Wide Area Network Services

Nearly all of the data transport in state government — including city, county and educational network traffic — is combined onto DIS’ managed Wide Area Network infrastructure. Gathering this much demand in one place means we can competitively acquire large amounts of bandwidth, driving down costs while boosting speed and capacity. Our aim is to help you focus on your core business, so we act as your single point of contact for designing, ordering, implementing and operating networks — dispatching staff around the clock to resolve problems and work with vendors.

The Campus Fiber Network

A high-speed fiber optic backbone service that interconnects voice, video and data communications for customers located in over 30 buildings on the state Capitol Campus in Olympia.

Advanced Transport Services (ATS)

ATS is a reliable and economical wide area network transport service provided over a secure Multi-Protocol Label Switching (MPLS) infrastructure. Customer sites are connected to DIS regional nodes sites. The nodes sites are located in Olympia, Lacey, Seattle, Vancouver, Yakima and Spokane. The nodes sites are connected together using high-speed SONET and Ethernet circuits from various service providers. ATS offers customers the security of a private IP network built on a shared, fault-tolerant, high-speed IP network infrastructure.

Interconnect Services

DIS designs, orders, implements and manages a complete package of vendor services and equipment that connects customer field offices to the nearest DIS node site. Combined with Advanced Transport Services, Interconnect Services provides customers a complete multi-access networking service with DIS acting as a single point of contact.

Internet Services

DIS provides state and local government customers with high speed, secured and unsecured Internet access. This service includes Domain Name services and IP addressing.

InterGovernmental Network (IGN) Services

The IGN is the common, standard Internet protocol-based data network used by DIS customers to connect to state agencies, counties, and cities with known end points, managed gateways, and applications. The IGN is an example of the State of Washington's enterprise architecture principle of commonality.

SGN

The State Government Network (SGN) is the common, standard Internet Protocol-based network to be used by state agencies to connect separate locations within and among those agencies.

Ethernet

A local-area network (LAN) architecture. Ethernet uses a bus or star topology and supports data transfer rates up to 1Gbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of the most widely implemented LAN standards.

Frame Relay

Frame relay is a data link network protocol designed to transfer data on Wide Area Networks (WANs). Frame relay works over fiber optic or ISDN lines. The protocol offers low latency and to reduce overhead, does not perform any error correction, which is instead handled by other components of the network. Frame relay has traditionally provided a cost-effective way for telecommunications to transmit data over long distances.

DSL

DSL technologies use sophisticated modulation schemes to pack data onto copper wires. They are sometimes referred to as last-mile technologies because they are used only for connections from a telephone switching station to an office, not between switching stations.
