Chapter 1 Overview
Feature Category Item
Quality of Service -- Generic Committed Access Rate (CAR)
Cisco Express Forwarding (CEF)
Weighted Random Early Detection (WRED)
TAG/NetFlow Switching including Type of Service (ToS) Support
Weighted Fair Queuing (WFQ)
Weighted Fair Drop (WFD) enhancements to associate a maximum bandwidth in kbps
with a particular setting of IP ToS bits; can be used to ensure that basic data traffic does
not exceed a pre-set rate limit and thereby interfere with higher priority traffic such as
voice
Common Open Policy Service (COPS) for Resource Reservation Protocol (RSVP) to
support admission control, bandwidth guarantee, media-independent reservation, data
classification, and data policing
Rate Limiting and Shaping -- Limiting the data rate to and from a CM or STB, and shaping traffic per DOCSIS such
DOCSIS
that TCP behavior is not adversely impacted by downstream and upstream rate limiting
or shaping; MAC scheduler supports traffic shaping of downstream and upstream traffic
to ensure a single CM or STB does not consume all of the channel bandwidth and allow
the CMTS administrator to configure different maximum data rates for different
subscribers; traffic shaping feature delays the scheduling of upstream packets which
allows the TCP/IP stack to pace application traffic appropriately and approach
throughput commensurate with the subscriber’s defined QoS levels
Routing Protocols Border Gateway Protocol (BGP)
Intermediate System-to-Intermediate System (IS-IS)
Open Shortest Path First (OSPF)
Interior Gateway Routing Protocol (IGRP)
Enhanced Interior Gateway Routing Protocol (EIGRP)
Routing Information Protocol (RIP)
Security Features -- DOCSIS 56-bit and 40-bit Baseline Privacy Interface (BPI) Data Encryption Standard (DES)
Security Features -- Generic Standard and extended access lists
Authentication, Authorization & Accounting (AAA)
Radius authentication
Internet Key Exchange (IKE)?
Terminal Access Controller Access Control System Plus (TACACS+)
Cisco IOS Firewall Enhancements
Hypertext Transfer Protocol (HTTP) Security
Service Assurance Agent Application-aware agent that monitors network performance by measuring key service
level agreement (SLA) metrics such as response time, availability, jitter (interpacket
delay variance), connect time, throughput, packet loss and application performance;
enhanced UDP latency reporting
