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

Fixed-Line Transformation NFV (Network Functions Virtualization) Cloud White papers 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.

Huawei Path Computational Element (PCE) for E2E Multidomain Networking case study

Cloud Case studies Networking software SDN (Software Defined Networking) PCE (Path Computational Element) Layer 3 MPLS (Multi-Protocol Label Switching) Huawei

Huawei’s selection of DC-PCE protocol software from Metaswitch was an expansion of the existing 10-year old relationship between the two companies. Over that time Huawei has turned to Metaswitch for a full suite of control plane technology, including IP routing, MPLS and GMPLS software. Metaswitch has extended its control plane solutions with DC-PCE, with full integration of the routing and GMPLS software. Huawei selected Metaswitch for its PCE solution due to the pre-integration and Huawei’s familiarity with Metaswitch’s high quality and exceptional support.

"Intelligent aggregation" white paper

Cloud White papers SDN (Software Defined Networking) Layer 3

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 guide to NFV and SDN" white paper

NFV (Network Functions Virtualization) Cloud White papers SDN (Software Defined Networking)

This paper is intended to help network operators understand the key technologies that support this transformation in networking, namely Network Functions Virtualization (NFV) and Software-­‐Defined Networking (SDN); to assess how these technologies could be applied in their networks; and to identify the kinds of benefits that could flow from embracing them.
