Computer Networking

A computer network or data network is a telecommunications network that allows computers to exchange data. The connections (network links) between networked computing devices (network nodes) are established using either cable media or wireless media. The best-known computer network is the Internet.

Network devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as servers and personal computers, as well as networking hardware. Two devices are said to be networked when a process in one device is able to exchange information with a process in another device.

TTS designs network topology. Network topology is the layout or organizational hierarchy of interconnected nodes of a computer network.

Network Switches
  • Unmanaged Switches:

    These switches have no configuration interface or options. They are plug_and_play. They are typically the least expensive switches, and therefore often used in a small office/home office environment. Unmanaged switches can be desktop or rack mounted.
  • Managed Switches:

    These switches have one or more methods to modify the operation of the switch. Common management methods include: a command-line interface (CLI) accessed via serial console, telnet or Secure Shell, an embedded Simple Network Management Protocol (SNMP) agent allowing management from a remote console or management station, or a web interface for management from a web browser.
  • Smart (or intelligent) Switches:

    These are managed switches with a limited set of management features. Likewise "web-managed" switches are switches which fall into a market niche between unmanaged and managed.
  • Enterprise Managed (or fully managed) Switches:

    These have a full set of management features, including CLI, SNMP agent, and web interface. They may have additional features to manipulate configurations, such as the ability to display, modify, backup and restore configurations. Compared with smart switches, enterprise switches have more features that can be customized or optimized, and are generally more expensive than smart switches. Enterprise switches are typically found in networks with larger number of switches and connections, where centralized management is a significant savings in administrative time and effort. A stackable switch is a version of enterprise-managed switch

A router is a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks. When a data packet comes in one of the lines, the router reads the address information in the packet to determine its ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. Routers perform the "traffic directing" functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node. The most familiar type of routers are home and small office routers that simply pass data, such as web pages, email, IM, and videos between the home computers and the Internet.

  • Fast, easy and secure access to schedules, client/patient, clinical and financial information from any Web-enabled PC or wireless device with remote management functionality and encrypted security controls.
  • Low bandwidth connection requirements with an ultra-thin client/server application that can support hundreds of users.
  • Moderate system requirements for application deployment and support minimize networking infrastructure investments.
  • Application Service Provider (ASP) option provides an all-inclusive hardware, software, hosting and technology management service in addition to the traditional in-house licensed software solution.
  • Load balancing eliminates performance delays regardless of the level of network traffic
  • Single- or multiple-database design, based on organizational preference
  • Open-source databases do not require the purchase of software licenses
  • Remote management flexibility and convenience
  • HIPAA-compliant 128-bit (up to 256) encrypted remote-access security controls
LAN Baseline Architecture Overview—Branch Office Network
  • LAN services provide connectivity to end devices into the corporate network within the office. With the convergence of services onto a single network infrastructure, devices such as computers, telephones, surveillance cameras, cash registers, kiosks, and inventory scanners all require connection to the corporate network via the LAN. This assortment of devices requires simplified connectivity tailored to the demands of each device. For example, devices such as IP telephones or cameras may be powered via the LAN switch, automatically assigned an IP address, and be placed in a virtual LAN (VLAN) to securely segment them from the other devices. Wireless access points may be used to provide secure mobile access for laptop computers, scanning devices, wireless IP phones, or kiosks. These are just a few examples of the LAN services that are used in the Business Ready Branch or Office solution.
  • In addition to providing the integrated voice, video and data services for the employees, branch offices also require guest network access, and in some cases should support demilitarized zones (DMZs). The guest access can be for partners or customers, and guest access includes both wired and wireless access.
  • Regardless of the presence of DMZ, security in branch offices is a key element of branch LAN services. The LAN must be protected against malicious attacks, and the users accessing the corporate network must be authorized / authenticated.
Network Design and LAN/WAN Architecture

From local area networks (LAN), to wide area networks (WAN), connecting more than one location, to municipal area networks (MAN), and to wireless networks (Wi-Fi), we can customize options and packages to your cost-and-feature benefit with your ISP and can handle all of the in-house equipment necessary to make it all hum along smoothly.

  • A network should allow fast, constant, and clear communication – TTS can help you get there.
  • If you already have a network, TTS can maximize its potential and maintain it for you.
VPN and Firewall

TTS can create and maintain Virtual Private Networks for your business, or we can implement alternatives from your ISP which may be less expensive. A VPN allows you to work remotely from any computer with an Internet connection. VPNs provide a safe “tunnel” across the Internet, enabling remote access to the resources in your local network. For the best in hardware security solutions, TTS recommends, installs, and maintains Cisco Security Appliances, such as the Cisco PIX 501 and 506, as well as Cisco ASA devices, to be sure that your network is covered by Intrusion Detection and Stateful Packet Inspection; two key items required under most compliance laws (ie. HIPAA, PCI DSS, etc).
