Ticket Servers for Network Traffic Prioritization
Cory C. Beard1,3 and Victor S. Frost2
For broadband packet networks  ticket servers using an agent communication language;
then a ticket server intelligent agent determines how valuable of a ticket to issue. Use
of ticket servers and agent communication enables quick adaptation to dynamic context
changes and provides user feedback so that high priority communication activities can
be conducted effectively.
KEYWORDS: Priority; ticket servers; resource management; emergency management.

Modern broadband data networks are being designed to integrate all types of
multimedia traffic. More  with disaster response—that tremendous stress is
placed on these networks. In New York City, most notably the stress was on

This paper specifically addresses the issue of network resource availability
for NS/EP network communications. It is common in NS/EP contexts for the
availability of network resources to be severely restricted in the aftermath of a major
event [6–9]. In some cases,  to stay on the line until they could get information

workers to call the emergency command center when they received a page to come

Serving priority users in NS/EP situations involves providing a so-called
“emergency lane” for priority traffic [12] where important resource requests are

those of greater importance to network operators would be those which have
greater revenue-generating capability. During exceptional conditions like emergencies work proposes a mechanism for doing just that.
Traffic management mechanisms to preferentially handle priority traffic are being
developed elsewhere [13–16]; this work addresses how those priority flows are
first identified and authorized.

Exceptional conditions can occur suddenly and the context in which the network
would be operating would be highly dynamic. Effective administration of
priorities in such circumstances  be considered high priority—A simple
approach to administering priorities would be to assign static priorities
based on user identity. This would not be sufficient during a crisis, however.
Network resource allocation should more closely match the E-911

航空公司管理信息系统的设计摘要
一个正常营运的航空公司需要管理所拥有的飞机、航线的设置、客户的信息等，更重要的还要提供票务管理。面对各种不同种类的信息，需要合理的数据库结构来保存数据信息以及有效的程序结构支持各种数据操作的执行。
本设计讲述如何建立一个航空公司管理信息系统。一般而言，航空公司的管理信息系统应该包括人事、工资管理模块 。
1 系统设计
1.1 系统功能分析
系统开发的总体任务是实现各种信息的系统化、规范化和自动化。
系统功能分析是在系统开发的总体任务的基础上完成。本例子中的航空公司管理信息系统需要完成功能主要有：
l 舱位信息的输入和修改，包括舱位等级编号、舱位等级名称、提供的各种服务类别，以及备注信息等。
l 客机信息的输入、修改和查询，包括客机编号、客机型号、购买时间、服役时间、经济舱座位数量、公务舱座位数量、头等舱座位数量以及备注信息等。
l 航线信息的输入、修改和查询，包括航线编号、出发城市、到达城市、航班日期、出发时间、到达时间、客机编号、经济舱价格、公务舱价格、头等舱价格和备注信息等。
l 客户等级信息的输入、修改，包括客户等级编号、客户等级名称、折扣比例和备注信息等。
l 客户信息的输入、修改和查询，包括客户编号、客户姓名、客户性别、身份证号码、联系电话、客户类型和备注信息等。
l 订票信息的输入、查询和修改，包括订票编号、客户编号、客户姓名、客户类型、折扣比例、航线编号、出发城市、到达城市、出发时间、舱位类型、票价、结算金额和备注信息等。
1.2 系统功能模块设计
对上述各项功能进行集中、分块，按照结构化程序设计的要求，得到如图9-1所示的系统功能模块图。
