CALM DURING THE STORM:Best Practices in Multicast SecurityJohnson Liu
Internet multicast introduces a range of new security threats to a network. These threats are not necessarily any more or less destructive than those found in unicast-only networks, but they represent a new class of vulnerability that may be unfamiliar to those with minimal multicast experience. Juniper Networks® Junos® operating system offers the most comprehensive set of features in the industry for securing a multicast infrastructure. This expertise comes from lessons learned after more than a decade of deployment experience in the world’s largest Internet backbones. The following is a detailed set of recommended best practices for securing a multicast infrastructure of Juniper Networks routers.

T Series Core Router Architecture Review (Whitepaper)Juniper Networks
Juniper Networks® T Series Core Routers have been in production since 2002, with the introduction of the Juniper Networks T640 Core Router. Since that time, T Series routers have evolved to maintain an unequivocal industry lead in capacity (slot, chassis, and system) and operational efficiencies in power and usability. Maintaining this standard has in part been possible due to design decisions made with the very first T Series system. The T Series demonstrates how Juniper has evolved its router architecture to achieve substantial technology breakthroughs in packet forwarding performance, bandwidth density, IP service delivery, and system reliability. At the same time, the integrity of the original design has made these breakthroughs possible. Not only do T Series platforms deliver industry-leading scalability, they do so while maintaining feature and software continuity across all routing platforms. Whether deploying a single-chassis or multichassis system, service providers can be assured that the T Series satisfies all networking requirements.

Validation is done through checking the control and data plane operation, including PIM states and multicast traffic flows.
This white paper discusses the evolution from circuit-switched to packet-based core networks. It notes that most modern communications, including voice calls, video, and file transfers, are delivered via packets. However, some core networks have not fully converged on packet transport, still relying on legacy circuit-switched infrastructure that is more costly and complex. The paper examines different transport technologies and argues that a fully packet-based approach using next-generation packet switches can optimize costs while improving scalability, manageability and bandwidth utilization compared to hybrid circuit-packet networks.
Unified communications applications provide benefits in employee collaboration, mobility, and cost savings according to a survey of 244 organizations:
- 49% of organizations reported employees save up to 20 minutes per day reaching coworkers on the first attempt with presence and IM integration.
- 50% of organizations saw up to 20 minutes in daily savings per employee from escalating IM chats into web conferences.
- 64% of organizations experienced reduced travel costs of over 10% from increased conferencing and collaboration capabilities.

The document covers GDPS/PPRC, which uses IBM's Peer-to-Peer Remote Copy (PPRC) technology for continuous availability and disaster recovery. It also addresses infrastructure planning considerations for GDPS implementations.
The IT industry has gained significant efficiency and flexibility as a direct result of virtualization. Organizations are moving toward a virtual datacenter (VDC) model, and flexibility, speed, scale and automation are central to their success. Although compute and memory resources are pooled and automated, networks and network services, such as security, have not kept pace. Traditional network and security operations not only reduce efficiency but also limit the ability of businesses to rapidly deploy, scale and protect applications. VMware vCloud® Networking and Security™ offers a network virtualization solution to overcome these challenges. This paper describes various components of the network virtualization solution and explains one of the key technology - VXLAN. It also provides design considerations that will help virtualization and network architects deploy this solution successfully in their environment.
The document is a user guide for the Zebra XiIIIPlus series of high-performance printers. It contains information about setting up the printer, loading media and ribbon, operating the printer, and print modes and options. The guide includes sections on unpacking and inspecting the printer, selecting a site and power source, connecting data and communication interfaces, calibrating sensors, and adjusting printhead pressure and toggle position. It provides instructions and specifications to properly set up and operate the XiIIIPlus printers.
The document discusses cloud computing and its advantages. It notes that cloud computing enables higher IT efficiency through technologies like virtualization which allow companies to reduce capital expenditures and convert IT costs to operating expenses. Cloud computing also allows for faster and more flexible application development by providing on-demand access to computing resources. Finally, the document discusses how cloud computing is driving new business opportunities through compelling ecosystem models.
This document provides an overview of the Omniture Suite user manual. It describes the system requirements, including supported browsers and additional installed applications. It also provides contact information for account support and describes persistent areas of the Omniture Suite interface, such as dashboards, reports, and administration tools.
This technical report describes a virtualized Microsoft Exchange, SQL Server, and SharePoint solution using VMware vSphere and NetApp storage. It evaluates three storage protocols: Fibre Channel (FC), iSCSI, and NFS. For the FC solution, the report details the hardware requirements, including NetApp FAS storage arrays, disk shelves, Ethernet and FC networking components. It then describes the FC storage architecture and layout, including aggregates, volumes, and VM datastores. Performance tests validate the storage efficiency, workload performance, and backup/restore capabilities of the FC-based virtualized Microsoft application environment.
