Satellite Internet vs. Ethernet: Why Satellite is Years Behind

There are plenty of times and places to apply satellite based network services. Many people who have remote locations run an entire branch on one satellite modem. However for a larger network infrastructure or for packet heavy communications, Ethernet services perform vastly better. That’s why businesses are weighing satellite internet vs. Ethernet.

Understanding How Packets Create Network Speed and Quality

Even Satellite Today understands the problem that even advanced satellite modems encounter, data packet partitioning. When information passes through a network, it sends packets of data to the end destination. These packets can be large or small, but each bit of information that needs to be passed is bunched into a packet for the network.
Satellite modems are very capable of sending large packets of data, however they run into issues if they need to send a lot of packets, such as 20 people using VOIP providers to communicate. The modem may be able to handle eight large packets of data, but when it starts to receive more packets than it can handle, quality will suffer if the modem has fail safe protocols, or lock up and reboot. For this reason, it is especially important to carefully consider not only the data speeds of the satellite modem, but also the packet capacity as well.
Ethernet services work on a slightly different principle to take advantage of the hardwired, reliable connections called Asynchronous Transfer Mode, or ATM for short. Instead of allocating a number of packets and sending large volumes of data across the network, Ethernet modems chop up that large data into smaller packets and give them a 16-bit code of address information called an ATM tax in the IT world. This packet allocation protocol allows the network to handle infinite number of packets coming through because at the receiving end, that 16-bit address line tells the receiving modem how the packet is meant to be reassembled.

What Does This Mean to the Large and Small Business Owner?

There are some remote locations where satellite internet is all that is available. In those situations with smart IT planning, a hybrid system of Ethernet routing and a satellite modem can adequately satisfy the needs of the business or operations. However, the reason satellite internet is years behind, is that even with a well managed suite of Ethernet services, the satellite modem and data transfer protocols will always be a bottleneck that can be compensated for, but never alleviated.
An Ethernet based network resulting in a cable or fiber-optic network connection creates a lateral network. Rather than data circulating naturally, only to slow down at the smallness of the pipeline, Ethernet with its ATM protocol can perform almost outrageous feats of networking such as sending one ultimate data files through two routers using standard ATM packets, coping with hundreds of different packet sources requiring data communication of both large and small file size, and Ethernet services also provide IT teams many opportunities to redesign the network to alleviate congestion, or clamp down on an insufficient network.

Making the Ultimate Decision

When deciding on your routing and modem technologies, you the business owner know best what to do for your company, but consider these pivot points before you invest too much in either technology.
  1. Consider the actual size of data files passed over the network.
  2. The number of packets transferred at one time, think about how many computers, devices, and VOIPs are connecting to the modem.
  3. Fiber-optic and cable line development, which can give you more bandwidth often at a cheaper rate, which disfavors satellite.
  4. A long distance from cable and fiber-optic services make satellite ideal
I hope this explains Satellite Internet vs. Ethernet. I’d love to hear your comments.

SharePoint 2010 - Access denied for users that have full control on the site

Scenario:

  • Users get "Access Denied" over the whole site, despite having Full Control permission
  • Site Collection Administrators have no problem logging in
Explanation:

A SharePoint 2010 site that uses claims-based authentication has been extended to Intranet zone that uses AD as well as FBA. The site has number of users in the default owners and members groups.
All the site users always get access denied over the whole site even though they clearly have access to the site through the site groups.
Site Collection Administrators are allowed to access the site and have no problems logging in.
Resolution:


Make sure that all the Master page, CSS files, any other files that are required are published.
If there are files that are required in the master pages and are not published, users will get access denied even if they have full control on the site.
If you are ok with giving all authenticated users atleast road-only access to all files inorder to prevent the access denied problem, then you can try the below.
Add a new "User Policy" for the web application that allows "All Authenticated Users" the permissions "Full Read" on the desired zone.
To add a new User Policy:


Go to Central Administration
Click on Application Management
Click on Manage Web Applications

Choose the desired web application:


Click on "User Policy"


Click on "Add Users" to add a new User Policy:



Select the zone that you want to apply the new policy to. If you are not sure what to choose, leave the defaut value selected (All Zones) and cick next


Choose the permissions that you would like to give to the user(s) in this new user policy. If you do not want to give the user(s) full permission, choose "Full Read". This permission ensures that all the users in this policy can atleast access the site. Then click on "Browse" icon in the "Choose Users" area.


If you would ike to give All Authenticated Users / AD users / FBA users "Full Read" access, then choose the appropriate group(s).
In the next screens, click OK to get out of the wizard.
Your new user policy should be ready now.

Error: Only machine administrators are allowed to create administration service job definitions of type

Issue:

Tried to deploy a custom solution on a SharePoint 2010 farm from Central Administration > System Settings > Manage Farm solutions. I received the following error in the ULS logs.

Access denied. Only machine administrators are allowed to create administration service job definitions of type: Microsoft.SharePoint.Administration.SPSolutionDeploymentJobDefinition, Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c

Fix:

This fix only needs to be run on the machine that you are trying to deploy the solution on. However I would recommend disabling this “feature” on all SharePoint and SQL Servers in your farm.

Follow “to turn off UAC” http://technet.microsoft.com/en-us/library/cc709691%28WS.10%29.aspx

1. Click Start, and then click Control Panel.

2. In Control Panel, click User Accounts.

3. In the User Accounts window, click User Accounts.

4. In the User Accounts tasks window, click Turn User Account Control on or off.

5. If UAC is currently configured in Admin Approval Mode, the User Account Control message appears. Click Continue.

6. Clear the Use User Account Control (UAC) to help protect your computer check box, and then click OK.

7. Click Restart Now to apply the change right away, or click Restart Later and close the User Accounts tasks window.
