Session Initiation Protocol (SIP) is an internet signaling protocol, developed by the IETF (starting in 1996), for establishing, maintaining, and tearing down sessions between a variety of real-time media, including voice, video, and chat. SIP allows endpoints to locate other endpoints, whether stationary or mobile. SIP doesn't have to worry about transporting voice or video as Real Time Transport Protocol (RTP) takes care of that. It also relies on Session Description Protocol (SDP) to negotiate capabilities and codecs. SIP does not provide a Directory Service or Authentication, but it does work with services such as LDAP or RADIUS. SIP is only concerned with signaling. This white paper is going to look at the way SIP is used in the converged Unified Communications environment.

This white paper has three main goals. The first is to generate a better understanding of the cloud in both the business and IT communities. The second is to describe the major components of vCloud and the virtual datacenters they provide. The third is help businesses visualize and understand how vClouds could be beneficial in addressing their specific IT needs.

VMware vCloud Director fashions the provisioning of the software-defined datacenter layer to allow for a full virtual datacenter deployment within a short period of time. A vCloud consists of many layers and can quickly become a complex architecture. Before any deployment, requirements should be defined so that the vCloud can be designed to offer those services needed. It is imperative to understand the many components of vCloud, how each vCloud construct fits, which allocation models are available, and what network options can be chosen.

Here are seven tips for working with vSphere, including: Logging in via Command Line, dealing with connection problems using ssh to an ESXi host; network performance issues; possible storage problems; Log Files to View in vSphere ESXi 5; network performance troubleshooting; migrating to a virtual machine using VMotion.

Network security is everyone's concern, and this applies to computer security as well. Many security breaches occur due to user ignorance of basic security principles, not malicious intent. Network and computer security are like an onion - there are multiple layers. Good security begins with understanding what you can do to keep your systems safe and implementing a layered approach. If you depend on one program or feature to secure your computer, then when (not if, but when) that dependency is breached, you may have personal information stolen or even have your computer taken over.

In a recent post, I gave an overall description of a service portfolio and the key components of a portfolio. Here, I will describe how a cloud services provider might implement an ITIL service portfolio. A cloud services provider will regularly have a set of services under development, a set of service in live operation, and a set of services that are retired.

As mentioned in last week’s post, interviews that require ITIL Intermediate level knowledge will most likely be targeted to specific process areas and activities. If I interviewed someone for a job that required ITIL Intermediate level knowledge, in addition to other questions about the specific technical responsibilities of the job, I might ask the following questions:

The demand for skilled business analysis (BA) professionals is on the rise, and a great way to declare your expertise is with a BA certification. But which BA certification is right for you: PMI-PBA, CBAP or CCBA? Here is a look at the eligibility requirements and steps for obtaining each.

Increased interconnectivity via machine-to-machine (M2M) communications, the IoE, and smart systems holds profound implications for how business trends continue to evolve. In terms of M2M growth, key developments in security will be essential, from the design and manufacture of devices to more robust cloud security and ensuring the integrity of wireless data transmissions. Without these safeguards in place, organizations and industries that rely on M2M will continue to place themselves at risk.

Risk is something we deal with on a daily basis. Living in New Jersey and having the occasional storm, I’ve recently performed my own risk assessment determining the value of certain assets and activities and made a decision on what I was willing to spend to reduce risk to what I perceived as an acceptable level. My management of risk was a rather simple case. Sure, in my revised business continuity plan for my home, I’ll make sure that I have more D cell batteries, have my garage door adjusted so it opens manually again, more food I can heat on a stove and that doesn’t rely on refrigeration, and finally I’ll consider a whole house gas generator that uses natural gas, which has always been available to power critical systems like the sump pump in my basement. What if, however, I was a really large business? One with lots of components and interdependencies that require a tight integration in order to succeed? How and where can a large volume of information necessary to management, business continuity, and disaster recovery be correlated and communicated to those individuals who, because of their roles and responsibilities, need to make the critical decisions regarding the management of risk?

As IT professionals gravitate away from classroom training and toward on-demand courses and e-learning, IT skills gaps have spiked. Instructor-led training is still the best option to fill critical skills needs and shouldn't be pushed aside entirely for more convenient and cost-effective options.

Has your company implemented "reasonable security"? If so, you should be able to avoid lawsuits and fines after a breach. But what is "reasonable security," and is there a definition?

If you work in IT, there is no doubt that you've lived through more than a few IT nightmares. In celebration of Halloween, we've asked a few of our instructors to share some of the horror stories from their own consulting careers.

AMC’s television series “Halt and Catch Fire” shows North Texas’ rise as the “Silicon Prairie.” In the 1980s and early 1990s, it’s where IBM PC cloning was explored and where first-person shooter games were created. It’s also the site of the first “logic bomb”—the source of my horror story.

What we love about our annual IT Skills and Salary Survey is that IT professionals are thoughtful and honest with their answers … well, sometimes a little too honest. Here are actual open-field comments from the 2019 survey. #ITGetsReal

In this video, instructor Charles Strother does a quick overview of what is needed to install a Read-Only Domain Controller (RODC) in a Windows Server 2008 environment.

The STP (Spanning Tree Protocol) standard (IEEE 802.1d) was designed when the recovery after an outage could wait a minute or so and be acceptable performance. With Layer 3 switching in LANs, switching began to compete with routers running protocols because they are able to offer faster alternate paths. Rapid Spanning Tree Protocol (RSTP or IEEE 802.1w) brought the ability to take the twenty seconds of waiting for the Max Age counter plus fifteen seconds of Listening plus fifteen seconds of Learning or fifty seconds down to less than one second for point-to-point connected and edge switches and six seconds for root switches.

Most project team members report to a functional manager who controls their assignments, performance appraisals, raises, bonuses, etc. Until recently, project managers (PMs) had little input into any of these processes. In this paper, learn how a PM working in a functional or matrix organizational structure can get team members to perform.

Project Scope Management sets the foundation for the creation, development and successful delivery of a project. Learn about the project management process here.

Agile project management literally turns the world of managing projects upside down. The triple constraint is balanced in an unconventional way, the role of the matrix team coordinator is downplayed, and risk management can be built into the prioritization approach. So, what is left for the PM to do?

Change managers and project managers come at the same goal of maximizing ROI for their organizations, but from different perspectives and approaches and with different skill sets. While project managers are responsible for achieving specific objectives on time and on budget, the change manager's role is broader. Change managers apply a structured approach to helping individuals, teams and organizations negotiate relentless change. A project manager turns ideas into reality. Increasingly, project managers are required to take on the role of change manager as well. Business today can't afford to carry out tasks without considering the larger picture. Today, integration is unavoidable - and expected. In this hour-long interactive session, we'll discuss the similarities and differences between project management and change management. We'll also identify the occasions when both a project manager and a change manager might be needed.

Most organizations quickly realize that knowledge management must be integrated with incident management in order to improve the quality of service and the efficiency of providing assisted service. What is not as quickly recognized is the value of integrating knowledge management with problem management.

In many organizations, the Program/Project Management Office (PMO) is viewed as purely a cost center, so it becomes marginalized by additional layers of bureaucracy, oversight and cost. But the essence of the PMO and portfolio management in general is to add value to the organization. So how do organizations reconcile the cost of the PMO versus the value it adds? The short answer is to flip the conversation on its head and talk about the PMO as a revenue driver rather than a cost center. In this hour-long webinar, Global Knowledge PMP-certified senior product manager Daniel Stober will explain how, by focusing on efficiencies gained and reduced waste, you can shift the conversation from the PMO being a necessary evil to the PMO being critical for organizational success.

What is PBR? Policy-Based Routin (PBR) is the process of using a route map to match on something more than the destination and then defining the path out of the router based on those conditions. PBR could match on destination only, but typically we would match on more. PBR is considered to be an exception to the RIB and is looked at before examining the RIB.

Policy-based routing (PBR) provides network administrators with agility and flexibility to better manage traffic. With carefully architected policies, you can optimize how segments of your network process data, as well as how bandwidth is managed for business-critical applications.
