Systems and methods of network packet switching use a table representation of a trie data structure to identify a timestamp (TS) range (or time range) for a received packet based on the packet timestamp (TS). The trie data structure is programmed with a plurality of predetermined time ranges. Each node in the trie data structure corresponds to a TS prefix and is associated with a corresponding predetermined time range. A search engine in the network switch can use the packet TS as a key to traverse the trie data structure and thereby matching the packet TS to a predetermined time range according to a Longest Prefix Match (LPM) process. Provided with the TS ranges of the incoming packets, various applications and logic engines in the network switch can accordingly process the packets, such as determining a new destination IP address and performing channel switch accordingly.

Systems and methods are disclosed for parallelizing service function chains. A method comprises receiving a sequential service function chain comprising a plurality of network functions, receiving a plurality of operations, determining at least two network functions are capable of being parallelized, aggregating operations of the plurality of operations associated with the at least two network functions into a network function segment, determining whether another network function is capable of being parallelized with the network function segment, based on the determining: aggregating an operation associated with the another network function into the network function segment when the another network function is capable of being parallelized with the network function segment, or pushing the network function segment as a completed segment of a hybrid service function chain when the another network function is not capable of being parallelized with the network function segment, and implementing the hybrid service function chain.

An example apparatus includes: at least one memory; instructions in the apparatus; and processor circuitry to execute the instructions to: determine whether a census impression record corresponds to a panelist impression record by: comparing a first internet protocol (IP) address of the panelist impression record with a second IP address of the census impression record; and comparing a first timestamp of the panelist impression record with a second timestamp of the census impression record; and send a comparison result to a computer of an audience measurement entity, the comparison result indicative of a match confirming the census impression record corresponds to the panelist impression record of the audience measurement entity.

A packet destined for a Multi-access Edge Computing (MEC) network is received at a wireless station from a user device. A serving gateway (SGW) receives the packet from the wireless station via an S1U GTP tunnel and assigns an uplink S1U General Packet Radio Service (GPRS) Tunneling Protocol (GTP) tunnel endpoint identifier (TEID) to the packet. The SGW performs a network address translation (NAT) function on the packet based on the uplink S1U GTP TEID assigned to the packet to form a translated packet. The SGW transmits the translated packet to the MEC network.

Techniques for virtualized network functions (VNFs) that provide for domain isolation of networks coupled to the VNF are described. A virtual network function (VNF) includes a cloud virtual domain coupling the VNF to a cloud service, a management virtual domain coupling the VNF to a management service, and an external virtual domain having a public Internet Protocol (IP) address. The external virtual domain receives an authentication request providing access credentials for a VNF customer from a cloud client device, provides the authentication request to the management service via the management virtual domain, receives an authentication response from the management service, and, in response to determining that the VNF customer access credentials are valid, initiates application of a policy that allows the cloud client device to configure the cloud virtual domain or the cloud service and disallows configuration of the external virtual domain and the management virtual domain.

A system and method for providing network and port address translation is provided. A global IP address and a block (chunk) of ports are allocated for each mobile subscriber (MS) on first data connection. Subsequent data connections from the same MS are assigned the same IP address and a new port from this block. The mapping information is communicated, processed, and stored once for the complete block, instead of for every new data connection. This process reduces processing, communication, and storage requirements.
