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.
