TCP/IP Protocols

TCP/IP is a large collection of different communication protocols.

A Family of Protocols

TCP/IP is a large collection of different communication protocols based upon the two original protocols TCP and IP.

TCP - Transmission Control Protocol

TCP is used for transmission of data from an application to the network.
TCP is responsible for breaking data down into IP packets before they are sent, and for assembling the packets when they arrive.

IP - Internet Protocol

IP takes care of the communication with other computers.
IP is responsible for the sending and receiving data packets over the Internet.

HTTP - Hyper Text Transfer Protocol

HTTP takes care of the communication between a web server and a web browser.
HTTP is used for sending requests from a web client (a browser) to a web server, returning web content (web pages) from the server back to the client.


HTTPS - Secure HTTP

HTTPS takes care of secure communication between a web server and a web browser.
HTTPS typically handles credit card transactions and other sensitive data.


SSL - Secure Sockets Layer

The SSL protocol is used for encryption of data for secure data transmission.


SMTP - Simple Mail Transfer Protocol

SMTP is used for transmission of e-mails.


MIME - Multi-purpose Internet Mail Extensions

The MIME protocol lets SMTP transmit multimedia files including voice, audio, and binary data across TCP/IP networks.


IMAP - Internet Message Access Protocol

IMAP is used for storing and retrieving e-mails.


POP - Post Office Protocol

POP is used for downloading e-mails from an e-mail server to a personal computer.


FTP - File Transfer Protocol

FTP takes care of transmission of files between computers.


NTP - Network Time Protocol

NTP is used to synchronize the time (the clock) between computers.


DHCP - Dynamic Host Configuration Protocol

DHCP is used for allocation of dynamic IP addresses to computers in a network.


SNMP - Simple Network Management Protocol

SNMP is used for administration of computer networks.


LDAP - Lightweight Directory Access Protocol

LDAP is used for collecting information about users and e-mail addresses from the internet.


ICMP - Internet Control Message Protocol

ICMP takes care of error-handling in the network.


ARP - Address Resolution Protocol

ARP is used by IP to find the hardware address of a computer network card based on the IP address.


RARP - Reverse Address Resolution Protocol

RARP is used by IP to find the IP address based on the hardware address of a computer network card.


BOOTP - Boot Protocol

BOOTP is used for booting (starting) computers from the network.


PPTP - Point to Point Tunneling Protocol

PPTP is used for setting up a connection (tunnel) between private networks.

Calculate how much data can be transferred in 24 hours based on link speed in data center

  In case you are planning for migration via DIA or IPVPN link and as example you have 200Mb stable speed so you could calculate using the below formula. (( 200Mb /8)x60x60x24) /1024/1024 = 2TB /per day In case you have different speed you could replace the 200Mb by any rate to calculate as example below. (( 5 00Mb /8)x60x60x24) /1024/1024 =  5.15TB  /per day So approximate each 100Mb would allow around 1TB per day.

Recreating a VMFS-3 or VMFS-5 partition table in ESXi 5.x

For this kind of issues you need to engage VMware support on this, following any part of this article could lead to more complex situation if not ran by an expert.   Symptoms Datastore does not mount because of a lost or overwritten partition table.   Purpose When a VMFS partition is created in ESX 3.x or ESX 4.x, it has a Master Boot Record (MBR) partition map. The MBR is written to the first 512 B block (LBA0) and contains the information where the (VMFS) partition starts and ends. ESXi 5.0 introduced VMFS-5, which uses a GUID partition table (GPT) for new datastores. When a VMFS-3 partition is created in ESXi 5.x and is later updated to VMFS-5, the original partition map (MBR) is maintained. If the partition information of a VMFS datastore is deleted or overwritten (for example, by a Windows system with direct access to the same disks), it is impossible to determine if the partition map was GPT or MBR. The only time you can be sure that a GPT partition map was used is if th...

How to deploy an OVA in Cloud Director

  How to deploy an OVA in Cloud Director Yesterday I was in a call with a customer and we discussed uploading OVA’s into Cloud Director. I said sure that is no problem at all. Well then I started thinking how are you supposed to deploy an OVA in Cloud Director because I do not even remember how this is done. So I opened up Cloud Director and tried it for myself. I decided to make this blog post along the way to show you how to deploy an OVA in Cloud Director. As an added bonus I will also show you how to upload an OVA to the catalog. This way I can deploy the OVA over and over again. Environment information Cloud director 10.3 OVA How to deploy an OVA in Cloud Director In Cloud director I opened up the Applications section and selected “NEW” I am deploying an OVA so I selected “Add vApp From OVF”. In the screenshot below you can see all the steps involved with (in my case) deploying and customising the Usagemeter. Options to customise are for instance: Network settings, vApp naming...
