  6. 6. Jeffrey J. Sicuranza page 6 based QoS tool set to facilitate testing, deployment and support of QoS commands and protocols for the network support staff was developed. This document was an all encompassing, strategy, plan and “how to” guide to assist ConEd in deploying and managing QoS across its enterprise network to support a call center disaster recovery VoIP based system and upcoming enterprise wide VoIP and Video deployments. • Was hired by ConEd’s legal department during last minute subsidiary sale negotiations to provide industry based subject matter expert opinion, facts and research for ConEd regarding Metro Ethernet, MPLS and MST technologies to help ConEd make a decision regarding a multimillion dollar Metero Ethernet carrier subsidiary transaction. Conducted research, held interviews and provided the legal representatives facts and testimonial regarding Metro Ethernet business trends, technology and case studies. Attended several high level meetings with CEOs, and legal representatives from all interested parties to present and provide research findings and testimonial on such technologies and industry trends. This information was critical to ConEd to render a decision and direction in regards to a pending subsidiary sale transaction. • Upgrade enterprise headquarters’ Catalyst 6500 based core backbone from Supervisor II to Supervisor 720 modules and convert configuration from Hybrid to Native. My role was project manager and engineer for entire project. This project was required to position the enterprise core to utilize new fabric enabled SFP based line cards for additional port density, enhance server farm support, provide IOS based feature consistency and advance features such as QoS, security, MPLS, plus use of fabric enable modules and advanced fabric switching modes for increased stability and throughput. Selected hardware, upgraded fans, reviewed current and new line card power and firmware revisions to ensure all modules worked together with the new supervisor and IOS combination. Manually converted backbone software configuration from Hybrid “set” command line port based to IOS interface based and resolved cross core switch and various different redundant access layer switch, Etherchannel, Trunk, Spanning-Tree Protocol, HSRP, Vlan related negotiation and configuration issues resulting from different access layer switch platforms with different versions connecting to a new IOS based core.. Identify all cross core switch and router uplink EIGRP neighbor relationships and plan for expected EIGRP neighbor, convergence and routing state changes during the phases of the upgrade. All configurations were developed and tested on a similar core switch in a lab and checked for accuracy before deployment. Pre and post upgrade state diagrams were created to provide support staff easier planning and troubleshooting references. A detailed migration and multi scenario roll-back procedure was drafted, rehearsed with all support groups to ensure a transparent upgrade was completed successfully according to schedules ratified by management. This upgrade work entailed a physical migration of supervisor modules, some line card restacking and minor cable changes independent of each core switch with no impact to the business operation. A physical operational flip state from one supervisor model to the other of each switch was used to mitigate impact to the network and user community. A final disaster recovery test of both switches was also conducted to determine how the IOS based Core will behave in the event of a switch failure. This test provided critical information on the behavior of the core and for the network support staff to reference regarding how network management, routing protocol, core switch and floor recovery actually behave if a real issue arises. • Provide support for enterprise wide DWDM optical MANs. Identify any issues with Dynamic Packet Transport and 802.17 Resilient Packet Rings(RPR) and Spatial Reuse Protocol(SRP). Identify SRP neighbor wrapping status and wrapping sequence to

Tested EIGRP Bidirectional Fail Over(BFD) to determine if feature is applicable for use on the DPT routers and upgraded Catalyst core switches. • Provide in-depth hands on consulting and mentoring to engineers responsible for the upgrade of a major electric control Supervisory Control and Data Acquisition(SCADA) network. Provide network upgrade architecture guidelines and migration approaches. Outlined issues of simplifying the network from a static routed, with RIP and NAT Frame- Relay based network experiencing stability and configuration management issues to a simpler more secure, scalable and dynamic network using, HSRP, EIGRP and IPSec. Also outlined the issues and approaches on how to migrate a live IP based SCADA network from one architecture to another with no impact to the Electric Operations control centers. Identify critical application issues and behavior relating to the timing impact of electrical grid control and polling processing packets relying on Dynamic Network Protocol functions running over TCP/IP. Identify several application level bugs relating to the TCP stack handling of DNP on GE’s DMS 200 Master Terminal Units(MTU) it’s Ethernet, TCP/IP stack and redundancy limitations and bugs and corresponding Remote Terminal Units(RTU). Ensured the migration covered what exactly is an application layer issue and what is a network layer issue and what issue type causes what response so critical control center personnel know exactly what to expect on the SCADA system if any of the network components between MTUs and RTUs on the IP network fail. Identify and document packet level decodes of the application and network’s use of DNP 3.0 protocol and TCP. Trained engineer on how to capture DNP packets and what to look for when symptoms suggest an application issue. Suggested the use of DNP simulation software for the SCADA lab so future DNP testing over an TCP/IP and Cisco based network can be accomplished without the initial need for an expensive RTU, master station and trained SCADA personnel to be present in the lab. • Developed a low cost distributed protocol analysis solution to save the ConEd almost half a million dollars that would have been spent on a commercial solution. This solution consisted of shareware analyze software, Windows terminal server or VNC for remote control and using existing company assets for the remote network connectivity pods. Created a web based portal page so network support staff, via a browser can access any remote analyzer anywhere in the enterprise. The analyzers had from one to multiple 10/100/1000 Ethernet adapters and were connected to multiple switches. The analyzers were initially deployed in a pilot program to strategic locations in the enterprise. The use of Ethereal and Packetyzer provided ConEd the tools to obtain detailed traces of application issues, conduct basic VoIP RTP jitter analysis and monitor the network for security issues. The saved trace files can also be uploaded to the company’s licensed Sniffer applications. This pilot proved that the network support staff can have low cost, easy to manage and scale distributed protocol analysis solution without spending hundreds of thousands of dollars on a commercial system which would have had only 10% of its capabilities used. • Provide day to day high level support of the network infrastructure and routing protocols.

Some of the projects completed for clients are listed below. Clientele is listed on company website. • Piloted a Point to Point(PtP) Coarse Wave Division Multiplexing (CWDM) optical solution for a case study on CWDM and 802.1w Rapid Spanning Tree protocol. This solution entailed utilizing Cisco midrange catalyst switches, 1530nm CWDM Gbics and 40dBm tunable Variable Optical Attenuators(VOA). The study’s goal was to provide a simple scalable way to use a single/dual strand of single mode fiber and scale the link’s capabilities using less expensive CWDM technologies. The use of Rapid Spanning- Tree(RST) and Multiple Spanning-Tree(MST) protocols to achieve improved link resiliency was applied. An optical budget analysis was performed, integration and tuning of the VOA to prevent laser burnout for the shorter distance, and the configuration of 802.1w/s was added to the Catalyst switches. By using the CWDM Gbic modules and single mode fiber the solution is scaleable from an initial 1.2gbs 802.3z PtP campus link to 8Gbs Ethernet or over 40Gbs using 8 to 16 lambdas with the addition of passive OADMs and additional CWDM Gbics on existing or future switches. The case study proved that for clients with existing single mode or dispersion shifted fiber in place, longer, non amplified, PtP distances between buildings is achievable economically by using a scalable solution utilizing any of the three optical bands S,C and L that can be built with just a pair of CWDM modules and as apposed to a more expensive typical WAN, Metro Ethernet or DWDM solution. • Completed a Wireless ISP (WISP) venture research project. This project determined whether it is feasible, economically and technically, to provide last mile internet and free SIP based voice services to a selected demographic market in the NY region. The first phase of this project was to conduct a technical proof of concept. This phase tested the concept of basic WISP functionality, RF behavior, VoIP over wireless, security and billing. This phase provided answers to the practical and economical use of current commercial and consumer grade wireless technologies by conducting a set of proof of concept tests. These tests were comprised of building out various single or multi cell WISP sites and testing many types of applications, especially VoIP, over wireless utilizing advancements in SIP based products. Developed the project plans, wireless cell, application testing matrixes and roam criteria for the project. Created the RF cell engineering/planning documentation, traffic generation criteria for distribution system and the cells. Conducted physical and RF site surveys of single omni and sector cells for roaming tests. Built a temporary and portable mast system to host the appropriate antennas. Testing includes omni directional and sector based high gain antennas from MaxRad and Hyperlink for cell coverage in a residential area. 802.11b and g cells in separate and mixed configurations were tested. Proxim and Asus access points were used for initial testing with possible others from Cisco, Motorola, Trango, Meru, Aruba, YDI et. al. to follow. Testing of multiple call and data services on the cell was conducted and monitored with wireless and wire line
  9. 9. Jeffrey J. Sicuranza page 9 protocol analyzers and network management tools. Distribution System comprised of Cisco Catalyst switches utilizing QoS policies created for SIP traffic using Cisco’s NBAR technology to classify traffic. DSCP and Assured/Expedited forwarding markings were applied to SIP traffic. Selection of SIP based products such as SJlabs, Xten, Skype and PcPhoneline Soft phones on laptops and PDAs(thus turning the PDA into a WIFI phone). Interactive Intelligence SIP server and Brekeke OnDo SIP servers were evaluated for proxy and redirecting services. Testing of sending and receiving SIP based calls from the wireless cell to POTS was conducted at various traffic levels on the cell and distribution system. Skype and Freeworld Dialup services were also tested over the wireless cell. The results of such testing was included into a report that shall outline the feasibility and behavioral aspects of wireless last mile access as well as the mechanics of SIP based VoIP. This report provided vital information for the follow on phases of the project and the overall business plan. • Conducted wireless networking security audits for several NYC based clients. The wireless security audits consisted of scanning for rogue or incorrectly configured access- points, WEP vulnerabilities, radio frequency leakage issues and backdoor access into the enterprises via wireless portals. The reports outlined the types of attacks to expect such as War Drivers, WEP cracking, wireless sniffing, virus launching points, open access to the internet via the enterprise and wireless jamming. The audits outlined all weaknesses regarding the enterprise’s wireless infrastructure and its security vulnerabilities to the internal wired infrastructure. Recommendations included reducing RF signal propagation, SSID and Beacon management, VPN usage, WEP key rotation, Open and Shared Key access point association and authentication methods. Protocols such as 802.1x and 802.11i, as well as infrastructure component features including MAC address and upper layer packet filtering, centralized user and key authentication systems plus wireless scanning and intrusion detection tools were also reviewed. The audit’s recommendations also covered relevant wireless addendums to corporate security policies in place. A variety of Wireless enumeration, RF analysis and protocol analyzer tools were used. Some of the tools used to conduct the audits and recommended to clients were as follows: Netstumbler, AirSnort, Wepcrack, Kismet, Airmagnet, Packetyzer/RF Protect remote 802.11a/b/g sniffer, Linkferret 802.11b/g sniffer, Nsspyglass, Airsnare and Boson’s Getpass, a Cisco router password cracker. One of the audits helped secure a major NYC utility’s wireless network from becoming a potential terrorist attack target. • Designed and implemented a custom, low cost, highly functional, license free, 802.11b based wireless Point to Point(PtP) solution. The solution provided network access and basic Microsoft Netmeeting plus VoIP capabilities between a client’s two campus based corporate headquarter office buildings that were almost a mile apart. The solution consisted of custom made wireless routers using existing server hardware, Windows 2000 Server operating system with RAS, Orinoco 802.11b wireless radio adapters, off the shelf and custom made directional Yagi and Andrews Parabolic antennas. The solution provided up to 11mbs of secure bandwidth between the buildings for network connectivity and back office application access plus the use of Microsoft Netmeeting and VoIP between Cisco 2620s at each site with FXS interfaces and standard POTS handsets. The wireless segment is router and not bridged based thus utilizing static routes and minimizing inter building broadcast traffic. OSPF is also available for this solution when future growth requires it. The solution enabled help desk support personnel to stay connected at each building without the cumulative toll costs. A full RF analysis that covered reviewing RF operational theory, Fresnal Zone, LOS, free space LOS, diffraction, refraction, VSWR, EIRP, signal strength and traffic analysis was conducted. Antenna gain analysis and intentional radiator calculations were used to identify the most efficient gain in dBm and dBi for antenna selection and transmission circuits, which used LMR-400 cables and TNC N connectors.
  10. 10. Jeffrey J. Sicuranza page 10 The use of Orinoco and Cisco wireless radios and utilities plus Aerocomm’s SA3000 2.4Ghz Spectrum Analyzer and the Linkferret 802.11b protocol analyzer were used to determine radio interference, signal strength and protocol/traffic efficiency. Basic QoS services, such as QoS packet scheduler and RSVP are available for the VoIP traffic when required. Windows Terminal Server and VNC were used for remote management of the wireless routers. Digital Matrix’s AirSnare shareware Wireless IDS software was installed on the wireless routers and configured for email notification of any rogue radio access activity. This solution provided a lower cost and an immediate ROI compared to other solutions from Cisco’s Aironet or Proxim’s Orinoco/Tsunami product lines which were also considered for this project. The increased savings from not running fiber or using telecomm T-1/T-3 links between the buildings were immediately realized. The solution also provided an easy upgrade path from 802.11b to 802.11a or g technologies for additional link segment bandwidth by just swapping the wireless radio cards out of the Windows server based wireless routers and changing or adjusting the antennas. • Participated in the beta programs for two 802.11 based wireless protocol analyzer manufactures. Provided and applied my experience of over 12 years of protocol analysis and protocol analyzer experience to product testing and functionality. I provided critical functional feed back for Baseband Technologies Linkferret 802.11b protocol analyzer and Network Chemistry’s Packetyzer/WSP100 remote 802.11b analyzer. I provided operational and GUI feedback and suggestions, which have been implemented in enhanced versions of the products. My input was based on extensive protocol analyzer experience from NAI and Agilent and contributed to the ongoing enhancement of these newer products. Some suggestions included enhanced upper layer protocol brief displays, simpler packet filtering and traffic generation interfaces, RF signal discrepancies, AP enumeration, WEP decoding, OUI decoding, host tables, protocol colorization and ASCII packet searching and go to features. I also conducted in-depth testing of the products to determine enterprise level functionality. Documented all results and participated in product improvement sessions with developers. Identified improper protocol operation with the TZSP protocol used by the WSP100 remote 802.11b sensor. My early assistance with the Packetyzer/RF Protect beta program helped the product to mature until it was re-licensed by Wildpackets as the new RFGrabber product.
