ACG white paper: SDN and NFV - The Missing "Organizational Readiness Plan"

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

The telecom industry is facing its biggest disruption. The move to SDN, NFV and virtualization is revolutionary, yet indispensable for any telecom operator. However, the current industry discussions have mainly focused on the technology, with little or no dialogue on the operational side.

What is Path Computation Element (PCE)?

Network Protocols SDN (Software Defined Networking) PCE (Path Computational Element) MPLS (Multi-Protocol Label Switching)

Path Computation Element (PCE) is a device that computes paths on behalf of the nodes in the network. It can be a router, a COTS server, part of the OSS, or a virtualized entity running in a cloud. When a network node needs a path for an LSP, it makes a request to the PCE using the PCE protocol (PCEP). The PCE has access to topology information for the entire network and uses this in path computations.

Virtual Route Reflector datasheet

NFV (Network Functions Virtualization) Cloud Datasheets SDN (Software Defined Networking) Virtual Route Reflector

With the insatiable demand for bandwidth and an unstoppable drive towards ever-increasing connected endpoints, elastic scalability and granular control of IP infrastructure has never been more important. A virtual network function (VNF) architected for NFV implementations, the Metaswitch Virtual Route Reflector (vRR) is designed as a robust solution for both internal BGP scaling and as a central control plane component within Carrier SDN solutions.

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

Cloud Case studies Network Protocols 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.
