Metaswitch White Papers

Which of our white papers are you interested in? (Please note that you must check at least one of these boxes in order to proceed to download.)

PCE - An Evolutionary Approach To SDN: This white paper focuses on the operational advantages and extra capabilities that PCEs bring to MPLS and GMPLS networking. These include enabling secure, dynamic, optimal, and private inter-area and inter-domain traffic engineered path setup.
Session Border Controllers in IMS: This white paper explores how far the capabilities offered by SBCs can be explained in terms of IMS functions, and notes where the IMS standards are insufficient to describe all of the required real-world features. It also explains what an SBC designed for deployment in an IMS network should look like, and how this requirement is likely to evolve.
P2MP RSVP-TE and its application for IPTV: This paper explains the point-to-multipoint (P2MP) extensions to RSVP-TE and the applications of, and requirements on, P2MP TE LSPs. It also discusses P2MP TE LSP's relation to the delivery of broadcast video and IPTV.
Strategies for Preserving Legacy Terminal Devices in Enhanced Networks: This paper discusses how devices on legacy SNA networks can be retained while improving the connectivity to the central systems that control them.
Session Border Controllers: Enabling the VoIP Revolution: This paper provides a general introduction to SBCs and describes the deployment scenarios in which they are used today.
IP Multicast Explained: This paper gives an overview of the most important network-layer protocols used in multicast, providing a guide for developers or network managers familiar with unicast routing but new to multicast.
Inter-Area Routing, Path Selection and Traffic Engineering: This paper provides an introduction to Inter-Area Routing, but will be of particular interest to carriers aiming to provide multiple area QoS support to their customers and equipment manufacturers constructing devices that can make this happen.
SIP Market Overview: This paper provides an overview of the Session Initiation Protocol (SIP) and its expanding applications, and explains how the protocol is evolving to meet their new requirements.
Techniques for Integrating SNA-based Systems into IP Networks: This paper discusses the four main techniques for integrating SNA systems into IP: TN3270; data link switch (DLSw); proprietary 'split-stack' solutions; and Enterprise Extender (also known as HPR/IP or IP-DLC).
VPN Technologies - a comparison: This paper gives an overview of the technologies currently being studied for VPN solutions, focusing mainly on VPNs where the management and maintenance is outsourced to a service provider.
ASON and GMPLS - a comparison: This paper describes how contributions from the ITU, OIF, and IETF are contributing to the development of optical networks.
Protection and Restoration in MPLS Networks: This paper examines the features inherent in MPLS networks that facilitate high availability by protecting MPLS LSPs against failures of network resources.
MPLS in Optical Networks: This paper discusses some of the technical challenges that have arisen in the process of applying MPLS to optical networks, and the technologies that have now been developed to address those challenges, including Generalized MPLS (GMPLS), Link Management Protocol (LMP) and OIF UNI.
Soft PVCs in an ATM Network: This paper provides a detailed analysis of the benefits of using Soft PVCs, and includes a discussion of our proprietary solution for protection-switched SPVCs.
MPLS Virtual Private Networks: This paper reviews the requirements placed on a base technology for VPNs, how MPLS meets these requirements, and the state of the ongoing standardization efforts within the IETF.
MPLS Traffic Engineering: A Choice of Signaling Protocols: This paper presents an analytical and unbiased comparison of RSVP and CR-LDP in supporting traffic engineered LSPs.
