2.9.9.2 Public and Private Peering
The M10/M5 is also an ideal solution for peering, both public and private.
Peering links tend have higher utilization than subscriber access links of
comparable speed. Thus, for peering, performance really matters. The
Internet Processor II's 40 Mpps lookup performance enables providers to
concentrate multiple peering links at up to gigabit speeds on a single
chassis. Or, alternatively, the M10/M5's compact design offers the option to
spread peering links across boxes and design for reliability without
consuming a large amount of rack space.
A rock-solid BGP implementation is also an important requirement for
peering applications. The JUNOS implementation of BGP is capable of
scaling with stability to handle the largest Internet routing tables. The
JUNOS policy engine provides operators full flexibility for supporting and
monitoring peering relationships and making route filtering/advertising
decisions. Configuration tools like commit-and-rollback, off-line policy test,
partitioned operator access permission levels, and configuration change
history, help providers manage complex policy configurations. In addition,
Chaser's Gigabit Ethernet and Fast Ethernet interface support source MAC
filters for public peering applications that use GE or FE as an interconnect.
2.9.9.3 Content Sites
The M10/M5's GE and FE density and performance make it attractive for
content site applications. The M10/M5's GE and FE interfaces support line
rate performance even at small packet sizes. The interfaces also supports
large-MTU frames (9K bytes). JUNOS supports Virtual Router Redundancy
Protocol (VRRP, RFC 2338) to enable a backup default router--and a backup
exit path from the LAN-- in case the primary goes down. VRRP functionality
is transparent to the hosts on the LAN. JUNOS also supports VLANs
(802.1q) to enable providers to partition a single physical GE or FE interface
into multiple virtual interfaces. The GE and FE interfaces have been tested
for interoperability with the leading switch vendors.
2.9.9.4 Backbone Core
The M10/M5 offers the performance to scale backbone networks to OC-
48/STM-16 speeds. Additionally, JUNOS supports many essential tools for
operating fast-growing, large-scale backbone networks. These tools include
scalable Interior Gateway Protocols, including IS-IS and OSPF, a full-scale
MPLS-based traffic engineering implementation and constraint-based routing
to automate the traffic engineering process. The MPLS Circuit Cross-
Connect feature enables providers to transparently tunnel ATM, Frame
Relay, PPP or Cisco HDLC traffic across an IP backbone, allowing providers
to get the most leverage out of their IP infrastructure. The M10/M5 also
supports circuit protection mechanisms such as VRRP, APS, and MPLS fast
reroute.
2.9.9.5 Summary of target applications
Whether it be high-speed access, public or private peering, content site, or
backbone core applications, the M10/M5 and JUNOS offer a wide range of
features designed to provide performance and flexibility while also
maintaining network reliability. Additionally, the M10/M5 hardware design
and the JUNOS software are both proven technologies that are running the
world’s largest provider networks. As a complement to the larger M160,
M40, and M20, the M10/M5 extends the product family and delivers the
Juniper's market-leading hardware performance and software stability in an
