Genevieve Santos Tina Nunez Jose Lugo Eddie 08/22/2014 Frame Relay Migration to MPLS Frame Relay is a standardized wide area network technology that specifies the physical and logical link layers of digital telecommunications channels using a packet switching methodology. Multiprotocol Label Switching (MPLS) is a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses

internal system from the outside the company via the internet on any open ports. A firewall will also prevent internal network users from accessing certain internet sites which could be dangerous or offensive (Shay‚ 2004). The firewall acts at the OSI model ’s layers three and four by searching packets for certain types of headers (Shay‚ 2004). So‚ firewalls differ from file security because anyone inside the company can theoretically access files behind the firewall‚ while file security provides internal

communicate effectively. A protocol sets the fundamental rules which allow data to be shared between computers. A standard works alongside the protocols making sure that the hardware is compatible amongst similar computers. The open system interconnect (OSI) mdel has seven layers for communication and network protocols. The layers consist of presentation‚ application‚ session‚ transport‚ data‚ network and physical. These standards are the platform from which computers communicate. During this communication

Discuss the purpose of internet layer TCP/IP Suite Protocol? * TCP/IP PROTOCOL SUITE Communications between computers on a network is done through protocol suits. The most widely used and most available protocol suite is TCP/IP protocol suite. A protocol suit consists of a layered architecture where each layer represents some functionality which can be carried out by a protocol

deployed‚ and what issues still need to be addressed. MPLS operates at an OSI Model layer that is generally considered to lie between traditional definitions of Layer 2 (data link layer) and Layer 3 (network layer)‚ and thus is often referred to as a "Layer 2.5" protocol. It was designed to provide a unified data-carrying service for both circuit-based clients and packet-switching clients which provide a datagram service model. It can be used to carry many different kinds of traffic‚ including IP packets

system that automatically cuts over to a large diesel motor generator set. The hospital uses a network bridge to interconnect its logical network. A network bridge connects multiple network segments at the data link layer‚ which is Layer 2 of the OSI model. The Data Link Layer enables data to be transferred between network entities and might provide the means to detect and possibly correct errors that may occur in the Physical Layer. The hospital’s network is an Ethernet network. The Ethernet network
