Avoiding recirculation of data packets in a network device
In one embodiment, a method is provided. The method includes receiving a data packet via an ingress interface of the network device. The method also includes determining whether the data packet comprises an Internet Protocol version 4 (IPV4) or an Internet Protocol version 6 (IPV6) packet. The method further includes in response to determining that the packet comprises an IPV4 packet, identifying a first entry in an adjacency table. The first entry is associated with an address prefix. The address prefix is associated with first Internet Protocol (IP) address of the data packet. The first entry indicates a next hop for the data packet. The adjacency table comprises a second entry associated with the address prefix. The method further includes forwarding the packet to the next hop indicated by the first entry in the adjacency table, via an egress interface of the network device.

Wireless extension of broadband access
Methods, systems, and apparatuses are described for extending a network through the use of access nodes. The access nodes may receive packets from user devices via wireless networks. The packets may be routed to a remote server for further network access. The access nodes may communicate with the user devices using network addresses associated with the wireless networks.

MANAGING IP ADDRESSES FOR DPDK ENABLED NETWORK INTERFACES FOR CLOUD NATIVE PODS
The present disclosure provides example computer-implemented method, medium, and system for managing IP addresses for DPDK enabled network interfaces for cloud native pods. One example method includes creating a pod of one or more containers, where the pod connects to multiple networks through multiple network interfaces. A poll mode driver (PMD) is attached to a first network interface of the multiple network interfaces, where the PMD enables one or more data plane development kit (DPDK) applications inside the pod to manage the first network interface. A first container network interface (CNI) is created to handle the DPDK enabled first network interface. A first Internet protocol (IP) address is allocated to the first network interface using the first CNI. The first IP address is passed to the one or more DPDK applications using the first CNI.

PERFORMANCE IMPROVEMENT OF IPSEC TRAFFIC USING SA-GROUPS AND MIXED-MODE SAS
Some embodiments provide a method of load balancing data message flows across multiple secure connections. The method receives a data message having source and destination addresses formatted according to a first protocol. Based on the source and destination addresses, the method selects one of the multiple secure connections for the data message. Each of the secure connections handles a first set of connections formatted according to the first protocol and a second set of connections formatted according to a second protocol that is an alternative to the first protocol. The method securely encapsulates the data message and forwards the encapsulated data message onto a network. The encapsulation includes an identifier for the selected secure connection.

Address management method and system, and device
An address management method, system, and device to avoid a problem that a same Internet Protocol (IP) address is assigned to different packet data unit (PDU) sessions and to effectively use IP addresses in an address pool. The method includes: obtaining, by a session management network element, an identifier of a user plane function network element serving a terminal and session information of the terminal; determining, by the session management network element based on the identifier of the user plane function network element and the session information, an address pool identifier corresponding to the session; sending, by the session management network element, the address pool identifier to a server, where the address pool identifier is used to assign an IP address to the session; and receiving, by the session management network element from the server, the IP address corresponding to the session.
