At the copending application U.S. 12/947678 (entitled " Iterative Parsing and Classification ", lawyer's scheme number No.MP3444) in describe according to an embodiment party The parsing of formula and sort module 18, be herein incorporated by reference of text by its description, except The part (if any) inconsistent with this specification.In another embodiment, Any other suitable hardware and/or component software can substitute for resolving and use with sort module 18 In resolving and categorical data packet.

PHM packet handling module 16 analytically receives the classification 34 of packet with sort module 18. In one embodiment, PHM packet handling module 16 includes that memorizer memory module selects module 20, preextraction module 22, cache registration module 42 and pry module 62.Jointly Pending application U.S. 13/038,258 (entitled " Pre-fetching of Data Packets ", Lawyer's scheme number No.MP3580) in describe the preextraction module according to an embodiment 22, its description is herein incorporated by reference of text, except inconsistent with this specification Partly (if any).

For be network controlled device 12 receive and by resolve and sort module 18 classify each Packet, PHM packet handling module 16 is based on classifying 34 with in multiple memorizer memory modules One or more memorizer memory modules operation.Such as, as hereafter discussed in more detail Like that, PHM packet handling module 16 deposits pattern and pry mould with preextraction pattern, cache One in formula operates.In one embodiment, based on connecing for packet The classification information 34 received, (such as, memorizer memory module selects mould to PHM packet handling module 16 Block 20) select the suitable memorizer memory module for packet.An embodiment party In formula, based on to incoming queue or stream (such as, VOIP, Streaming video, the Internet Browsing session etc.) the classification of packet, the information being included in packet itself, The availability of system resource (such as, as the copending application U.S. _ _ _ _ _ (entitled " Combined Hardware/Software Forwarding Mechanism and Method ", Lawyer's scheme number No.MP3595) described in, by its description by reference of text Be herein incorporated) etc. make the suitable memory memory module for processing packet Select.

The operation of preextraction pattern

In one embodiment, module 20 is selected to divide based on data when memorizer memory module The classification 34 of group selects when the preextraction pattern of packet, at preextraction module 22 Manage this packet.Such as, during preextraction pattern, packet (is network controlled Device 12 receives and is resolved by parsing and sort module 18 and classifies) it is stored in memorizer 26 In.Additionally, preextraction module 22 analytically receives dividing of packet with sort module 18 Class 34.Being based at least partially on the classification 34 of reception, preextraction module 22 is from memorizer 26 Desired part to cache 30 preextraction packet.In one embodiment, in advance Extraction module 22 passes through preextraction module 22 from memorizer 26 to cache 30 preextraction Packet.The packet of preextraction is accessed from cache 30 by processing core 14.

In one embodiment, core 14 request data packet is being processed to perform these data Before the process operation of packet, preextraction module carries to cache 30 in advance from memorizer 26 Take this packet.In one embodiment, the classification 34 of packet includes that data are divided Group is the need of by preextraction module 22 preextraction or whether packet is performed routine and carry The instruction of extract operation (such as, being extracted packet by process core 14 when needed).Therefore In not far future, when expection processes core 14 packet to be used, preextraction module 22 Based on this packet of 34 preextractions of classifying.The copending application U.S. 13/038,258 (name It is referred to as " Pre-Fetching of Data Packets ", lawyer's scheme number MP3580) described in It is suitable for operation and the structure of preextraction module.

In one example, the classification 34 being associated with multiple packets indicates the first data Packet and the second packet belong to and process the same process queue of core 14 (or same place comprehends Words or same Business Stream), and also instruction is to for the first packet and the second data The selection of the operation of the preextraction pattern of packet.Belong at first when process core 14 is processing When managing the first packet of queue, process core 14 and be likely to process be belonged to subsequently and first The first process queue or the second of the identical services stream of process core 14 that packet is identical counts According to packet.Thus, when processing core 14 and processing the first packet, preextraction module 22 from memorizer 26 to cache 30 preextraction the second packet so that process core 14 can when needed (such as, process the first packet after) from cache 30 Access the second packet.Therefore, when processing, core 14 is ready to be divided processing the second data During group, easily can obtain the second packet in cache 30.Preextraction module 22 Preextraction to the second packet decreases and processes the delay that the second packet is associated (for this is compared to following situation: process core 14 will process the second packet time from Memorizer 26 reads the second packet).In one embodiment, preextraction module 22 Receive from process core 14 and be presently processing which packet and/or pass about process core 14 In processing the following information that may process which packet of core 14.

Packet is typically included in the preamble segment before packet payload section.Preamble segment example As included, address, destination-address, priority, queue, business are played in the source with packet Stream, application, the agreement that is associated etc. (such as, any other configuration information) are correlated with The information of connection.Payload section such as includes that the user data that is associated with packet is (such as, It is intended to the data transmitted by network, such as internet data, stream media etc.).

In some applications, process core 14 only needs access data to divide when processing packet The section of group.In one embodiment, classification 34 instruction of packet will be by processing core 14 The section of the packet accessed.In one embodiment, the whole data of preextraction are replaced to divide Group, preextraction module 22 is based at least partially on the classification 34 of reception, from memorizer 26 to The section of cache 30 preextraction packet.In one embodiment, with packet The classification 34 being associated indicates the section of packet, and preextraction module 22 will be from memorizer 26 Section to cache 30 this packet of preextraction.That is, resolve and sort module 18 base In the classification to packet, select preextraction module 22 by preextraction from memorizer 26 The section of packet.

In one example, process core 14 only to need to access and process and network route application phase The preamble segment of the packet of association.On the other hand, process core 14 need access and process with The preamble segment of the packet that safety-relevant applications is associated and payload section.A reality Execute in mode, resolve and sort module 18 identifies the packet that network controller 12 receives Type.Such as, peace is had been previously identified as if resolving to identify with sort module 18 to be derived from The packet in the source of full property risk, then resolve and sort module 18 be by this sorting packets It is associated for security-related application.In one embodiment, resolve and sort module 18 (such as, whether packet route application, safety with network to the type of identification packet Related application etc. are associated), and correspondingly generate classification 34.Such as, based on classification 34, The preamble segment of the packet that preextraction module 22 only preextraction is associated with network route application (or part of preamble segment).On the other hand, preextraction module 22 preextraction and safe phase Close the preamble segment of another packet that application is associated and payload section (or of preamble segment Divide and/or a part for payload section) both.

In another example, classification 34 is based at least partially on be associated with packet excellent First level.Preextraction module 22 is from the precedence information of classification 34 reception packet.For The packet of relatively high priority is (such as, with real-time audio and/or Video Applications (such as Internet protocol voice (VOIP application)) packet that is associated) for, such as, Preextraction module 22 preextraction preamble segment and payload section are (because processing core 14 may Need to access payload section after access the preamble segment of packet from cache 30). But, for the packet of relatively low priority, preextraction module 22 only preextraction Preamble segment (and, such as, based on processing core 14, the needs of payload section are extracted payload section). In another embodiment, for the packet of another relatively low priority, carry in advance Delivery block 22 not preextraction packet, and and if only if process core 14 to be actually needed this data During packet, just extract this packet from memorizer 26 to cache 30.

In other examples another, preextraction module 22 is based at least partially on any other and closes Suitable standard carrys out the section of preextraction packet.Such as, preextraction module 22 is at least in part The section of preextraction packet is carried out based on any other configuration information in classification 34.

Cache deposits the operation of pattern

In one embodiment, module 20 is selected to divide based on data when memorizer memory module The classification 34 of group selected when the cache of packet deposits pattern, and cache is posted Storing module 42 processes packet.Such as, during cache deposits pattern, the most slow Deposit registration module 42 and receive classification 34, and optionally instruction network controller 12 is being deposited Reservoir 26 and/or cache 30 store packet.In one embodiment, exist During cache deposits pattern, network controller 12 is based at least partially on and comes from a high speed The instruction of caching registration module 42, stores the section of packet in cache 30, and And in memorizer 26, store another section (or whole packet) of this packet.Example As, the section only processing the packet that core accesses when processing packet is stored in the most slow Deposit in 30.

In one embodiment, the classification 34 being associated with packet indicates network control Device 12 will be stored directly in cache 30 (such as, by bypass registers 26) The section of packet.That is, resolve and sort module 18 is based on the classification to packet, choosing Select network controller 12 by the section of the packet that is stored directly in cache 30 (but Being in another embodiment, different assemblies (the most not shown) receives classification 34, And determine which section by storing packet in cache 30).

Such as, packet includes multiple byte, and network controller is to cache 30 N number of byte (such as, the top n byte of packet) of storage packet, and Store remaining byte of packet to memorizer 26, wherein N is integer, and this N is such as By resolving and sort module 18 (such as, classification 34 includes the instruction of Integer N) and/or height Speed caching registration module 42 (such as, based on classification 34) selects.

In another example, network controller stores the N number of of packet to cache 30 Byte, and also to memorizer 26 store whole packet (thus, the N of packet Individual byte is stored in both cache 30 and memorizer 26).

As it has been described above, the section of packet is only stored in cache by network controller 12a In 30, processing core 14 needs to access the section of this packet when processing packet.One In individual embodiment, packet includes first paragraph and second segment, and network controller 12 The first paragraph of packet is directly transmitted (as at a high speed to cache 30a based on classification 34 Caching deposits a part for pattern), but prevent and transmit packet to cache 30a Second segment (network controller 12 transmits the second segment of packet to memorizer 26, can Can also have first paragraph).

In one example, as it has been described above, process core 14 and only need to access and process and network The preamble segment of the packet that route application is associated.Thus, resolve and sort module 18 is raw Become the classification 34 of this type of packet.In one embodiment (such as, if classification 34 Also instruction cache deposits the operation of pattern), (such as, except or replace to memorizer 26 preamble segment storing these packets), network controller 12 is based on classifying 34 to height Preamble segment that speed caching 30 only stores these packets (or replace storing whole preamble segment It is only to store the relevant portion of preamble segment).

In another example, process core 14 need access and process security-related application be correlated with The preamble segment of the packet of connection and payload section.Thus, resolve and sort module 18 is raw Become the classification 34 of this type of packet.In one embodiment (such as, if classification 34 Also instruction cache deposits the operation of pattern), (such as, except or replace to memorizer 26 preamble segment storing these packets), network controller 12 is based on classifying 34 to height Speed caching 30 only stores the preamble segment of these packets and payload section and (or replaces storage whole Preamble segment, only stores the relevant portion of preamble segment).

In one embodiment, it is based at least partially on be associated with packet preferential Level generates classification 34.Such as, cache registration module 42 is divided from classification 34 reception data The precedence information of group.For the packet of relatively high priority, network controller 12 based on classification 34 store in cache 30 preamble segment and payload section (because, Process core 14 may need access from cache 30 packet preamble segment later Access payload section).For the packet of relatively low priority (such as, for belonging to phase For packet categorized in the classification 34 of low priority flows/queue) for, network controls Device 12 only stores preamble segment to cache 30 based on classification 34.In another embodiment, For the packet of another relatively low priority, network controller 12 is not the most slow Deposit store packet in 30 any section, and instead, select another suitably to store Device memory module (such as, selects preextraction pattern).In other examples, network controls Device 12 is based at least partially on any other suitable standard (such as, appointing in classification 34 What his configuration information), cache 30 stores the section of packet.

Snoop mode

In one embodiment, module 20 is selected to divide based on data when memorizer memory module The classification 34 of group selects when the snoop mode of packet, and pry module 62 processes number According to packet.In one embodiment, during snoop mode, it is based at least partially on point Class 34, pry module 62 passes through bus 60 from network interface 12 to memorizer in packet Snoop data packet during 26 transmission.In one example, based on classification 34, spy upon module 62 Only snoop transactions core 14 needs the section of the packet accessed when processing packet.Such as, Classification 34 includes the instruction of the section by the packet spied upon by pry module 62.

In one embodiment, snoop mode is independent of preextraction pattern and/or cache The pattern of depositing operates.In one embodiment, pry module 62 is based on corresponding classification 34 pry, from the section of all packets that network controller 12 transmits to memorizer 26.

In (such as, support that hardware cache is conforming) conventional packet communication system, All packets that pry or sniff are transmitted to memorizer are to guarantee cache coherence. Generally, this type of snoop (such as, checks the most whether there is number to check According to effective copy, and if in memorizer correspondent section write new data, then make height Effective copy of the data in speed caching is invalid) packet communication system can be made to overload (such as, Owing to each affairs of writing for memorizer complete pry).On the contrary, pry module 62 selects Property ground only snoop transactions core 14 need the section of packet accessed (such as, to replace whole number According to packet), thus reduce the process load of the system 10 being associated with pry.

In one embodiment, snoop mode combines another memorizer memory module and grasps Make.Such as, based on classification 34, during cache deposits pattern, to memorizer 26 The Part I of write packet, and the of packet is directly write to cache 30 Two parts.In one embodiment, first of packet is being write to memorizer 26 Timesharing, pry module 62 can be with the Part I of snoop data packet.Therefore, in this example In, snoop mode combines cache and deposits pattern execution.In one embodiment and The classification 34 for packet is generated with sort module 18 as it has been described above, resolve so that point Class 34 indicates PHM packet handling module 16 to operate which or which module when processing packet.

In one embodiment, packet includes multiple byte, and spies upon module 62 Only M byte (such as, front M the byte of the packet) (example of snoop data packet As, replace spying upon whole packet), wherein M is such as to be associated with packet Classification 34 in instruction integer.In one embodiment, pry module 62 is not spied upon Remaining byte (such as, the byte outside M byte) of packet.

In one embodiment, classification 34 example of the section of packet that instruction will be spied upon Type of based on packet in this way.Such as, process core 14 only need access and process with The preamble segment of the packet that network route application is associated.Thus, at an embodiment In, generate classification 34 so that pry module 62 the most only spies upon these numbers based on classification 34 The preamble segment relevant portion of preamble segment (or only) according to packet.In another example, process Core 14 accesses and processes preamble segment and the payload of the packet that security-related application is associated Both sections.Thus, in one embodiment, generate classification 34 and make to spy upon module 62 The preamble segment of packet that pry is associated with safety applications and payload section (or only preamble segment And/or the relevant portion of payload section).

In another example, classification 34 based on the packet for the queue selected or stream, Pry module 62 is based at least partially on (such as, the classification 34 of any other suitable standard In any other configuration information), come snoop data packet section.

The operation of system 10 in Fig. 1

As it has been described above, based on the classification information 34 for data packet receipt, packet transaction mould Block 16 (such as, memorizer memory module selects module 20) selects the conjunction for packet Suitable memorizer memory module (such as, preextraction pattern, cache deposit pattern and One or more in snoop mode).Such as, network controller 12 can be by relatively high excellent The packet of first level (such as, the packet of whole high priority or only high priority The relevant portion of packet) directly write to cache 30.That is, for high priority Packet for, classification 34 can be generated so that memorizer memory module select module 20 select cache to deposit pattern.In another example, pry module 62 can be spied upon whole The packet of individual high priority.On the other hand, the number of medium priority is write to memorizer 26 According to packet (such as, but have lower than the packet of high priority than low priority The packet of the priority that packet is high), and then can access processing core 14 And before processing packet, by preextraction module 22 preextraction.That is, for medium priority Packet, classification 34 can be generated so that memorizer memory module select module 20 Select preextraction pattern.The packet of low priority can be stored in memorizer 26, And and if only if process when process is grouped by core 14 and extract to cache 30.Additionally, at another In example, pry module 62 only can spy upon based on the classification 34 being associated medium priority with/ Or the section of the packet of low priority.

As it has been described above, based on classification 34 (priority based on such as packet then) with Preextraction pattern, cache deposit pattern and/or snoop mode to carry out operating be only example. In another example, it is also possible to by any different in the way of generate classification 34.

As it has been described above, in one embodiment, in various memorizer memory modules, example As, replacement processes whole packet, only process the section of packet (this process such as, Only preextraction, deposit in cache 30 and/or snoop data packet section).Such as, Only the section of the packet accessed is needed to be placed at a high speed when processing packet by processing core 14 In caching 30 (such as, with preextraction pattern or depositing pattern with cache).Therefore, No matter processing when core 14 desires access to and/or process packet, processing core 14 and all can hold Change places in cache 30, obtain the section of packet, thus decrease and process data and divide The delay that group is associated.The section being additionally, since only packet (such as, replaces whole number According to packet) storage in the caches, thus cache does not overload because of data (example As, it is not necessary to frequently override cache).This also results in the cache that size is less, And/or reduce the chance washing away packet from cache.

In one embodiment, resolve and sort module 18, preextraction module 22, at a high speed Caching registration module 42 and/or pry module 62 are fully configurable.Such as, resolve and Sort module 18 can be arranged to the SOC being based at least partially on application He being associated Key, the type of packet, available bandwidth etc., dynamically change segment data The selection of packet (such as, will be with preextraction pattern or deposit pattern with cache and stored In the caches or the segment data spied upon is grouped).In another example, in advance Extraction module 22, cache registration module 42 and pry module 62 can be arranged to move The change of state ground such as inserts the timing of the section of packet (such as, to carry in advance to cache Delivery formula or deposit pattern with cache), and/or dynamically change the system 10 with Fig. 1 Any other appropriate criteria of being associated of operation.

Fig. 2 shows according to embodiment of the present disclosure, for operating the system 10 of Fig. 1 Exemplary method 200.204, network controller 12 (or any other of system 10 is suitable Assembly) receive the packet transmitted by network.208, resolve and sort module 18 Generate the classification information for packet.In one embodiment, classification 34 includes using Instruction in the memorizer memory module of packet.In one embodiment, classification 34 Including being such as stored in cache 30 (such as, with preextraction pattern or with at a high speed Caching deposits pattern) and/or by the instruction of the section spying upon the packet that module 62 is spied upon.

212, memorizer memory module selects module 20 to deposit based on classification 34 selection memorizer Storage pattern.216, PHM packet handling module 16 uses at the memorizer memory module selected Reason packet.Such as, if selected for preextraction pattern, then store number to memorizer 26 According to packet, and preextraction module 22 is based at least partially on classification 34, from memorizer 26 Section to cache 30 preextraction packet.In another example, if selected for height Speed caching deposits pattern, then be based at least partially on classification 34, directly from network controller 12 The section of packet is stored to cache 30.In another example, if selected for pry Pattern, then pry module 62 be based at least partially on classification 34, by bus 60 to depositing The section of snoop data packet when reservoir 26 writes packet.In one embodiment, peep Spy pattern deposits pattern (such as, snoop mode independent of preextraction pattern and/or cache Whether all packets for write memorizer 26 perform, such as, and select to carry in advance It is unrelated that delivery formula and/or cache deposit pattern).
