Abstract

A computer system may include at least one client computing device, and a plurality of host computing devices each configured to provide virtual computing sessions for the at least one client computing device. Each host computing device may have a virtual delivery agent (VDA) associated therewith configured to connect the at least one client computing device with the virtual computing sessions. The at least one client computing device may be configured to request virtual computing sessions from the VDAs in accordance with an ordered list of the VDAs. The VDAs may be configured to re-direct new session requests from the at least one client computing device to a lower VDA in the ordered list when an existing virtual computing session is already active with the host computing device associated with the lower VDA.

Claims20

Dependent claims

A computer system comprising:

a plurality of client computing devices;
and
a plurality of virtual delivery agents (VDAs) configured to connect the client computing devices with virtual computing sessions provided by a plurality of host computing devices;
wherein the client computing devices are configured to request virtual computing sessions from the VDAs using respective connection leases including an ordered list of VDAs, and when requesting a new virtual computing session, each client computing device sending a new session request to a first VDA in the ordered list of its connection lease and, if unable to connect to a virtual computing session through the first VDA, continuing to request a new session from each of the remaining VDAs in the list in descending order until receiving a connection with a new virtual computing session;
wherein the VDAs are configured to re-direct new session requests from the client computing devices to a lower VDA in the ordered list when existing virtual computing sessions for the client computing devices are already active with the host computing device associated with the lower VDA;
wherein at least some of the client computing devices have different ordered lists of VDAs.
