Chapter 3 JUNOS Internet Software Overview The JUNOS Internet software is especially designed for the large production networks typically supported by Internet Service Providers (ISPs). It incorporates Internet Protocol (IP) routing software and software for management of interfaces, networks, and the router chassis. The JUNOS Internet software runs on the Routing Engine.
M160 Internet Router Hardware Guide VPNs on page 48 Interface Process on page 49 Chassis Process on page 49 SNMP and MIB II Processes on page 49 Management Process on page 49 Routing Engine Kernel on page 49 Routing Protocol Process The JUNOS software routing protocol process controls the routing protocols that run on the router. The routing protocol process starts all configured routing protocols and handles all routing messages.
JUNOS Internet Software Overview with JUNOS routing policy, provides a system of administrative checks and balances that can be used to implement peering and transit agreements. ICMP—Internet Control Message Protocol router discovery is a method that hosts can use to discover the addresses of operational routers on a subnet.
M160 Internet Router Hardware Guide paths. LSPs created by LDP can also traverse LSPs created by Resource Reservation Protocol (RSVP). MPLS—Multiprotocol Label Switching enables you to configure LSPs through a network either manually or dynamically. You can control how traffic traverses the network by directing it through particular paths, rather than relying on an IGP’s least-cost algorithm to choose a path.
JUNOS Internet Software Overview Routing and Forwarding Tables The primary function of the JUNOS routing protocol process is maintaining routing tables and using the information in them to determine active routes to network destinations. It copies information about the active routes into the Routing Engine’s forwarding table, which the JUNOS kernel copies to the Packet Forwarding Engine.
M160 Internet Router Hardware Guide In addition, IGPs (IS-IS, OSPF, and RIP) export the direct (interface) routes for the interfaces on which the protocol is explicitly configured. For each routing table, you can affect the routes that a protocol places into the table and the routes from the table that the protocol advertises by defining one or more routing policies and then applying them to the specific routing protocol.
JUNOS Internet Software Overview by a VPN customer with connections to several various ISPs, or different connections to the same ISP in various geographic regions. Carrier-of-Carrier VPNs—Carrier-of-carrier VPNs allow a VPN service provider to supply VPN service to a customer who is also a service provider. The latter service provider supplies Internet or VPN service to an end customer.
M160 Internet Router Hardware Guide Tools for Accessing and Configuring the Software The JUNOS CLI is the primary tool for accessing and controlling the JUNOS Internet software. You use it when accessing the router through the console or a connection to an out-of-band management network. The CLI includes commands for configuring router hardware, the JUNOS Internet software, and network connectivity. The JUNOS CLI is a straightforward command interface.
Chapter 4 System Architecture Overview The router architecture consists of two major components: Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding. Routing Engine—Provides Layer 3 routing services and network management. The Packet Forwarding Engine and the Routing Engine perform independently but communicate constantly through a 100-Mbps internal link.
M160 Internet Router Hardware Guide The Packet Forwarding Engine architecture includes the following components: Midplane—Transports packets, notifications, and other signals between the FPCs and the Packet Forwarding Engine (as well as other system components). Physical Interface Card (PIC)—Physically connects the router to fiber-optic or digital network media. A controller ASIC in each PIC performs control functions specific to the PIC media type.

Preparing for Router Installation Fiber Optic and Network Cable Specifications The router supports PICs that use various kinds of network cable, including multimode and single-mode fiber-optic cable. For information about the type of cable used by each PIC, see the M160 Internet Router PIC Guide. Signal Loss in Multimode and Single-Mode Fiber-Optic Cable Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber).
M160 Internet Router Hardware Guide Dispersion is the spreading of the signal in time. The following two types of dispersion can affect an optical data link: Chromatic dispersion—The spreading of the signal in time resulting from the different speeds of light rays. Modal dispersion—The spreading of the signal in time resulting from the different propagation modes in the fiber.
Preparing for Router Installation Calculating Power Margin for Fiber-Optic Cable After calculating a link’s power budget (using the equation described in “Calculating Power Budget for Fiber-Optic Cable” on page 72), you can calculate the power margin (PM), which represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget (PB).
M160 Internet Router Hardware Guide PM = PB – LL PM = 13 dB – 2 km (1.0 dB/km) – 5 (0.5 dB) – 2 (0.5 dB) – 0.5 dB [HOL] – 1 dB [CRM] PM = 13 dB – 2 dB – 2.5 dB – 1 dB – 0.5 dB – 1 dB PM = 6 dB The following sample calculation for an 8 km-long single-mode link with a power budget (PB) of 13 dB uses the estimated values from Table 18 to calculate link loss (LL) as the sum of fiber attenuation (8 km @ 0.5 dB/km, or 4 dB) and loss for seven connectors (0.5 dB per connector, or 3.5 dB).
Preparing for Router Installation Interface Panel (CIP). You can also connect the router to external alarm-reporting devices through the alarm relay contacts on the CIP. (For more information, see Connector Interface Panel (CIP) on page 32.) Table 19 lists the specifications for the cables that connect to management ports and the wires that connect to the alarm relay contacts.
