Abstract

A system for service mobility management, and service placement is proposed. The system takes into account various factors such as the mobility of the user, the congestion / link constraints in network paths, computing and storage capabilities available at intermediate nodes, and impact to end-to-end latency/bandwidth based on service placement. This results in a smarter placement of the service that meets the requirements for the service. A service mobility management node is proposed to determine anchor points to provide service, and a selection of the anchor point to provide service dynamically. Learning the needs and behaviors of users can also help the SMM node deliver content smartly. More than one anchor point could be used for such service, and information may be delivered to more than one user platform. Finally, all the functions associated with the user or the network or the service can be executing in virtual machines interacting with each other to coordinate information exchange. Virtual machines at the SMM node, anchor point nodes, user platforms, and in the cloud could all coordinate with each other to orchestrate information exchange.

Service, mobility, and data management based on mobility , networking, and computing/storage constraints and the use of interacting user /network/cloud VM functions for such information management

Emerging service architectures promote computing and services capabilities at the edge of a network. This allows reuse of content at the edge by multiple users avoiding repeated transport of the content for multiple users. Latency associated with content being placed closer to the user is reduced by placing at the edge, and congestion issues in network paths can be minimized. However, it is possible that placing the service/content at the edge of the network, or placing it solely in the cloud, may not always the best option. This work explores alternative options for such service placement.

A cloud service extends itself into a network with various anchor points for the service in the network. The anchor points are expected to be reachable over IP. In general, it is desirable to push the content as far to the edge as possible such as to an LTE ENodeB or an RNC or a NodeB in the RAN, or a WiFi Access point, for the best possible service, avoiding congested network paths and delays. However, for highly mobile users, this can result in repeated handoffs, resulting in repeated migration of the service. Such frequent service migration at short time scales for highly mobile users can result in lost packets, and impact overall performance and user experience. For users that are highly mobile, an anchor point is selected that is higher up in the network hierarchy that addresses the mobility such as at an S-GW or a P-GW in LTE core networks, or at an SGSN or GGSN in 3gpp core networks. This can reduce the need to migrate the service as the user moves. An anchor point that is selected purely based on...
