IntroductionA brand new central hospital facility is to be built in western Pennsylvania replacing a current regional hospital. As a consulting firm, we have been asked to help in developing a strategic plan to utilize networks and other telecommunications resources to integrate the health delivery process for the hospitals community. The new hospital which covers about 200,000 square feet has 3 floors with 300 licensed beds, a 60 nursery and NICU, a level III ICU and CCU for up to 36 patients, a staff of 1200.

BackgroundThe current hospital serve a seven-county area in north central PA with a population of almost 200,000.The local community is fortunate to have ample fiber that reach 75% of facilities and service providers, including their new facility. 20 % of the remaining providers are served either by DSL, able modem, or P-to-P data services.

The remaining 5% are served by wireless services.

Network Topology

Network Design ElementsThe network design for the new [Regional Hospital] is based on the specifications provided during the initial discovery phase. A strong emphasis has been placed on the ability for all network components to support the current state of the art in healthcare information technology while also providing a flexible platform to extend those capabilities in the future.

Border Network and ConnectivityInternet Connectivity: I. Redundant Internet connectivity is important for the proper functioning of clinical operations. Redundant Internet connectivity is important for the proper functioning of clinical operations. Border Security: Security of the Internet edge will be accomplished using a two layer firewall design with Cisco 5585s at the first level and Palo Alto Networks PA-5050s providing second level filtering and higher layer protection. Both firewalls will be provisioned in an Active/Passive configuration. Wan Connectivity: Per the specifications provided WAN connectivity options for sites using fiber, DSL/cable modem, high speed point to point and wireless links are included in the design. of numerous aspects II. of numerous aspects

Core NetworkI. As in any network design the core network for the hospital network will act as the Nexus for all other components and their intercommunications. This place at the center of the network makes it imperative that we engineer in as high a degree of reliability as possible. To achieve this goal we will implement the core network as a pair of Cisco 6509E chassiss configured as a single Virtual Switching System.

III.IV.

These core switches will provide both L2 and L3 services to the other components of the network.Physical connectivity will be provisioned using 10 Gigabit SFP+ and copper 10/100/1000 line cards.

Datacenter NetworkI. For a greenfield datacenter design it is important to account for the increasing dominance of virtualization technologies, such as VMWare vCenter and Microsoft Hyper-V, and the use of large scale IP protocol storage systems from vendors such as NetApp and EMC. From a network design standpoint these trends point towards a need for fewer, higher bandwidth, highly reliable connections. This design is based on those goals. The datacenter network design is based on an aggressive transition to 10 Gigabit Ethernet connectivity for most hosts.

II.

III.

Access NetworkI. The access network portion of a hospital needs to support 24x7 operations in a highly available manner. Disruptions to service can have direct impacts on the quality of patient care delivered. To support this design goal the access network will be deployed in a more highly available manner than would normally be the case.

II.

III. To support the specified number of ports, described in the summary below, each floor of the hospital will have two IDFs.

Wireless NetworkI. Wireless medical devices, such as IV pumps, portable X-rays and ultrasounds, are an increasingly critical part of part of patient care.To support these patient care applications we will use of a rule of thumb of one access point per every 1200 sq ft of floor space.

II.

III. To support these patient care applications we will use of a rule of thumb of one access point per every 1200 sq ft of floor space.

Voice NetworkI. Voice Over IP provides the main source of communication in this proposed unified communications solution employing the Cisco Business Edition 6000 at its core. This system provides voice, unified messaging, mobility, contact agent center support and video conferencing capabilities.

II.

III. Voice service will be provided by a combination t1 links and SIP trunks using the two internet connections.

Implementation Timeline

ConclusionA strong emphasis has been placed on the ability for all network components to support the current state of the art in healthcare information technology while also providing a flexible platform to extend those capabilities in the future. We considered and respected all healthcare and privacy related legislation. We have placed particular concentration on security and integrity of information moving throughout the system.
