CISCO-CASA-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

        DESCRIPTION
                "This MIB contains the basic objects for managing a
                Cisco Appliance Services Architecture (CASA) Entity. A
                CASA Entity can be a Manager or a Forwarding Agent as
                defined below. The basic objects included in this mib
                are those to configure CASA, retrieve CASA's state and
                information about the fixed affinity cache.
                
                The following gives a list of definitions and a
                description of how Service Managers and Forwarding
                Agents interact. For a more detailed description, see
                the Cisco Appliance Services Architecture (CASA)
                document.
                
                CASA is a protocol allowing software entities (called
                Appliances, examples are web caches, firewalls, load
                balancers) to control the behavior of network hardware
                devices (called Forwarding Agents, examples are
                switches or routers) by providing a set of rules used
                to handle network traffic.

                A Network Appliance (referred to as an Appliance) is
                any subsystem whose purpose is to provide a specific
                additional value-added service to the network device,
                and could be implemented as a standalone box, a line
                card or processor card, or a software subsystem.
                Examples of Network Appliances would include Load
                Balancers, WebCaches, and Firewalls.

                An Appliance tells Fowarding Agents how to handle
                packets based on their source and destination IP
                addresses and ports, and IP protocol fields.  This set
                of information is called an Affinity.
                
                A Service Manager is an Appliance that requests
                packet flows from Forwarding Agents through CASA.
                
                A Real Server is a physical computing engine or part
                of that physical computing engine that offers one or
                more application services to a set of clients in the
                network.
                
                A packet flow is a TCP connection or a sequence of UDP
                packets between a client and a specific Real Server,
                pertaining to a specific application. Flows are
                represented by entries in the affinity cache tables.

                The Service Manager requests packet flows from
                Forwarding Agents by sending Affinities which contains
                wildcards on some of the Affinity fields. Affinities
                that contain wildcards in some of the fields are
                called Wildcard Affinities.  The Service Manager may
                send the Forwarding Agent an Affinity containing
                explicit values for each of the fields.  These
                Affinities are called Fixed Affinities.
                
                Typically Wildcard Affinities are used to instruct the
                Forwarding Agent to send packets received by the
                Forwarding Agent, which match the Wildcard Affinity,
                to the Service Manager. When the Service Manager
                receives the matching packet, the Service Manager
                typically will send the Forwarding Agent a Fixed
                Affinity. The Forwarding Agent uses Fixed Affinities
                to match packets coming from the network, execute any
                processing required on that packet, and forward that
                packet to a destination IP address (designated in the
                Fixed Affinity) called the Dispatch Address.
                
                When an IP packet arrives at the Forwarding Agent, the
                Forwarding Agent attempts to match the packet with the
                Fixed Affinities in the Fixed Affinity cache.  If
                there is no match, an attempt is made to match the
                packet with the list of Wildcard Affinities. If there
                is no match the packet is routed normally. If there is
                a match with a Wildcard Affinity, the Forwarding Agent
                sends the packet to the Service Manager who will send
                the Forwarding Manager a Fixed Affinity which provides
                information on how to process IP packets similar to
                the one received by the Forwarding Agent. Processing
                of such packets may include sending the packet to the
                Service Manager. Such packets are called Interest
                Packets.  Alternatively a Tickle Packet may be sent to
                the Service Manager which is an indication that a
                matched packet has been received by the Forwarding
                Agent.
