In keeping with the unofficial Differentiated Services design principle of marking traffic as close to its source as possible, IP phones mark voice-bearer traffic (to DSCP EF) and Call-Signaling traffic (currently, to DSCP AF31, but this will soon change to DSCP CS3) on the phones themselves. Some IP/VC devices mark Interactive-Video traffic to AF41 on their network interface cards (NICs).
However, as has already been discussed, it is not recommended that end-user PCs be trusted to set their CoS/DSCP markings correctly because users easily can abuse this (either unintentionally or deliberately). Therefore, application traffic that originates from untrusted hosts should be marked on network audit freeware.

Network controls
DSCP-to-CoS remapping is optional. Newer network controls perform QoS based on internal DSCP values that are generated either by trusted DSCP markings or by trusted CoS markings (coupled with CoS-to-DSCP mappings). In the case of legacy switches at the branch that perform QoS strictly by preset CoS values, CoS might need to be remapped on the branch router's LAN edge.
Enhanced packet marking (Cisco IOS Release 12.2[13]T or higher) is the optimal tool for resetting CoS values because it uses a table. In this manner, a default DSCP-to-CoS mapping can be used without having to configure explicitly a class-based marking policy that matches every class and performs a corresponding set cos function.

Network pc audit
The LAN edge of the network pc audit can have egress and ingress policies. Because you have been dealing with egress policies since the WAN/branch discussion began, and because the egress policies are not only optional, but also considerably simpler, they are discussed first.
As previously mentioned, it is better to mark at Layer 3 (DSCP) instead of Layer 2 whenever possible because Layer 2 markings are lost when the transmission medium changes. This is the case with any Ethernet 802.1Q/p CoS values that have been set within the campus and are carried over a WAN (or VPN). In some cases, network administrators prefer to have these markings restored at the branch; DSCP-to-CoS mapping then can be performed on the branch router's LAN edge.

Simple inventory software
Second, if the combined WAN circuit rate is significantly below 100 Mbps, enable egress shaping on the Catalyst switches (when supported).
If there is no hope of engaging queuing on the simple inventory software because the combined WAN circuit rates are far below those of Fast Ethernet, enable shaping on platforms that support this feature.
For example, if a branch router is using two ATM-IMA T1 links (3 Mbps combined throughput) to connect the branch to the WAN, the branch switch could be configured to shape all WAN-destined traffic to 3 Mbps or could be configured to shape on a per-application basis to smaller increments

Network assessment software
The threat posed by any strict priority-scheduling algorithm is that it could starve lower-priority traffic. To prevent this, the LLQ mechanism has a built-in policer. This policer (like the queuing algorithm itself) engages only when the interface is experiencing congestion. Therefore, it is important to provision the priority classes properly. If the total amount of priority class bandwidth provisioned is lower than the total amount of voice traffic offered to the PQ (including the Layer 2 overhead), the excess voice traffic might be dropped (by the LLQ policer). As with any other policer, LLQ's policer, when engaged, drops traffic indiscriminately and affects the quality of all voice calls active on the interface (not just the last one to go through). In earlier network assessment software Releases, the PQ of LLQ policed strictly to the bandwidth assigned, regardless of traffic present or absent in other classes. In later releases, this operation changed to police strictly only if the interface was congested that is if other classes were underutilized, PQ traffic would be allowed to exceed its bandwidth without dropping packets
Another benefit provided by the implicit policer within the LLQ mechanism is the capability to use TDM for the single strict-priority queue. TDM abstracts the fact that only a single strict-priority queue exists and allows for the configuration and servicing of "multiple" low-latency queues.

Network security audits
The oldest queuing algorithm is PQ, which consists of only four queues (high, medium, normal/default, and low). The scheduler begins by emptying the high queue and begins to service lower queues only when upper queues are completely empty. This basic algorithm proved very successful in handling real-time traffic, but it posed starvation possibilities to lower-priority traffic flows.
A major difference between WFQ and CBWFQ is that, with WFQ, network security audits is calculated instantaneously; but with CBWFQ, a minimum bandwidth explicitly is defined and enforced. Additionally, CBWFQ uses Modular QoS CLI (MQC)based class maps for classification, which provide the richest and most granular recognition criteria within the IOS QoS toolset. When class maps are combined with CBWFQ bandwidth statements, minimum-bandwidth guarantees can be provisioned for almost any application

Computer audit software
Layer 3 queuing subsystems operate at the network layer and are applied to Layer 3 packets at a logical level. Because IOS Layer 3 queuing subsystems are independent of the egress interface type, they can be applied to Asynchronous Transfer Mode (ATM), Frame Relay, High-Level Data Link Control (HDLC), Point-to-Point Protocol (PPP), Multilink Point-to-Point Protocol (MLP), or tunnel interfaces. It is important to recognize that Layer 3 queuing typically considers only the IP overhead in its bandwidth provisioning. Layer 2 overhead such as the ATM cell tax is not factored into the equation and, therefore, must be provisioned explicitly for drop-sensitive applications such as Voice over IP (VoIP).
There is a long history of queuing algorithms in computer audit software, not all of which are covered in this chapter because they are not applicable to QoS deployment for converged networks. Newer queuing and scheduling algorithms are simply combinations and enhancements of older queuing algorithms. For a historical perspective and an understanding of why these mechanisms are insufficient for today's converged networks, it is helpful to review some of these legacy queuing techniques.

Inventory asset management
The buffer space (or memory) for queues is finite in capacity and acts very much like a funnel for water that is being poured into a small opening. If water continually is entering the funnel much faster than it exits, eventually the funnel begins to overflow from the top. When queuing buffers begin overflowing, packets might be dropped either as they arrive (tail drop) or selectively, before all buffers are filled. Selective dropping of packets when the queues are filling is referred to as congestion avoidance. Congestion-avoidance mechanisms work best with TCP-based applications because selective dropping of packets causes the TCP windowing mechanisms to throttle back and adjust the rate of flows to manageable rates.
Congestion-avoidance mechanisms are complementary to queuing algorithms and are discussed in more detail in Congestion-Avoidance Tools. The relationship between congestion-management tools (or scheduling algorithms) and inventory asset management is as follows: With congestion management, the scheduling algorithms manage the front of a queue; with congestion avoidance, the mechanisms manage the tail of a queue.

It controls
Only the CIR and PIR values can be specified with percent, not the burst sizes; the burst sizes are configured in units of milliseconds. If the CIR is configured in percent, the PIR also must be. When the service-policy is attached to an interface, the CIR (and PIR, if configured) is determined as a percentage of the interface bandwidth. If it controls is changed, the CIR and PIR values and burst sizes automatically are recalculated using the new interface bandwidth value. For subinterfaces, the bandwidth of the main interface is used for the calculation. For ATM, the VC bandwidth is used; for Frame Relay, the CIR value of the PVC is used.
Scheduling is the process of deciding which packet to transmit next. Scheduling occurs when the interface is experiencing congestion, but also (unlike queuing) when the interface is not experiencing congestion (that is, there is still a decision, albeit a simple one, of which packet should be transmitted next, even if there is no congestion on the interface). If there is no congestion on the interface, packets are transmitted as they arrive. If the interface is experiencing congestion, queuing algorithms are engaged. However, the scheduler still has to decide which queue to service next

Network audit freeware
RFC 2697 and RFC 2698 describe three-color policers, meaning that the packets can be colored to three separate values to indicate whether they conform to, exceed, or violate the policing conditions. The single-rate three-color marker and the two-rate three-color marker initially were implemented (in IOS Software Releases 12.2[2]T and 12.2[4]T, respectively) to operate in color-blind mode. This means that the policer assumes that the packet stream previously was uncolored. The RFCs also define a color-aware mode, which means that the policer assumes that some preceding entity already has colored the packet stream. At the time of this writing, the color-aware mode is available only in IOS Software Release 12.0.26S; it is not yet available in any 12.2T release.
Most networks contain a wide array of interfaces with network audit freeware. If absolute bandwidth rates are used in policing policies, the policy must be re-entered for each different interface size. This reduces policy modularity and makes policy management more cumbersome across the enterprise. It often is desirable to have an overall network policy in which, for example, FTP traffic is not to exceed 10 percent of the bandwidth on any interfaceregardless of absolute speed. This can be achieved using percentages in the policing statements. Thus, a single policy can be reused across many interfaces in the network

Network controls
It is advantageous to police some applications at multiple levels. For example, it might be desirable to limit all TCP traffic to 10 Mbps, while at the same time limiting FTP traffic (which is a subset of TCP traffic) to no more than 1.5 Mbps. To achieve this nested policing requirement, network controls can be used. Two-level hierarchical policing was introduced in IOS Software Release 12.1(5)T. Later, in Release 12.2.1(3)T, three-level hierarchical policing was introduced for the 7200 and 7500 platforms
The policer at the second level in the hierarchy acts on packets transmitted or marked by the policer at the first level. Therefore, the second level does not see any packets that the first level drops. The sum of packets that the lower-level policers see is equal to the sum of packets that the higher-level policer transmits or marks. This feature supports up to three nested levels
