Methods and systems for implementing independent time in a hosted operating environment are disclosed. The hosted, or guest, operating environment, can be seeded with a guest time value by a guest operating environment manager that maintains a time delta between a host clock time and an enterprise time. The guest operating environment can subsequently manage its guest clock from the guest time value. If the guest operating environment is halted, the guest operating environment manager can manage correspondence between the host clock time and the enterprise time by periodically assessing divergence between actual and expected values of the host clock time.

Mechanism for implementing independent time in a hosted operating environment

A high speed data communications method and system is provided whereby multiple groups of software interfaces are used to link a Distributed Systems Services Unit to a Network Provider which connects to an Input/Output Interface Module which relates to external interfaces of a Network. The interfaces permit the capability of buffer sharing and lock pool sharing, in addition to improved Connection Library Element Interfaces which reduce the overhead that was previously required and further enables faster data transfer operations with reduced latency.

Multiple interface data communication system and method utilizing

An Output Interface function for a Cooperative Service Interface which allows export of data from a Distributed System Services unit (DSS) to a Network Provider unit (NP) whereby lock pools are shared as well as buffer pools in each unit. Copying of exported data from said DSS to said NP is eliminated by use of an image buffer pool in said Network Provider (NP) (Which holds pointers to data in memory) and which can export the data to an external I/O port.

Output interface method and system for enhanced data transfers via

An Input Interface functions for a Cooperative Service Interface unit and enables data from a network to be placed in a designated input buffer of a Network Provider (NP) which can convey pointers to a Distributed System Service (DSS) unit's image buffer pool for access of the data by said DSS from memory. Sharing of buffer pools and lock pools lessen the overhead and latency which would normally burden such data transfers.
