MPLS LSPs provide dynamic, transparent virtual networks with support for traffic engineering, the ability to transport layer-3 (IP) VPNs with overlapping address spaces, and support for layer-2 pseudowires using Pseudowire Emulation Edge-to-Edge (PWE3) [29] that are capable of transporting a variety of transport payloads (IPv4, IPv6, ATM, Frame ...
Telesphere is a nationwide Unified Communications as a Service provider for businesses. In 2003, Telesphere began providing highly secure cloud-based voice and data services over a private IP MPLS network to mid and large enterprises throughout the United States and now also in Europe.
The company provides Private IP services and networks, as well as managed WAN and LAN services, [15] [14] among other networking services. [16] [17] Verizon also operates a global IP network that reaches 150 countries. [7] In January 2012, Verizon began its Private IP Wireless (LTE) service, which combines 4G LTE with Verizon’s MPLS IP VPN. [18]
The MPLS Forum (which supported Multiprotocol Label Switching had begun in 2000. Those two merged in 2003 to become the MPLS and Frame Relay Alliance (MFA). In 2005, the ATM Forum joined forces with the MFA to form the MFA Forum, which was renamed to be the IP/MPLS Forum. In May 2009 the IP/MPLS Forum merged with the Broadband Forum. [1]
Ethernet VPN (EVPN) is a technology for carrying layer 2 Ethernet traffic as a virtual private network using wide area network protocols. EVPN technologies include Ethernet over MPLS and Ethernet over VXLAN. [1] [2] EVPN uses encapsulation methods to ensure efficient and scalable transmission of Ethernet traffic over MPLS or IP-based networks.
While Voice over IP (VoIP) is maturing, its deployment requires an investment in new network infrastructure and customer premises equipment (CPE). TDMoIP presents a migration path, whereby modern packet switched networks can be used for transport, while the end-user equipment need not be immediately replaced. TDMoIP was first developed in 1998 ...
On October 13, 2001, TTK officially started commercial operation of its backbone network. [2] In April 2002, the TTK went on the market and support services to the organization of virtual private networks (VPN) technology and Multiprotocol Label Switching (MPLS) IP transit. Among the first customers was TTK Internet service provider Corbina.
Ethernet services are carried over IP/MPLS networks making use of a wide range of IP-related protocols (see IETF pseudowire standards, e.g. RFC 3985, RFC 4448). Ethernet links are transported as "pseudowires" using MPLS label-switched paths (LSPs) inside an outer MPLS "tunnel". This strategy can support both point-to-point (Virtual Private Wire ...
