Abstract :
The cellular packet switch (CPS) is a distributed packet switch proposed for third generation wireless information networks. The infrastructure consists of an IEEE 802.6 Metropolitan Area Networks (MAN) linking base stations, databases, public switches and a cellular controller. Connectivity between MANs is via gateways. The paper addresses issues associated with movement between MANs. Inter-MAN handovers which do not involve the public switched network appear seamless. However, multiple inter-MAN handovers may produce an inefficient information flow among the MANs. The paper discusses the role of gateways in inter-MAN handovers, and path optimization procedures that generate more efficient paths. The path optimization procedures are evaluated based on the following performance criteria: guarantee of sequential delivery, avoidance of multiple copies and delay
