Abstract: This disclosure is directed to techniques for supporting transition between network communication protocols in a communication network. The techniques may be applicable to different network communication protocols, but are especially useful in the transition from the IPv4 communication protocol to the IPv6 communication protocol in a wireless communication network. In general, to reduce consumption of scarce IPv4 address during the transition period, a network communication device implementing a dual IPv4/IPv6 stack acquires an IPv4 address only when necessary to communicate with IPv4 resources on the network. The network communication device uses an IPv6 address at the start of a communication session, and does not acquire an IPv4 address unless a need arises later in the session for communication with an IPv4 resource. The IPv4 address may be acquired for a limited period of time, such as fixed period of time or a period of actual usage, to further promote availability of IPv4 addresses.

Abstract: A system and method are disclosed for increasing the efficiency with which data is transmitted over a network link. Voice packets are encoded to include header bits that indicate the presence and duration of pauses in the voice transmission. A Network linking device monitors incoming voice packets on a link, checking for the presence of a pause. The linking device also keeps track of all voice connections on the link. When none of the voice connections are active, the linking device increases the size of the maximum allowed transferable unit (MATU), thus fragmenting less data packets than it would have fragmented if a voice connection had been active. Fragmentation is reduced while maintaining sound quality.
