Some examples relate to distributing application classification entries to network devices. An example includes receiving, by a processing resource in a cloud computing system, an application classification entry for an application from respective network devices on a network. The application classification entry may comprise a given application identifier for identifying the application and control information for routing a network packet originating from the application. For the given application identifier, the processing resource may generate a consolidated set of application classification entries, based on the application classification entry received from respective network devices. The processing resource may then determine appropriate network devices to distribute the consolidated set of application classification entries.

A data processing system having an address resolution function for deriving MAC addresses. The set of MACs defined for the devices on the network encode physical position or logical identifier information of those devices. Therefore, each of these MACs is derivable using a mapping function that maps the physical position or logical identifier information supplied by an application to the MAC addresses of the devices on the network. When the protocol processing entity has to send data over the network, it can obtain the MAC address for the destination determined on the basis of the physical position or logical identifier supplied by the application. In this way, since the MACs are derivable on the basis of the physical positions or logical identifiers, the broadcasting of ARP request messages, which would otherwise be required when the protocol processing entity requires the MAC for the destination, may be avoided.

A system, process, and computer-readable medium for updating an application cache using a stream listening service is described. A stream listening service may monitor one or more data streams for content relating to a user. The stream listening service may forward the content along with time-to-live values to an application cache. A user may use an application to obtain information regarding the user's account, where the application obtains information from a data store and/or cached information from the application cache. The stream listening service, by forwarding current account information, obtained from listening to one or more streams, to the application cache, reduces traffic at the data store by providing current information from the data stream to the application cache.

The embodiments of the present disclosure provide a data packet processing method and apparatus, a storage medium and an electronic device. The method includes that: a Bit Index Explicit Replication (BIER) Multicast Identifier (BMID) information of a data packet is set, wherein the BMID information is used for indicating a multicast channel to which the data packet belongs; and the BMID information is sent to a Bit-Forwarding Ingress Router (BFIR). Through the solution in the embodiments of the present disclosure, the technical problem in the related art that a node receives duplicate data packets is solved, duplicate data packets may be prevented, and data transmission efficiency is improved.

A multicast data packet processing method performed by an intermediate node of a multicast tree includes: receiving a first Bit Index Explicit Replication (BIER) packet including a first label; obtaining, according to the first label, a second label corresponding to a multicast tree including the intermediate node; and obtaining a second BIER packet according to the second label and the first BIER packet, and sending the second BIER packet which includes the second label.

A method for establishing a connection between two nodes in a communication network without use of a centralized directory or mapping identifiers includes: receiving a lookup message from another node in the communication network that includes a lookup term; determining if a target node in a local directory cache can be identified that satisfies the lookup term; and, if such a node is identified, establishing a connection to the target node and forwarding the lookup message, or, if no such node is identified, forwarding the lookup message to other nodes in the network with which the node has an active communication connection.

A method and apparatus for establishing a fast-forwarding table are provided. The method comprises: when a communication packet is received, determining, according to matching rules of services set in a packet processing policy, a target service matching the communication packet; if a fast-forwarding table corresponding to the communication packet is not stored locally, obtaining a preset target priority of the target service, and determining a target resource utilization threshold corresponding to the target priority according to a preset correspondence between priorities and resource utilization thresholds; determining whether a current resource utilization is greater than the target resource utilization threshold; and establishing a fast-forwarding table corresponding to the communication packet if the current resource utilization is not greater than the target resource utilization threshold. With this disclosure, the memory pressure of the network device can be reduced, and the network device can be avoided to hang or restart.

An information processing apparatus includes a memory and a processor coupled to the memory. The memory is configured to store device connection information indicating a connection destination device coupled to a first device among a plurality of devices included in a communication network. The processor is configured to: search physical address learning information of the connection destination device in preference to physical address learning information of search target devices other than the connection destination device on basis of the device connection information. The physical address learning information of a specific device includes physical addresses learned for every port of the specific device. The search target devices are the plurality of devices other than the first device. The processor is configured to: obtain a connection destination port coupled to a first port of the first device on basis of a result of the search.

An algorithmic TCAM based ternary lookup method is provided. The method stores entries for ternary lookup into several sub-tables. All entries in each sub-table have a sub-table key that includes the same common portion of the entry. No two sub-tables are associated with the same sub-table key. The method stores the keys in a sub-table keys table in TCAM. Each key has a different priority. The method stores the entries for each sub-table in random access memory. Each entry in a sub-table has a different priority. The method receives a search request to perform a ternary lookup for an input data item. A ternary lookup into the ternary sub-table key table stored in TCAM is performed to retrieve a sub-table index. The method performs a ternary lookup across the entries of the sub-table associated with the retrieved index to identify the highest priority matched entry for the input data item.
