the data message that comprises message source address and/or destination address information between NFC and the IAC;
Management channels: be used for communicating control information between NFC and IAC;
Status protocol passage: be used between NFC and IAC, carrying out the mutual of status protocol.
Data channel can adopt ethernet port to realize.By this data channel Data transmission between NFC and IAC.Simultaneously, for source or the destination that can know message,, need to carry source address and/or destination address in the Ethernet data message of data channel transmission so that carry out message control.IAC can handle described message according to the source address and/or the destination address of the message that receives.Whether it is illegal message according to the source address of message and/or destination address message to be carried out analysis and judgement such as, IAC, if, dropping packets then, otherwise return message is intact.
Data channel comprises first ethernet port and second ethernet port, described first ethernet port is transmitted first ethernet controller of using ASIC for connecting NFC Ethernet data message, perhaps transmit first ethernet controller and first physical layer block that is connected first ethernet controller of using ASIC for connecting NFC Ethernet data message, described second ethernet port is for connecting the IAC processor or being integrated in second ethernet controller on the IAC processor, perhaps for connecting the IAC processor or being integrated in second ethernet controller and second physical layer block that is connected described second ethernet controller on the IAC processor.Core component on the ethernet switching device is an ethernet switch hub spare, and the essence of this device is one or more ethernet ports.Each ethernet port comprises an ethernet controller that is integrated with physical layer block, or comprise ethernet controller and the physical layer block that is not integrated with physical layer block, physical layer block can adopt existing physical layer block chip, the BCM5461S of Broadcom company, BCM5464SR, the 88E1145 device of Marvell company etc.
That is, IAC and NFC interconnect by ethernet port, and optimum mode is one or more 10GE Ethernets that bundle, and certainly, also can be that one or more bundles 10M, 100M, the 1000M Ethernet also can be used for this interconnection.
The status protocol passage is mainly used in communicating control information between NFC and IAC.Particularly, when between NFC and the IAC after the Ethernet interface link is normal transmitting control information.If utilize the control information of status protocol channel transfer, described control information is to utilize the Ethernet protocol make an appointment to carry out mutual between NFC and the IAC.In addition, the present invention can be provided with management channels and transmit simple control and management information.And the status protocol passage can transmit some senior state of a control information, and promptly status protocol passage and management channels transmit dissimilar control informations.By this status protocol passage, transmit between NFC and the IAC that heartbeat detection, clock synchronization, veneer are restarted, state information etc.Those control informations can be that NFC and IAC make an appointment, such as, the Ethernet message format of control information by making an appointment.
NFC normally is in normal condition at IAC and issues the literary composition of delivering newspaper.Whether be in normal condition in order to detect IAC, NFC of the present invention need carry out the IAC heartbeat detection.NFC carries out heartbeat detection to IAC multiple implementation.Such as, NFC and IAC make an appointment and are used to show that IAC the message format of unusual heartbeat message do not occur and sends the interval, and this heartbeat message is the control message that NFC and IAC make an appointment.Heartbeat message can only carry the sign of a heartbeat message.IAC regularly sends heartbeat message by the status protocol passage, when NFC receives this heartbeat message by the status protocol passage in the predefined time, illustrates that this IAC does not occur unusually.Suppose that IAC served as to send at interval to send heartbeat message to NFC with 5 seconds, then NFC does not receive the heartbeat message that any IAC sends in the predefined time cycle (as 15 seconds), illustrate that this IAC has occurred unusually, can handle this IAC according to predefined indication and occur unusually, as send warning etc.
NFC and IAC also needed to guarantee the clock synchronization of NFC and IAC before data interaction.In order to reach the clock synchronization of NFC and IAC, NFC and IAC carry out clock synchronization by the status protocol passage.Such as, NFC sends the clock synchronization message of making an appointment to IAC by the status protocol passage, and IAC receives the clock synchronization message that NFC issues, and carries the current time of NFC end in the described clock synchronization message; IAC is according to synchronous local terminal clock of the current time in the described clock synchronization message.
After IAC is being restarted, restart message notifying NFC by what make an appointment, so that obtain some system's initial values, reconfigure the setting on the IAC from NFC.And NFC and IAC are known the present residing state information in opposite end by the status protocol passage.
Described status protocol passage comprises three-ethernet port and the 4th ethernet port, perhaps multiplexing first ethernet port and second ethernet port carry out the mutual of status protocol, described three-ethernet port is for connecting the three-ethernet controller of NFC host-processor, perhaps for connecting the three-ethernet controller and the 3rd physical layer block that is connected described three-ethernet controller of NFC host-processor, described the 4th ethernet port is for connecting the IAC processor or being integrated in the 4th ethernet controller on the IAC processor, perhaps for connecting the IAC processor or being integrated in the 4th ethernet controller and the 4th physical layer block that is connected described the 4th ethernet controller on the IAC processor.
For transmitting control information before the Ethernet interface link is normal, comprise that configuration carries out the information of ethernet communication (as the IP address of last second ethernet controller of configuration IAC or dispose second ethernet controller of IAC and the IP address of the 4th ethernet controller) on the IAC, the present invention also is provided with a management channels.Except the Ethernet interface link utilizes this management channels transmitting control information before normal, can also utilize the management channels transmitting control information in other situation (such as, some simple control commands).This management channels can be a serial port channel, also can be the ethernet port passage that can simulate serial port, the Ethernet interface that this Ethernet interface that can simulate serial line interface can only be operated in interconnection be under the situation of internal default IP address.But the present invention adopts the serial port passage to realize management channels usually.
Particularly, described management channels comprises first universal asynchronous reception/transmitter and second universal asynchronous reception/transmitter, wherein:
First universal asynchronous reception/transmitter connects host-processor or directly is integrated on the host-processor, is used for the conversion of the parallel control data and the Serial Control data of host-processor;
Second universal asynchronous reception/transmitter, connect first universal asynchronous reception/transmitter, connect the processor of IAC or be integrated on the processor of IAC, be used for conversion with parallel control data on the processor and Serial Control data, and Serial Control data communication between foundation and the first universal asynchronous reception/transmitter.
First universal asynchronous reception/transmitter is directly connected to the local bus Local Bus of host-processor, perhaps first universal asynchronous reception/transmitter is connected to by a converting unit on the PCI/PCI-X/PCI Express bus of host-processor, and described converting unit is used for the conversion between PCI/PCI-X/PCI Express bus data and the local bus Local Bus data.
Second universal asynchronous reception/transmitter is directly connected to the local bus Local Bus of IAC processor, perhaps second universal asynchronous reception/transmitter is connected to by a converting unit on the PCI/PCI-X/PCI Express bus of processor, and described converting unit is used for the conversion between PCI/PCI-X/PCI Express bus data and the local bus Local Bus data.
That is, the processor of host-processor/IAC of NFC generally provides pci bus, by special chip, as the most general PCI9030 of PLX company device, this bus can be converted to Local Bus bus, connects ST16C550 again and expands serial ports.
Described management channels can also be two ethernet ports, first adaptation layer and second adaptation layer, two described ethernet ports are respectively the 5th ethernet port and the 6th ethernet port, perhaps distinguish multiplexing first ethernet port and second ethernet port, perhaps distinguish multiplexing three-ethernet port and the 4th ethernet port.That is, two ethernet ports that two ethernet ports of management channels can the multiplex data passage, two ethernet ports that also can multiplexing status protocol passage can also be reset two ethernet ports as management channels.Described first adaptation layer, be arranged on the host-processor of NFC or be connected in the host-processor of NFC, be used for the data of serial ports form and the conversion between the Ethernet message, described second adaptation layer, be arranged on the processor of IAC or be connected in the processor of IAC, be used for the data of serial ports form and the conversion between the Ethernet message.
The conversion that first adaptation layer and second adaptation layer are used between serial ports formatted data and the Ethernet message has a lot of modes.Such as, the adaptation layer of transmitting terminal is filled into the data field of an Ethernet message with 8 Bits Serial data of a serial ports form, and the sign of this message carrying serial data is filled into the Ethernet heading of this Ethernet message.The adaptation layer of receiving terminal is converted to serial data with the Ethernet message: obtain one 8 Bits Serial data and form a string mouthful of formatted data from the data field of Ethernet message.
See also Fig. 4, the embodiment schematic diagram that it is connected with IAC for NFC of the present invention.Data channel, status protocol passage are to realize by ethernet port separately.The connected mode of described optimum is one or more 10GE Ethernets that bundle.Other Ethernet form also can be used for this interconnection as one or more 10M of bundling, 100M, 1000M Ethernet.The 10GE interconnection can provide higher interface bandwidth, and can simplify the function that the interconnection of low rate ethernet port needs a plurality of multilink bundlings.Management channels is realized by serial port (abbreviation serial ports).Serial ports 1 and serial ports 2 can adopt realizes that 1 UART1 and UART2 realize, open in detail about management channels the foregoing description, just repeats no more at this.
The Ethernet message that NFC will need IAC to handle can carry corresponding source address and/or destination address information send to IAC by this interconnect port processor.After IAC is correspondingly processed, need return in the Ethernet message of NFC, carry corresponding source address and/or destination address information and return to NFC again by this interconnect port.This NFC of needs carries mode that respective sources address and/or destination address information offer IAC and need exchange at dedicated ethernet and carry out the special support that is provided with in the device, so that these source addresses and/or destination address information are carried in the interconnect port as the Ethernet payload between of standard, can be obtained and discern by the processor of IAC like this.If NFC the data message that sends IAC to can not be carried above-mentioned information then the application of this framework is restricted.These data can adopt following two kinds of ethernet frame formats to be implemented in and carry source address and/or destination address in the Ethernet message.
The privately owned Higig/Higig+ agreement that adopts the Ethernet switching asic of Broadcom company realizes the data message that the ASIC device inside is handled is carried the source address of this packet and/or destination address information etc.The ethernet frame format of keeping standard is constant, and the Overhead that the Higig/Higig+ agreement is needed is increased in the payload of Ethernet, makes message length change.
The ethernet switch hub spare that Marvell company provides adopts special-purpose packet handler to realize.The ethernet port of the NFC that packet handler docks with IAC is set to the Backend pattern, in the data message encapsulation under this pattern, 6 byte Original MAC DA are original purpose MAC Address of data message, and 6 byte Original MAC SA are original data message source MACs.
Also need between the host-processor of NFC and the processor of IAC to carry out the mutual of status protocol by the status protocol passage.By the status protocol passage mainly is functions such as heartbeat detection, clock synchronization, veneer between NFC and the IAC restarted, state information is mutual.The message that transmits in this status protocol passage can be the Ethernet data message format.In last figure, this status protocol passage adopts a new ethernet port to realize, certainly, ethernet port that also can the multiplex data passage is realized the communication of status protocol information.
