“Telco-grade” in the cloud: deploying reliable VoIP in NFV environments

VoIP (Voice over Internet Protocol) NFV (Network Functions Virtualization) Cloud White papers Consumer communications high availability (HA)

Network operators want to take advantage of the flexibility, cost savings and increased agility that Network Functions Virtualization (NFV) offers them. However, they still need to provide traditional “telco-grade” services, including offering their end-users SLAs of five-nines availability or higher with strict call cutoff targets. Providing telco-grade services in the cloud presents a technical challenge but is achievable.

In this white paper, we examine the issues involved and show how network operators can achieve these goals.

Virtualized PoPs: From Concept to Reality

SBC (Session Border Controller) Perimeta virtualization White papers Network interconnect

Wholesale carriers are now under constant pressure to reduce cost, improve quality, flexibility, efficiency and global reach, all this while increasing speed of innovation. Not a small order. Virtualization and automation are two of the tools that are now available to carriers to enable a complete shift in their network deployment and operation, which should enable them to better compete with the new breed of telecom service providers.

This white paper provides the background on those technology and business changes and offers an insight into why wholesale carriers need to be reacting now to this latest opportunity before it becomes a threat to their livelihood.

Session visibility in a virtualized world

NFV (Network Functions Virtualization) virtualization Service Assurance Server White papers

Network operators must be able to diagnose and troubleshoot problems as they arise in the network. When there are problems, they need to be able to get to the heart of them quickly and efficiently. They need to reliably determine its root cause and address it, fast. Every second of delay could be hundreds of annoyed customers or thousands of dollars of lost revenue as peers route their calls elsewhere, and perhaps don’t come back. As network operators leverage Network Functions Virtualization (NFV) and Software Defined Networking (SDN) to rapidly roll out new services, increase service flexibility, reduce capital and operational expenditures, and become more agile, Service Assurance (SA) has struggled to keep pace. Part of SA’s struggle stems from the challenge of maintaining continuous SIP session visibility both within a virtual infrastructure as well as across hybrid physical/virtual environments.

Jon Arnold's SMB VoIP 2015 white paper

VoIP (Voice over Internet Protocol) White papers Business communications

This white paper validates the opportunity for IP communications and guides service providers in approaching the small and midsized business (SMB) market. For service providers currently in-market or those looking to enter the market, the research shows there is sufficient interest to merit a strong push. Primary reasons revolve around: (a) a large market still using legacy systems; (b) a need to improve productivity and better integrate remote workforces; and (c) greater understanding of how cloud-based solutions can improve flexibility and reduce costs. Reinforcing that are customers that have already made the move to IP. These companies show overwhelming happiness with IP across several criteria, including cost, product performance, and functionality. Based on these and other factors, this analysis provides the basis for developing a winning value proposition to target the SMB market.

The Network Software Provider: A New Vendor Category

White papers Corporate NFV

Network operators that embrace NFV will make fundamental changes to their supply chains. To minimize hardware costs, network operators will want to purchase their generic NFV infrastructure from high-volume vendors of general-purpose hardware, vendors that, in general, have very little knowledge of specialized network functions such as provider edge routers or IP multimedia subsystems (IMS). To procure the software that will provide those specialized network functions, they will need to turn to vendors that combine an in-depth understanding of the network functions with the ability to implement them efficiently in software on generic hardware. This is the type of vendor that we refer to as a Network Software Provider.

"Intelligent aggregation" white paper

White papers SDN (Software Defined Networking) Layer 3 Cloud network virtualization

Changes in the traffic patterns in large carrier networks have challenged design rules and accompanying economics and planning rules. By assessing these shifts in traffic patterns, and optimizing the architecture for the new reality, the operational complexity of the network(s) can be reduced, and CAPEX spend that can be reduced by up to 75% over existing approaches.

This use case will look at traffic that transits through a single exchange or PoP of a carrier’s network, but does not traverse the carrier’s backbone. This traffic pattern can be referred to as intra–exchange transit traffic.

"A fresh look at session border control" white paper

SBC (Session Border Controller) Perimeta White papers

A new solution for session border control is required that enables signaling and media capacity to be scaled independently of one another, and that delivers far greater scalability in the signaling plane. Such next-generation solutions for session border control are finally starting to become available. Service providers would do well to re-evaluate their SBC deployment plans so as to avoid over-investing in architectures that are ill-matched to their medium and longer term SIP services strategy.

"Session border control in the Cloud" white paper

SBC (Session Border Controller) Perimeta NFV (Network Functions Virtualization) White papers

In the Session Border Controller space, standards have been in place for several years that support the separation of the signaling plane from the media plane – using H.248 as the control protocol between the signaling border element and the media border element. Most current SBCs are based on an integrated architecture that handles signaling and media in the same box, but there are exceptions, such as the Perimeta SBC product from Metaswitch.
