PPP over Ethernet

PPP over Ethernet (PPPoE) provides the ability to connect a network of hosts to a Remote Access Server RAS (also called as Network Access Server NAS or Broadband Remote Access Server B-RAS). With this model, each host (or a CPE) utilizes it's own PPP stack. This way access control, billing and type-of-service can be done on a per-user basis. To establish a point-to-point connection over Ethernet, each PPP s ...

PPP Authentication: CHAP

The Challenge Handshake Authentication Protocol (CHAP) (protocol value= 0xC223) is used to verify the identity of the peer using a 3-way handshake. After the Link Establishment Phase is complete, the authenticator sends a "Challenge" message to the peer containing a value. The peer responds with a "Response" message containing a hash-value obtained after performing MD5 on the value sent in the Challenge mes ...

PPP Authentication: PAP

RFC 1334 discusses PPP authentication protocols. The Password Authentication Protocol (PAP) (protocol value=0xC023) is one of two authentication methods available for PPP. PAP uses 2-way handshake to establish its identity with its peer. The Authentication Phase is optional in PPP. This phase starts after Link Establishment Phase is successfully completed. After Link Establishment Phase is complete, the use ...

IPv6 & IPv4 over PPP

In order to establish communication over a point-to-point link, each end of the point-to-point link first sends LCP packet to configure and test the data-link. After the link has been established and optional facilities are negotiated for LCP, PPP sends NCP packets to choose and configure one or more Network Layer protocols. Once each of the chosen network layer protocols have been configured, datagrams fro ...

Understanding PPP

RFC 1661 describes PPP in detail. PPP provides a standard method of transporting multi-protocol datagrams over point-to-point links. PPP has three main components- A way of encapsulating multi-protocol datagrams A Link Control Protocol (LCP) for establishing, configuring & testing data-link connection. A family of Network Control Protocols (NCPs) for establishing & configuring different network-laye ...

Class Selector DSCP Values

The Class Selector (CS) DSCP values provide backward compatibility with IP Precedence. By examining the first 3 bits in each binary DSCP value in the following table, these 8 DSCP values match 8 different values that can be encoded in the 3-bit IP Precedence field.  Name of DSCP Class Selector  Binary Value of DSCP  Equivalent IP Precedence Value  Default  0 0 0 0 0 0 0  CS1 0 0 1 0 0 0  1 CS2 0 1 0 0 0 0   ...

Assured Forwarding and Expedited Forwarding

The Assured Forwarding (AF) PHB contains two separate QoS functions. The first function is Queueing. Each router classifies the packets into 4 different classes, and packets from each classes are placed in seperate queues. The AF PHB does not guarantee that each packet will be delivered and it also does not reserve any minimum bandwidth for each class. The second function defines Congestion Avoidance. RFC 2 ...

CoPP – Control Plane Policing

Definitions: Control Plane (CP): A collection of processes that run at the process level on the route-processor (RP). These processes collectively provide high-level controls for most IOS functions. Central Switch Engine: A device that is responsible for high-speed routing of IP packets. It also performs high-speed input and output services for non-distributed line cards. Distributed Switch Engine: A device ...

QoS for VPN

Network topology: When a packet is encapsulated using GRE for instance or encrypted using IPSec, by default, Cisco IOS router copies the ToS (Type of Service) byte into the new IP header of encapsulated/ encrypted packet from the original IP header. This allows the ISP to look up at least ToS byte to perform QoS functions. However, in some case you might want to perform QoS features on the egress (i.e. outg ...

Priority Queuing

Priority Queuing (PQ) is a Congestion Management technique. PQ schedules traffic such that the higher-priority queues "always" get serviced first. This can cause the traffic of other lower-priority queues to starve out. PQ uses 4 different queues- High, Medium, Normal and Low. If the High queue has a packet waiting, the scheduler will service it first. If there is no packet in the High queue, the scheduler ...
