Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a packet loss processing method, apparatus, device, and machine-readable storage medium.
Background
A Counter, a register for counting operations or messages in the hard-turn mechanism.
CAR (Committed Access Rate), used for traffic policing, is a method for guaranteeing network quality of service.
SNMP (Simple Network Management Protocol) is a standard Protocol specifically designed for managing Network nodes (servers, workstations, routers, switches, HUBS, etc.) in an IP Network, and is an application layer Protocol. SNMP enables a network administrator to manage network performance, discover and solve network problems, and plan for network growth. The network management system receives the random message (and the event report) through the SNMP to know that the network has problems.
The NMS (Network Management System) is an operation and maintenance center, and is responsible for device fault diagnosis and operation and maintenance of the wireless access System, Network operation and Network Management, and provides data and statistics for Network Management and planning. The management objects of the NMS may include all the entities in the network, such as: network devices, applications, server systems, routers, switches, HUBs, auxiliary devices (e.g., UPS power), etc., provide a system-wide view of the network to the network system administrator.
ARP (Address Resolution Protocol) is a TCP/IP Protocol that obtains a physical Address from an IP Address. When the host sends information, the ARP request containing the target IP address is broadcasted to all the hosts on the local area network, and the return message is received, so that the physical address of the target is determined; after receiving the return message, the IP address and the physical address are stored in the local ARP cache and are kept for a certain time, and the ARP cache is directly inquired when the next request is made so as to save resources.
Current computer networks can be classified into three categories according to their distance and complexity: local Area Networks (LANs), metropolitan area networks (MANs and Wide Area Networks (WANs), LANs are the simplest of the most primitive computer networks, typically using only one transmission medium, consisting of computers and workstations interconnected over short distances, usually within a building, in order to share resources, such as printers, and exchange information MAN is a larger network than LAN, there may be multiple media, typically covering a city, with relatively complex mid-range communication network devices; a MAN is typically connected to a plurality of LANs-a complex network system across a large territory that provides data sharing for users distributed in different territories, typically requiring leased operator lines, -two or more LANs may be connected via a WAN, the connections between these LANs may span distances of tens of kilometers or more, a large WAN may even connect many LANs and MANs of various provinces.
A more sophisticated network, apart from a large number of clients at the network end, has numerous devices interspersed and concentrated, including two-tier switches, three-tier switches, DSLAMs, BAS, routers, servers, storage devices, etc. In a large MAN or WAN network system, the number of messages processed per second of network devices such as these switches and routers is counted as 100G bits, wherein the messages related to network protocol interaction are generally analyzed and processed by a CPU, which is called as soft switching, and a large number of data messages (web page access, video traffic, etc.) are mostly forwarded and processed by querying hardware table entries (such as FIB table, ACL table, etc.) by a forwarding chip, that is, hard switching, because the soft switching performance is limited.
The soft switching is flexible, the CPU programming language can analyze the message in the memory very conveniently, and at the same time, detailed records are made on the forwarding and discarding of the message, but the CPU processing performance is limited and the cost is high, and to support the current MAN/WAN network level message forwarding, a hard switching mode must be used, but the hard switching has its defect, that is, the chip hardware program is solidified, and detailed analysis and recording of the message cannot be supported, otherwise, the forwarding performance is also degraded, that would cause the hard switching to record the discarding of the message very limited, and it is difficult to find the reason for packet loss of a certain message in the network.

The network device forwards the packet loss count by hardware, and can simply query the count of each forwarding flow and the packet loss position reason of the routing device, such as the packet loss due to route miss, the car rate-limiting packet loss, the check error packet loss and the like. And then, manually reproducing the current scene and equipment configuration, networking and streaming, analyzing a special forwarding flow, manually comparing related hardware forwarding table items and packet loss positions, and finding out the reason of packet loss.
However, the packet loss records are only counted, and do not contain more user-friendly information, and a large amount of manpower and material resources are required to be consumed to locate the reason for packet loss. Meanwhile, the current network environment cannot be worked when packet loss is checked.
In view of the above, the present disclosure provides a packet loss processing method, a packet loss processing apparatus, an electronic device, and a machine-readable storage medium, so as to solve the problem that it is difficult to efficiently record packet loss.
The specific technical scheme is as follows.
In an embodiment, the present disclosure provides a packet loss processing method, applied to a forwarding chip of a network device, where the method includes: acquiring message information of a packet loss message with a packet loss, inquiring a packet loss record table according to the message information, and judging whether a corresponding packet loss record table item exists; if the corresponding packet loss record table entry exists, updating the counting field of the packet loss record table entry; sending the packet loss record table to a processing device so that the processing device can analyze packet loss according to the packet loss record table; the packet loss record table entry comprises a message information field and a counting field.
Specifically, as shown in fig. 1, the method comprises the following steps:
step S11, obtaining the packet information of the packet loss packet in which the packet loss occurs, querying the packet loss record table according to the message information, and determining whether the corresponding packet loss record table entry exists.
The message information includes destination IP address, source IP address, protocol type, destination port, and source port.
Step S12, if there is a corresponding packet loss record entry, the count field of the packet loss record entry is updated.
E.g., the value of the count field is incremented by 1.
Step S13, sending the packet loss record table to the processing device, so that the processing device performs packet loss analysis according to the packet loss record table.
The processing device may be a CPU of the present device, or may be another device such as a server.
The packet loss record table entry includes a message information field and a count field.
The packet loss condition is recorded to the packet loss record table through the hardware forwarding chip during hard forwarding, so that the packet loss of the message can be conveniently recorded under the condition of not sacrificing performance, and then the packet loss record table is sent to a device special for analyzing the packet loss so as to quickly analyze and determine the packet loss condition.
In an embodiment, the querying, according to the message information, the packet loss record table, and determining whether a corresponding packet loss record table entry exists, includes: and if the corresponding packet loss record table entry does not exist, establishing the corresponding packet loss record table entry in the packet loss record table according to the message information, and setting the value of the counting field as an initial value.
If no corresponding packet loss record entry exists, it indicates that the packet loss of the flow occurs for the first time, so a corresponding packet loss record entry is created in the packet loss record entry according to the message information, and the value of the count field is set as an initial value, for example, set to 1.
In an embodiment, the creating a corresponding packet loss record entry in the packet loss record table according to the packet information includes: and according to the type of the packet loss, creating a corresponding packet loss record table entry at a corresponding address of the packet loss record table.
Even if different address segments correspond to different packet loss types, corresponding table entries are created to corresponding positions according to the packet loss types, and when the packet loss recording table is analyzed, the corresponding packet loss types can be confirmed according to the addresses of the table entries. The same flow can correspond to a plurality of different packet loss types, table entries can be respectively created in address intervals of different packet loss types in a packet loss type table, and when a packet loss record table is inquired according to message information, the table entries are required to be searched in corresponding address fetching pieces according to the packet loss types.
As a technical solution, the packet loss record table entry includes a packet loss type field; the creating of the corresponding packet loss record table entry in the packet loss record table according to the message information includes: and creating a corresponding packet loss record table entry in the packet loss record table according to the message information and the type of the packet loss.
And increasing a storage space to record a packet loss type, and matching the packet loss type and the message information at the same time when inquiring a packet loss record table according to the message information.
In the processing flow of the hardware forwarding chip, an entry (packet loss record entry) and a counter for newly adding and recording packet loss numbers are added, for example, the name of the newly added entry is a packet drop table, the same quintuple (DIP, SIP, protocol type, DPORT, port, destination IP address, source IP address, protocol type, destination port, source port) is marked as one stream, a packet information field of the packet drop table is a packet quintuple, a count field of the newly added counter needs to be determined according to the number of traffic and packet loss reasons, for example, 128K traffic packet loss can be recorded in each device, and the traffic packet loss types are three (can be expanded according to different packet loss types): routing miss packet loss, CAR speed limit packet loss and Check error packet loss, so that the total number of counters required by us is 128K × 3, different Counter base addresses are allocated for the three packet loss reasons, a router skip (routing miss packet loss) base address is 0, a CAR drop (CAR speed limit packet loss) base address is 128K, a Check drop (Check error packet loss) base address is 256K, the base address is a fixed value, only Counter offset ids (only corresponding to different five-tuple) are stored in a packet drop table entry, and corresponding packet loss counts are stored in a table entry of the base address + Counter offset id of a corresponding packet loss type.
A default table entry with the lowest priority can be added for the initialization of the Packet drop table, the quintuple of the message is not concerned, all discarded messages are matched, the action of uploading the discarded messages to a CPU is performed, and the total number of the discarded packets can be recorded.
The flow is firstly subjected to hard rotation by equipment, the message passing through the hard rotation table entry is judged to be normally transmitted, if the three reasons are lost, the message to be discarded can hit the last default table entry of the packet drop and be transmitted to the CPU, the CPU receives the discarded message, analyzes the message quintuple and transmits a formal quintuple packet drop table entry, dynamically applies for Counters resources to obtain a Counter offset id write-in table entry result, and discards the message after the count +1 (the value of the newly-built table entry is 1 after the action).
If packet loss occurs due to the three reasons, inquiring a packet drop table entry according to a packet quintuple, counting the number of +1 times and discarding the packet according to the Counter offset id in the table entry and the base address of the corresponding packet loss type after hitting;
and after the hard switching equipment process is realized, packet loss reason counts of 128K different quintuple flows are obtained, including all history records.
When the 128K capacity is insufficient due to the accumulated records, the packet loss data is collected and stored through an additional server, so that the network equipment leaves out new entries to store more packet loss records, and the data can be uploaded in real time or periodically.
One packet loss server can be used for collecting and storing packet loss conditions of a plurality of network devices in one area, the server collects packet loss information of the network devices at regular time, the collection time is recorded as a reference, the collected data is analyzed in a unified mode, the packet loss in the wrong mode, the protocol packet loss and the like can be analyzed to determine whether the adjacent network devices have problems, a user can also set packet loss number monitoring, and alarm is carried out when the flow of some DIPs or SIPs exceeds a packet loss threshold.
The connection and transmission between the packet loss server and the network device can be done using SNMP. SNMP (Simple Network Management Protocol) is widely used for remote Management and operation of Network devices. SNMP allows an administrator to manage devices of different vendors, different physical characteristics, different interconnect technologies on the network through NMS, including status monitoring, data collection, and fault handling. The protocol can support a network management system to detect whether any devices connected to the network are of any regulatory concern. The packet loss server can exist as a network management system and interacts with managed network equipment by using an SNMP protocol.
When the administrator analyzes the packet loss problem of a certain message in an area, firstly, the corresponding message is searched in the packet loss server, and the packet loss type of the current message can be checked. When the packet loss type is special, the problem cannot be found at a glance, the hardware table entry in the period of time can be analyzed by combining the device log in the packet loss acquisition time, the environment in the packet loss is recovered, and the related table entry corresponding to the packet loss type is further analyzed.
When the number of packet losses in an area is large, an administrator can inquire the count of each packet loss type and analyze the packet loss type with the largest count. If a large amount of packet losses due to the depletion of TTL, it may be determined that a routing loop exists in the device in the area, and at this time, a fast forwarding table or an ARP table of all devices in a certain time range is called for analysis, so that the routing loop may be discovered which devices constitute the routing loop.
