摘要： To control concurrent access problems, the job ticket service may employ branch locking features, that is, the capability to lock a job ticket at the branch level. The branch locking may be accomplished by one of several methods. The work flow controller may assign one or more specific processors to perform the tasks identified with the branch to be locked. Where more than one processor is authorized access to the same branch, the job ticket service may lock the branch when one of the authorized processors actually acquire the branch. The job ticket service may lock the branches by setting a lock/unlock flag for each branch. Processors accessing the job ticket may then review the lock/unlock flag status to determine if the branch may be accessed. In some circumstances, the job ticket service may allow access only to those branches that are unlocked. A processor that has completed a task defined by the branch may need to have the branch unlocked in order to modify the branch.

摘要： A bidding service may be used to receive bid information to complete a job request, from processors coupled to a job ticket service center. The processors submit bids in response to posting of job ticket notices at the service center. A work flow controller may post the job ticket notices after receipt of the job request. The job ticket notice may include specific tasks or branches that must be completed to complete the job request. The job ticket notice may include descriptions of specific branches and their interrelationships in sufficient detail to allow the processors to bid for completion of the branches. The bidding service may select bids from the processors based on set criteria. For example, the job request may specify minimum performance requirements (e.g., a maximum cost and a completion deadline). The bidding service may reject any bids that fail to satisfy the minimum performance requirements. Where the work flow controller has established multiple branches, each such branch may include minimum performance requirements. The branch-specific performance requirements may be established by the work flow controller based on overall performance requirements for the job ticket.
摘要翻译：投标服务可用于接收投标信息，以完成作业请求，从加工到工作单服务中心的处理器。处理器在服务中心发送工作单通知时提交投标。工作流程控制器可以在接收到作业请求之后发布作业通知。作业单通知可能包括完成作业请求必须完成的特定任务或分支。工作单通知可能包括具体分支的描述及其相互关系，以便处理者能够投标完成分支机构。投标服务可以根据设置标准从处理器中选择出价。例如，作业请求可以指定最低性能要求（例如，最大成本和完成期限）。投标服务可以拒绝任何不符合最低性能要求的投标。在工作流程控制器已建立多个分支的情况下，每个这样的分支可以包括最低性能要求。分支特定的性能要求可以由工作流程控制器基于作业单的总体性能要求来建立。

摘要： A job ticket service center includes features to provide security and to control access to a job ticket and related resources. The service center may include programming or servers to authenticate a processor and to authorize the processor to access a particular job ticket. An authentication server receives authentication information from a processor and an authorization server uses the information to check authorization functionality. The authorization or access rights of the processor may be carried as a part of the job ticket. Using these features, the service center may provide trusted authentication information about the processor to the authorization server, and the authorization server then performs its authority check functions. The job ticket maybe signed with an industry standard public key encryption message digest (MD) signature, and may be protected by a public key encryption system. Hence, any entity that has the public key may validate the job ticket without having to communicate with the authentication server. These features reduce communication between distributed server applications. The features also allow the job ticket to be passed from one processor to another processor, maintaining security, without communicating with the service center.
