The OSI Model
Established in 1947, the International Standards Organization (ISO) is a multinational body dedicated to worldwide agreement on international standards. An ISO standard that covers all aspects of network communications is the Open Systems Interconnection (OSI) model. It was first introduced in the late 1970s.

La Capa Fisica
The physical layer is responsiblefor the movement of individual bits from one hop (node) to the next.
© 2007 Marlene Prado, All rights reserved. Comsoc UNI 30
La Capa de Enlace de Datos
The data link layer is responsible for moving frames from one hop (node) to the next.
© 2007 Marlene Prado, All rights reserved. Comsoc UNI 32
La Capa de Red
The network layer is responsible for the delivery of individual packets from the source host to the destination host.
© 2007 Marlene Prado, All rights reserved. Comsoc UNI 34
Capa de Transporte
The transport layer is responsible for the delivery of a message from one process to another
© 2007 Marlene Prado, All rights reserved. Comsoc UNI 35
Reliable process-to-process delivery of a message

TCP/IP Protocol Suite
The TCP/IP protocol suite is made of five layers: physical, data link, network, transport, and application. The first four layers provide physical standards, network interface, internetworking, and transport functions that correspond to the first four layers of the OSI model. The three topmost layers in the OSI model, however, are represented in TCP/IP by a single layer called the application layer.

DIRECCIONAMIENTO
Three different levels of addresses are used in an internet using the TCP/IP protocols: physical (link) address, logical (IP) address, and port address.

Relationship of layers and addresses in TCP/IP
© 2007 Marlene Prado, All rights reserved. Comsoc UNI 46
Ejemplo 1:
In la figure a node with physical address 10 sends a frame to a node with physical address 87. The two nodes are connected by a link. At the data link level this frame contains physical (link) addresses in the header. These are the only addresses needed. The rest of the header contains other information needed at this level. The trailer usually contains extra bits needed for error detection.
© 2007 Marlene Prado, All rights reserved. Comsoc UNI 47
Ejemplo 2:
Most local area networks use a 48-bit (6 bytes) physical address written as 12 hexadecimal digits, with every 2 bytes separated by a colon as shown below:
07:01:02:01:2C:4B
A 6-byte (12 hexadecimal digits) physical address.

Example 3
We want to send data from a node with network address A and physical address 10, located on one LAN, to a node with a network address P and physical address 95, located on another LAN. Because the two devices are located on different networks, we cannot use link addresses only; the link addresses have only local jurisdiction. What we need here are universal addresses that can pass through the LAN boundaries. The network (logical) addresses have this characteristic.
© 2007 Marlene Prado, All rights reserved. Comsoc UNI 49
Ejemplo 3 (cont)
The packet at the network layer contains the logical addresses, which remain the same from the original source to the final destination (A and P, respectively, in the figure). They will not change when we go from network to network. However, the physical addresses will change as the packet moves from one network to another. The boxes labeled routers are internetworking devices, which we will discuss in Chapter 3.

MPLS OVERVIEW1a. Existing routing protocols (e.g. OSPF, IS-IS) establish reachability to destination networks
1b. Label Distribution Protocol (LDP) establishes label to destination network mappings.
2. Ingress Edge LSR receives packet, performs Layer 3 value-added services, and “labels”packets
3. LSR switches packets using label swapping
4. Edge LSR at egress removes label and delivers packet
