A novel algorithm for packet classification that is based on a novel search structure for packet classification rules is provided. Addresses from all the containers are merged and maintained in a single Trie. Each entry in the Trie has additional information that can be traced back to the container from where the address originated. This information is used to keep the Trie in sync with the containers when the container definition dynamically changes.

Described herein are systems and methods for suppressing inbound payload to an integration flow of an orchestration based application integration. The systems and methods described herein can, based upon a scan of an integration, identify and exclude from memory certain portions of one or more payloads that are received at the integration flow.

PCIe devices installed in host computers communicating with service nodes can provide virtualized and high availability PCIe functions to host computer workloads. The PCIe device can receive a PCIe TLP encapsulated in a PCIe DLLP via a PCIe bus. The TLP includes a TLP address value, a TLP requester identifier, and a TLP type. The PCIe device can terminate the PCIe transaction by sending a DLLP ACK message to the host computer in response to receiving the TLP. The TLP packet can be used to create a workload request capsule that includes a request type indicator, an address offset, and a workload request identifier. A workload request packet that includes the workload request capsule can be sent to a virtualized service endpoint. The service node, implementing the virtualized service endpoint, receives a workload response packet that includes the workload request identifier and a workload response payload.

Packet routers route data packets based on existing topology files. The packet routers hash the existing topology files into content-addressed objects and exchange the content-addressed objects. One of the routers modifies its topology file into a new topology file, hashes the new topology file into a new content-addressed object, and transfers the new content-addressed object to the other packet routers. The packet routers exchange the content-addressed objects, and in response, exchange the topology files. The routers establish a consensus on the new topology file based on the existing topology files. The one packet router routes additional data packets based on the new topology file in response to the consensus. In some examples, the content-addressed objects comprise Inter-Planetary File System (IPFS) objects.

A network device may receive an instruction to update a data structure implemented by the network device and update the data structure based on receiving the instruction. The data structure may include a routing instruction to direct the network device to provide a data flow to a server device for processing. The network device may receive the data flow destined for a destination device; determine the routing instruction based on at least a portion of an internet protocol (IP) address associated with the data flow and based on the data structure; execute the routing instruction to provide the data flow to the server device and to cause the data flow to be processed by the server device to form a processed data flow; and receive the processed data flow and provide the processed data flow towards the destination device.

Methods and systems anchor hypertext transfer protocol (HTTP) level communication in an information-centric networking (ICN) network. Both content requests and responses to servers within the ICN network and to servers located outside the ICN network, in an IP network for example, are disclosed. Communication may be between two IP capable only devices at the HTTP level, one connected to an ICN network while the other one is connected either to an ICN or IP network. The disclosed namespace 200 enables IP based HTTP communication within the ICN network. An information-centric networking (ICN) network attachment point (NAP) or border gateway (BGW) may receive an HTTP request packet and encapsulate the received HTTP request packet. The ICN NAP/BGW may then forward the HTTP request packet towards the local ICN network servers. The HTTP request packet may be published to a named content identifier (CID) that may be determined through a hash function of a fully qualified domain name (FQDN). The ICN NAP may receive a HTTP response packet for a subscribed information item, which may be included in a named rCID. The named rCID may be determined through a hash function of a uniform resource locator (URL). Instead of using the hash of a URL and an FQDN directly, a separate scope identifier, which may be a root identifier, may be chosen for HTTP-over-ICN communication for the overall ICN namespace. The scope identifier may include a particular structure for the ICN namespace being built up. Using a root identifier may allow for separating HTTP-over-ICN communication from other ICN communication, for example, for operational or migration reasons. Under the root scope identifier, there may be two sub-scope identifiers, a first sub-scope identifier (I) for communication within the ICN network and a second sub-scope identifier (O) for communication to IP addresses outside the ICN network. The ICN may be based on the PURSUIT publish-subscribe architecture or on the Named Data Networking (NDN) project and the like.

Embodiments of the present disclosure provide a method and an apparatus for performing communication in software-defined networking, and a communications system. The method includes: receiving a message sent by a network device, where the message includes a signaling message; determining, according to a control policy, a matching condition that matches the message, where the control policy includes a matching condition and operation information corresponding to the matching condition; processing the message according to the operation information corresponding to the matching condition that matches the message; and sending the processed message to the network device. According to the method and the apparatus for performing communication in software-defined networking, and the communications system in the present disclosure, a problem in the prior art that a control device serving as a network control center cannot communicate with a base station is resolved.
