This section highlights new NCS 4000 features for Release 6.1.42 :
Software
The following software features have been introduced in Release 6.1.42:
Bidirectional Forwarding Detection (BFD)
BFD is a detection protocol designed to provide fast forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols. In addition to fast forwarding path failure detection, BFD provides a consistent failure detection method for network administrators.
BFD provides fast BFD peer failure detection times for Interior Gateway Protocols (IGP) - OSPF and IS-IS. BFD sends rapid failure detection notices to the routing protocols in the local router to initiate the routing table recalculation process. This results in significantly reducing the overall network convergence time.
BGP Route Reflect (RR)
Border Gateway Protocol (BGP) is an Exterior Gateway Protocol (EGP) that allows you to create loop-free interdomain routing between autonomous systems.
BGP requires that all internal BGP (iBGP) speakers to be fully meshed. However, this requirement does not scale well when there are many iBGP speakers. Configuring the route reflectors is one method to reduce the iBGP mesh in the network and allow all iBGP speakers within an autonomous network to learn about the available routes without introducing loops.
To configure a route reflector you have to tell the router whether the other iBGP router is a client or non-client. A client is an iBGP router that the route reflector will “reflect” routes to and the non-client is just a regular iBGP neighbor.
CFM/Y.1731, Link OAM
Ethernet Connectivity Fault Management (CFM) is an end-to-end, per-service-instance Ethernet layer operations, administration, and maintenance (OAM) protocol. It includes proactive connectivity monitoring, fault verification, and fault isolation for large Ethernet MANs and WANs. "End-to-end" can mean PE-to-PE or CE-to-CE. A service can be identified as a service provider VLAN (S-VLAN) or an Ethernet Virtual Connection (EVC) service.
Link OAM allows network operators to monitor and troubleshoot a single Ethernet link. It is an optional sublayer implemented in the Data Link Layer between the Logical Link Control (LLC) and MAC sublayers of the Open Systems Interconnect (OSI) model. You can monitor a link for critical events and, if needed, put a remote device into loopback mode for link testing. Link OAM also discovers unidirectional links, which are created when one transmission direction fails.
Channelization
Channelization is used to create multiple lower order ODU from higher order ODU for bandwidth sharing. This release supports channelization with packet interfaces.
Ethernet Local Management Interface
Ethernet Local Management Interface (E-LMI) is an asymmetric protocol that runs on the Provider Edge (PE) to Customer Edge (CE) link. The user-facing Provider Edge (uPE) device uses E-LMI to communicate status and configuration parameters of Ethernet Virtual Circuits (EVCs) available on the User-Network Interface (UNI) to the CE device. E-LMI defines the message formats and procedures for conveying the information from uPE to CE.
Ethernet Remote Port Shutdown
Ethernet virtual circuits (EVCs) define a Layer 2 bridging architecture that supports Ethernet services. An EVC is defined by the Metro-Ethernet Forum (MEF) as an association between two or more user network interfaces that identifies a point-to-point or multipoint-to-multipoint path within the service provider network. An EVC is a conceptual service pipe within the service provider network.
Flex-LSP
Flex LSP also known as Associated Bidirectional LSPs is the combination of static bidirectional MPLS-TP and dynamic MPLS-TE. Flex LSP provides bidirectional label switched paths (LSPs) set up dynamically through Resource Reservation Protocol–Traffic Engineering (RSVP-TE). It does not support non-co routed LSPs. Flex Label Switched Paths are LSP instances where the forward and the reverse direction paths are setup, monitored and protected independently and associated together during signaling. You use a RSVP Association object to bind the two forward and reverse LSPs together to form either a co-routed or non co-routed associated bidirectional TE tunnel. You can associate a protecting MPLS-TE tunnel with either a working MPLS-TE LSP, protecting MPLS-TELSP, or both. The working LSP is the primary LSP backed up by the protecting LSP. When a working LSP goes down, the protecting LSP is automatically activated. You can configure a MPLS-TE tunnel to operate without protection as well.
Frequency synchronization
Frequency synchronization is the ability to distribute precision frequency around the network. Precision frequency is required in the next generation networks for applications such as circuit emulation. To achieve compliance to ITU specifications for TDM, differential method circuit emulation must be used, which requires a known, common precision frequency reference at each end of the emulated circuit.
IS-IS
The Intermediate System-to-Intermediate System (IS-IS) routing protocol is an Interior Gateway Protocol (IGP) standardized by the Internet Engineering Task Force (IETF) and commonly used in large Service Provider networks. IS-IS may also be deployed in extremely large Enterprise networks. IS-IS is a link-state routing protocol, providing fast convergence and excellent scalability. Like all link-state protocols, IS-IS is very efficient in its use of network bandwidth.
IS-IS uses OSI protocols to deliver its packets and establish its adjacencies. IS-IS routers need to be assigned OSI addresses, which they use as a Router ID to create network structure.
L2Xconnect/VLAN/EVC
Layer 2 Virtual Private Network (L2VPN) emulates the behavior of a LAN across an L2 switched, IP or MPLS-enabled IP network, allowing Ethernet devices to communicate with each other as they would when connected to a common LAN segment. Point-to-point L2 connections are vital when creating L2VPNs.
Link Aggregation
Link Aggregation (LAG) is a mechanism used to aggregate physical interfaces or ports to create a logical entity called link bundle. LAG is a trunking technology that groups together multiple full-duplex Ethernet interfaces to provide fault-tolerant high-speed links between switches, routers, and servers. This release supports only L2 LAG.
Following are supported with LAG:
-
VLAN subinterfaces on ethernet link bundles
-
LAG through Link Aggregation Control Protocol (LACP)
-
Connectivity Fault Management (CFM) protocol with ethernet bundles
-
QoS over Bundles
MPLS-TE
MPLS-TE software enables an MPLS backbone to replicate and expand upon the traffic engineering capabilities of Layer 2 ATM and Frame Relay networks. MPLS-TE is essential for service provider and Internet service provider (ISP) backbones. Such backbones support a high use of transmission capacity, and the networks must be very resilient so that they can withstand link or node failures. MPLS-TE provides an integrated approach to traffic engineering. With MPLS, traffic engineering capabilities are integrated into Layer 3, which optimizes the routing of IP traffic.
Orchestrated Line Card Reload (OLR)
Hitless upgrade(s) using ISSU is possible only when the SDKs are compatible. For packet-features, a software upgrade includes a change in the SDK resulting in the traffic getting affected. OLR is a solution wherein, the user can upgrade the software without an impact on the traffic, even when the SDKs are not compatible. For OTN-only nodes, OLR is not required.
OSPF/IPV4
Open Shortest Path First (OSPF). OSPF is an Interior Gateway. Protocol (IGP) developed by the OSPF working group of the Internet Engineering Task Force (IETF). OSPF was designed expressly for IP networks and it supports IP subnetting and tagging of externally derived routing information. OSPF also allows packet authentication and uses IP multicast when sending and receiving packets.
QoS
Quality of Service (QoS) is the technique of prioritizing traffic flows and providing preferential forwarding for higher-priority packets. The fundamental reason for implementing QoS in a network is to provide better service for certain traffic flows. A traffic flow can be defined as a combination of source and destination addresses, source and destination socket numbers, and the session identifier. The traffic flow must be identified, classified, and prioritized on all routers and passed along the data forwarding path throughout the network to achieve end-to-end QoS delivery. The key QoS techniques are:
-
QoS Classification - involves categorizing a packet within a specific group (or class) and assigning it a traffic descriptor to make it accessible for QoS handling on the network. The traffic descriptor contains information about the forwarding treatment (quality of service) that the packet should receive.
-
Policing - allows the user to control the maximum rate of traffic sent or received on an interface and to partition a network into multiple priority levels or class of service (CoS).
-
Qos Marking - Marking is a process, which helps to modify QOS fields incoming and outgoing packets. Unconditional and conditional packet marking feature provides users with a means for efficient packet marking by which the users can differentiate packets based on the designated markings.
-
Dropping technologies (Tail Drop and WRED) - Tail drop is a congestion avoidance technique that drops packets when an output queue is full until congestion is eliminated. WRED drops packets selectively based on IP precedence.
-
Shapers and policers - are needed to ensure that a packet adheres to a contract and service. A policer typically drops traffic flow; whereas, a shaper delays excess traffic flow using a buffer, or queuing mechanism, to hold the traffic for transmission at a later time.
For more information about QoS, see the Quality of Service Configuration Guide for Cisco NCS 4000 Series.
SRLG
Announce SRLG : Enabling SRLG Announce on Ethernet Terminated ODU to pass on the SRLG from OTN layer to packet interfaces.
SRLG Inheritance : SRLG values configured for optics controllers get inherited to underlying ethernet interfaces and sub-interfaces.
VPWS
Virtual Private Wire Services (VPWS), also known as Ethernet-over-MPLS (EoMPLS), allow two L2VPN Provider Edge (PE) devices to tunnel the Ethernet traffic through an MPLS-enabled L3 core and encapsulates Ethernet protocol data units (PDUs) inside MPLS packets (using label stacking) to forward them across the MPLS cloud. The two L2VPN PEs are typically connected at two different sites with an MPLS core between them. The two attachment circuits (ACs )connected at each L2VPN PE are linked by a pseudo wire (PW) over the MPLS network, which is the MPLS PW. The pseudo wire is a virtual point-to-point circuit. The two PEs establish an MPLS LDP targeted session between themselves so they can establish and control the status of the PW. An MPLS LDP targeted session is a label distribution session between routers that are not directly connected. When you create an MPLS traffic engineering tunnel interface, you need to establish a label distribution session between the tunnel headend and the tailend routers.
You can use the Pseudowire Call Admission Control (PW CAC) process to check for bandwidth constraints and ensure that after the path is signaled, the links (pseudowires participating in the bidirectional LSP association have the required bandwidth. Only pseudowires with sufficient bandwidth are admitted in the bidirectional LSP association process. The PW CAC feature works only when the PW is configured with a L2VPN preferred path tunnel.
VPWS Scale
1000 VPWS sessions are supported on each line card and 4000 VPWS sessions are supported on a node.
For more information on the above software features, see the Configuration Guide for Cisco NCS 4000 Series.
