Sample job description
The network analyst will provide support for all networking equipment including voice, data, and video within the production environment. Support can include design, implementation, problem determination, resolution, and applying fixes to hardware and software. This includes the monitoring of all equipment and links to ensure the systems are functioning properly for information delivery including, but not limited to, routers, switches, firewalls, PBXs, and voicemail systems.
The network specialist also will test new network and communication products, interacting with vendors as needed while gaining an understanding of the products. The network specialist is expected to develop substantial understanding and knowledge of HBO**s network architecture, the application development architecture, and the Web architecture.
With only moderate supervision required, the network specialist will:
- Install, monitor, and maintain all hardware and software components related to the operation of HBO**s voice, video, and data network including system performance
- Monitor and assist less experienced team members with troubleshooting all network connections
- Monitor bandwidth use, analyze traffic patterns and volumes, and make recommendations to management on solutions for improvements
- Use monitoring tools, protocol analyzers, and cable testers to troubleshoot, diagnose, and identify failing/failed networking components. Conduct performance tuning and capacity planning for the existing network
- Design, code, and implement tools to aid in the support of the network environment
- Interact effectively with IT application groups in order to recommend the most effective and productive protocol configurations to work on the network
- Isolate and resolve network-related service calls and problems, and diagnose and correct problems resulting from component failure or normal use of the network
- Evaluate, test, and recommend hardware, software, and diagnostic tools
- Provide level two technical support to clients and all other IT technical groups
- Set up and support audio and video teleconferences and become familiar with the underlying technology
- As new devices and data circuits are added to our network, keep management and configuration tools current. Maintain network diagrams and ensure that they are updated and current
- Assist in creating disaster recovery test plans and participate in backup and recovery of systems and databases
- Review and take action on security notifications, either from our security group, vendor, or management on any vulnerability found on our production networking components
- Provide 24/7 support on a rotating basis as required by the needs of the organization. Some night/weekend coverage required
- Participate in the design and implementation of complex network architectures
- Periodically review network documentation to ensure both accuracy and completeness
- Bachelor's degree or equivalent work experience
- CCNP-level experience or equivalent experience required
- Familiarity with VoIP and TDM phone systems
- Excellent writing and verbal communications skills

Applications of Networks
Second course in telecommunications and networks. Network architecture, protocols, performance, design, and analysis based on application needs, organizational requirements, user requirements, and performance objectives
Network security and cryptographic protocols. Network vulnerabilities, attacks on TCP/IP, network monitoring, security at the link, network and transport layers. Cryptography, e.g., secret and public key schemes, message authentication codes and key management. WLAN security, IPSec, SSL, and VPNs. E-mail security (PGP, S/MIME), Kerberos, X.509 certificates, AAA and Mobile IP, SNMP security, firewalls, filters, and gateways. Policies and implementation of firewall policies, stateful firewalls, and firewall appliances. Network-related physical security, risk management and disaster recovery/contingency planning issues and housekeeping procedures.
Application Development for Mobile Devices
Focus on information system applications that run on top of wireless infrastructure such as multimedia messaging, mobile inventory control, location aware services including wireless technologies (GSM, CDMA2000, UMTS, 802.11, Bluetooth), mobile information systems and applications (M-Business, location-based services, wireless CRN), wireless information system challenges and architectures (security, reliability, mobility, power conservation, gateways, proxies), mobile application protocols (SMS, EMS, MMS, WAP), thin and thick client mobile application development (WML, VXML, Java, J2ME, J2EE, .NETCF, C#), and business case studies of mobile applications.
Introduction to Wireless Networks (Cross listed with TELCOM 2700)
Introductory broad overview for students with a basic background in telecommunications. Not for telecom majors. Principles of wireless communications and how they differ from wired communications. Fundamental concepts including transmission and mitigation techniques (e.g., modulation and coding, propagation, interference, and antennas) for wireless systems, multiplexing techniques, wireless system architectures, mobility management, security, protocols, and location technology. Systems include cellular phone networks (e.g., cdma2000, UMTS), wireless local area networks (e.g., IEEE 802.11g), personal area networks (e.g., Bluetooth), fixed-point broadband wireless (e.g., WiMAX) and satellite systems.
