ndis defines parameters for loading more than one protocol on a network adapter
there are a number of protocols used by IM program. some programs like skype uses propriety protocols and are not disclosed and other program like google talk uses open sources. among open source protocols are XMPP and SIMPLE

The key principle of modern networking is the separation of network functionality into independent layers; this is also true in the tele and datacoms industry. The 'layered' thinking is also a very fundamental and visible aspect in a number of standardization initiatives and industry forums, such as Multiservice Switching Forum, led by several of the largest operators and manufactures.3G mobile communication systems are designed with these principles in mind, and hence offer a number of advantages and possibilities. Special attention needs to be put on meeting the requirements for time-to-market, low cost of ownership, openness and future evolution towards an "all-IP" solution.Key characteristics :Offers an open and versatile architecture capable of meeting the current and future demand in a fast changing telecommunications environment.Provides and inherent flexibility for coping with growth and/or changing traffic patterns and traffic mixes.Independence between layers allows each layer to evolve independently.Provides great transport flexibility and allows different transport technologies, both existing and new. To be deployed without impacting the control or services/application layers.Allows common transport arrangements for multi-services network.Allows access independent and seamless services through a common service/applications layer.Provides efficient use of network resources.Relies on proven and stable protocols and design.Allow a very flexible re-use of investments in the GSM infrastructure.
source and destination port number or two applications communicating the data
EIGRP uses port no. 88, but it is not use TCP or UDP, it's uses RTP(Reliable Transport Protocol).
Port Number
a sequence number allows the transport layer functions on the destination host to reassemble segments in the order in which the were transmitted
In order to tell the difference between different data segments the transport layer assigns an identifier to an application. The TCP/IP protocols call this identifier a port number. Each software process that needs to access the network is assigned a port number unique to that host. This port number is used in the transport layer header to indicate to which application that piece of data is associated. Hope this helps!!!

Gmail uses the technology or the protocols to send mails. It works on port number 487 for SSL. IMAP and SMTP are the protocols used.
Transport number is the fraction of the total current carried by a given ion in an electrolyte
they have a number of transport such as:cars, trains, bikes and trams
The default port number depends on the protocol. If a URL starts, for example, with "http://", then the default port number will be 80. For other protocols, other default port numbers are used.The default port number depends on the protocol. If a URL starts, for example, with "http://", then the default port number will be 80.
