The Dept. of Info Svcs is tasked to design and deploy a state wide 10 Gigabit SONET Ring to increase WAN transport capacity beyond the current 100 Meg Ethernet circuits interconnecting three large WAN aggregation node sites. Our WAN aggregation sites serves between 100 and 400 T-1 connections to remote office routers managed by DIS. The objective of the project is the installation of a 10 gigabit SONET ring to improve throughput from remote sites into core network infrastructure in Olympia as well as consolidating TDM transport onto our internal infrastructure. Key deliverables are to acquire hardware, implement fault tolerant SONET rings, design and adopt a transport layer quality of service between node sites, install high capacity Ethernet cards in our Catalyst 6500s, and redesign our OSPF and M-BGP (MPLS) network to utilize the new transport service. The project was a success
DIS identified a requirement to install an intrusion detection service (IDS) on the internet border to monitor and protect internal and external servers from network attacks. The objective is to install multiple devices in a manner that eliminates network delays while monitoring critical servers. The deliverables were to design, purchase, and install the devices without impacting the service offering. The project failed. The devices we purchased were incompatible with our network design and infrastructure. The project failed. The project failed due to lack of change control mechanisms and a lack of an ongoing Plan Do Check Act process. These processes were later adopted.
DIS must transform it's DR site from a simple T-3 connection into a state mainframe service in Philadelphia to a model supporting full MPLS node site connecting to multiple customer owned mainframe connections in Philadelphia. The new MPLS connection would use MPLS virtual routing and forwarding tables. The objectives are implementation of MPLS at the DR site, reprovisioning the DS3 as an MPLS Transport Circuit, and to support MPLS connections from customer mainframes. Deliverables include, a turn-key MPLS DR site, training NCC staff to bring the DR site on line, a firewall, and customer connections at the DR site. The project was designed and implemented successfully.
DIS offers VPN services using the common transport network. High risk customers require VPN tunnels into their MPLS VPN. The objective is to design a network connection into the VPN service infrastructure dedicated to tunnels into the customer's network. The deliverables are install redundant VPN firewalls and MPLS routers, and to migrate existing VPN customers onto the new service. The design was developed, tested, and migration strategies were accepted. The project was successful.
DIS's route reflectors are at end of life must be replaced. The objective of the project is to identify and procure a router platform capable of supporting route reflection for the statewide MPLS network, install the devices, and migrate route calculation onto them without service disruption. Key deliverables include transitioning the route reflector responsibilities onto the new platform without impacting network performance or network up time. The project was difficult to sell. The project was implemented successfully.
DIS is required to upgrade the core transport network to 10 gigabit Ethernet in support of future projects that will add a 40 gigabit DWDM metro Ethernet service to the DIS WAN/MAN transport service. The objectives are to procure 10 Gigabit modules for four service provider class Catalyst 6509 routers, then redesign the routing and switching to support the 10 gigabit service. Key deliverables are: upgrade power supplies on four 6500 switches, consolidate Ethernet modules to make room for and install the 10gig Ethernet modules, then enable 10 gig within the core. The project was delayed several weeks in cooperation with a customer request. The project was successful
DIS purchases two CRS-1 routers to support seven Ten Gigabit Ethernet connections to our new DWDM Rings. The CRS operates in a manner unlike that of Cisco 7500 and 6500 routers. The CRS was required to link into the Datacenter Core at 10 Gig. The project required an MPLS, BGP, and OSPF design compatible as well as supportable on the current network topology. Project Risks included operating a new devices with an IOS unlike other devices on the network. The current operational staff had no experience on the new device. The project was successfully implemented.
DIS is required to install two Nexus 7000 service provider class switching units and four Nexus 5000 distribution layer devices into the DIS core datacenter network. The Nexus will connect using 10 gigabit Ethernet. Project deliverables were installation of the network devices to include fiber optics, VLAN design, layer-3 routing design, layer-4 BGP design. Risks include dynamic recalculation of the layer-2 root for all VLANs onto the Nexus and spanning-tree loops that couldn't be resolved dynamically. Some risks that were not identified during project planning. Layer-3 chose to use the Nexus as the primary transport path through the MPLS network. The Nexus was not configured to use MPLS as a transport protocol. This omission allowed forwarding of packets without the necessary MPLS packet headers. The root cause was found during post analysis of the packet forwarding problem was the default OSPF bandwidth value for the nexus is 40Gig. The standard bandwidth values is 100Meg. The Nexus was configured for a bandwidth value identical to other devices on the network as well as the inclusion of the MPLS protocol.

DIS operates four node sites with Cisco 7513 routers carrying our MPLS transport traffic. The 7513s must be replaced. The objective of the project is to identify a service platform suitable to replace the 7513s. The deliverables are procurement, test, and installation the devices at the node sites. The project encountered two delays. One delay was in response to customer requests, the other to a product failure. The time line was extended 45 days to meet scheduling rules. The project was successful after the hardware was repaired.
DIS is required to design and install a metro Ethernet service across 3 towns in the Olympia area. The objective implement a one gigabit Ethernet service to 140 to 160 state customers in the metro area. Key deliverables are an RFP, a network design, procurement and installation of equipment, and operational support of the new network. The project stalled due to budget constraints and conflicting priorities. The project objectives and deliverables were later overhauled and the project was reinitiated.
DIS is required to design and install a 40 gigabit Metro Ethernet service to support 140 to 160 state customers in the local metro area. Key deliverables are procurement and installation of 14 Cisco DWDM devices and two CRS routers, provision 6 lambda rings, test the service stability and fail over capabilities, acceptance of the network by operations, and to deliver the service to Olympia area customers. The project is on tract and successful.
