Overview
Service providers are providing businesses that customers want to reuse, hoping to find new revenue-generating businesses that can create high profits to use data networks and reduce customer capital turnover. The most profitable voice and data services have two identical characteristics. One is the "success-based" capital expenditure model, which can accelerate the return on investment (ROI), because service providers can fully utilize their capital investment after winning customers. The other is that it can be used to provide multi-service infrastructure, and service providers can increase the income of unit customers with only a small amount of investment.
In order to accomplish this new mission, Cisco Systems has developed a set of manageable voice business solutions that service providers can deploy to provide small and medium-sized businesses with business and achieve profitability. These solutions include Cisco Hosted IP Telephony, Cisco Managed IP Telephony, and Cisco Multiservice Virtual Private Network (VPN). All these manageable voice business solutions have the following characteristics:
They come through a set of market-leading Cisco AVVID (voice, video, and integrated data architecture) IP telephony solutions, service provider carrier-grade packet-to-speech products and solutions, and key Cisco ecosystem project partner products and solutions. Provided, these products and solutions have been tested and verified.
They provide a richer return on equipment investment costs than traditional time division multiplexing (TDM) voice services, because multiple revenue-generating enhanced services can be deployed in a common network infrastructure.
They allow enterprise customers to outsource their integrated voice and data solutions to a service provider, thereby taking full advantage of and supplementing Cisco enterprise IP telephony expertise and achieving great success in the market.
The Cisco multi-service VPN solution is a viable interconnected network solution that has passed field tests and provides enterprise customers with integrated voice, video, fax, and data services through a shared infrastructure. Service provider customers can make full use of partner knowledge, experience, and infrastructure to reduce equipment investment and operating costs, simplify network management, and accelerate the deployment of IP applications without affecting the performance and security of private networks.
Cisco provides a wide range of multi-service VPN solutions to meet different business and technical needs. The Cisco Managed Transport and Call VPN solution described in this article enables service providers to provide customers with:
Calling scheme for centralized management of managed transmission services using multi-protocol label switching (MPLS) or IP security (IPSec)
Connect to Public Switched Telephone Network (PSTN)
As a multi-service VPN solution provider, Cisco has obvious advantages. As a major provider of enterprise voice and data IP network infrastructure, Cisco has a customer base that occupies the largest service provider market, and they provide manageable voice services. Combined with Cisco's commitment to enhance and support manageable voice services, this makes Cisco's multi-service VPN solution the best choice for lowest risk and highest return.
This article describes the market drivers driving the development of the overall multi-service VPN, Cisco's manageable transmission and calling VPN solutions and their components, and the advantages that the solutions bring to service providers and their customers.
Multi-service VPN market drivers
The continuous improvement of the corporate climate and the continuous evolution of technology have made corporate customers turn their attention to multi-service VPNs and opened up profitable business opportunities for service providers.
Growth of enterprise voice and video applications
Many enterprises are currently using traditional TDM equipment to implement voice and video solutions, connecting multiple sites through dedicated lines. These dedicated network infrastructures provide high performance and security, but using separate networks to provide voice and data services results in wasted costs and underutilized resources. In some cases, enterprises can add packet devices and functions to their traditional networks, but this requires increased equipment investment costs and professional and technical personnel.
At the same time, service providers are very interested in making full use of their existing (and sometimes underutilized) packet networks to directly transmit business-oriented services. Integrating voice and data services into a general packet network provides service provider customers with a more effective solution than expensive private networks or public networks that provide lower quality performance and security Sex. By supplying packet-based multi-service VPN to transmit voice, video, fax and data services, service providers can provide a wide range of cost-effective services and applications-as well as manageable performance and security-to improve customers in the next few years Loyalty to achieve profitability.
VPN market growth
Despite the slowdown in the development of the telecommunications business market, the VPN business market is growing rapidly. A July 2001 IDC report pointed out that by 2005 the global IP VPN market will grow to nearly 21 billion US dollars, a 57% mixed annual growth rate. "IP VPN is finally emerging as a mainstream technology in the world .... It turns out that the IP VPN market is one of the few markets that has not been slowed down by the recent economic shocks that have led to technological development."
Ascending outsourcing
In order to reduce costs and pay more attention to core business competitiveness, enterprise customers are seeking help in deployment and management of domains and WANs. A recent survey conducted by Infonet Research showed that by 2005, 55% of customers surveyed planned to use manageable IP VPN services. In this group, 64% of customers are likely to provide voice and data services. As Business Communications Review said:
"Most enterprises plan to improve the WAN around next year. Enterprise network designers are considering converged backbone networks: quality of service (QoS), voice over IP (VoIP), and IP VPN. In fact, the primary goal of all initiatives is to reduce costs. However, they are constrained by tight budgets and a lack of professionals, and service providers can do much more than help customers use their WAN capabilities. "
A recent Ovum survey predicts that by 2006, the global market for VPNs will exceed US $ 30 billion, with US $ 22 billion in revenue coming from multiservice VPNs, not data VPNs (Figure 1).

Service providers highlight the needs of their business
As the basic IP connectivity business becomes a commodity, service providers that stand out through high-margin, high-use and manageable IP services will gain a competitive advantage. Cisco designed its multi-service VPN solution to enable service providers to quickly provide basic IP transmission and VPN services. Over time, they can make full use of the packet architecture to add other value-added services. The end result is increased average revenue per user (ARPU) and increased customer loyalty.
Business Introduction
Service providers can use the IP network to provide voice and data services to multiple corporate customers by deploying clients and network components, with the help of Cisco's managed transmission and calling VPN solutions. Service providers can provide voice / data services and customizable calling solutions for each enterprise customer in multiple locations. Each enterprise customer can independently use VPN to provide his own site-to-site voice and data services. He can also "hop off" VPN and use PSTN to provide public voice communication services (Figure 2).
Cisco provides a scalable platform and its powerful Cisco IOS® Software to deploy multiservice VPNs on IP tunnels, virtual circuits, or MPLS architectures. By deploying customer-centric VPNs, service providers can create new revenue-generating services or increase revenue through their current dedicated lines, frame relay, or Internet access services.
The Cisco multi-service VPN solution is designed to meet the needs of a wide range of service providers, including long-distance phone operators, alternate exchange carriers, established local phone operators, Internet phone service providers, and video service providers.
