概要

シグナリングプロトコルDiameterは、最新の技術ではありませんが、近年重要な役割を担うようになっています。これまでシグナリングプロトコルプレーンは、実用的なネットワーク機能を担うものと考えられてきましたが、最近では単にインフラストラクチャを提供するだけの技術ではなく、各種サービス間の複雑な相互作用をサポートし、調整するための重要な技術と認識されるようになっています。Diameter関連の市場は、2012年から2013年にかけて進展したLTEロールアウトなどの動きに後押しされる形で成長を加速させており、有力ベンダーによるDiameter Signaling Controller(DSC)関連技術の買収といった動きも活発化しています。また、ネットワーク機能仮想化(NFV)やソフトウェアデファインドネットワーク(SDN)など、コントロールプレーンを利用して本格的なエンドツーエンドサービスモデルをサポートすることに重点を置いた技術も登場しており、次世代ネットワークにおけるDiameterベースのコントロールプレーンの役割は今後さらに大きくなると予想されます。

当レポートは、進化を遂げつつあるコントロールプレーンの役割を分析し、新たな課題に対して最も効果的に対処できるアーキテクチャの選択肢を検討したもので、Diameterシグナリングとそのエコシステムに関わっている主なベンダー13社のプロファイルも盛り込み、概略以下の構成でお届けいたします。

目次

Although Diameter is not a new protocol, in that initial standardization was completed in 1998, it is now front and center. Today's 3G and 4G mobile networks utilize the Diameter protocol similar to how SS7 is used in 2G mobile networks. As a result, the signaling control plane is attracting a new level of interest among vendors and network operators alike.

It wasn't that long ago that the signaling control plane was considered an important, but fundamentally utilitarian network function. However, the momentum of the Diameter growth market in 2012 and 2013 - in large part fueled by early LTE rollouts - provided the impetus for vendors such as Oracle and F5 to step out of their comfort zone and acquire the Diameter Signaling Controller (DSC) portfolios of Tekelec and Traffix Systems.

While such DSC acquisitions may have seemed somewhat limited synergistically at the time, we believe they in fact reflected another key industry shift: The control plane is now transitioning from simply providing infrastructure to support complex service interactions, to playing a significant role in service orchestration. Adding in the impact of network functions virtualization (NFV) and software-defined networking (SDN) - which are both focused on leveraging the control plane to support a truly end-to-end services model - it becomes clear that the relevance and role of the Diameter-based control plane in next-generation networks will continue to grow.

An entirely new view of the DSC has emerged in the past 18 months. There has been a recognizable shift among network operators and vendors alike, that the control plane is something more important and that a DSC as a central hub is extremely well positioned to support service orchestration. The control plane is now perceived as a natural starting point for virtualization and "cloudification," and the DSC has emerged as a central signaling point of control that would be suited for interfacing with core virtualized nodes such as PCRFs and CSCFs.

Service-Enabling the Control Plane: The Role of Diameter Signaling in Next-Generation Networks analyzes the evolving role of the control plane and ex1amines the architecture options to most effectively deal with these new challenges. The report also profiles 13 leading Diameter signaling and ecosystem vendors, including details of their products, vision and market strategies.

This report also profiles 13 leading Diameter signaling and ecosystem vendors. These profiles capture current and future product capabilities, product differentiators, deployment drivers, market focus, strategic partners and customer footprint.

Aligned with the philosophy of "flattening" IP core networks via IMS, the original view architecturally was that each defined node (e.g., PCRF or CSCF) would support Diameter signaling as required on a peer-to-peer basis. While this technically remains a valid option even today, as large IMS deployments began to scale, concerns have been raised about the viability of this approach. In response, as shown in the excerpt below, support for a standalone centralized signaling node similar to the concept of an SS7 Signaling Transfer Point (STP) to support internal signaling (DRA) and inter-network signaling (DEA) gained support, which resulted in the standardization of both (DRA via 3GPP and DEA via GSMA).

While the DSC is still relatively a new network artifact, like all network nodes, the potential to implement a virtualized configuration aligned with an NFV model is rapidly gaining momentum. As shown in the excerpt below, this represents a third architecture option to the standalone physical centralized node and peer-to-peer configurations captured above.
