Abstract: Methods, devices, systems, and non-transitory process-readable storage media include methods for preventing IPv6 address exhaustion in prefix delegation mode by a software-enabled access point (“softAP”) mobile computing device providing an Internet Protocol version 6 (IPv6) wide area network (WAN) connection to a plurality of client devices. A processor of a softAP mobile computing device may include assigning an unassigned prefix of a pool of available prefixes to a client device connected to a local area network (LAN) established by the softAP mobile computing device. The processor may determine whether the client device is disconnected from the LAN based on receiving an indication that the client device has disconnected. The processor may perform a cache look-up to obtain a link-local address of the client device when the client device is disconnected from the LAN, and unassign the prefix associated with the link-local address of the client device.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a network device. The apparatus receives an evolved multimedia broadcast multicast service (eMBMS) data from a base station via multicast transmission. The apparatus transmits the received eMBMS data to one or more end nodes via unicast transmission. In an aspect, the one or more end nodes are connected to the network device via a local area network (LAN).

Abstract: Systems and methods for performing efficient network address (NAT) translation are described herein. In some aspects, partial NAT entries are created for data packets before all the IP fragments of the data packets are received. Further, the IP fragments are transmitted before all the IP fragments of the data packets are received. In some aspects, unique IP-IDs are generated for IP fragments and/or data packets at a NAT device.

Abstract: This disclosure describes systems, methods, and apparatus for using a NATTYPE module in a Linux kernel to carry out Full Cone NAT and address-restricted cone NAT while offloading NAT functionality to a hardware accelerator. The NATTYPE module can be configured to create a mapping between conntrack entries and NATTYPE entries and a conntrack module can be configured to update a NATTYPE entry when a conntrack entry is updated and the conntrack entry includes a mapping to a NATTYPE entry. Alternatively, a hardware accelerator controller can be configured to refresh conntrack entries as well as NATTYPE entries.

Abstract: Apparatus and methods for efficient NAT and ALG processing is disclosed. An exemplary method includes the operations of deep scanning a packet received over a connection to determine an application level gateway (ALG) process to be performed on the packet, associating the connection with the ALG process, and forwarding additional packets received over the connection to receive the ALG process based on said associating so that deep scanning of the additional packets is bypassed. An exemplary apparatus includes a processor to deep scan a packet received over a connection to determine an ALG process to be performed on the packet, a database to associate the connection with the ALG process, and a packet transmitter to forward additional packets received over the connection to receive the ALG process based on said associating so that deep scanning of the additional packets is bypassed.
