to mark and classify traffic based on the IEEE 802.1p standard. CoS values range from 0 to 7, with higher values indicating higher priority. QoS can also use VLAN tags to separate traffic into different logical groups based on the IEEE 802.1Q standard.
Layer 3: QoS can use IP Precedence or Differentiated Services Code Point (DSCP) values to mark and classify traffic based on the IP header. IP Precedence values range from 0 to 7, with higher values indicating higher priority. DSCP values range from 0 to 63, with higher values indicating higher priority and finer granularity. QoS can also use IP addresses or prefixes to identify traffic based on the source or destination.
Layer 4: QoS can use TCP or UDP port numbers to identify traffic based on the application or protocol. For example, QoS can use port 80 for HTTP traffic, port 443 for HTTPS traffic, port 22 for SSH traffic, etc.
Layer 7: QoS can use application signatures or deep packet inspection (DPI) to identify traffic based on the content or behavior. For example, QoS can use signatures to detect Skype traffic, YouTube traffic, Netflix traffic, etc.
QoS can use various techniques and tools to manage and control traffic in data center networks, such as:
Shaping: QoS can use shaping to limit the rate of traffic to a certain level or conform to a certain profile. Shaping can smooth out traffic bursts and prevent congestion and packet loss. Shaping can be applied at the ingress or egress of a network device.
Policing: QoS can use policing to monitor the rate of traffic and take action if it exceeds a certain level or violates a certain policy. Policing can drop or remark packets that exceed the limit or policy. Policing can be applied at the ingress or egress of a network device.
Scheduling: QoS can use scheduling to determine the order and timing of packet transmission based on their priority and availability. Scheduling can use various algorithms, such as First-In First-Out (FIFO), Priority Queueing (PQ), Weighted Fair Queueing (WFQ), Class-Based Weighted Fair Queueing (CBWFQ), Low Latency Queueing (LLQ), etc.
Congestion avoidance: QoS can use congestion avoidance to prevent or reduce congestion and packet loss in data center networks. Congestion avoidance can use various mechanisms, such as Random Early Detection (RED), Weighted Random Early Detection (WRED), Explicit Congestion Notification (ECN), etc.
Link efficiency: QoS can use link efficiency to improve the utilization and performance of data center links. Link efficiency can use various techniques, such as compression, fragmentation, header optimization, etc.
VSG
VSG stands for Virtual Security Gateway. It is a Cisco innovation that provides security and segmentation for virtual machines (VMs) in data center networks. VSG is a virtual appliance that runs on a Cisco Nexus 1000V Series Switch, which is a distributed virtual switch that integrates with VMware vSphere or Microsoft Hyper-V hypervisors. VSG acts as a firewall that filters traffic between VMs based on policies and rules.

Multi-Hop FCoE
Multi-Hop FCoE stands for Multi-Hop Fibre Channel over Ethernet. It is a technology that enables Fibre Channel (FC) traffic to be transported over multiple Ethernet hops in data center networks. FCoE is a protocol that encapsulates FC frames with an Ethernet header and transports them over an Ethernet network. FCoE enables data center professionals to consolidate both Ethernet and FC traffic on a single network, which reduces the complexity and cost of managing multiple networks and devices. FCoE requires Data Center Bridging (DCB), which is a set of enhancements to Ethernet that enable lossless and reliable transmission of FCoE traffic.
Multi-Hop FCoE offers several advantages for data center networks, such as:
High scalability: Multi-Hop FCoE can support up to 32 Ethernet hops and up to 239 FC domains in a single network. Multi-Hop FCoE also enables ECMP across multiple paths and switches, which increases the bandwidth and load balancing capabilities.

LISP
LISP stands for Locator/ID Separation Protocol. It is a protocol that decouples the identity and location of devices in data center networks. LISP uses two types of addresses: Endpoint Identifiers (EIDs) and Routing Locators (RLOCs). EIDs are assigned to devices and identify them regardless of their location. RLOCs are assigned to network devices and identify their location in the network. LISP uses a technique called encapsulation to map EIDs to RLOCs and transport packets between devices.
LISP offers several advantages for data center networks, such as:
High scalability: LISP can support up to 2^128 EIDs and RLOCs in a single network. LISP also enables efficient aggregation and routing of packets by routers and switches.
High availability: LISP provides fast convergence and recovery in case of link or device failures. LISP also supports multiple RLOCs per EID that can be activated or deactivated based on different criteria, such as load, proximity, etc.
High flexibility: LISP allows for seamless mobility of devices without changing their EIDs or losing their connections. LISP also supports multiple EIDs per device that can be activated or deactivated based on different criteria, such as application, user, etc.
High performance: LISP delivers low latency and high throughput for data center applications and workloads. LISP also supports QoS features that enable prioritization and differentiation of traffic based on various parameters, such as EID, RLOC, etc.
High security: LISP provides encryption and authentication for data packets. LISP also supports access control lists (ACLs) that enable filtering of traffic based on various parameters, such as EID, RLOC, etc.
MPLS
MPLS stands for Multiprotocol Label Switching. It is a technology that enables fast and efficient forwarding of packets in data center networks. MPLS uses a technique called label switching to assign labels to packets based on their destination and transport them over a predetermined path called a label switched path (LSP). MPLS switches use the labels rather than the IP headers to forward packets along the LSP.
MPLS offers several advantages for data center networks, such as:
in a single network. MPLS also enables ECMP across multiple paths and switches, which increases the bandwidth and load balancing capabilities.
High availability: MPLS provides fast convergence and recovery in case of link or switch failures. MPLS also supports multiple LSPs per destination that can be activated or deactivated based on different criteria, such as load, priority, etc.
High flexibility: MPLS allows for any-to-any connectivity between endpoints without requiring complex configurations or protocols. MPLS also supports various types of LSPs that can be tailored to different traffic types and requirements, such as point-to-point, point-to-multipoint, multipoint-to-multipoint, traffic engineering, etc.
High performance: MPLS delivers low latency and high throughput for data center applications and workloads. MPLS also supports QoS features that enable prioritization and differentiation of traffic based on various parameters, such as label, CoS, etc.
