Idea of “The IEEE standardized protocol”-Part-8

 IEEE standardized

Packet switching :

Service in which each DTE device connects to a telco using  a single physical line,with the possibility of being able to forward traffic to all other sites.the telco switch makes the forwarding decision based on an address in the packet header.

PAP :

Password Authentication Protocol.An authentication protocol that allows PPP peers to authenticate one another.Unlike challenge handshake Authentication Protocol (CHAP),PAP passes the password and the host name or username in the clear (uncrypted).PAP is supported only on PPP lines.

Permit :

An action taken with an ACL hat implies that the packet is allowed to proceed through the router and be forwarded.

Poison reverse :

A routing update that explicity indicates that a network or subnet is unreachable,rather than implying that a network is unreachable by not including it in updates.poison reverse updates are sent to defeat large routing loops.

Port :

A TCP/IP transport layer header field found in TCP and UDP headers.Ports are numbers,and each numbered port is associated with a specific process.For example,SMTP is associated with port 25.

PPP :

Point-to-Point Protocol.A data- link protocol that provides router –to-router and hos-to-network connections over synchronous circuits.PPP was designed to work with several network layer protocols,such as IP,IPX,and Apple Talk Remote Access (ARA).

PRI :  

Primary Rate Interface.An ISDN interface to primary rate access consists of a single 64-kbps D channel plus 23 (T1) or 30 (E1) B channels for voice  or data.

Private addresses :

IP addresses in several Class A,B,and C networks that are set aside for use inside private organizations.These addresses,as defined in RFC 1918,are not routable through the internet.
