WHAT IS IP TELEPHONY?
IP Telephony/Voice over IP (VoIP) is the routing of voice conversation over an IP-based public or private data network, the Public Internet or a Virtual Private Network (VPN). The voice is digitized into packets that travel over a data network instead of the traditional dedicated circuit-switched voice transmission lines.
BITS provides end-to-end security by routing voice in dedicated VPN connections instead of over the public Internet. Furthermore, BITS ensures end-to- end VoIP service quality by enabling Quality of Service (QoS). In contrast, other VoIP providers may not be able to offer quality of service when transmitting voice calls over the public Internet, which results in a “best effort” call quality.
WHAT IS MPLS?
Multi-Protocol Label Switching (MPLS) is a converged data network which emulates properties of a circuit-switched network over a packet-switched network. MPLS was designed to provide a unified data-carrying service for both circuit-based clients (voice calls) and packet-switching clients (critical data). It can be used to carry many different types of traffic, including voice, video, image, and data and allows for end-to-end Quality of Service. BITS uses Cisco Integrated Services Routers, which were designed for transmitting converged traffic throughout the BITS MPLS network.
WHAT IS A FIREWALL?
A system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users for accessing VPN’s connected to the Internet. All packets entering or leaving the VPN pass through the firewall, which examines each packet and blocks those that do not meet the specified security criteria. The BITS firewall in monitored 24×7 by Dell Secureworks, the most reliable network security provider in the industry.
WHAT IS CLASS OF SERVICE (CoS)?
Class of Service (CoS) is a way of classifying and prioritizing packets based on application type (voice, video, image transfers, critical data transport, internet access), and the type of user group, based on a queuing mechanism for transmitting converged traffic. It allows financial institutions to optimize response times for latency-sensitive applications while maintaining high throughput for bulk data applications. CoS meets the demand for predictable performance of business-critical applications as well as the requirements for integrating latency-critical voice and video applications with data services calls for differentiated handling of network traffic.
WHAT IS A VPN?
Virtual Private Network (VPN) – VPNs are closed and protected connections, usually configured across the Internet using encryption and other security mechanisms to provide authorized users with access to their company’s internal networks.
